Protan Solar Roofs
Ready for onroof energy sources
The right membrane type and quality are selected on the basis of whether the panels are photovoltaic or thermal. The panels can be integrated on the roof or free standing.
Normally the membrane is fastened mechanically when a photovoltaic (PV) or thermal panel array is going to be put on the roof. Protan SE membrane reinforced with polyester is therefore used for these purposes.
The right colour for the job
PV panels work most efficiently when they are kept cool. Light coloured surfaces usually reflect sunlight better than dark colours. Our white Protan Cool Roof and light grey Protan SE membranes are therefore primarily used when there are plans to install PV panels on the roof. Protan Cool Roof has some of the best solar reflectance values on the market for this type of product and makes an optimum contribution to a Protan Solar Roof system with PV panels.
Thermal solar panels convert solar energy into heat which is used to heat water. This type of solar panel works more efficiently the hotter it is. It is therefore an advantage to have dark surfaces that absorb as much of the heat from the sun as possible. For this purpose we recommend our black or dark grey Protan SE membrane.
