Description
Technical field
The present invention relates to photovoltaic material technical fields, and in particular to a kind of solar panel frame waterborne and its preparation side
Method.
Background technique
With the fast development of world population and industrial economy, the reduction year by year of global air temperature warming and fossil fuel,
People increasingly pay attention to the development of green energy resource, establish the renewable energy extensive with solar energy equal distribution, effect on environment is small
Based on lasting energy system, become solve energy shortage and environmental security important channel.But construction is large-scale
Solar power station needs to occupy a large amount of soil, and being increasing with world population, and the contradiction having a large population and a few land is also increasingly
It is prominent.In order to reduce to the appropriation of land of resident compact community, solar power system waterborne is developed in the industry.
Solar power system waterborne can not only be built on ocean, can also be built in freshwater lake, optimal

(2) improve generated energy: water body has cooling effect to photovoltaic module, and assembly surface temperature can be inhibited to rise, thus
Obtain higher generated energy.According to the large-scale photovoltaic plant experimental contrast analysis waterborne in Japan Hyogo Prefecture, due to the cooling effect of the water surface
Fruit, solar panel generated energy increase about 14%.
(3) evaporation and algae reproduction are reduced: solar panel being covered on the water surface, evaporation from water surface can be theoretically reduced
Amount inhibits algae reproduction in water, is conducive to the protection of water resource.
(4) avoid component shading: comparison land, the water surface is relatively open, it is possible to prevente effectively from massif, woods etc. are to component
It blocks, solar energy irradiated area is uniform and light application time is long.
Solar panel frame is directly exposed to the external world, is first of protective barrier, sends out being applied to solar energy waterborne
