Potential for Integrating Solar Rooftop Photovoltaic System with Rain Water Harvesting and Electric Vehicle Charging Facility: Designing a Multicriteria Framework

- In this paper we attempt to capture technical, socioeconomic and environmental effects with a conceptual model that combines three environmental interventions, rooftop solar photovoltaic system (RTPV), rain-water harvesting system (RWH) and solar powered electric vehicles (EV). We develop a framework for multicriteria analysis considering technical, socio-economic and environmental criteria. This framework can be applied to case studies to obtain the numerical values of the scores using data specific to a particular region. We conceive four scenarios based on how the three systems, RTPV, RWH and EV are combined. For each scenario we consider a multicriteria score as well as the scores for each criterion to analyze the performance of each scenario in terms of the three criteria in consideration. The multicriteria score gives us the overall score of each scenario taking all three criteria into consideration. Comparing the multicriteria score we can determine which scenario performs better in terms of the three criteria providing a direction for framing policy models. We can also compare the four scenarios in terms of each criterion separately and take policy decisions accordingly.
