Can I install my own solar system?
Solar installations are getting easier all the time and there’s plenty of do-it-yourself information out there. But are you ready to go the DIY route? – Photo © Heshphoto, inc., excerpted from Install Your Own Solar Panels, If you’re interested in solar power, surely you already know that solar electricity is good for the environment, national security, and the air we breathe, not to mention your electricity bill.
And that it’s one of the best ways to reduce your household’s contribution to global warming. You’ve also probably heard that going solar can actually be cheaper than paying for utility power, and you might wonder whether this claim is true. Well, in most cases, it is true. It just takes time for the incremental savings to overtake the initial investment (after that, the solar power is free).
If you install the solar system yourself, you can hit this tipping point a lot sooner — in some cases, in half the time. That brings us to the next big question: Can you really install your own solar panels? Again, the answer is yes. If you can drive lag bolts and assemble prefabricated parts, and if you’re willing to spend a day or two on your roof (or not, if you’re mounting your panels on the ground), you can install your own solar system.
You don’t have to know how to hook up the solar panels to your household electricity or the utility grid. You’ll hire an electrician for the house hookup, and the utility company will take care of the rest, usually for free. For a completely off-grid system, the utility company isn’t involved at all. Perhaps disappointingly, this job isn’t even a good excuse to buy new power tools, since the only one you need is a good drill.
So, if this is such a doable project, why do most people use professional installers? For starters, a lot of people have good reasons to hire out virtually everything, from oil changes to grocery shopping. (That’s probably not you, but even if it is, our book can help you plan for a solar installation and find a good local installer.) Solar professionals handle more than the installation.
- They design the system, they apply for rebates and credits, they order all the necessary parts, and they obtain the permits and pass all the inspections.
- But the fact is, you can do all of these things yourself, provided you have a helpful adviser and you are willing to follow the rules of the local building authority (that’s where you’ll get those permits).
Solar installations are getting easier all the time, and you might be surprised at how much do-it-yourself (DIY) help is available. Two good examples are PVWatts and the Database of State Incentives for Renewables & Efficiency (DSIRE), PVWatts is an online calculator that helps you size a solar-electric system based on the location and position of your house and the angle of your roof.
- Solar pros use the same simple tool, but it’s free for everyone.
- DSIRE offers an up-to-date, comprehensive listing of renewable energy rebates, tax breaks, and other financial incentives available in any area of the United States.
- And it’s also free and easy to use.
- Those two resources alone help answer the two most common questions homeowners have about solar electricity: How big of a system do I need? and How much will it cost? Other resources include solar equipment suppliers that cater to DIYers and offer purchasing and technical support, as well as online communities like Build It Solar,
And there’s no law that says DIYers can’t hire a solar professional for help with specific aspects of their project, such as creating design specifications, choosing equipment, or preparing permit documents. We should also say up front that installing your own solar panels is not a process well-served by cutting corners.
We don’t want you to install your system without a permit or without hiring an electrician to make the final hookups. (Even professional solar installers use electricians for this stuff.) The permit process can be a pain, yes, but it’s there to ensure that your system is safe, not just for you but also for emergency responders who might need to work around your mini power plant.
When you work with the local building department you also learn about critical design factors, such as wind and snow loads, that are specific to your area. Photo © Heshphoto, inc., excerpted from Install Your Own Solar Panels,
How much solar energy is needed to power a home?
The average American home needs between 16 and 20 solar panels based on the average electricity usage of 893 kilowatt-hours (kWh) per month. Installing that many solar panels would cost between $12,000 and $17,000 after the federal solar tax credit, However, chances are your energy usage doesn’t line up exactly with the U.S.
What are the 3 types of solar panels?
Solar Panel Cell Count and Efficiency – All PV panels differ in efficiency. Meaning certain types and even brands of Solar panels can convert sunlight into electricity more effectively than others. This is because panels can vary in the number of silicon cells and type they have.
The cell count of a Solar Panel often determines its cost, size and weight. Although it is often believed the more silicon cells a panel has, the high wattage and power output it will produce, this isn’t always the case. The power output of a panel is dependant on the quality and efficiency of the solar cells themselves.
Do It Yourself Solar Power? – Easy DIY Solar Panel Installation!
In this blog we will explore the main three types of solar panel cells: polycrystalline, monocrystalline and thin-film. Understanding the difference between the three, is the very first step to selecting your perfect panel for your home, business or community.
Can you run a house entirely on solar?
Why is solar power important? – In the last few decades, we have all become a lot more conscious of environmental issues and the need to reduce our carbon footprint. Knowing that solar panels can power a house, even if in tandem with more traditional methods, meets not only those renewable energy efficiency goals, but is also a great way to be financially savvy.
Solar panels can power a house in terms of powering the daily devices we have come to depend on, and all that energy adds up. After making the initial investment in solar panels, you’ll see the financial benefits within a short space of time due to the reduction of your energy bills. What’s more, it’s even possible to get full payback on your investment if you’re smart about your energy consumption levels.
In order to get the most out of your home solar panel system, you’ll have to be aware that they come in all shapes, sizes, build qualities, and power outputs. To speak to a member of our informative team about your solar power options, get in touch today.
Does solar power work in winter?
Solar panels work through all four seasons of the year, come rain or shine, or even hail or in light snow. But solar panels do generally produce less energy in winter. That’s because the days are shorter, so there are fewer hours of daylight and the sun is lower in the sky, on average.
How many appliances can I run on solar?
