Patent attributes
A method for installing a photovoltaic system is presented and may involve receiving an identity of a building, and accessing a data store to obtain physical characteristics of the building based on an address of the building. The method may also include accessing a second data store to obtain weather information for a geographic region that includes the building, determining an available installation area to install a photovoltaic system on the building based on the physical characteristics of the building, and calculating an installation area for the photovoltaic system based at least in part on the weather information and the available installation area to maximize average efficiency of photovoltaic cells within the photovoltaic system. Further, the method may include adjusting the size of the PV system based on a building specific non-energy based constraint.
