옥상녹화에 따른 PV발전량 차이에 관한 실험적 연구

As environmental issues have been rising to international interest in various areas in the 21st century, effort has been continuously put to use and develop various energy resources such as renewable energy as energy usage plans have changed. Medium and long term greenhouse gas reduction goal and reduction amount of countries until 2050 are decided at the 15th Climatic Change Convention Conference of the Parties and in our country's case, a medium and long term reduction goal of 30% compared to the predicted emission until 2020 was proposed. Therefore, this study measures the PV module back side temperature, insolation, generation, conversion efficiency value by using MP-160, TC selector MI- 540, PV selector MI- 520 equipment, which are I - V Curve Tracers, by installing single crystal and poly-crystal PV in green roof and non-green roof places. To confirm the possibility of increase in efficiency for solar cell development through green roof that lowers roof temperature, PV module were installed in each green roof and non-green roof sides to compare efficiency fall and difference in generation according to temperature change. For this, it could be confirmed from the PV system installed on the green roof and non-green roof that the back side mean temperature dropped and showed better generation and conversion efficiency for green roof on both single crystal and poly-crystal.
