Abstract

<p>Solar power generation, which converts solar energy into electricity, began to be developed in earnest after the oil crisis of 1973, and it has now become an important energy source that can solve the energy and global environmental problems. The authors have been involved in the development and promotion of such solar power generation for 50 years, and in 1992 installed the first solar power generation system with reverse power flow for an individual residence in Japan. This report describes the process of installing this system through many difficulties, and the results of longterm performance for 30 years after its installation. The average annual degradation rate of power output during the first 20 years of installation was 0.44%/year, which was good, but output clearly began to decline after 23 years, and the average annual degradation rate from 23 to 30 years was 5.96%. The degradation of polycrystalline Si solar cells was mainly due to an increase in series resistance.</p>
