55 months generation of electricity with 4kW photovoltaic power generation system

摘要

During the past few years the nationwide monitoring project of residential photovoltaic power generation system has been spread throughout the country. These are very nice to defend the earth from environmental pollution. During 55 months generation of electricity with 4kW photovoltaic power generation system of the author was measured and confirmed the practicality. The system was helped by the national monitoring project in 1997.19,032 [kWh] of electric energy were supplied from solar energy from January 1997 to August 2001. The electric energy was self-supported from the PV-system. The value of PV-power/global solar radiation of the system was about 0.86[kWh/MJm{sup}(-2)].
