An ongrid solar panel system
An On-grid solar system (also known as a grid-tied solar system) in India is a type of solar power system that is connected to the local electricity grid. This system generates electricity using solar panels during the day and sends any excess power produced back into the grid, allowing the user to receive credits or compensation for the excess energy supplied.
Key Features of an On-grid Solar System:
Connection to the Grid:
The system is connected to the local electricity grid, which means it does not have batteries to store excess energy. Instead, any extra power produced during the day is sent back to the grid.
Net Metering:
India’s Net Metering policy allows users to receive credits for the surplus energy they export to the grid. This credit can then be used to offset the electricity consumed from the grid during periods when the solar system isn't generating power (e.g., at night).
No Battery Storage:
On-grid systems do not require batteries for storage. All energy generated is either consumed by the household or exported to the grid. This makes on-grid systems simpler and cheaper to install compared to off-grid systems.
Cost-Effective:
Since there is no need for battery storage, the installation cost of an on-grid system is generally lower than that of an off-grid system. Moreover, users can save significantly on electricity bills by using solar energy during the day and drawing from the grid during the night.
Energy Exchange:
The system typically operates during daylight hours when sunlight is abundant. During this time, the solar panels generate electricity. The energy generated is used by the household, and any surplus is sent to the grid. At night, when solar generation is not possible, the household draws electricity from the grid, which can be offset by the credits earned during the day.
Environmentally Friendly:
On-grid solar systems help reduce the carbon footprint by decreasing reliance on fossil fuels for electricity generation. This contributes to India’s renewable energy goals and the global push for clean energy.
How Does an On-grid Solar System Work?
Solar Panels: The solar panels installed on the roof of the house or building capture sunlight and convert it into direct current (DC) electricity.
Inverter: The DC electricity is then passed through an inverter, which converts it into alternating current (AC) electricity, which can be used in the household.
Grid Connection: Any excess power generated by the solar system is sent back to the electricity grid, while the home draws electricity from the grid when the solar system is not generating enough energy (like at night).
Benefits of On-grid Solar Systems:
Lower Electricity Bills: By generating solar energy during the day and utilizing the grid for any additional needs, households can significantly lower their electricity bills.
No Maintenance of Batteries: Since the system does not require batteries, there is no maintenance cost or concern for battery replacement.
Sustainable Energy: It helps reduce the dependency on conventional energy sources, promoting the use of renewable energy.
Incentives and Subsidies: The government offers subsidies and incentives for installing solar systems, making the adoption of on-grid systems more affordable.
Challenges:
Dependence on the Grid: On-grid systems do not function during power outages unless there is a special provision for backup power.
Solar Generation Only During the Day: Since the system generates electricity only when sunlight is available, electricity needs at night have to be met through the grid unless the system is designed with battery backup.
Conclusion:
An on-grid solar system is a great option for homeowners and businesses looking to reduce their electricity bills and contribute to clean energy generation. With government subsidies and net metering policies in India, this system offers an efficient and cost-effective way to utilize solar energy.
