What Is On Grid Solar System?

What Is On Grid Solar System
On-grid means your solar system is tied to your local utility’s GRID. This is what most residential homes will use because you are covered if your solar system under or over-produces in regard to your varying energy needs. All this means for you is that your utility system acts as your battery space.

What is meant by off-grid and on grid solar system?

Major Differences between On-Grid and Off-Grid Solar System Installing a solar power system can be a daunting task, especially for a customer who has to make many decisions such as choosing the right solar panels, estimating the power consumption, opting between an off grid solar power system and on grid solar system and more.

  1. Although all solar power systems work on the photovoltaic (PV) effect, how the energy generated by solar devices is to be utilised depends on the user.
  2. For instance, if you wish to use solar energy independent of the grid network, you can opt for an off grid solar system,
  3. Alternatively, if your energy output is more than what you consume, then an on grid solar power system can help you to redirect any surplus energy to the grid via net metering.

Sounds complicated? Actually, the difference between on grid and off grid solar system is quite simple. As the name suggests, an off grid solar system is not connected to the grid, while an on grid solar system is networked to the utility grid. A customer’s choice of a particular grid system influences the equipment needed for the installation, installation method as well as energy bills.

What is the advantage of on grid solar system?

Skip to content admin 2022-08-26T08:17:43+00:00 Net-meter is a device that records the energy supplied to the grid and the energy drawn from it. At the end of each month, the net energy consumed is recorded and the consumer is provided with a bill. This feature makes the on-grid solar system a great investment with high returns.

  • Benefits of on-grid solar 1.
  • Huge reduction in electricity bills With net-meter in place, the consumer has to pay only for the surplus electricity he consumes, ensuring the bill generated every month is reduced drastically.
  • Many of our customers have been able to reduce their monthly bills by 90%.2.
  • Easy maintenance The elimination of batteries in the on-grid system makes the maintenance quite easy.

It also eliminates the cost of upkeep of the batteries 3. Synchronize with other sources of power These systems can also synchronize with a diesel generator on site. This is important in case grid power is not available. (We should add a link here to connect with another blog or technical article to learn more about this) 4.

  • Better ROI Cost of a On-grid solar system is lower than other types of solar systems because there are no batteries.
  • It also generates the highest amount of power compared to other types of solar systems.
  • The minimal maintenance and reduction in monthly power bills ensure the customer gets an ROI of 25 – 30%.

This means the customer earns Rs.25,000 for every 1,00,000 they invest in solar. With these advantages, an on-grid system is best suited for a customer with stable grid power and minimal power cuts. Other than homes, even educational institutions, industrial units, commercial establishments install an on-grid system as the system can synchronize with diesel generators to provide uninterrupted power.

What is the disadvantage of on grid solar system?

Disadvantages of on-grid systems –

  • On-grid solar systems are battery-less and therefore not able to function or generate electricity during a blackout, due to safety reasons. As blackouts usually occur when the electricity grid is damaged – if the solar inverter was still feeding electricity into a damaged grid it would risk the safety of the people repairing the fault/s in the network.
  • They can’t produce solar energy and reduce your power bill at night-time or when there’s no sunlight.
  • They provide you with less incentive to conserve energy!

Does On grid solar system work without electricity?

To make the right choice it is important to comprehend the key differences between off-grid and on-grid solar systems. – What Is On Grid Solar System Team ProductLine With the increasing costs of power and electricity, a number of businesses are shifting to solar power systems. The Ministry of New and Renewable Energy (MNRE), Government of India is also encouraging solar PV systems for businesses under its Jawaharlal Nehru National Solar Mission.

India is ranked second among emerging economies to lead towards a transition to clean energy, according to a 2018 report by Climatescope. Commercial and industrial buildings in India, which are supplied grid electricity at significantly higher rates than residential users, find switching to solar systems more economical.

While making a decision to shift to solar power systems a number of businesses get confused between off-grid and on-grid solar systems. To make the right choice it is important to comprehend the key differences between off-grid and on-grid solar systems.

  • On-grid solar systems On-grid solar power systems generate power using a solar power system and are directly connected to the utility power grid.
  • These systems send excess power generated by the solar power system to the utility grid and consumers get compensated for the extra power fed back.
  • These systems work in collaboration with the power grid.

