PV Slate
PV Slate integrates solar technology with traditional roofing aesthetics. Each unit combines toughened glass, marine-grade aluminium, and stainless steel to deliver 28W peak output while maintaining the appearance of natural slates. The system offers 25-year warranties for performance and weatherproofing, with compatibility across various roof pitches and materials. Ideal for heritage buildings and conservation areas requiring discreet renewable energy solutions.
Infinity Solar Roof
The Infinity Solar Roof provides seamless glass-and-aluminium solar coverage from ridge to gutter. Custom-manufactured to exact roof dimensions, it achieves EXT.S.AA fire certification and 25-year durability guarantees. The system incorporates powder-coated flashings and structural framing for watertight performance, suitable for new builds and complex architectural projects requiring maximum energy output without compromising design integrity.
Integrated Solar Panels
This system embeds full-sized solar panels within conventional roofing materials. Using hidden rail technology, it maintains roofline continuity while eliminating debris accumulation risks. Certified to BS 476-3 fire standards, the solution offers 25-year warranties and compatibility with clay tiles, concrete slates, and metal roofing systems across pitches between 10-45 degrees.

Report
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.

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
