Description
技术领域technical field
本实用新型涉及太阳能光伏发电，以及太阳能光热利用领域。尤其涉及一种水冷式光伏发电系统。The utility model relates to the field of solar photovoltaic power generation and solar light and heat utilization. In particular, it relates to a water-cooled photovoltaic power generation system.
背景技术Background technique
光伏发电系统在一年内的不同季节以及一天内的不同时刻，太阳的照射时间以及照射角度是有相当变化的。这种照射角度的变化，导致传统的平板固定式光伏发电系统无论在地球什么地方，即使以最优化的方式放置，也无法避免“余弦效应”的影响。余弦效应造成的光伏电站年发电量的损失非常可观。同时由于太阳电池的价格至今居高不下，光伏发电成本太高；因此在目前太阳电池昂贵的形势下，努力提高单位面积太阳电池的发电量，是降低光伏系统单位发电量成本的重要方式。通过聚光方式增加太阳电池的辐射量是提高太阳电池发电量的理想方式，但是由于硅电池存在负温度效应，因此在提高单位面积太阳辐射的基础上，也提高了太阳电池的温度，降低了太阳电池的效率，并且对太阳电池的寿命也有很大影响。因此降低太阳电池的温度非常重要，目前太阳电池组件的降温措施主要采用空气自然冷却的方式，这种方式对于聚光系统得温度下降非常有限，因此有必要开发一种新型高效的降温方式。In different seasons of the year and at different times of the day, the solar radiation time and radiation angle of the photovoltaic power generation system vary considerably. This change in the irradiation angle leads to the fact that no matter where the traditional flat-panel photovoltaic power generation system is placed on the earth, even if it is placed in an optimal way, it cannot avoid the influence of the "cosine effect". The loss of annual power generation of photovoltaic power plants caused by the cosine effect is very considerable. At the same time, because the price of solar cells remains high, the cost of photovoltaic power generation is too high; therefore, in the current situation of expensive solar cells, it is an important way to reduce the cost of photovoltaic system unit power generation by striving to increase the power generation of solar cells per unit area. Increasing the radiation of solar cells by concentrating light is an ideal way to increase the power generation of solar cells. However, due to the negative temperature effect of silicon cells, on the basis of increasing solar radiation per unit area, the temperature of solar cells is also increased, reducing the temperature of solar cells. The efficiency of the solar cell also has a great influence on the life of the solar cell. Therefore, it is very important to reduce the temperature of solar cells. At present, the cooling measures of solar cell components mainly adopt the method of natural air cooling, which is very limited for the temperature drop of the concentrating system. Therefore, it is necessary to develop a new and efficient cooling method.
