Solar

Sarnafil roofing systems can support a wide variety of Solar Thermal and Solar PV solutions to provide renewable energy sources.

Rigid Solar Cell Systems

Arrays of rigid solar modules can be installed on top of Sarnafil roofing systems. However, consideration must be made as to the appropriate method of attachment and the compatibility of any free standing self-weighted systems.


To ensure the correct mounting of the rigid solar PV panels onto a Sarnafil roofing system, Sika Limited have worked with Latchways PLC to develop the Sarnafil Solar Support post. The Sarnafil Solar Support post is simply installed after the roof is complete, waterproofed with Sarnafil flashings hot air welded to the existing membrane and the solar mounting frame is then attached to the post using an M12 bolt.

For free standing self-weighted systems, consideration should be given to ensuring adequate protection of the waterproofing membrane, checking compatibility of the base material in contact with the waterproofing/protection layer and also any effects on the co-efficient of friction.

The 110 Cable Bend can also be used in conjunction with Solar systems. It is simply push fitted onto an inverted 110mm G/S or TG/TS Sarnafil Rainwater Outlet, which is fixed to the structural substrate. These two combined products allow for a neat and practical solution for accommodating the necessary Solar cabling, through the Sarnafil roof system.

Solar Thermal

Roof mounted solar thermal collectors can be installed on Sarnafil roofs to heat water. Typically, the roof mounted solar collectors will be used indirectly to heat water stored in a storage tank, via interconnecting pipes.
The water can be heated for a wide variety of uses, such as home or business and industrial uses including, swimming pools, under floor heating or energy input for space heating or cooling.

Arrays of solar thermal collectors can be installed on top of Sarnafil single ply membranes using the Sarnafil Solar Support post, developed by Sika Limited with Latchways PLC. The Sarnafil Solar Support post is simply installed after the roof is complete, waterproofed with Sarnafil flashings hot air welded to the existing membrane and the solar mounting frame is then attached to the post using an M12 bolt.
