Integral solution for PV plants
Photovoltaic roofs are a more and more common option to use the so-called "fifth surface" to produce renewable energy. In order to get the quickest ROI on such investment, it is key to make sure that the underlaying waterproofing system is at least as durable as the PV panels. In the case of retrofitting, lightweight solutions are a must.
Cool roof membranes are the perfect surface, as they reflect light and decrease environmental temperature. Lightweight fixing profiles are recommended to make sure that the panels are secured to the support.
Increase the efficiency of your PV installation
Figures show that solar panels perform much better on white reflective surfaces rather than on darker colours. Two reasons:
Solar panels receive part of their energy from reflection of the sun’s rays off a white roof.
RENOLIT ALKORPLAN Bright with an albedo of more than 0.8 can provide up to 3 to 4% more return than roofs with a low solar reflection.
In addition, photovoltaic modules perform better in cooler temperatures and optimally at 25°C. Every 1°C more air temperature results in a loss of 0.5% in solar panel performance.
The white cool roof technology of the Bright membrane keeps the temperature around the photovoltaic panels low and thus provides additional benefit.

RENOLIT ALKORPLAN Photovoltaic roof FAQs
Yes, the system uses hot air welded profiles that do not compromise the waterproofing layer, eliminating the risk of leaks or structural damage. It is never recommended to perforate a waterproof layer.
Very little. It’s a lightweight system that doesn’t require additional ballast, reducing structural load and associated risks, therefore it is specially recommended on existing roofs.
The thermal welding on the solar profile to the PVC membrane is a complete bonding that meets the highest requirements. Moreover, RENOLIT ALKORPLAN roofing products are fire retardant, making them very safe in case of accidental fires.
✔️ Yes. It has been tested in wind tunnels up to 200 km/h and holds technical approvals in France (Avis Technique) and Germany (DIBT).
A highly slip resistant walkway can be added to safely access the roof for maintenance.
The advanced coating of the white membrane facilitates the evacuation of water and dirt, keeping the appearance cleaner and reducing maintenance efforts.
It has been successfully installed in industrial buildings, logistic buildings, cold storages, Data centres, public buildings, sports centers, shopping malls, and private dwelling across Belgium, France, Finland, Lithuania, Spain, Switzerland, Italy, Romania and many more.
