However, it is estimated that, on average, energy production can increase by up to 30%, although this is only a reference. It is also worth noting that production increases if the bifacial panel is placed on a white surface, since it reflects more light.
Advantages of bifacial panels
Now that you know how these double-sided solar panels work, let's point out the most important advantages they offer to users:
Greater capacity to produce solar energy with the same zambia email list installation space.
Improving energy efficiency.
Protection from the sun. As both sides are transparent, they do not impede visibility, but they do reduce the amount of direct sunlight a user receives.
They can be used on lighter surfaces, or in places where it snows more in winter. Remember that light colours have a greater capacity to reflect light and, therefore, the energy that can be absorbed is greater. To give you an idea, grass has a reflectivity of approximately 20%, while a surface covered in snow can increase it to 70%.
What are the disadvantages of bifacial plates?
Bifacial panels offer some advantages, but they also have certain drawbacks that you should take into account when deciding what type of photovoltaic installation you are going to carry out. These are the most obvious:
The cost is higher. Panels that have two sides made of solar cells are more expensive than monofacial ones. The cost of installation is also usually higher, since the assembly that must be done so that the light can be absorbed on both sides is more complex.
They are more limited when it comes to placement. Bifacial panels can be installed on any surface, but it makes the most sense to place them on surfaces that are lighter. Therefore, it may not be a cost-effective option for many people if they don't have a light roof, for example.
They require more maintenance. Cleaning and maintenance work on the cells is doubled, since the panel must be kept clean on both sides to ensure maximum efficiency.
Change in installation. If you already have conventional solar panels installed and want to replace them with bifacial ones, it may be necessary to make some modifications to the installation that is already in place.

Is it worth installing bifacial panels?
This is another of the big questions that users often ask themselves. And, as is often the case, there is no single answer, as it depends on each particular case.
