Solar panels are made of photovoltaic (PV) cells, which turn sunlight into electricity.
Solar panels are an environment friendly way of producing electricity for your Home, Industry and any electrical appliances. Nothing will change, except that you'll pay less for your bills. You can stay with your existing energy supplier, who will take readings from your meter as normal and bill you as usual. Any electricity genrated by Solar which is not used will be sent to the grid.
