3-Years Energetic and Economic Analysis of a 30kWp Rooftop PV Power Plant

A 30 kWp rooftop solar photovoltaic (PV) power plant was modelled using energy balance equations, 3-year production and its economic return is calculated according to the feed-in tariff agreement. Electricity on an hourly basis, actual results simulation were closely compatible. The system generated 45.35 MWh, 47.05 MWh 46.34 of in year 1, 2 3, respectively. It has been observed that performance ratio PV varies between 84.50 % 90.27 %, while capacity factor 17.26 17.63%. While 93.90 electrical injected into grid over a period, 46.40 taken from grid. price electricity consumed FIT conditions at time installed, payback period as approximately 6 years.
