Bifacial solar panels in desert environments can generate between 10% and 30% of their total output from the back face, thanks to the region’s naturally high reflectivity. Light-colored sand and dry soil reflect more sunlight onto the rear of the panels, boosting efficiency, with white sand reflecting up to 50% of sunlight. Elevating the panels and optimizing their tilt further enhances this effect, while wider row spacing prevents shading and allows more light to reach the back. Studies in high-albedo deserts like Chile’s Atacama and Israel’s Negev show that under ideal conditions, bifacial gains can exceed 20%, making these panels particularly well-suited for sun-drenched landscapes.
