Wattstone 10°V2 Fine Concrete Ballast PV Mounting System for Flat Roof

Wattstone 10°V2 Fine Concrete Ballast PV Mounting System for Flat Roof

Robust concrete base as PV substructure for solar modules on flat roofs – wind tunnel certified, no roof penetration and flexibly suitable for east-west, south and sail installations.

The Wattstone V2 with 10 degree tilt is a high-quality fine concrete base for easy and fast mounting of PV modules on flat roofs – without any roof penetration and secured purely by ballasting. The PV modules are simply placed on the surface using protective mats and secured with PV module clamps to the integrated M8 threaded inserts made of V2A stainless steel. With the revised V2 generation, installers benefit from significantly faster installation, an optimised clamping area and new integrated boreholes for wind deflectors and micro inverters. For neat PV cable management, the Wattstone Cable Clips Set is the perfect companion.

What's new with the Wattstone 10°V2?

The V2 generation brings three key improvements over its predecessor: Firstly, the optimised clamping area enables up to 70% faster installation compared to the previous version. Secondly, 10 mm boreholes for the optional mounting of micro inverters, cable ducts and east-west connectors or wind deflectors (for south-facing installations) are already integrated. Thirdly, the flexible system combination allows connection with the Wattstone 10°XL – either as a sail system (horizontal modules) or as an XL system (vertical modules) for large-format PV modules.

Who is the Wattstone system suitable for?

Thanks to its system flexibility, it is suitable for virtually any application – whether east-west, south or sail installation, whether small balcony power stations from a single module or large residential and commercial systems. With the free wind load calculator and the practical set configurator, larger systems can be planned with ease. The matching accessories for all configurations are available in our shop. For any further questions about products or system design, please do not hesitate to contact us.

Safety Instructions:

1. Installation by Professionals: The installation should only be carried out by qualified and authorized professionals.
2. Wear Protective Equipment: When handling PV modules, use appropriate protective equipment such as gloves and safety glasses.
3. Components must operate within the technical specifications listed in their data sheets.
4. Use only manufacturer-approved accessories.
5. Do not install components if they are physically damaged or equipped with damaged or substandard cables or connectors.
6. No Work Under Voltage: Perform installation or maintenance work only when the system is de-energized.
7. Do not apply an external voltage source to a module or a string with components.
8. Protection from External Influences: Install protective conduits and cables in a way that shields them from UV radiation, rodents, and mechanical damage.
9. Protection from Moisture and Dirt: Store and install accessories in dry and clean locations to prevent damage from moisture or contamination.
10. Regular Inspection: Inspections and maintenance should be carried out regularly to detect potential damage or signs of aging at an early stage.
