The photovoltaic industry is characterized by its continuous search for efficiency and for ensuring that solar modules or panels make the most of each ray of sunlight. In this search, countless types of solar panels have been designed with different technologies such as bifaciality.

What is a bifacial solar panel?
If we make a small definition of what are the bifacial panels, We could say that they are basically panels capable of producing energy on both sides, taking advantage of the light that is reflected on this second side. Thanks to this, bifacial panels can represent a significant improvement in terms of production with respect to monofacial ones.
What advantages does a bifacial solar panel have?
Increased energy production
With these bifacial modules we can achieve better energy production compared to conventional monofacial panels. In the case of panels Lion de recommend se can reach a improvement of up to 30%.
Versatility
Being panels with the ability to produce energy on both sides, we have the possibility that these can be installed in places that enhance the absorption of clear light, such as white or snowy ceilings.
Design
The design of these panels makes it possible for them not only to generate energy, but at the same time to be used as pergolas, awnings, barriers and become an aesthetic element of our installation.
The 3 factors to consider when installing bifacial solar panels
To get the most out of our installation of bifacial modules we can't just install them and expect them to run at peak production without proper advice. We will need a previous study or a section of engineering to help and advise us to enhance the advantages that these panels provide us. There are 3 essential factors when installing our bifacial panels:
1- Albedo
The albedo is the amount of radiation that the ground reflects.. Under normal conditions, the percentage that the earth reflects is 35%, always depending on the type of soil, the color and its composition. If, for example, we have a white floor due to snow, levels of up to 90% albedo can be reached, while if we have a dark gray floor made of tile, it is difficult to reach 30%.
Why is albedo important for bifacial panels?
Obviously, the strong point of bifacial panels is that they are capable of receiving radiation from their opposite side, so albedo represents an important factor in increasing efficiency of these. For example, if we have a bifacial panel in our garage as an awning, it would be interesting for the floor to be white in order to reflect as much radiation as possible.
2- Installation height
Another factor to take into account when developing our installation of bifacial panels is the heightra. The height can help us at various points when it comes to increasing the production of our panels. For example, it can benefit when receive radiation from different angles not having a dense shadow. On the other hand, the height can help us control the temperature of the installation since, at higher altitudes, the modules are more likely to receive more fresh wind.
3- Distance between modules
Having a correct distance between modules will help us to take better advantage of both direct radiation and albedo, preventing the panels from shadowing each other.
