Dominica bifacial solar 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.

Traditional monofacial solar panels have a direct counterpart in these newer models, with one notable exception. Bifacial panels are transparent, swapping traditional back sheets for sleek glass or apparent alternatives. This transparent back sheet allows light to pass through the panel and reach the back side, where there are also solar cells.

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.

Significant energy savings come from bifacial solar panels, especially in large-scale commercial or utility installations where adding trackers amplifies their power output. Residential installations depend on factors such as roof space, shading, and local electricity rates. Consult a solar installer for personalized advice.

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.

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.
