Double-sided modules are photovoltaic modules that can generate electricity on both sides. When the sun shines on double-sided modules, part of the direct solar radiation and scattered light reaches the ground and will be reflected the back of the module. This part of light can be absorbed by the battery to improve the photocurrent and power generation efficiency of the battery.
Compared with traditional monocrystalline silicon photovoltaic modules, double-glass double-sided modules have the advantages of a long life cycle, low attenuation rate, weather resistance, better fire resistance, better heat dissipation, good insulation, easy cleaning and higher power generation efficiency. In addition, the glass structure of the double-glass double-sided module is more resistant to abrasion and corrosion, IP66, and the fire rating has also been upgraded from C to A of common crystalline silicon components. Therefore, solar street lights with double-glass double-sided components are more widely used for various environments such as deserts and seashores.
Studies have pointed out that the average power generation of PERC double-sided monocrystalline silicon photovoltaic modules is about 10.5% higher than that of common monocrystalline silicon photovoltaic modules.
The latest X4 series of solar street lights launched by PBOX Solar Lighting firstly choose frameless double-glass solar panels, which can maximize the power generation efficiency and have the features of easy installation and difficult to accumulate dust at the same time. It is the prominent representative of a new generation of high-efficiency solar street lights.
At present, the application of new energy technologies has developed rapidly, especially solar photovoltaic technology, and double-sided photovoltaic modules may become mainstream.
