Harnessing Solar Power: Feasibility and Advantages of Photovoltaic Facadesin Indian Cities

Introduction: In the recent years, the growing concerns about the energy consumptions in buildings has led the research community toward the development of sustainable building energy policies and the promotion of the next generation buildings, such as net zero-energy building. In order to reach the NZEB goal, the use of innovative building concepts and materials, along with the implementation of energy efficient and renewable technologies are becoming more and more relevant. To this twofold aim, advanced Double Skin Façades (DSFs) were identified as one of the most promising responsive building elements and have gained an increasing attention. DSFs became an important architectural building element due to their high potential to provide energy, comfort, aesthetic and structural advantages, as well as to provide space for integrated PV panels. India is one of the nations that receive ample solar radiation during the year. For the context 5000 trillion kWh of solar energy incident over India's land area annually. [1] The effective use of this energy would fulfil the country‘s power needs as a whole. The discovery of the photovoltaic (PV) effect allows for the conversion of direct sunlight into electricity, a more valuable type of energy compared to heat. A growing number of successful projects around the world demonstrate that conventional building cladding and roofing can be effectively replaced with electricity-generating PV materials. Properly designed PV systems usually have provisions to allow natural air circulation to cool the PV surface and avoid possible structural damage. The integration on facade or using it as a cladding wall material is different for each building. envelope systems. There are different construction systems and different types of PV modules. The purpose of this research is help to understand PV systems, their construction technology on facades more specifically. Also, this research examines the advantages and disadvantages of using PV on building facades, classification of PV and feasibility in context of India.
