What are bifacial solar panels?

Bifacial solar panels are solar modules capable of generating electricity from both the front and the back. They utilize bifacial solar cells, with the back typically encapsulated in transparent materials (such as glass or transparent back sheets).

Will bifacial modules increase power production?

There is no doubt bifacial modules will increase power production. The question is how to accurately measure the cost of the bifacial plant, and how to accurately predict the power production with all of the variables accounted for.

Are bifacial solar panels a good investment?

Bifacial solar panels demonstrate clear advantages in power generation, adaptability to installation environments, and land utilization efficiency, especially in high-reflectivity environments where they can significantly enhance energy generation. However, initial investment and structural complexity are factors to consider.

Do bifacial solar panels produce power from two directions?

Due to the ability of bifacial solar panels to produce power from two directions, bifaciality has become an important metric for assessing their performance.

How do you calculate bifaciality of a photovoltaic module?

For example, under Standard Testing Conditions (STC), if the test power of the back of a bifacial photovoltaic module is 350 watts and the test power of the front is 500 watts, the calculation for bifaciality would be 350/500 = 70%. This means that the back contributes 70% of the power generation capability compared to the front.

How bifacial solar panels are gaining market share?

Gradually Achieving Commercialization: Market share around 70%. Minimum Height Above Ground: Generally speaking, the higher the bifacial solar panels are installed above the ground, the more pronounced the gain effect from the back side.
