Field investigation of a photovoltaic power system for a telecommunications system

Nippon Telegraph and Telephone Corporation (NTT) introduced a photovoltaic power system (26 kWp) into a microwave radio station in Hokkaido, Japan, which was monitored and evaluated from September 1989 to August 1990. The authors describe the outline and results of this investigation. The photovoltaic power system supplied on average 92% of its output from sunshine throughout the year of study, satisfying the design forecast.<
