# What Is The Perfect Angle For Solar Panels?

Is it worth tilting your solar panels? – Yes – your solar panels must collect sunlight to produce solar energy successfully. Therefore, you want to ensure your solar panel is tilted to capture as much sunlight as possible. Therefore, to get the maximum average output from your solar power system, you should tilt your solar panels close to the same angle as the latitude of your home.

## What angle should solar panels be tilted?

Calculation method two – This is an improvement of the general method that gives better results. In this method, the optimum tilt angle for solar panels during winter is calculated by multiplying the latitude by 0.9 and then adding 29°. In the above case example of a latitude of 34°, the tilt angle will be (34 * 0.9) + 29 = 59.6°.

1. This angle is 10° steeper than in the general method but very effective at tapping the midday sun which is the hottest in the short winter days.
2. For summer, the tilt angle is calculated by multiplying the latitude by 0.9 and subtracting 23.5°.
3. In the above case example, this angle would be (34 * 0.9) – 23.5 = 7.1°.

For optimum tilt angles during spring and fall, 2.5° is subtracted from the latitude.

### Do solar panels need to be at a certain angle?

Why is the tilt of the panels so important? – The tilt of the panels is important because your panels will produce a maximum of energy when the sun is directly perpendicular to them. During the winter in the northern hemisphere, for example, the sun is low in relation to the horizon.

## Should solar panels be angled or flat?

Watts – So what’s the optimal angle to tilt your solar panels for maximum returns? In the United States, solar panels are at their most effective if installed on South-facing roofs. It’s commonly agreed that optimal solar energy production will occur when your solar panels face south at a tilt equal to 30°.

## At what angle do solar panels stop working?

What is the Best Angle for Solar Panels

• Welcome to this informative article.
• Do you want to build a really efficient solar power system but you don’t know how to evaluate the correct orientation of the solar panels and how to calculate the perfect angle of inclination?
• No problem, on this page you will find all the information and advice that will allow you to know step by step the correct orientation (azimuth angle) and the best inclination of your panels (tilt angle) according to the seasonal period in which you have higher electricity demand and to the geographical location where you want to install the solar power system.
• In fact, thanks to a mathematical formula and our map of United States latitude, you will learn to calculate the optimal inclination for your city both in the summer and in the winter, without wasting time and for free.
• In which direction should the panels be oriented?

When designing a solar power system it is essential to choose the roof side on which to mount the panels. We must therefore know on which side there is higher solar radiation for the whole day in order to have the maximum possible power production. Since solar panels are more productive when the sun’s rays are perpendicular to their surfaces, the certainly best orientation is the one directly true SOUTH (azimuth angle = 180 °). In the event that installation in the South direction is not possible or we have shading problems (such as a very tall tree), it is possible to slightly change the orientation of the panels. It is in fact useful to know that, if solar panels face outside true south, up to a maximum of 45° (south-east and south-west), the annual production undergoes a rather limited reduction (1-3%).

The solar radiation that the panels receive is almost the same. However, if the panels are turned at an angle greater than 45 ° compared to true south, production begins to decrease significantly. At 90° from true south (therefore east and west), production can drop to 30%, This decline is due to the fact that solar panels, during most of the day, are exposed to weak and not perpendicular sunlight.

These panels will certainly produce solar energy but to a lesser extent than panels facing directly south. What is the optimal tilt angle for solar panels? Well, now that we know that the optimal direction is south, we need to find the optimal tilt angle.

First of all, in the choice of the tilt angle for solar panels on a house roof we are bound to satisfy two basic needs : the need for energy production and the need for an aesthetically pleasing and long-lasting final result. The roof of a house already has its own inclination and slope, so a compromise must be sought between these two needs.

Knowing the optimal angle for production purposes will allow us to choose the best compromise for our installation.

