Bifacial Solar Panels – How much extra power produce ? The Albedo Factor

The true benefits of bifacial solar panels – Measured data from Elite Solar and Renesolar 430watt and 550watt panels

We measured that bifacial panels generate more electricity due to the amount of reflective light on the back side of the PV panel. Bifacial panels are fabricated with a glass-to-glass structure. The back side is fully transparent and absorbs a significant amount of daylight. The amount is reflective light is determined by the albedo factor.

Our technical team collected real data from solar projects around the world and we found out that bifacial solar panels can generate up to 32% more electricity from the sun.

On cement, the extra energy is +13%
On grass +10%
On land/soil +12%
White paint +32%

If white paint is not possible to apply or it is proven an expensive material, then a simple white PVC foldable material will be sufficient to increase the albedo factor to 30%

We listed the 8 possible applications where the benefits of the bifacial panels will prevail.

In the video from Tiktok, we measured in real time the reflection effect when the panels are connected to a single micro-inverter

Time to earn some money from your fence.

One of the most common applications of bifacial panels is the erection of fences and walls that are made of photovoltaics, your property will look more modern and technologically advanced and at the same time you will generate electricity from a surface that was nearly impossible to get any benefits before. The size of the 550watt panel is ideal for fencing with height 2.25 meters and 1.2 meter wide.

The cell degradation is lower when glass is used on both sides of the panels. The life expectancy is 35 years. The pre-2015 solar panels had a maximum life cycle of 20-25 years.
