How does the solar system work?
1. Whenever the sun shines (and even in overcast weather), the solar cells generate electricity using photovoltaic (PV) technology.
2. The grid connects inverter converts the DC electricity produced by the solar panels into 240V AC electricity, which can then be used to power appliances to your home.
3. If a grid connects system is producing more power than the home consumes, excess electricity will be stored in the battery (if you have installed it) which can be used at night time so you don’t need to buy electricity from the grid. This is the best way to save money on the power bill.
4. If you haven’t installed a battery, then the excess electricity generation makes its way back to the Grid, and you are paid for this electricity So no power is wasted. The rate you are receiving for the electricity export depends upon whom your energy retailer is.
When the solar cells are not producing power, for example at night, power comes from the mains power grid as usual. The energy retailer charges the usual rate for the power used.
