Are Bifacial Solar Panels Worth It? Monofacial Vs Bifacial Solar Cell
28th May 2021
Solar technology is a rapidly evolving area in sustainable energy development. We are yet to globalize solar power for efficient energy consumption and working. With up and coming trends in solar panel expansion, it is essential to know about different types of solar panels. In this article, we will primarily focus on bifacial solar panels.
What are bifacial solar panels?
Unlike the mono-facial solar panel that captures sunlight on one light-absorbing side and reflects away the light that cannot be absorbed, bifacial solar panels have light-absorbing cells on both sides. This means that bifacial solar panels can absorb light reflecting from other surfaces as well. Dual glass or transparent black sheets are used in the manufacturing of these panels.
Like every technological advancement, there are advantages and disadvantages of bifacial solar panels as well. Let’s look at the advantages as well as the challenges in using bifacial solar panels.
Pros of bifacial solar panels
Here are some of the benefits of using bifacial solar panels.
There is a significantly higher rate of solar efficiency when compared to mono-facial panels. There is a higher energy output from the same number of panels, and studies show there is almost
Since bifacial panels are covered with tempered glass on both sides, which makes them more durable. Tempered glass is stronger and long-lasting and guarantees a long time of usage for bifacial panels.
Trackers are systems that adjust the angle of solar panels throughout the day for optimal sunlight absorption. The problem with trackers is that there could be a lot of malfunctions from the moving parts, whereas bifacial solar panels do not need to move to absorb light energy.
Cons of bifacial solar panels
There are some negatives in using bifacial solar panels. They are:
Bifacial modules can be used more effectively on flat or almost flat rooftops because you can control the angle of the panels to your liking. But on a sharper roof incline, there is no space for a bifacial solar panel. A bifacial solar panel requires room to be mounted over, and a multidirectional roof would perform negatively for a bifacial solar panel.
As the technology is newer and advanced, bifacial panels cost more than mono-facial solar panels. Since bifacial panels also produce more energy, it is wise to calculate whether that amount of energy is viable for your homes.
It is preferable to install a reflective surface under your bifacial panel if the ground is grass or dust. Since the unit is bifacial, if there is no light to be reflected onto one side of the panel, there is no use to the dual panelled solar unit.
Before buying bifacial modules for your homes and business, you must be wary of the benefits and disadvantages of bifacial solar panels. With the large amount of energy produced by bifacial modules, the power output is not predictable and would require the advice of experts in the field.
