Solar Energy Resource Potential Assessment for Industrial Rooftop Area: A Case Study of Huangpu District

Abstract

The major energy strategy of China has made a specific goal for the development of renewable energy. For the city of Guangzhou, the government has made a target of the installation of solar PV development: up to 2000MW by 2020. Huangpu district is one of the national economic development zone (EDZ) in Guangzhou, the district government has planned to install 302MW solar PV capacity in any form across all building sectors by 2020. This paper contributes to current renewable energy development planning by combining spatial analysis tools and urban planning data together to evaluate the solar energy resources and technical potential for the solar PV installation on industrial rooftop in Huangpu district in a more accurate method. Results shows that the technical potential for industrial rooftop solar PV in the Huangpu EDZ was estimated to be 649MW with a total effective solar PV panel area of 3,956,402 m2. It shows that the technical potential is enough to reach the solar PV target set by the government if we only consider the industrial buildings.
