Bifacial solar panels, more efficient

Solar panels, also known as photovoltaic panels, are a type of technology that converts the energy from the sun into electricity. These panels consist of solar cells that are made up of layers of silicon, along with other materials that allow them to capture and convert solar radiation.

Then have you heard of bifacial solar panels?

What are bifacial solar panels?

Bifacial solar panels are a type of photovoltaic (PV) panel that can capture energy from both sides of the panel. This unique design allows them to absorb sunlight from the front and rear of the panel, increasing the overall energy output of the system.

The construction of a bifacial solar panel is similar to traditional PV panels. The difference lies in the addition of a transparent backsheet, which allows sunlight to penetrate through the panel and reflect off the ground or other reflective surfaces. This reflected light then enters the back of the panel, which can increase energy production by up to 30%.

 Advantages of bifacial solar panels

The wear resistance, insulation, waterproofing, and load-bearing capacity of glass surpass those of the back panel, mitigating problems like local cracking of components and facilitating stable and dependable component power generation. Furthermore, the fire resistance level of bifacial solar panels has been elevated from the conventional C level to A level, augmenting their fire resistance capabilities significantly.

The bifacial solar panel has a larger thermal capacity and a smaller temperature rise rate compared to ordinary ones, making it less susceptible to cold and hot shocks. Moreover, the thermal diffusion coefficient between the glass and the backplate is more than 7 times different. The use of double glass components can effectively solve the problem of component heat dissipation and reduce heat spot damage.

The use of double glazing in bifacial solar panels significantly increases their weather resistance and energy efficiency compared to traditional ones. This is particularly beneficial in areas with high humidity, acid rain or heavy salt mist, agricultural greenhouses, and strong wind and sand. In these locations, the advantages of bifacial solar panels are even more pronounced.

Bifacial solar panels are highly efficient because they can capture energy from both direct and indirect sunlight. The performance of bifacial solar panels is mainly affected by the system design and installation environment. Under the same nominal peak power and installation location, the bifacial solar panels have a power generation gain of 15% to 20%; After increasing the height of the components and the ground albedo, the gain can reach 30%;
