Solar panel spec.: Grid Connected Photovoltaics In order to use energy at night or on cloudy days, some form of storage is necessary. Where utility power is available, the building can generate power into the grid and actually allow the electric meter to run backwards and earn a credit for the owner. When the sun doesnt shine, the meter would then wind normally. The benefit to the owner is reduced electric costs and elimination of the need for expensive and bulky storage batteries because the grid acts as the storage system. The power company actually benefits as well. During the peak demand periods their generating capacity is being supplemented by their solar customers. Also the grid is less stressed by having generation spread out along it instead of having all the generation concentrated at one end.
