Abstract
Rooftop Low Angle Tilted Photovoltaic Installation under Polish Climatic Conditions
Highlights
The use of solar radiation energy in photovoltaic (PV) technology plays a significant role in the process of transition to alternative energy sources and transformation of the global energy system
The performance ratio of the photovoltaic systems increased in recent decades from 70% before 2000 to 80-90% reported nowadays [Photovoltaics Report, 2020]
The 15 kWp rooftop installation was monitored over the entire year 2019 and the influence of real external conditions on the performance parameters was evaluated on monthly and seasonal basis
Summary
The use of solar radiation energy in photovoltaic (PV) technology plays a significant role in the process of transition to alternative energy sources and transformation of the global energy system. The Sun is the most powerful renewable energy source; the use of photovoltaic modules spreads around the world, in places at various latitudes. The growing popularity of photovoltaics is influenced by the improvement of the price to efficiency ratio due to a number of modifications introduced recently to silicon modules of first generation. The laboratory efficiency of 26.7% was reached by monocrystalline Si solar cells and 22.3% by multi-crystalline Si [Green, 2021]. These achievements indicate the potential for further rise in the PV efficiency, on an industrial scale. The performance ratio of the photovoltaic systems increased in recent decades from 70% before 2000 to 80-90% reported nowadays [Photovoltaics Report, 2020]
