浮動太陽能板發電系統 長遠而言，我們計劃在香港水塘逐步發展大型浮動太陽能板發 電場。水務署已於石壁水塘、船灣淡水湖和大欖涌水塘完成安 裝各自一組100 千瓦浮動太限能板發電系統，同時計劃於船灣 淡水湖發展大型淨動太陽能板發電場。 浮於水面上的浮動太陽能板發電系統可以自然冷卻太陽能電池 板，以提高整體發電效能。每組100 千瓦的浮動太陽能板發電 系統能產生相當於36 個普通家庭一年的耗電量，同時減少84 噸二氧化碳排放。 Floating Photovoltaic Systems Our long-term plan is to progressively implement large-scale floating solar farms at reservoirs in Hong Kong. The WSD has completed the implementation of 100kW-capacity floating photovoltaic (FPV) systems at the Shek Pik, Plover Cove and Tai Lam Chung reservoirs while planning to implement a large-scale floating solar farm at the Plover Cove Reservoir. The FPV systems on the water surface can naturally cool the solar panels to enhance the overall efficiency in electricity generation. The amount of electricity generated from each 100kW-capacity FPV system is equivalent to the annual electricity consumption of 36 average households with a reduction of 84 tonnes of carbon dioxide emission. 大欖涌水塘上的浮動太陽能板發電系 統已經完成。 Floating photovoltaic system is completed at Tai Lam Chung Reservoir. 除了從太陽能中採集可再生能源外，在水塘上安裝浮動太陽能板發電系統還有其他好處，包括減少水蒸發、抑制藻類生長、節省寶貴的土地資源， 以及提高太陽能電池板的發電效能。 每組浮動太陽能板發電系統，每年能產生約12萬千瓦時電力，為附近的抽水站或水塘的空氣壓縮機房供電。 Apart from harvesting renewable energy from the sun, there are additional benefits of installing floating photovoltaic systems (FPVs) over the reservoir surface, which include reducing water evaporation, suppressing algae growth, saving precious land resources and yielding a higher solar panel power generation efficiency. Each FPV system generates about 120 000kWh of electricity annually which will be used to power nearby pumping station or air compressor house of the reservoir. 點滴話你知 Did you know? 了解更多浮動太陽能板發電系統 Learn more about floating solar power system 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 70
