Your panels generate power that you consume directly using devices and appliances, all through the day. If your usage is conservative, the excess unused power simply gets fed back into the power grid, adding credits to your electricity bill to offset your payment to the Board.
At night, when the panels are dormant sans sunlight, you consume power off the grid as always, like any other consumer.
These systems are ideal for residential properties, community and public buildings, businesses and schools since they offer the security or backup of still being connected to the power grid.
NET METERING
Net-metering which will be provided by the TANGEDCO is a billing mechanism that credits solar energy system owners for the surplus electricity they add to the grid, over and above what they consume for themselves.
Take for example, if a residential customer has a solar rooftop, it may generate more electricity than the home uses during daylight hours. If the home is net-metered, the electricity meter will run in reverse to provide a credit against what electricity is consumed at night or other periods where the home’s electricity use exceeds the system’s output. Customers are only billed for their “NET” energy use. During the day, most solar customers produce more electricity than they consume. Net metering allows them to export that power to the grid and reduce their future electric bills.
