The Advantages and Disadvantages of Bifacial Solar Panels

By Brian Douglas  May 22, 2021

With the rapid increase in demand, the solar panel manufacturing industry is turning its heads to the advanced side of the page. Companies are showcasing their innovative ideas with consumers everywhere, thus building up a healthy competition. Bifacial solar panels, though a recent induction in the solar market but they cannot put aside either as they stand apart from the regular solar panel. 

The name itself is self-explanatory. It is a solar panel that is pretty much like a mono-facial solar panel that can store sunlight from both sides of the solar panel. Bifacial solar panels are capable of producing solar energy by utilizing both sides of the solar plate. In bifacial solar panels, the rear side of the panels is kept transparent by using tampered glass instead of a reflective coating. The face of the solar panel absorbs the direct sunlight, and the rear end absorbs the reflected light from the surface. Hence it increases the production capacity of the installation.

Advantages of Bifacial Solar Panels.

  1.  Maximum efficiency:

The bifacial solar panels tend to be more efficient than the mono facial panel. These are capable of using both sides of the solar panel to produce more solar-powered electricity. Hence, they actively increase the overall production efficiency of the system.

    2.  Small installation space:

If your power needs require a good number of solar panels but the installation site does not have that much space, you can still meet your energy requirements by installing bifacial solar panels. Their two-way build can help you meet your energy goals and that too without worrying about having not enough space. 

     3.  Durability:

The tampered glass is a crucial ingredient in the manufacturing of bifacial solar panels. It increases the light-absorbing capacity and also gives a sounding edge in terms of overall durability. The bifacial solar panels are more resilient towards winds and other factors that may compromise the general efficiency of the solar panel.

    4.  Backup energy production in Bad Weather:

The bad weather can directly affect your production capacity if you are using mono-facial panels. However, things are different when using bifacial panels as they continue to work. Even though the front side of the panels is affected by the bad weather, the rear side continues to work efficiently unaffected by the troublesome weather.

    5.  The angle of installation:

With a bifacial solar panel, there is no to worry about any particular angel for installation. The bifacial panels are suitable for any position without worrying about the efficiency of the system. Unlike mono-facial panels, they can be installed even at 90 degrees of inclination, and still, the efficiency won’t drop.

 Disadvantages of Bifacial Panels.

With all the good things about bifacial, there are certain drawbacks to them as well. These disadvantages are:  

  1.  Overweight:

The bifacial solar panels have a fair share of weight on their side. They are extremely heavy and require a great deal of care in handling. Their heavyweight can also compromise the strength of the roof if the installation is roof-mounted. Their heavyweight means their mobility is limited, making their maintenance is a bit difficult. The customer should hire a professional solar engineer to assess the structural integrity of the roof before installation. Also, for installation, the customer must acquire experts who profess in handling such overweight beasts of the solar industry. 

      2.  Overpriced:

The bifacial solar panels are not only overweight but also slightly expensive than the mono-facial panels. Their installation cost edges to that of mainstream installation. But that also means they are equally cost-effective. However, bifacial solar panels offer enhanced production of energy which fills in for them for being expensive. Keeping that in consideration, they equal the overall cost of the energy compared to mono facial.

     3.  Reflective Surface:

To fully utilize the bifacial solar panels. That is why these panels require installation on a surface that reflects the sunlight. However, by painting with light-reflecting colors, they are pretty much suitable anywhere. It significantly increases the installation cost, thus making an already costly installation a bit more expensive. 


Bifacial solar panels have their pros and cons, yet their impact on the solar market is remarkable. They offer a lot of advantages and could turn out to be a perfect buy for you.