In the case when there is not enough sunlight to meet your business’ needs, the system runs on the power supplied by the grid. These systems are best suitable when your power consumption is high and you wish to reduce your electricity bills. On-grid systems can be installed with or without net metering.

Being connected to the main grid, these systems do not work during power outages. Applications: Businesses can rely on on-grid solar systems to meet their daily requirements, as well as earn income from the excess power generated. On bright sunny days, buildings can generate enough solar energy to power appliances, lights, water heating systems, etc.


On-grid solar systems are very cost-effective and easy to install. Businesses can recoup the cost of their investment by offsetting electricity bills in just 3-8 years. If a private, commercial or industrial building sets up a solar PV rooftop system it will be eligible to avail an ‘Accelerated Depreciation Benefit’ which is currently 80% in a year. At this rate, a business can completely depreciate the whole value of the project in approximately 4 years. Residential users and business owners can earn a passive income for the surplus energy generated by the system.

Off-grid Solar systems Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structure and balance of systems.

The panels store enough sunlight during the day and use the excess power generated in the night. These systems are self-sustaining and can provide power for critical loads in areas where a power grid is not available. However, these systems require specialized equipment to function and can be costly to install.

These are ideal for businesses which can sustain for a short period of time with no electricity. Applications

Electricity supply in rural and remote areas – Off-grid solar systems can facilitate independent, long-term and sustainable electricity generation in rural and remote areas. Power back up in areas with frequent electricity cuts – A number of places in India face frequent power cuts due to power transmission malfunctions, which can hamper operations of companies and public institutions. Off-grid solar systems can provide an economical and viable long-term backup solution to overcome the problems occurring during frequent power cuts.


These self-sustainable systems can work independently and do not rely on the grid. They generate enough power that can be stored and used at night or when the power grid is down. These are ideal for remote areas where there is no power access from the grid. Grid failures and shutdowns will not affect your power supply.

Electricity consumption in India is forecasted to reach 15280 TWh by 2040. The Indian government has set a target of reaching a renewable energy generation capacity of 225 GW by 2022 and is offering a number of benefits as well as tax rebates to businesses which shift to renewable solar energy systems.

  1. Solar power systems are a source of clean renewable energy and have numerous benefits depending on the type of system you choose.
  2. Due to a drop in the prices of solar PV in the last few years as well as significant policy-level implementations by the Government of India, setting up solar PV technology systems in residential buildings and business organizations have become very lucrative.

Why would anyone want to build a grid connected system?

When connecting a home energy system to the electric grid, research and consider equipment required as well as your power provider’s requirements and agreements. | Photo courtesy of Solar Design Associates, Inc. While renewable energy systems are capable of powering houses and small businesses without any connection to the electricity grid, many people prefer the advantages that grid-connection offers.

  • A grid-connected system allows you to power your home or small business with renewable energy during those periods (daily as well as seasonally) when the sun is shining, the water is running, or the wind is blowing.
  • Any excess electricity you produce is fed back into the grid.
  • When renewable resources are unavailable, electricity from the grid supplies your needs, eliminating the expense of electricity storage devices like batteries.

In addition, power providers (i.e., electric utilities) in most states allow net metering, an arrangement where the excess electricity generated by grid-connected renewable energy systems “turns back” your electricity meter as it is fed back into the grid.

What is the difference between off-grid and hybrid inverter?

Advantages and disadvantages of hybrid inverter& Off-grid solar inverter – The main advantage of a hybrid inverter is that the excess power can draw from the grid when the solar power produced is not sufficient to run the load. In addition to that the storage batteries provide backup in case of grid failure.

Therefore hybrid inverters provide a constant power supply and you need not worry about power outages. The battery system connected to the hybrid inverter allows maximum utilization of plentiful solar radiation on sunny days. Hence, it ensures optimal utilization of renewable resources. A hybrid inverter does not require frequent servicing and it has a low maintenance system.

The major concern is that adding a hybrid inverter into the existing solar system demands a complete and costly re-work of the entire solar panel system. Hence, hybrid inverters are not an ideal option for upgrading an existing system. Moreover, the initial installation expense of a hybrid inverter is very high compared to the other solar power inverters.