1. If, on the other hand, you wish to build the structure for a sunshade canopy with solar panels or the structure for a ground-mounted solar system or for an innovative parking space covered by or, this guide will be very useful in the design phase of the structure as it will provide you with the optimal inclination angle of the structure relative to the horizontal plane.
2. The optimal tilt angle that our solar panels will have is essentially influenced by two factors: • the latitude of the geographical place where we want to mount them
3. • the time of year when we need more energy

How does latitude affect angle of inclination? As I said earlier, the more a is perpendicular to the sun’s rays, the more it produces electricity. The maximum energy production is achieved at midday, when the sun reaches its maximum altitude on the horizon. As many of you already know, there is a day of the year in which we have less hours of light and a day of the year in which we have more hours of light. These days are called, • winter solstice • summer solstice The summer solstice, in which we have more hours of light, is 20 or 21 June and the sun at midday is at its highest annual altitude (see figure); while the winter solstice, in which we have less hours of light, is December 21 or 22 and the midday sun is at its lowest annual altitude (see figure).

Based on the latitude in which we live, the maximum and minimum annual altitude of the sun at midday also changes, As can be seen from the figure below (map credit: Mapsofworld.com ), the latitude of Continental United States is between about 49° North (Alaska excluded), up to just over 26° South (Texas).

To know the altitude of the Sun during the summer and winter solstice, we just have to identify the degrees of latitude in which we want to install our solar power system. Let’s look at the figure below. For example, if we are in Chicago, the latitude will be around 42°. Calculating maximum Sun height at noon Once the latitude has been identified, we must subtract 23° (current approximate angle of the Earth’s tilt). The last mathematical operation is: 90 – (result obtained). In the case of Chicago we will have the culmination point of the Sun at 71°, obtained from the calculation 90 – (42-23).

To get the maximum energy efficiency during the summer solstice, the solar panels in Chicago must face SOUTH and be tilted 19° (90-71). In this way, at noon the panels will be perfectly perpendicular to the sun’s rays. Calculating minimum Sun height at noon To calculate the sun height at midday during the winter solstice, instead of subtracting, we must add 23°.

The subsequent mathematical operation remains unchanged. The result for Chicago is 90 – (42 + 23) = 25°, To get maximum energy efficiency during the winter solstice, the solar panels in Chicago must face SOUTH and be tilted 65° (90-25). In this way, at noon the panels will be perfectly perpendicular to the sun’s rays. From the calculations it is immediately evident that a high tilt angle of the panels will favor a greater energy production during the winter season, while a low tilt angle of the panels will favor a greater energy production during the summer season.

Which tilt angle to choose for our system? Simple, the one that meets our energy needs, If we are in Chicago and we need energy only in the winter season it is good to choose a tilt angle between 53° and 65° (example 59°), while if we need only in the summer it is good to choose a tilt angle between 19° and 30° (example 24.5°).

On the other hand, if we have a greater need during the summer season it is good to have a tilt angle between 19° and 42° (for example 30°). If instead, we have a greater need during the winter season it is good to have a tilt angle between 42° and 65° (for example 53°).

#### Can Moonlight charge solar panels?

Electricity Generated by Your Solar Panels at Night Is Minimal. Seeing as moonlight is just sunlight reflected off of the moon, you will be happy to hear that the answer is yes: solar panels do technically work with moonlight.

### Why should solar panels face south?

South is best direction to maximize solar panel output – In the Northern Hemisphere, where the United States is located, solar panels will achieve maximum possible electricity production when they are facing south, That’s because, on average, the sun shines directly over the Equator over the year. Pictured: The furthest north the sun’s path travels is directly over the Tropic of Cancer, roughly 23.5° north of the Equator, during the summer solstice (June 21). As all of the mainland U.S. is located north of the Tropic of Cancer, the sun shines to the south for us all year-round.

Can You Put Solar Panels on a Flat Roof? Last updated on 26 September 2022 9 min read

• ✔ Solar panels can function on flat roofs
• ✔ But they’re more susceptible to water damage
• ✔ Fill in the form at the top of this page to receive quotes from trusted installers

Solar panels come in all shapes and sizes. On the market today, you can find traditional panels, flexible panels, and even solar tiles, making them suitable for all sorts of properties – even ones with flat roofs.

