Method for computing the propriet installed capacity of the solar cell generating system

摘要

A method for computing an optimal installation capacity of a solar cell generation system is provided to enable the solar cell generation system to supply electric power to a self-generation house smoothly in connection with a usual commercial power system by computing the optimal installation capacity when the solar cell generation system is installed to the self-generation house. Total electric power usage of the self-generation house is checked(S2). Minimum and maximum load according to the total electric power usage is compared and analyzed(S6). It is checked whether or not the minimum load is bigger than the electric power generated from the solar cell generation system(S10). The optimal installation capacity is computed when the minimum load is bigger than the electric power generated from the generation system(S12). Inverse power transmission of the electric power generated from the solar cell generation system is prevented when the minimum load is smaller than the electric power generated from the generation system(S14).
