Bifacial Solar Panel Guide: How Do They Work and Why They Are So Efficient

bifacial solar panels
Bifacial solar panels are designed to increase high efficiency for solar absorption through both sides of the panel. Bifacial solar PV modules initially hit the industry in the 1960s.

Key benefits of bifacial solar panels:

1. More sunlight to absorb – The bifacial panel can absorb sunlight that bounces off any objects and hits the panel’s backside. 2. Better cloudy day production – Bifacial panels can be more productive on cloudy days when more sunlight is absorbed. 3. Built to last – Bifacial panels are durable enough to sustain harsh weather conditions even with the extra solar cells on the back. What Is a Bifacial Solar Panel? Solar panels contain photovoltaic cells that convert sunlight into electricity. A bifacial solar panel is a solar module that is constructed in such a way to expose both the front and backside of the solar cells to sunlight so as to produce electricity from both sides of the panel.  

How Do Bifacial Solar Panels Work?

In many bifacial panels, the top solar cells perform as in traditional monofacial panels: they directly capture sun rays and convert them into electricity. The upgrade is that bifacial modules come with a transparent backside that are able to generate electricity from the sun shining directly on them and also from the sunlight reflected on the opposite side or underneath the panel or off the ground.

Bifacial Solar Panel VS. Monofacial Solar Panel

  Results and studies have shown that bifacial modules can produce additional power between 10-20% over monofacial panels. If conditions are optimized and single axis trackers adopted, the additional power can be as reach up to 30-40%.
