Though modified bitumen is usually considered a cheap and less durable roofing solution, high quality products exist allowing the integration of photovoltaic elements for long-term clean energy generation. For turnkey projects Solar Integrated draws on two possible solutions:

• Completely roof integrated systems with solutions from UNI-SOLAR^® channel partners where UNI-SOLAR^® PV-laminates are directly attached to the final bitumen layer right after  installation. This solution is suitable for new buildings, re-roofing and newly refurbished roofs.
• The PowerTilt system, whereby the UNI-SOLAR^® PV-laminate is attached to an aluminum sandwich board installed on a light substructure. The substructure is adhered to the roof without roof penetration maintaining its watertight function and guarantee. The advantages of this system are a higher energy yield due to the optimized tilt angle and its independence of roof tilt angle – allowing installation on very flat roofs and a potentially higher packing density depending on the specifics of the individual roof. This solution is a perfect retrofit solution for existing roofs (preferably no more than three years old).