1. This particularly comes in handy for British homes, with our mix of new-build houses, old cottages, traditional farmhouses, and terraced homes.
2. But if you have a flat-roofed property and fancy getting yourself some panels, there are a few things you should know, including what extra equipment to get, how to look after your panels properly, and how to avoid damages.
3. Luckily, we’ll tell you everything you need to know further down the page.

If you’re already set on getting a solar panel system for your home, we can speed up the process for you. Rather than scouring the internet for the best companies and prices, simply answer a few short questions, We’ll pass your details on to our trusted suppliers, who will then get in touch with free quotes for you to compare, so you can cut your energy bills during this recession. Yes! Although flat roof solar panel systems are more commonly found on commercial buildings, they also work well on domestic properties. The solar panels that are used on a flat roof are exactly the same as the ones used on a pitched roof. You can technically lay the panels down on a flat roof – just as you would on a pitched roof – but this will restrict them from absorbing as much sun as possible, and might also lead to water damage.

1. That’s why you need to install a framing system, to tilt your panels towards the sun.
2. This will help them self-clean in the rain, and avoid damage from pooling water.
3. Yes, you can keep your home warm during the chillier months by installing solar thermal systems on a flat roof.
4. Similar to regular photovoltaic (PV) systems, can be attached to a flat roof with a mounting rack.

Getting solar panels for any property comes with its, but with a flat roof, you have a few extra things to think about.

• Flat roofs provide easy access for installation and maintenance
• Panels probably won’t be visible from the street
• You’ll be able to save money on electricity bills
• You’ll be able to shrink your carbon footprint
• They’re low maintenance
• Labour costs can be more affordable

While there are a number of disadvantages to flat roof solar panels, bear in mind that most of these can be resolved by using a tilted mounting system.

• Panels get far dirtier over time – On a tilted roof, rainwater usually washes dirt and debris off the panels. Without this self-cleaning feature, the dirt will stay there,
• Without additional mounting equipment, panels won’t get as much exposure – Solar panels usually face southward on a tilted roof, in order to increase sun exposure and create more energy. Laid flat, panels are unable to convert as much energy because they will not be getting as much sunlight
• Flat roof panels can make some warranties ineffective – When panels are laid flat, water sits between the frame and the glass coating of the module. Given this gap is only sealed with silicon, which easily degrades over time, panels are likely to become damaged faster than usual
• Wind effects are greater, which means your installer will need to be careful while designing the mounting system. Sometimes ballast weight is required, so you’ll need a structural engineer to check the roof can hold this extra weight.

On top of this, installation can come with a few added costs. To avoid the disadvantages above, many people invest in mounting systems. Generally, solar panel racking should make up roughly, although this will fluctuate depending on the brand and type of rack you get, along with the amount you need to buy.

To avoid water damage, it’s wise to invest in a mounting system that props your panels up. Roofs come in all shapes and sizes but, generally, panels will need to be mounted at a 20-50 degree angle to absorb as much sunlight as possible. And, as an added bonus, panels at this angle have a better chance of staying clean, as rainfall will remove debris and dirt that could reduce the panel’s efficiency.

Installers will often use specialist equipment to mount panels at the perfect angle, so make sure you contact a qualified professional to carry out your installation. Want to find trusted installers now? Get a head start by filling out – after answering a few questions about your property, our professional suppliers will be in touch with free quotes for you to compare.

• You usually need planning permission to install flat roof solar panels.
• Solar panels on pitched or tilted house roofs rarely require planning permission because they fall under the ‘permitted development’ category – but that’s not the case with flat roof solar panels.
• Since they aren’t classified as permitted developments, planning permission is more likely to be required.
• It’s therefore a good idea to The Planning Portal – the national planning application service for England and Wales.

