Solar On-Grid Electric System
How does a grid-connected solar electric system work?
By on grid we mean that the solar electric system is connected to the Electricity Board power lines. The working of an on grid solar electric system is very simple.
Broken down into its component parts the steps are:
- Whenever the sun shines (even in overcast weather) and the sunshine fall on the panels the solar cells generate DC electricity.
- The grid connected inverter converts the DC electricity produced by the solar panels into 240V, 50 HZ AC electricity, which can then be used by the household, to power the appliances.
- If the grid connected system is producing more power than is being consumed, the surplus is fed back into the Electricity Board’s main grid. The Board will meter the electricity fed into the grid by your system and provide a credit on your bill.
- When the solar cells are not producing power, for example at night, your power is supplied by the Board’s power grid as usual. The electricity board charges the usual rate for the power used.
Solar Hybrid Electric System
We can also create a hybrid solar electric system. It is an on-grid solar system with an extra battery storage added. Since there is an added battery component the cost will be higher than the on-grid system, but the benefits are also higher.
This system combines the best of the on-grid and off-grid solar electric systems. While you can continue selling electricity generated to the grid in times of surplus you can also store and use it during those times when there are problems in supply and regular blackouts.
