NEXT Group's own analysis of rooftop solar potential totaled 42.2 GW, providing more than 8% of the 2030 electricity generation (621.8 TWh) in the 10th Basic Plan for Electricity Supply and Demand, resulting in a greenhouse gas reduction of 15.2 MtCO2. GIS estimates the combined rooftop solar potential of residential and industrial buildings is at least 42.2 GW, but given that the analysis in this issue brief is based on conservative assumptions, the actual potential could be more than double that. Due to the recent decrease in the installation cost of solar power generation facilities and the increase in electricity prices, it is possible to recover the investment cost in as little as 3 years, depending on whether the subsidy is based on housing support (30kW) or building support (200kW).
