DERBISOLAR® is a waterproofing membrane with integrated flexible photovoltaic a-Si cells which convert sunlight into electricity. The DERBISOLAR system is suitable for: - Non-accessible (or only accessible for maintenance), flat or sloped (min. 3%) roofs, with no water stagnation zones. - New constructions - Renovation of roofs with new roofing or compatible membranes. DERBISOLAR consists of a bitumen waterproofing membrane DERBISOLAR BASE from the DERBIGUM® product range and photovoltaic laminates PVL-68, PVL-136 or PVL-144 from UNISOLAR®.
