Assessment of Photovoltaic Potentials at Buguk, Sungsan and Younggwang Abandoned Mines in Jeollanam-do, Korea

Abstract : This paper assessed photovoltaic potentials at the Buguk, Sungsan and Younggwang abandoned mines in Jeollanam-do, Korea. To decide suitable areas for installing photovoltaic power (PV) systems, digital elevation models were used for analyzing terrain and shading effects. The estimated power productions and economic effects were analyzed using the solar radiation map and RETScreen software. The Buguk abandoned mine has the highest photovoltaic potential where the estimated power production is about 436 MWh/year, and equity payback is 9.1 years. Annual solar radiations at the Sungsan and Younggwang abandoned mines are almost same, however the photovoltaic potential at the Sungsan mine is higher than the one at the Younggwang mine since the Sungsan mine has larger area suitable for installing PV systems.
