This paper deals with the potential of active solar energy generation based on Building Integrated Photovoltaic (BIPV) in Indian cities. Photovoltaic (PV) technologies are integrated into the building utilizing solar radiations to generate clean power, making the building a self-reliant power production hub. Power scarcity and heavy consumption give a lot of stress over the non-renewable power production methods like burning of coal, fossil fuels, and hydropower generation. These methods of power production are not sustainable and show their adverse effects on the ecosystem in the long run. Photovoltaic panels are designed to capture the solar radiations, thus converting the solar energy into electrical energy but certain limitations of photovoltaic (climatic, technical and storage) restrict efficient power generation. Three primary case studies of power generating buildings were conducted, showing the stress reduction on power distribution from the grid. A model for integrating PV technologies in buildings was proposed based on TRIZ methodology and results obtained from the case studies. This proposed building model could work as a power production house which gives back unused power to the grid, thus reducing the carbon emission level. The combination of these technologies would play an important role in the development of solar powered home; acting as the basic unit of solar cities. The results of solar integration would be seen as additional units of solar energy captured from the environment and would reduce stress on non-renewable and polluting sources of energy. Moreover, many Indian villages and remote areas would be provided with clean electricity solving the issues of power shortages and load shedding. This methodological analysis shows that solar power generation can significantly advance a building’s sustainability through improved energy performance and renewable energy generation.