Weather is an important thing to consider when it comes to solar panels – especially if they’re sitting on a flat roof. We’ve already mentioned how rain can damage panels on a flat roof, with water pooling causing the silicon to degrade, but thankfully this can be easily resolved with a mounting rack.

• Fixing panels to your home – This involves drilling into the roof itself and securing the brackets to keep the mounting frame stable. Take extra care to ensure the roof remains watertight
• Adding weight – If you’re unable to penetrate your roof, a good alternative is to simply add weight to the structure. The mounting frame can slot into concrete ballasts (heavy slabs) and make the panels much more wind-resistant. Get a structural engineer to check your roof can take this extra weight

Generally, installing solar panels on a flat roof will cost more than on a pitched roof – around 20% more, depending on the situation. Of course, prices vary depending on a range of factors, including the number of panels you get and which mounting technique you use.

The key reason flat roof solar panel installations are more expensive is the extra cost of materials for the framing system and ballast weight. You’ll also usually need to hire a structural engineer, which adds to the cost. The average three-bedroom house will save £522 per year with a 3.5 kWp solar PV system.

Our research into also shows that if you installed solar panels today, you’d break even in 10.4 years, and make an overall profit of £7,600 after 25 years. And with telling our latest National Home Energy Survey that they’d buy a house with solar panels, there’s every reason to go green.

Domestic renewable energy is becoming increasingly common across the UK, and as one of the most space-efficient ways to harness green energy, solar is leading the way. Plus, as we’ve discovered in this article, having a flat roof doesn’t have to be a barrier to installing solar panels at home. So, if you’d like to join the UK’s growing list of solar-powered homes, it’s time to start hunting for the perfect set of panels.

Luckily, we can help with that – all you have to do is pop your details in, Once we’ve got your information, we’ll pass it on to our trusted suppliers, who will then be in touch with free quotes for you to compare.

: Can You Put Solar Panels on a Flat Roof?

#### How do I aim my solar panels?

In a solar photovoltaic power system, each panel should ideally track the sun during the day to obtain the maximum possible energy. Unfortunately, this is often too expensive to implement, and most small solar power systems employ fixed panels. The question then becomes as to what direction the panels should be mounted.

Elevation Angle: The vertical tilt of your panels. Azimuth Angle: The horizontal orientation of your panels in relation to the equator.

unboundsolar.com unboundsolar.com unboundsolar.com Solar panels work best when they face directly into the sun. But that task is complicated by the fact that the sun moves across the sky throughout the day. It also changes the angle in the sky as the seasons change. So when you build a solar system, the question is: what’s the best angle to mount your solar panels to get the most output? unboundsolar.com Tilt and Azimuth angles are in relation to the Equator. Some people will want to set it at one angle and forget it, while others like to go hands-on with their system and make adjustments to optimize output. Optimal Azimuth Angle for Solar Panels For best results, your solar panels should face towards the equator.

If you live in Northern Hemisphere, face the south. If you live in the Southern Hemisphere, face them north. Specifically, you should point your panels toward true north as opposed to the reading on your compass, which is magnetic south. Many people are surprised to learn that their compass isn’t completely accurate.

That happens because magnetic forces in the Earth’s core pull the compass needle away from the true north or true south. Depending on your location, the compass reading can be inaccurate by as much as 25°! In the Northern Hemisphere:

If the magnetic declination is east (positive), rotate your panels east. If your magnetic declination is west (negative), rotate your panels west.

In the Southern Hemisphere:

Two examples to demonstrate the difference:

If you live in San Diego, California your magnetic declination is about 11° east. Since San Diego is in the Northern Hemisphere, start by finding the magnetic south, then adjust 11° to the east. In contrast: Cochran, Chile also has a magnetic declination of around 11° east. But since you are in the Southern Hemisphere, you want to point your panels north instead. So you would actually make an adjustment of 11° to the west to find the ideal azimuth.

