On-Grid solar systems can actually reduce your monthly electricity bill! Since on-grid systems are incorporated with main grid supply, the power generated using solar energy during the day can be used and consumed by powering appliances and devices in homes as per the need. The excess solar electricity produced can be fed to the grid. During night hours or cloud cover, the power can be drawn from the grid.
The grid-tied solar systems work on net-metering technology. In such systems, a bi-directional electricity meter installed in your homes or residential complexes records the power used, excess power exported to the grid and power imported from the grid.
If the electricity import from the grid, besides your power consumption from the solar electricity is more, you pay to the electricity board. But if the export of your solar power to the grid exceeds at the month-end, the board pays you the compensation.
The on-grid solar systems allow to use grid supply when the solar power is not able to generate required electricity – during night or cloud cover. Otherwise, you can easily consume power without using grid supply and thus cut down on your electricity expenses.
Interestingly, this system can not only help you reduce your electricity bill but can help you earn money.
