PV Slate
PV Slate integrates solar technology with traditional slate aesthetics, offering a discreet, lightweight solution for roofs. Each unit replaces four natural slates, providing 28W of power while maintaining weatherproofing. Backed by a 25-year warranty, it suits heritage buildings and conservation areas, blending seamlessly with natural slates. The system reduces carbon emissions and enhances property value through its elegant design and durability.
Infinity Solar Roof
Infinity delivers a seamless glass and aluminium solar roof with high power output. Designed for full roof coverage, it combines structural framing with waterproof solar panels, achieving fire safety ratings of EXT.S.AA. Ideal for new builds and retrofits, it offsets traditional roofing costs and offers custom sizing for hips, valleys, and unique architectural features.
Integrated Solar Panels
Our Integrated Solar Panels merge with conventional roofing materials like tiles or slates, eliminating the need for over-roof mounting. Using marine-grade aluminium and stainless steel, the system ensures longevity and aerodynamic efficiency. It avoids debris buildup, provides bird-proofing, and maintains roof integrity while offering a low-profile, aesthetically pleasing solar solution.

My personal experience with GB-Sol has been first class. Didn't want PV Panels that were sourced in China, wanted a UK product and the service I recieved from them throughout the ordering, intsalation and after sales period was excellent. Would highly recommend.

Report
We installed PV Slates manufactured by GB Sol in early 2019. One of the great advantages of using a small local manufacturer was the support we received during the design stage and installation. Before placing our order we were able to visit GB Sol to see the product in person and work with one of their engineers to ensure that the system would meet our requirements. When it came to installation an employee of GB Sol came to site to instruct us in the installation process. The managing director even popped in when passing by to make sure everything was working out! We are very pleased with our

Having worked with Mark and the GB Sol team over several projects now, we hope to continue our successful collaborative partnership moving into future developments; their input into projects from inception scheme proposals & viability all the way through the process to their hard working & dedicated site installation team makes them a pleasure to work with. More than happy to recommend!

Get the distinct impression that they cant be bothered. I ask for something so simple it was untrue, more information on a few products! Get an email back saying someone will be in touch 5-7 days! Then when they finally do get in touch they dont even read your original request!
Edit: thanks for the follow up mark. Maybe next time abit more effort in your part wouldnt go amiss as you did accept responsibility in your email. I give credit where its due and 1 star reviews where its also due. All I was looking for was information on your canopys but it didnt happen. Kind regards