India lies in the Northern Hemisphere

If you live in Hyderabad, Telangana, your magnetic declination is about 0.5° west. Hence, start by finding the magnetic south, and then adjust 0.5° to the west. If you live in Srinagar, Jammu, and Kashmir, your magnetic declination is about 0.3° east. Hence, start by finding the magnetic south, and then adjust 0.3° to the east.

By performing these adjustments, you will face your panels directly at the equator, maximizing their exposure to sunlight. Finding the Optimal Tilt for Your Solar Panels You have a couple of options here: pick one angle and leave it alone, or adjust the tilt a few times per year to optimize seasonal production.

• Optimal Tilt Angle (No Adjustments) If you never want to bother with adjusting your panels, set them at a tilt angle that is equal to your latitude.
• To use the above example again, San Diego is located at a latitude of 32.7157°N.
• You’d be just fine if you set your panels at around 33° and left them untouched.

One wrinkle to consider is changing the tilt slightly to favor summertime or wintertime output. If you spend more money in the summer running the AC, you might want to optimize for summer production. On the other hand, if you end up blasting the heat during harsh winters, you can set your panels to favor winter production.

This matters more for off-grid systems since you store your own power. If you are grid-tied, you most likely want to optimize for summer production, since the utility company will typically give you a credit for any over-production. You will produce more in the summer, and you can collect this credit in the winter months.

To optimize overall production year-round, tilt your panels at your latitude. To lean toward more production in the summer, tilt your panels at your latitude minus 10-15°. To lean toward more production in the winter, tilt your panels at your latitude plus 10-15°.

• Seasoned Adjustments to Optimal Tilt Angle If you have an adjustable mount and don’t mind tilting your panels manually, you can change the angle a few times a year to get a bit more production from your array.
• We should note that this isn’t a particularly common choice.
• Most of our customers simply give themselves a 5-10% cushion in production when sizing their system so they never need to make adjustments.

The main exception is in heavy snow areas. If snow will accumulate on your panels, pole mounts make a lot of sense. You can adjust them to a steeper tilt angle in the winter, which not only improves output but also sheds snow from the face of the panels.

If you are able to adjust the angle of your solar panels a few times a year, here is the adjustment schedule we recommend: Spring: Tilt the panels to your latitude. Summer: Tilt the panels to your latitude minus 15°. Fall: Tilt the panels to your latitude. Winter: Tilt the panels to your latitude plus 15°.

These are general guidelines, but you may get better results by customizing your adjustment schedule based on your location. For more info, read through solarpaneltilt.com an old-but-still-excellent reference that explains(in great detail) how to tilt your panels to maximize their production.

## How long do solar panels last?

Solar panels, also known as photovoltaic or PV panels, are made to last more than 25 years. In fact, many solar panels installed as early as the 1980s are still working at expected capacity. Not only are solar panels remarkably reliable, solar panel longevity has increased dramatically over the last 20 years.

#### Do solar panels need direct sunlight?

Mar.01, 2022 Solar panels work best in direct sunlight, but they can also work on cloudy days and in partial shade. This is because photovoltaic (PV) panels use particles of light, called photons, to generate electricity. Photons are present in direct and indirect sunlight, so solar panels can operate in both conditions.

#### How do you calculate the angle of tilt?

How to Calculate Solar Panel Tilt Angle When installing a solar lighting system or any system that take its power from the sun, the first question that comes to mind is what will be the direction of the solar panel and its angle, The solar panel will operate at peak efficiency when fully directed to the sun.

• So, which direction should we position the solar panel? When we look around, we can see solar panels that look at different directions from a different angle of inclination.
• This shows that there is a lack of information about which way the solar panel will look at, and how far it is inclined.
• It may seem a simple idea that direct the solar panel to the sun.

But we should keep in mind that the sun is located in different positions in different time zones during the year. During the day, the place is constantly changing. Therefore, it is necessary to calculate an optimal tilt angle, The direction of the solar panel is determined by the location where the system will be installed,

In countries like Turkey in the northern hemisphere, the solar panel is directed towards the south, In the countries located in the southern hemisphere, it is directed towards the north, Applications that we are used to seeing in our country (Turkey), where the solar panel is directed to the east or west are wrong.

