What does Bifacial mean in solar panels?
Bifacial” in solar panels refers to a design in which the panel has photovoltaic cells on the front and back sides. This allows the panel to capture sunlight from both sides, potentially increasing total energy production. Bifacial panels can absorb light reflected from the floor or other surfaces, improving overall efficiency.
When to use bifacial solar panels?
Bifacial solar panels are often used in situations where they can benefit from reflected light or where additional energy production is desirable. They are particularly effective in installations with reflective surfaces such as white roofs or snowy environments. Bifacial panels are also suitable for ground-mounted systems with optimal spacing allowing sunlight to reach both sides of the panel.
The amount produced by a bifacial panel depends on several factors, including its design, the albedo of the surface beneath it, and the angle of sunlight. Typically, bifacial panels can generate up to 10-20% more energy than traditional monofacial panels under ideal conditions. The exact increase in production varies depending on the installation and environmental factors.
How much does a Bifacial panel produce?
“Bifaciality” refers to the characteristic of a solar panel to produce electricity on both its front and back sides. This term quantifies the percentage increase in energy production that a two-sided panel achieves compared to a standard single-sided panel. Bifacial is an important metric for assessing the added value of bifacial solar panels.
In solar installations, the “pitch” refers to the angle at which the solar panels are installed relative to the ground. The terrain is crucial to optimize the angle of exposure to the sun and maximize energy production. It is usually adjusted based on geographic location, seasonal variations and the specific needs of the solar system.
