Solar Panels For Homes

Do most solar photovoltaic systems, which are connected to the grid have no batteries?

Batteries are expensive and most systems today, are sized based on your electric bill for a year, how much irradiance your area gets per year, averaged to per day. They systems people buy are designed that the power company (who often pays part of the cost of your installation) buys your excess power when you are out shopping, working and school in sunny times. They credit your account and supply your power at night and bad weather. Few people get batter back-up. Only people in the back woods away from power lines have the old style, battery based solar PV today. Most are tied seamlessly to the electric grid and sized so that the power you generate, the size of your PV system and the power you get from the power company at night and bad weather is offset by the power they buy from you when you are not using all the power your system generates. Works great. People with horses and buggies resisted cars at first too