In every city of our country, the solar panel should face to the south, When placed with an optimal tilt angle, the solar panel takes maximum solar power throughout the day. The angle of the solar panel depends on your location and at what time of the year you are.

However, this article will show calculations for the fixed solar panel angle that can be used throughout the year. So, once you set the angle of the solar panel, you’ll be able to use it all year round without touching the system. Solar panel tilt angle is calculated by the latitude value. This angle is multiplied by 0.87 if the latitude value is less than 25,

If the latitude value is between 25 and 50, it is multiplied by 0.87 and added 3.1 degrees to the result. Turkey is among the 36-42 degree latitudes, this calculation method should be used for all installations in our country. The ideal angle can be obtained at approximately 45 degrees if the latitude value is 50 degrees and above.

1. You can use the following formula to calculate the angle of inclination of solar panel for use in all cities in Turkey,
2. Solar Panel Tilt Angle = Latitude x 0,87 + 3,1 The angle of inclination to be found with the help of the calculation is the angle between the panel and the floor,
3. This means that the zero-degree panel inclination represents full horizontal positioning.90-degree panel inclination represents full vertical positioning.

Latitude value of your location can be easily found using, Select a point on the map, and Google will show you latitude and longitude, The first of the two numbers separated by commas is latitude, For example, let’s make a calculation for Ankara, The latitude and longitude value for Ankara is 39.911817, 32.809245,

The calculation can be done as follows.39,9 x 0,87 + 3,1 = 37,8 As a result of this calculation, it can be said that the solar panel should be directed to the north at 38 degrees angle for use throughout the year in Ankara position. The latitude and longitude value for Istanbul is 41.0082376, 28.9783589,

The calculation can be done as follows.41 x 0,87 + 3,1 = 38,8 In other words, the solar panel in Istanbul should have an inclination angle of 39 degrees, For Izmir it is 37, for Antalya 35 and for Trabzon it will be 39 degrees All of the above calculations were made according to the fixed panel tilt angle throughout the year.

1. You can use the solar panel at a fixed angle throughout the year.
2. Also, you can do separate calculations for summer and winter seasons and change the solar panel angle of inclination throughout the year.
3. There is a special reminder for the winter,
4. If there is snow in your area, you can prevent the accumulation of snow by increasing tilt angle of the solar panel.

By this way, you can take more advantage from the sun. Written by Emre Yılmaz –, Asya Traffic Inc. : How to Calculate Solar Panel Tilt Angle

#### What is the best location for solar panels?

The Best Location for Solar Panels Posted at 15:01h in by Solar panel location is an important thing to consider when in your home. Solar panels are typically installed in a fixed manner on the roof of your house and should be facing South, which receives the most sunlight.

• Solar panels generate more electricity when they get the most sunlight, which comes from the southern direction.
• There is a difference between the “magnetic south” and the “true south.” Solar panels should face the true south.
• A compass points to the magnetic south or the south pole.
• However, this isn’t exact, because the needle of the compass is pulled slightly away from true south because of the earth’s fluid metal outer core.

When your roof faces east or west and there is no way for the solar panels to face south, you can aim for more energy collection by using more solar panels. Another option is to mount the panels on a rack facing the south, although this option would entail more cost.

### Is a west facing roof OK for solar panels?

Which direction should my roof face for solar panels? – The best type of roof for solar panels is a south facing roof as they tend to generate the most electricity from solar panels. South facing roof panels see the sun when it is at its most intense for the longest period of time, which is why they generate the most energy.

However, this doesn’t mean that east or west facing roofs can’t also be suitable for solar panels. If your roof faces another direction as you can likely still see plenty of benefit from installing a solar array. East and west facing roofs are also suitable for solar panels and will still see a good deal of energy generation throughout the course of the day.

