Lifetime and performance alteration of photovoltaic panels, the case of Aerzen, Germany

Abstract

Solar energy is unlimited, flawlessly, sustainable and among of the most preferred renewable energy source. The rapid development and the increasing demand in solar energy technologies provided an increasing the production and played an important role for reducing costs. Thousands of manufacturers around the world produce solar panels however solar panels are also exposed to aging during their lifetime. This aging of the solar panel is generally expressed by the manufacturers as 10% generation performance loss in 10 years and 20% in 25 years. However, solar panel technology is not a very old technology and these statements on aging are in need of confirmation. So, in this study, the data of a solar power plant that has been operating for about 13 years has been examined in detail and the same plant has been modeled with numerical programme for the case of Aerzen, Germany. Panel aging was discussed by comparing the simulation data with the experimental data.

“…Yenilenebilir enerji kaynaklarından elektrik enerjisi üretiminde ilk zamanlar daha çok hidroelektrik santraller kullanılmaktayken teknolojinin gelişmesiyle birlikte günümüzde ise hidroelektrik santrallerin yanı sıra rüzgâr enerjisi ve güneş enerjisi santralleri de popülaritesi artan elektrik enerjisi üretim kaynakları haline gelmiştir. Bu durumun en önemli etkenleri; küresel ısınma, fosil yakıtların azalması, rüzgar ve güneş enerjisi teknolojilerinin üretim maliyetlerinin azalması şeklinde sıralanabilir (Rüstemli ve Tekev, 2021;Dinçer, 2021).…”
