Bifacial solar panels represent a new, emerging generation in the renewable energy sector. A solar panel, monofacial but which is also called conventional, uses only the sunlight incident on one side. In contrast, a bifacial one uses sunlight falling on both sides for energy generation. This fact increases the efficiency by a significant factor, making it an implementable technology for real-life applications toward sustainable solutions.
The structural design of bifacial solar panels allows light to pass through them and get reflected on their backside—by applying a transparent back sheet or having double glass layering. General energy output is bound to increase slightly with some reflective light from surfaces, including ground, snow, or water. All these efficient improvements can be done by properly placing reflecting material under them.
As compared to the one-sided conventional ones, the bifacial solar panels are likely to improve energy production by 10-30%. Simply put, a lot more power is created within the same footprint of the installation area and would, therefore, be great for use where space is, in general, constraining.
Being of the double glass constitution, the bifacial modules hold an extra strength against some environmental factors and high temperatures, significantly affecting the average period to which they last. In this regard, it promises a very long lifetime and low degradation rate.
