Abstract |
Sun, a free source of energy, has moved the world to consider photovoltaic (PV) system as green
renewable energy since fossil fuel power plant accounts for a significant share of greenhouse gas
(GHG) emissions across the globe. The output of the PV system is limited to many factors;
however, the acute accuracy of orientation (tilt and azimuth) angles exposes the PV surfaces to
high doses of solar radiations. Which increases the PV system output; in turn GHG mitigation
potential. This paper draws a relationship between accuracy of orientation angles impact on PV
system’s GHG mitigation potential. For reference, the accuracy of orientation angles in Pakistan’s
Capital increases the annual average daily solar radiations level from 4.02 (horizontal surface) to
4.39 ( 33.6 tilt and 180 azimuth) kWh/m2/d. Accuracy of orientation angles on multiple end
energy users (equivalent to 1 MW) PV system has potential to avoid additional 65.1 and 22.6
tonnes of CO2 equivalent and production of 15898