How long do you need power for? – A battery’s size determines how long your appliances can run for. When we talk about battery size, we’re referring to how much electricity the battery can hold, in kilowatt-hours (kWh), for your home to use. This is most commonly called the ‘usable capacity’ of the battery,
The average refrigerator for 14 hours A television for 130 hours An LED light bulb for 1,000 hours A WiFi router for 2,000 hours
However, it’s unlikely that you want to back up just one appliance in the event of a power outage. That means if you want to power more appliances, you won’t be able to run your fridge for a full 14 hours, because another load will be using the energy stored in your battery at the same time.
| Essential load | Wattage | Hours | kWh consumed |
|---|---|---|---|
| Refrigerator | 700 W | 8 | 5.6 kWh |
| Lights | 400 W | 5 | 2.0 kWh |
| Electric stove | 2,500 W | 0.5 | 1.25 kWh |
| Microwave | 900 W | 0.25 | 0.23 kWh |
| Laptop charger | 61 W | 2 | 0.12 kWh |
| Phone charger | 20 W | 4 | 0.80 kWh |
| Television | 77 W | 2 | 0.15 kWh |
| WiFi router | 5 W | 8 | 0.4 kWh |
| Total kWh needed | 9.47 kWh |
In this example, a 10 kWh battery would be able to run your most important loads, like the fridge and WiFi router for 8 hours, and still let you use your other appliances before it needs to be recharged. If you installed a 15 kWh battery, you could potentially run more loads than the ones we listed in this example. Or you could run the same loads for a longer period of time instead.
How many solar panels are needed for a 4 bedroom house?
How many solar panels are needed for a house? – The average one-bedroom house needs six solar panels, a typical three-bedroom house requires 10 panels, and a five-bedroom house will usually need 14 panels. Want to see how much this would cost you? Head to our solar panel cost page.
| Household Size | Annual Electricity Usage | Number of Solar Panels | Size of Solar Panel System |
|---|---|---|---|
| 1 bedroom | 1,800 kWh | 6 | 2.1 kW |
| 3 bedrooms | 2,900 kWh | 10 | 3.5 kW |
| 5 bedrooms | 4,300 kWh | 14 | 4.9 kW |
In each case, the panels will produce enough electricity to cover around 50% of a household’s annual usage – or more, if you don’t leave the house very often. Without a solar battery, around half of this energy will go unused by your home, because you won’t always be there to use it when it’s generated.
Which solar panel is best?
6. Vikram Solar ELDORA polycrystalline modules –

Is it cheaper to install solar panels yourself?
Pro: Cost savings – A DIY solar panel installation can save homeowners thousands of dollars in upfront installation costs. The average cost of solar panel installation by a professional solar company is around $2.95 per watt, For a typical 5 kW (5,000 watt) solar panel system, that works out to $14,750.
- On the other hand, a 5 kW DIY solar panel kit costs between $1.00–$1.50 per watt.
- Assuming you perform the entire job by yourself (i.e.
- No contractors for any of the tasks), the total cost of a 5 kW DIY solar project is between $5,000 and $7,500.
- That works out to a potential savings of $7,250 – $9,759 by choosing DIY over a professional solar installation.
The figures above are just averages. There are many variables that can change these numbers for you, such as system size and whether or not you qualify for the solar tax credit (worth 30% of solar energy system costs ).
How much does it cost to install your own solar panels?
3. Estimate and compare residential solar panel costs – The brunt of the expense with solar panels is in installation and the purchase of the actual panels. Minimal long-term costs can make up for the upfront costs. “Most systems don’t require much maintenance and are designed to last for 20 years or more with little change to the amount of electricity produced,” Nilsen says.
- When calculating the total price, consider how much energy you regularly consume — your usage is listed on your monthly utility bill — and what size system will generate the amount needed.
- Some tools, like the SolarReviews calculator, estimate the system size for you.
- With installation, an average residential 5-kW system costs from $3 to $5 per watt, according to the CSE, which results in the $15,000 to $25,000 range.
That cost is before any tax credits or incentives. If you know your current energy usage, you can calculate how much you’ll need to pay for solar panels. Then comparison shop for solar panels as you would other big-ticket items, such as a car or TV, says Vikram Aggarwal, CEO of the solar marketplace EnergySage.
How much does it cost to buy your own solar system?
How Much Do Solar Panels Cost? – Switching to solar energy requires an up-front investment in equipment and installation. But after that initial cost, the only recurring charge is the electricity you use beyond the power your panels generate. Assuming your solar system is the right size for your home and is properly installed and maintained, homeowners typically see long-term savings on electricity bills and a return on their investment after several years.
The SEIA estimates the national average cost of a residential solar panel system is $2.94 per watt.* That translates to just under $11,000 for a 5 kW system, the average size of a standard residential solar system in the United States. The price of solar panels varies by brand and retailer. Keep in mind that solar panels are only a fraction of the total cost of going solar.
Installation (including supporting equipment) and ongoing maintenance make up the remaining expenses. The table below gives an overview of solar panel costs by state to give you a general starting point for pricing. For comparison, the Energy Information Administration breaks down electricity prices by state for 2020 and 2021.
Is it worth building your own solar panel?
Ultimately, Is It Cheaper To Build or Buy Solar Panels? – A DIY solution should cost you less upfront than having a system installed. However, if you build the panels yourself, it may cost you more in the long run. The materials may not be very efficient and may not last as long. Also, you may need to absorb the cost of replacing them without a manufacturer’s warranty to back them up.
