Green Electricity Share Enhancement Through Rooftop Solar PV System on Institutional Sheds

Abstract

Different cases have been exercised to create real-time feasibility for erecting solar photovoltaic (PV) system on the roofs of the seven sheds being utilized as six workshops (WSs) and one central store (CS) within a higher educational institution. The obtained results are so intensive that for the WS and CS sheds, the average daily normalized production (ADNP) in kWh/kWp/Day is more on the south-facing roofs (4.20) followed by west- (4.06), east- (3.96), and north-facing roofs (3.78). The mean average additional energy (MAAE) of about 11.27% and 2.52% can be generated on south- and west-facing roofs compared to the north- and east-facing roofs, respectively. In comparison to the vertical installation (VI), the average specific production (ASP) in kWh/kWp/Annum is more with the horizontal installation (HI) of PV modules on either side of the exposed roofs for WS (1459.25) and less for CS (1454.5). The total maximum energy that can be generated on the roofs of total seven sheds is about 969 566 kWh/Annum, which may reduce about 824.12 ton of CO2 emissions per annum. It is an appreciable figure and could pave a path for establishing green electricity. The outcomes of the presented study address the energy sustainability challenges of a higher educational institution.
