KEI Solar announced the availability of the Eulektra ALVA Solar Racking System for North American solar installers and commercial projects. Developed in Germany, the Eulektra solar racking system has been extensively tested and installed through Europe and is now available for U.S. solar installations.
Designed for flat roofs, the lightweight (just 22 lbs per square meter (10.7 sq. ft.) Eulektra system is easy to install. It is wind resistant without requiring additional weights and offers better power generation results than competing panel installation technologies.
Because of its compact design, solar panels can be mounted closer together than with other mounting technologies (One-fifth of an inch apart!). This enables installers to install more panels on a roof and/or provide additional roof space for other rooftop machinery and systems.
“Because the Eulektra system does not require any roof penetration, there is much less concern about creating roof leaks that are difficult and expensive to repair,” says Jens Kautzor, CEO of KEI Solar. “Simple to set-up, the ALVA system consists of interconnected adjustable aluminum pieces that can be snapped together and be quickly installed by using only a power screwdriver and pliers. No special training or expertise is required”.
After the entire system is laid out on the roof and interconnected with the provided bracing, the aluminum structure is then secured to the building by using steel cables that are anchored in the building walls and mounted into the cable channels of the ALVA system. This installation method guarantees that the roof cladding remains completely undamaged. No more leaks.
Here are some images that demonstrate the install.
The ALVA system is resistant to swirling winds and has been hurricane wind speed tested. It also requires less maintenance than other systems. Considering that aluminum expands and contracts as the temperature changes, the ALVA system is flexible, protecting panels against breakage caused by rapid temperature changes. To ensure good rain drainage, the system can be elevated with provided 10cm by 10cm installations pads.
