<p>In this manuscript, one of the higher educational institutions located at Lat. 13.62ON; Long. 79.29OE; Alt. 226 M is considered and the roof architectures and  orientations of seven sheds being utilized as six workshops (WS) and one central stores (CS) are studied. NASA-SSE satellite synthetic data is used for resource assessment and PV System 7.3 software is used to estimate the annual GHI at the concerned site. Physical inspection and measurement survey has been carried out to exactly obtain the shed orientation, azimuth angle and roof dimensions including slope angle. Based on these data, gross capacity of solar PV collectors that can be installed on the roof of sheds and corresponding energy yield is estimated. Different cases have been exercised to create real-time feasibility for erecting solar PV system on the roofs of the concerned sheds. The obtained results are so intensive that for the WS and CS sheds, the daily normalized production in kWh/kWp/Day and energy yield is more on the south facing roofs (CS & WS) followed by west (WS), east (WS) and north facing roofs (WS & CS). In comparison to the vertical installation, the specific production in kWh/kWp/Annum is more with the horizontal installation of PV modules on either side of the exposed roofs for WS and less for CS. The total maximum energy that can be generated on the roofs of total seven sheds is about 9,69,566 kWh/Annum which may reduce about 824.12 Tons of CO2 emissions per annum. It is an appreciable figure and could pave a path for establishing green electricity. This research has been carried out to inspire the enthusiastic higher educational institutions to think for installing considerable capacity of solar PV system on the roofs of their workshop sheds and contribute for establishing green electricity.  In this manuscript, one of the higher educational institutions located at Lat. 13.62ON; Long. 79.29OE; Alt. 226 M is considered and the roof architectures and  orientations of seven sheds being utilized as six workshops (WS) and one central stores (CS) are studied.
