Assessment of Solar Energy Potential on Rooftops using GIS for Installation of Solar Panels: A Case Study


The objective of this study is to assess the potential of solar energy in a typical building using Geographic Information System (GIS). It also presents the detailed steps required to install solar panels on rooftops of building after assessment. The three step methodology has been adopted. In the first step, solar energy harvesting potential is determined followed by the calculation of electric energy demand in the area. Secondly, the capacity of solar panels and machines are worked out and installation details are calculated. This is followed by the final step of cost-benefit estimation. For a rooftop area of around 6840 m² and weekly AC/DC machine demand of 50 kWh, it was proposed to install 279 solar panel modules. The total capacity of solar power was worked out to be 69.75 KWp with specified production of 1571 KWp/KWh/year. The use of GIS brought down the time and effort and dependability on blue prints of building plan for calculating the study area. Solar power has the flexibility that it can be used anywhere and everywhere. Though the initial set up of solar power generation is costly, it is a viable solution for sustainable operation of the building.
