Abstract:
Reducing greenhouse gas emissions can be achieved by switching to renewable energy systems, such as photovoltaic panels. The use of renewable energy sources offers the advantage of sustainability in all aspects related to the development of the energy sector. Photovoltaic technology has become a major player in the global electricity generation sector and is currently one of the most developed renewable energy sources being scalable from residential to commercial applications. The aim of the study is to analyze the performance of an on-grid system coupled with the national electricity supplier using monocrystalline silicon photovoltaic panels. The 5.27 kW system is installed on the roof of the house, with a tilt angle of 26o inclination to the horizontal, in the SV-NE direction, in Măgurele, Ilfov County. Data were collected between September 2021 and February 2022, thus covering the autumn-winter seasons, a critical period because of the low solar potential. The collected data were analyzed in relevant, real operating conditions and correlated with the weather conditions: cloudy sky, the amount of radiated solar energy, and temperature. A protocol has been established for interpreting the data collected in relation to the theoretical values.
