Today,various activities to save energy are being conducted around the world. Even in our country, carbon reduction policy is being conducted for low carbon green growth and with this movement, effort to replace energy sources by recognizing the problems on environment pollution and resource exhaustion due to the indiscrete usage of fossil fuel is being made. Therefore, active study on renewable energy is inprogress as part of effort to replace the energy supply through fossil fuel and solar ray industry has rapidly developed receiving big strength of renewable energy policies.
The conclusion of this study measuring the surface temperature change of single crystal and polycrystalline PV module in green roof system and non-green roof system aspect are as follows. There was approximately 4℃ difference in PV module temperature in green roof system and non-green roof system aspect and this has the characteristic to decrease0.5% when the temperature rises by 1℃ when the front side of the module is 20℃ higher than the surrounding air temperature following the characteristic of solar cells.
It can be concluded that PV efficiency will be come better when it is 4℃ lower. Also, in result of temperature measurement of themodule back side, there was 5℃ difference of PV module installed on the PV module back side and green roof system side on the 5th,3℃ onthe 4th, 2℃ on the 5th to show decreasing temperature difference as the air temperature dropped, but is judged that there will be higher temperature difference due to the evapotranspiration latent heat effect of green roof system floor side as the temperatu rerises. Based on this data, it is intended to be used as basic reference to maximize efficiency by applying green roof system and PV system when building non-green roof system flat roof.
