Study of the Merit of Battery Combined Photovoltaic Generation System for Residential House (2)

This paper describes the merit for power consumers brought by the combination use of photovoltaic generation and nighttime power storage using the storage battery. The merit of the combination system is calculated based on the insolation and consumers load pattern. The merit using insolation at the specific region and general load pattern has been already reported. This paper examines the influence due to regional and load pattern differences, and studies the changes of the merit and the optimal storage battery capacity. The other hand, it is difficult to measure the actual load pattern of the ordinary residence, so this paper uses the generalized load pattern to comparatively examine the difference in merit and optimal storage battery capacity from those for the actual load pattern.
