Bifacial Solar Panels UK

Are bifacial solar panels worth it?

Bifacial solar panels generate electricity from BOTH sides — the front captures direct sunlight, the rear captures light reflected from the ground or roof surface below. Extra output: 5-30% more than standard monofacial panels (depending on installation and surface below). BEST FOR: ground-mounted systems over light surfaces (concrete, gravel, white membrane). Elevated flat roof installations with white or light roofing. NOT WORTH IT FOR: standard pitched roof installations (the rear is too close to dark tiles — minimal reflected light). COST: 10-20% more than standard panels. ROI: worthwhile for ground-mounted (5-30% gain) but marginal for roof-mounted (3-8% gain). Brands: LONGi, Trina, JA Solar all offer bifacial options.
