聚光太陽能發電的發展已有數十年，但是始終沒有被普遍使用，原因之一就是太陽光的收集與轉換的利用率並不高，太陽光的收集除反射鏡至接收器之間的散射散失之外，光線暴露在空氣中會受到環境熱光害影響，還有接收器接收光能於轉換中或飽和時的反射都造成光能的損失，且暴露於大氣的接收器也會有相當高的對流熱損，而其中耐高溫巨型發電機組更是難以製造且成本高昂，因而侷限了使用溫度大幅影響轉換效率，另安裝環境也佔地廣闊，失火時亦無法及時阻斷光能阻燃，並不適合於都會區使用，且會徒增運電成本及高溫光害而傷及鳥類與環境。Concentrated solar power generation has been developed for decades, but it has never been widely used. One of the reasons is that the utilization rate of collecting and converting sunlight is not high. In addition to scattering between the reflector and the receiver, the collection of sunlight In addition to dissipation, light will be affected by environmental heat and light damage when exposed to the air, and the reflection of the light energy received by the receiver during conversion or saturation will cause a loss of light energy, and the receiver exposed to the atmosphere will also have considerable losses. High convection heat loss, among which the high-temperature-resistant giant generator sets are difficult to manufacture and expensive, which limits the operating temperature and greatly affects the conversion efficiency. In addition, the installation environment also occupies a vast area, and it is impossible to block light energy and flame retardant in time in the event of a fire. , is not suitable for use in urban areas, and will increase the cost of electricity transportation and cause high temperature and light damage, which will harm birds and the environment.

藉由外部水源72之水壓及液位調節控制器來控制水箱液位來改變箱體10傾斜角度，以在不使用動力馬達的狀態下達到追日的功能以節省動力耗能，此外，可於日落之後調節控制器控制排放掉部分水箱內的液體，使箱體10傾斜角度復歸至晨間初始位置。The water pressure and liquid level adjustment controller of the external water source 72 is used to control the liquid level of the water tank to change the tilt angle of the tank 10, so as to achieve the sun tracking function without using the power motor to save power consumption. In addition, it can After sunset, adjust the controller to drain part of the liquid in the water tank so that the tilt angle of the tank 10 returns to the initial position in the morning.
本發明是藉由將箱體10設置於具有萬向調節件151的基座15上，並藉由液位調節控制器調節液位配重裝置70內的液體容量，以控制箱體10的頂面朝向太陽的位置，達到追日的效果，並且搭配具高光線集收的集熱裝置，以達到小型化及高陽光利用率的太陽能儲能系統。The present invention controls the top of the box 10 by placing the box 10 on the base 15 with the universal adjustment member 151 and adjusting the liquid capacity in the liquid level weight device 70 through the liquid level adjustment controller. Facing the sun, it achieves the effect of chasing the sun, and is equipped with a heat collecting device with high light collection to achieve a compact and high sunlight utilization solar energy storage system.
