Most solar systems installed today are what is called 'grid-tied' and don't use batteries. The solar panels on your roof convert the sun into electricity which is either used immediately in your house by lights, appliances, etc. or spins your meter backwards and is 'sold' back to the utility. This extra power is most likely used by your neighbors so they can thank you for installing a solar system!
