The Simultaneous Impacts of Seasonal Weather and Solar Conditions on PV Panels Electrical Characteristics

Solar energy usage is thriving day by day. These solar panels are installed to absorb and produce electrical energy. As a result, the efficiency of depends on different environmental factors, namely, air temperature, dust (aerosols accumulated dust), incidence, photovoltaic panel angles. The effects real conditions factors power studied in this paper through testing tests. To study mentioned parameters precisely, two with angles used. case regarding region Tehran, Iran, summer winter seasons. results show that during higher than due temperature decrement. It discovered among pollutants, Al Fe have most share polluting affect efficiency. Moreover, measuring shows more amount comparison summer. important point studying effect tilt angle inconformity between incidence would result radiation absorption eventually loss also, installation deposited its surface.