For example, an east facing roof will be exposed to sunlight in the morning whereas a west facing roof will take in more sunlight in the afternoon and evenings. Based on an installation of 8 panels at 3.5 meters in the LE16 postcode. As you can see, a south facing roof gives the optimal direction for solar panels, delivering a potential saving of £194.41 in the first year. Meanwhile a north facing roof would still save you money on your energy bills but not as much (£92.35).

### Does it matter if solar panels are vertical or horizontal?

Does It Matter If Solar Panels Are Horizontal Or Vertical? When you take the plunge and decide to have solar panels installed on your roof, it’s a big decision! Of course you want to be sure that everything is done the right way and that you’re going to be happy with the way your house looks with the system.

• You’ve probably seen some solar systems where the panels are installed in vertical orientation, and others in a horizontal orientation.
• This might leave you wondering, why are they different and does it matter if solar panels are horizontal or vertical? The orientation of your solar panels doesn’t affect the production of your system.

In the US, panels are generally installed vertically by default unless you have a flat roof which better allows for horizontal panels since they won’t protrude as much. Let’s dive a little deeper to think about why your solar panel orientation may have been chosen for your home, and why other systems have their own design.

### How do I aim my solar panels?

In a solar photovoltaic power system, each panel should ideally track the sun during the day to obtain the maximum possible energy. Unfortunately, this is often too expensive to implement, and most small solar power systems employ fixed panels. The question then becomes as to what direction the panels should be mounted.

Elevation Angle: The vertical tilt of your panels. Azimuth Angle: The horizontal orientation of your panels in relation to the equator.

unboundsolar.com unboundsolar.com unboundsolar.com Solar panels work best when they face directly into the sun. But that task is complicated by the fact that the sun moves across the sky throughout the day. It also changes the angle in the sky as the seasons change. So when you build a solar system, the question is: what’s the best angle to mount your solar panels to get the most output? unboundsolar.com Tilt and Azimuth angles are in relation to the Equator. Some people will want to set it at one angle and forget it, while others like to go hands-on with their system and make adjustments to optimize output. Optimal Azimuth Angle for Solar Panels For best results, your solar panels should face towards the equator.

• If you live in Northern Hemisphere, face the south.
• If you live in the Southern Hemisphere, face them north.
• Specifically, you should point your panels toward true north as opposed to the reading on your compass, which is magnetic south.
• Many people are surprised to learn that their compass isn’t completely accurate.

That happens because magnetic forces in the Earth’s core pull the compass needle away from the true north or true south. Depending on your location, the compass reading can be inaccurate by as much as 25°! In the Northern Hemisphere:

If the magnetic declination is east (positive), rotate your panels east. If your magnetic declination is west (negative), rotate your panels west.

In the Southern Hemisphere:

Two examples to demonstrate the difference:

If you live in San Diego, California your magnetic declination is about 11° east. Since San Diego is in the Northern Hemisphere, start by finding the magnetic south, then adjust 11° to the east. In contrast: Cochran, Chile also has a magnetic declination of around 11° east. But since you are in the Southern Hemisphere, you want to point your panels north instead. So you would actually make an adjustment of 11° to the west to find the ideal azimuth.

India lies in the Northern Hemisphere

If you live in Hyderabad, Telangana, your magnetic declination is about 0.5° west. Hence, start by finding the magnetic south, and then adjust 0.5° to the west. If you live in Srinagar, Jammu, and Kashmir, your magnetic declination is about 0.3° east. Hence, start by finding the magnetic south, and then adjust 0.3° to the east.

By performing these adjustments, you will face your panels directly at the equator, maximizing their exposure to sunlight. Finding the Optimal Tilt for Your Solar Panels You have a couple of options here: pick one angle and leave it alone, or adjust the tilt a few times per year to optimize seasonal production.

Depending on your preference, here’s our advice. Optimal Tilt Angle (No Adjustments) If you never want to bother with adjusting your panels, set them at a tilt angle that is equal to your latitude. To use the above example again, San Diego is located at a latitude of 32.7157°N. You’d be just fine if you set your panels at around 33° and left them untouched.

