Capacity estimator for an energy generation and/or storage system

Apparatus for estimating capacity of a system including an energy generation system, an energy storage system, or both comprising:

• one or more processors coupled to one or more non-transitory computer readable media storing instructions thereon which, when executed by the one or more processors, cause the one or more processors to perform the operations comprising:
• receiving indicium of a location for installation of the system;
• receiving indicium of facility size;
• determining an initial estimate of energy capacity of the system based, at least in part, upon the indicium of location and the indicium of facility size;
• generating and displaying a bill of particulars comprising a listing of components required to meet an estimated capacity of a modeled system;
• enabling a user to adjust at least one parameter of the modeled system comprising at least one of:
• a facility size;
• an amount of daily energy consumed by a facility to be powered by the system;
• a duration of a backup to be supplied by the energy storage system;
• an initial estimate of energy capacity of solar energy generation and/or capacity of energy storage;
• determining an updated estimate of capacity of the system based, at least in part, upon the adjusted at least one parameter.
