In large power stations, bifacial double-glass photovoltaic modules can continue to generate electricity while receiving solar radiation on both sides, increasing power generation and total output. Compared with traditional single-sided photovoltaic modules, its power generation can be increased by about 25%.
Fishery farming is combined with photovoltaic power generation. A photovoltaic panel array is set up above the water surface of the fish pond. The water below the photovoltaic panels can be used to raise fish, shrimp, ducks, and geese. Make full use of limited space resources, power generation can be generated from the top, and breeding can be done from the bottom.
In the construction field, double-sided double-glass photovoltaic modules can replace traditional curtain wall materials, reduce the burden on buildings, and at the same time use the double-sided power generation function to provide clean energy and lighting for buildings.
The double glass design makes the entire photovoltaic panel as transparent as ordinary glass, ensuring the transparency of the sunroom's view. It can achieve the perfect combination of visual effects and power generation functions. With high power generation efficiency, corrosion-resistant and long service life.
