What is a bifacial solar panel?

A bifacial solar panel is a PV module with two active sides. Instead of a white or black back sheet on the rear side, it has another layer of glass that protects solar cells. It often doesn’t have a frame. How do bifacial solar panels work? The front side of a bifacial panel works just like any normal panel would do.

Are bifacial solar panels better than monofacial panels?

The technology behind solar panels continues to evolve and improve. Manufacturers are now able to produce bifacial panels, which feature energy-producing solar cells on both sides of the panel. With two faces capable of absorbing sunlight, bifacial solar panels can be more efficient than traditional monofacial panels – if used appropriately.

Are bifacial solar panels a good investment?

And, as we’ll discuss, bifacial panels are also more expensive than traditional single-face panels, which can affect the breakeven point of your investment. Bifacial solar panels can capture light energy on both sides of the panel, whereas monofacial panels (AKA traditional solar panels) only absorb sunlight on the front.

Are bifacial solar panels suitable for rooftop installations?

Bifacial solar panels are not suitable for rooftop installations but may work well with residential ground-mounted solar systems. The ideal use case for bifacial solar panels is in commercial and utility-scale solar installations.

Are bifacial panels more energy efficient?

With more surface area available to absorb sunlight, bifacial panels are generally more efficient than traditional monofacial panels. For example, a study by solar panel manufacturer LONGi found that bifacial panels produced 11% more energy than standard panels as part of a ground-mounted installation.

What are bifacial panels?

Bifacial panels have a slim profile compared to monofacial panels. They often have minimal framing and are enclosed in a thin, transparent layer of either a dual-glass design or a clear back sheet. Mounting systems for bifacial panels are also designed differently to maximize energy capture from both sides.
