NEDO's activities on research, development and demonstration for photovoltaic systems

Abstract

An outline of PV systems developed by the New Energy Development Organization (NEDO) is presented. Support technologies for PV generation were investigated. The implementation of these systems reveals important information about system interconnection and control technology such as reverse power flow protection, instantaneous switching, suppression of voltage fluctuation, and harmonic distortion. The development of components such as solar cell arrays, inverters, batteries, and so on is discussed.<>
