Abstract
Agrivoltaics, which can generate carbon-free electricity without reducing food self-sufficiency and has the potential to revitalize local communities, is expected to spread in Japan. However, in recent years, solar cell modules, installation methods, and the type of electricity selling methods have diversified, making it difficult to ascertain which combination is most profitable. This study examined the most profitable business model that maximizes profit using GAMS, a numerical optimization simulation model. The results showed that, compared to the conventional method of installing monocrystalline PV at the optimal angle, the combination of different solar cell modules increased the profit approximately 9.2 million yen during 20 years project of electricity sales. This result suggested that, rather than introducing expensive storage batteries, it is important for a profitable business to select the combination of solar cell that fits the demand electricity curve and sell as much electricity as possible to consumers.
