Outline of Final Research Achievements

A constant voltage control was can be applied to control for concentrator photovoltaic (CPV) system had high FF (over 0.8) in outdoors. Electricity generation of the CPV system with constant voltage control was calclated using electricity generation characteristics measured in our field test of the CPV system. The constant voltage control was a few percent smaller in the electricity generation than conventional maximum power point tracking control. This is a enough practical value. We proposed that a equation can be calculated to control voltage for the CPV system with the constant voltage control.
