Soak up more sunshine on the front and back

The new Solahart Silhouette® solar panels use bifacial cells and are constructed with glass on the front and back. This next-gen technology allows them to convert both direct sunlight, and light that’s reflected off the ground or roof, into energy. Depending on the installation angle and amount of reflection, this means between 0% to 25%* more energy can be produced compared to monofacial panels.
