Abstract: Solar rooftop photovoltaic installation is among the most prominent setups in our nation to meet demand for energy in an inexpensive manner, encompassing both ground and roof mounted plants. As of February 28, 2021, the country's installed solar energy capacity was 39,083 MW. The major focus of this article is on the essential features of the design and installation involved in the system setup, including not only the technical design for a PV system, but also other critical components such as installation site appraisal of a particular rooftop to the final cost analysis. As an outcome, the paper's discussion will provide a general grasp of how a rooftop solar system is processed in this nation from an engineer's perspective.
