Performance Ratio and Loss Analysis for a Grid-Connected Solar Photovoltaic System: Case of the 7MW Plant in Malbaza, Niger

The use of solar energy in sunny countries is an efficient way to overcome the shortage. interest this not only economic but also environmental, as it emits few greenhouse gases. Niger, a vast landlocked country Sahel, characterized by average sunshine duration 8.5 hours per day and estimated level around 5 7 kW/m2 day. However, rate access electricity Niger remains very low. To address problem, 7MW photovoltaic power plant has been built State town Malbaza. It composed monocrystalline panels injects its into national grid. objective study compare performance ratio determined measurements with that obtained simulation under PVsyst order evaluate efficiency. based on annual production data, recorded at site, from 1 January 2021 31 December 2021. values global irradiation produced system injected grid are respectively 249.86kWh/m², 1225.25MWh 972.62MWh; those ambient temperature (PR) 29.78°C 0.795. losses caused meteorological phenomena linked technologies various components evaluated 20.10%.
