200 Watt 12 Volt 10BB Bifacial Solar Panel


This bifacial solar panel performs best when installed near highly reflective surfaces. Such as swimming pools glass, sandy, stony or snowy areas. Although the front of the panel still absorbs the majority of the sunlight, the bifacial models are capable of increasing energy production by 5%-20%. The exact amount of extra energy will depend on the environment surrounding the solar panels themselves.

FAQ

Question 1: What is 400W bifacial solar panel?

Answer: 400W bifacial solar panel is a photovoltaic device that can simultaneously absorb and convert sunlight into electricity from both the front and back sides. Compared to traditional single-sided solar panels, bifacial solar panels are able to generate more power in the same installation area, thus improving energy collection efficiency.

Question 2: How does the power generation efficiency of 400W bifacial solar panel increase?

Answer: 400W bifacial solar panel realizes the front and back double-sided power generation function by adopting specially designed transparent backsheet material and high-efficiency photovoltaic technology. This design allows the solar panel to utilize both direct and reflected light, thus improving the overall power generation efficiency. According to experimental data, the power generation efficiency of bifacial solar panels has increased by at least 5% compared to traditional single panels.

Question 3: How much wind and snow pressure can a 400W bifacial solar panel resist?

Answer: 400W bifacial solar panels are usually equipped with sturdy frames and protective structures that can resist strong wind and snow pressure. The exact resistance depends on the design and manufacturing quality of the product. Generally speaking, high-quality 400W bifacial solar panels are able to resist wind pressure of 2400Pa and snow load of 5400Pa.

Question 4: How to install 400W bifacial solar panel?

Answer: There are certain steps and specifications that need to be followed to install 400W bifacial solar panels. First of all, you need to choose a suitable mounting position and angle to ensure that the solar panel can maximize the reception of sunlight. Then, according to the installation instructions of the product, use the prefabricated brackets and fixings to fix the solar panel in the installation position. During the installation process, care needs to be taken to avoid damaging the surface and internal structure of the solar panel.
