New Wattstone 15 Degree Mounting Package: Installation and Features Explained
In this video, Boris introduces the brand new Wattstone 15° mounting package. This system offers improved weight distribution and easy installation in both east-west and south orientations. Boris walks through the steps of the installation, including the use of construction protection mats and module clamps to securely install the Wattstones. He also explains the benefits of the new east-west connection system and the increased wind resistance up to wind load zone IV.
New product: Wind deflector for Wattstone 15° PV mounting
We are pleased to introduce our latest product: the wind deflector for the Wattstone 15° PV mounting system. This wind deflector is an important addition to your photovoltaic system, specifically designed to enhance the safety of your PV system in strong winds.
What is the purpose of the wind deflector?
The wind deflector serves to direct the wind around the PV modules. This reduces the wind load on the modules and the entire structure, which is particularly advantageous during strong gusts and hurricanes. This measure significantly reduces the risk of damage from high wind speeds and increases the stability of your system.
Benefits of the Wind Deflector
- Improved Safety: Protection against wind damage through effective wind diversion.
- Increased Stability: Reduction of the wind load on the PV modules and the substructure.
- Durability: Longer preservation of the structural integrity of your PV system even under extreme weather conditions.

Stability, reliability, and durability – that is WATTSTONE
Set up in just 5 minutes
Traditional PV ground mount systems usually require anchoring, gluing, or ballasting on the roof. Often, concrete slabs are used as ballast. With the robust concrete bases from WATTSTONE as the foundation for the ground structure, these steps are completely eliminated.
ConcretePV - stable bases made of fine concrete for your PV modules
Discover the ease of installation by avoiding the drilling of the roof structure and instead using our high-quality L-stones with integrated M8 threads. No more worries about unsightly and complicated installations - with our L-stones, securing solar panels and cables becomes a breeze.
