With the rapid development of the solar energy industry, the new bifacial solar panels have gradually appeared in the public’s field of vision. But many people still don’t know much about bifacial solar panels, so let’s learn about bifacial solar panels now.
1. What is a bifacial solar panel and how does it work?
Bifacial solar panels have solar cells installed on the front side but a transparent glass is installed on both the front and the back side, which makes it possible for both the front and the back side of bifacial solar panels to absorb the sun’s rays.
Bifacial solar panels work in a similar way to traditional solar panels, converting the absorbed solar energy into electricity. The difference is that due to the design of the transparent glass on both sides, bifacial solar panels can maximize the absorption of scattered and reflected light from the surrounding area.
According to the data given by the manufacturer, the backside capacity of a bifacial solar panel is usually about 70%~90% of the frontside capacity.
2. Advantages of bifacial solar panels
2.1 Increase power generation: Due to the design of bifacial solar modules, bifacial solar panels can maximize the absorption of surrounding sunlight to increase the amount of power conversion. According to relevant statistics, its power generation capacity is about 3%~5% more than that of traditional solar panels.
2.2 Long lifespan: most of the double-sided solar panels use bifacial glass structure, which greatly improves the stability and durability of the bifacial solar panels, but also to a certain extent extends the service life of the bifacial solar panels.
2.3 Long-term economic benefits: As bifacial solar panels can work longer and more efficiently, this can lead to more energy production, thus bringing long-term economic benefits.
2.4 Stronger low-light performance: Bifacial solar panels can capture the reflected and diffused light around them very well, so that even in low-light environments, bifacial solar panels can still show strong efficiency.
3. Disadvantages of bifacial solar panels
3.1 Higher cost: Due to the installation of two transparent glass structures, which makes the cost of bifacial solar panels generally higher.
3.2 Complicated process of adjusting the tilt angle: Due to the bifacial solar panel design, the installer can not only adjust the solar panel tilt angle according to the latitude when installing, but also consider whether the bifacial solar panels are able to absorb more reflected and diffused light.
4. Bifacial solar panels VS Traditional solar panels
Traditional solar panels are also very popular in the market, but how do we choose between these two types of solar panels? Generally speaking, bifacial solar panels are chosen in areas with highly reflective surfaces and highly taught installations. And in daily life, Traditional solar panels will be very suitable for our common residence. But there will be some difference in their cost.