One wrinkle to consider is changing the tilt slightly to favor summertime or wintertime output. If you spend more money in the summer running the AC, you might want to optimize for summer production. On the other hand, if you end up blasting the heat during harsh winters, you can set your panels to favor winter production.

This matters more for off-grid systems since you store your own power. If you are grid-tied, you most likely want to optimize for summer production, since the utility company will typically give you a credit for any over-production. You will produce more in the summer, and you can collect this credit in the winter months.

To optimize overall production year-round, tilt your panels at your latitude. To lean toward more production in the summer, tilt your panels at your latitude minus 10-15°. To lean toward more production in the winter, tilt your panels at your latitude plus 10-15°.

Seasoned Adjustments to Optimal Tilt Angle If you have an adjustable mount and don’t mind tilting your panels manually, you can change the angle a few times a year to get a bit more production from your array. We should note that this isn’t a particularly common choice. Most of our customers simply give themselves a 5-10% cushion in production when sizing their system so they never need to make adjustments.

The main exception is in heavy snow areas. If snow will accumulate on your panels, pole mounts make a lot of sense. You can adjust them to a steeper tilt angle in the winter, which not only improves output but also sheds snow from the face of the panels.

If you are able to adjust the angle of your solar panels a few times a year, here is the adjustment schedule we recommend: Spring: Tilt the panels to your latitude. Summer: Tilt the panels to your latitude minus 15°. Fall: Tilt the panels to your latitude. Winter: Tilt the panels to your latitude plus 15°.

These are general guidelines, but you may get better results by customizing your adjustment schedule based on your location. For more info, read through solarpaneltilt.com an old-but-still-excellent reference that explains(in great detail) how to tilt your panels to maximize their production.

Let’s dive a little deeper to think about why your solar panel orientation may have been chosen for your home, and why other systems have their own design.

#### Which direction must solar panels face?

The general notion is that North-facing solar panels (in the Southern Hemisphere) is the most effective way of mounting solar panels. Have you ever considered mounting your panels East & West? Source: solarquotes.com.au Roof orientation The direction of your panels in relation to the sun, also referred to as the Azimuth angle, is important for the amount of sunshine that your solar panels will receive over the course of the day. The best way to determine the direction that your roof faces is to use Google Maps. Picture: Tropic of Capricorn, source: Wikipedia This means that the general idea for positioning panels is when you face your panels to the North, you will receive the most sunshine. The Sun’s movements in a day The sun rises in the East and sets in the West.

So that means in the mornings you will have more sunlight from the East, and in the afternoon you will have more sunlight from the West. Energy usage When your household is out for most of the day, and don’t use a lot of energy during the day, East-West might be an option. You will have solar yield in the morning when you use energy for your lights, hot water, breakfast etcetera, and when you come back in the evening you will use lights, TV etc.

The East facing panels will make sure your battery will be fuller earlier in the morning, and the West facing panels will make sure you battery is full when you come home. So your panels will generate more electricity when there is a high demand. Over a whole day, solar panels that are oriented directly East or directly West will only produce roughly 10 percent less electricity than if they were facing due North.

1. However, considering what has been said before, this might be a better option for you.
2. Ground / flat roof mounting East-West orientation of the panels when they are ground-mounted or on a flat roof, means that shallower angles can be used (e.g.5–10°).
3. Shallower panels means more panels can be mounted in a given space, as there are less shading issues between the panels and panels can be mounted closer together.

The shallower angle is also cheaper to install, as less mounting material is required. Electricity tariffs In the future, if you have to pay more for electricity in the period of high demand, e.g. in the morning or afternoon, it also makes sense to generate more electricity during those peaks, to save costs or to get a better rate once you can sell back to the grid.

Make sure there is as little shading as possible on your panels Angle of your panels (25-35° for North-facing) Use different charge controllers for different orientations Mount a similar number of panels East and West
