Solar PV Flex

The CIGS module carries a 5 year product warranty against material defect and a 25 year linear power output warranty - 80% of the nominal power (STC). As part of a BIPV (Building Integrated Photovoltaic) system, please see the waterproofing product guarantee documents for the full guarantee information.

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® 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 in low level light or indirect light conditions.

The Solar PV Flex with an Excel® waterproofing system is designed for installation in either a multi or single layer application using torch-on techniques. With exceptional ageing characteristics and excellent bond strength, Axter's Solar PV Flex has been technologically developed to be flexible and durable and is suitable for use on all new build and refurbishment Solar PV projects.

The application technique for Solar PV Flex 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.

Prefabricated cable penetration units should also be installed to ensure the waterproofing system integrity is maintained at all times.

We will offer a full bespoke design pack including a 3D model covering the yield calculation, wind uplift calculation (where required) and a modelled output of the system. We can also show you an accurate cost saving if we are provided with the consumption figures.

We will supply you with a full system, which includes the recommendation of an approved Axter installation partner.

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, and B Roof (T4) tested.
