    Abstract: 太陽能電池模組在戶外發電時,吸收太陽發出來的部分輻射,其
    mm高的水冷卻系統可以提升發電量744.5 W,10 mm高的水冷卻系統
    可以提升發電量656 W,而在熱水回收方面, 5 mm高的水冷卻系統
    每日可回收溫度40℃的熱水為982.1公升,10 mm高的水冷卻系統每日
    可回收溫度40℃的熱水為1309.4公升;換算成家用電來看,5 mm高的
    水冷卻系統每日增加收益21.59度,10 mm高的水冷卻系統每日增加收
    益26.77度,日積月累下,增加的收益非常可觀。;When a photovoltaic module absorbs the solar radiation
    in outdoor, only a portion of energy can be converted to the
    electrical power and the most of the energy will become
    heat. The heat can increase the temperature and decrease
    the photoelectric efficiency. If the electrical power and the
    thermal power can be achieved from the solar energy at the
    same time, it will be greatly enhanced the photovoltaic
    system efficiency.
    In this study, the surface water-cooling and the water
    recycling methods were applied for photovoltaic modules
    to reduce the temperature of modules which can increase
    the output power of the modules. Besides, the thermal
    power can also be utilized by the recycled hot water. By
    combining the electrical and thermal powers, the
    efficiency of the photovoltaic module can be increased quite
    Finally, to compare a 5KW photovoltaic system with and
    without water cooling, the 5-mm and the 10-mm surface water-cooling
    methods can improve 744.5 W and 656 W of the output powers,
    respectively. Besides, the recycled 40 ℃ water can be
    achieved about 982.1 and 1309.4 liters daily for the 5-mm
    and the 10-mm surface water- cooling method, respectively. Totally,
    the electrical power can be reduced for 21.59 KWH and
    26.77 KWH, respectively.
