Rooftop solar Photovoltaic (PV) plant – One year measured performance and simulations
In this study, 1-year real life performance of a 30kWp rooftop solar PV power plant installed at the Köprübaşı Vocational School of the Manisa Celal Bayar University was evaluated and is presented here. The PV plant is comprised of 116 polycrystalline modules mounted 15 cm proud of the roof surface...

In this study, 1-year real life performance of a 30kWp rooftop solar PV power plant installed at the Köprübaşı Vocational School of the Manisa Celal Bayar University was evaluated and is presented here.

The panels were tilted at 12° with horizontal and orientated at an azimuth angle of −20°. Measured power output of the plant was compared against the predictions of a spreadsheet based simulation model developed. Results were found to be in excellent agreement with the measured values.
