Economic Analysis of Different Business Models for Energy Prosumers: Focusing on the Rooftop Solar PV System Jongbaek An, Taehoon Hong*, Minhyun Lee ,Hakpyeong Kim

Abstract

Many countries have introduced various renewable energy sources to reduce carbon emissions. However, installing the renewable energy system without any energy storage system often fails to consume all of the produced energy, which then ends up being wasted. This study evaluated the economic performance of the surplus electricity trading of energy prosumer through three different business models. The proposed method can help energy prosumers to determine the business model with the highest profits and to evaluate the economic feasibility of peer-to-peer electricity trading for the future improvement.
