Potential Impact of Consumer Intention on Generation of Waste Photovoltaic Panels: A Case Study for Tokyo

As the world moves toward decarbonization, Japan is experiencing a rapid introduction of solar modules. However, country does not have an adequate social system for managing waste photovoltaic (PV) panels. A generation estimate would be needed to do this effectively. Usually, estimation performed by assuming that lifespan distribution primarily dependent on mechanical life target item. considering continuing improvement in panel quality, consumers consider replacement or disposal before failure product. Therefore, study consumer intention, we surveyed potential decision making replacement/disposal via questionnaire survey and attempted include result as part our estimation, which, knowledge, has never previously been carried out. Considering owners’ making, was advance compared with case where only assumed panels housings. This indicated huge number potentially reusable generations. In addition failure, due decisions should also considered estimating maximum waste. Policy makers prepare appropriate recycling advance, possible reuse panels, which fits current situation oriented circular economy.
