A unique integrated solution providing robust, durable bitumen waterproofing and the production of clean efficient electrical energy within a single flat roof system configuration.
Excel® Solar PV Flex combines Excel® high-performance reinforced bitumen waterproofing membranes, manufactured with the patented Alpa® polymeric binder with fully bonded Solar PV Flex (CIGS) flexible photovoltaic modules. Excel Solar PV Flex modules are prefabricated with a self-adhesive under surface that adheres directly to the Excel Solar waterproofing membrane without the requirement for heat or additional mechanical restraint.
Excel Solar PV Flex is a flexible polymer encapsulated thin-film solar module based on advanced CIGS (Copper Indium Gallium Selenide) technology. The photovoltaic modules are lightweight (2.9 kg/m²), shatterproof, hail resistant, compatible with Excel® 25 Solar bitumen waterproofing membrane and being flexible are suitable for all roof shapes with no requirement for orientation, plinths, or ventilation. Increased energy output is achieved when compared to rigid panel systems especially in low level light or indirect light conditions.
The Excel Solar waterproofing system is designed for installation in either a multi or single layer application using hot air welding, torch-on or mechanical fastening techniques. With exceptional ageing characteristics and excellent bond strength, Excel Solar has been technologically developed to be flexible and durable and is suitable for use on all new build and refurbishment Solar PV projects.
Excel Solar PV Flex modules use flame free, self-adhesive application techniques. This eliminates any need for penetration of the Excel® waterproofing system during installation and greatly simplifies installation on roofs of all shapes and sizes. The modules can simply be bonded to curved surfaces, enabling solar power generation on roofs where traditional rigid silicon panels are not suitable.
Axter Universal Fixing Points (UFPs) are fully compatible with Excel® systems and should be installed to support cable trays for PV cabling. Prefabricated cable penetration units should also be installed to ensure the waterproofing system integrity is maintained at all times.
Excel® Solar PV Flex modules are supplied with a manufacturer’s linear electrical energy production guarantee and combined product performance guarantee of 20 years.
Excel® Solar PV Flex systems are manufactured in full compliance with EN 61646 and EN 61730 and meet all relevant British and harmonised European standards. They are compliant with BS EN 62446 Grid Connected Photovoltaics and BS EN 61853-1 Defining Solar Photovoltaic Power.
Excel® Solar PV Flex waterproofing system is British Board of Agrément (BBA) certified Certificate No 94/3037, compliant with BS 6229: 2018 - Flat Roofs with continuously supported flexible waterproof coverings – Code of Practice, CE Marked and accepted by all third party building warranty providers such as the LABC and the NHBC.
