Technical and Economic Analyis of Rooftop Photovoltaic System: A Case Study of a Residential Complex in Doha, Qatar.

Solar energy is one of the most widely available and abundant sources for energy generation. Several studies have shown that rooftop photovoltaic (PV) systems can efficiently generate electricity and support a country in its energy transition. In this work, the efficiency of solar energy generation in a residential housing complex, including 134 buildings, has been investigated. The solar PV rooftop potential was evaluated using an online map-based visualization application developed with in-situ solar radiation data acquired by the Qatar Environment and Energy Research Institute (QEERI), and GIS data provided by the Centre for GIS at the Ministry of Municipality (CGIS) in Qatar, including LiDAR elevation data, vector and raster representations of spatial data, and aerial photography for the area under study. The application runs as a GIS-based software platform and provides the estimation of rooftop PV systems yield alongside their financials, technical specifications, and carbon offsets in Qatar. The PV data output has been generated to compare the feasibility and techno economic analysis of rooftop PV systems showing a summary of installation scenarios in two different business models.
