HOUSEHOLD SIMPLIFIED PHOTOVOLTAIC POWERSYSTEM

摘要

PURPOSE:To effectively utilize a photovoltaic power-generation system by a method wherein the photovoltaic power-generation system is popularized and promoted widely to a general household so as to be installed simply and at low costs. CONSTITUTION:A household simplified photovoltaic power-generation system is composed of a solar-cell module 5 which is laid on a roof part 3 for a carport 1 and in which many solar cells are arranged side by side so as to be connected to each other, of a household power conditioner 8 which is connected to the solar-cell module 5 and which converts DC generated electric power into AC electric power so as to be supplied to a load inside a household and of a battery charger 9 which converts the AC electric power from the power conditioner 8 again into the DC electric power so as to be stored in a battery 15 for gasoline car of an electric car 15 or which converts the stored electric power into AC electric power so as to be supplied to the load inside the household. The photovoltaic power generation system can be linked to a distribution system by a connecting plug 12 at the tip of a vord 11 extended from the power conditioner 8 and the battery charger 9.
