Adaptable. Grounded. The SFUSA°Ground Mountsystem is the optimal solution for residential and light commercial solar projects. By custom designing and manufacturing components in-house, Solar Foundations' structure fits and functions together seamlessly, installs in for less time and with greater strength. The highest quality materials such as high- grade steel fully galvanized in accordance with ASTM standards and high -strength aluminum alloys for our panel support rails are utilized for long-term durability. Designed to withstand high snow and wind areas, the UL 2703 classified system has an expected lifespan that exceeds multiple panel lifecycles. Thus, Solar Foundations' product maximizes the residual investment ofyour ground mount structure. Solar Foundations' patented rail design offers a simple connection detail between the panel support rail and the horizontal support beams. The patented telescopic design of the SFUSA Wind Brace allows quick and easily adaptable length changes to match installation conditions where significant adjustability is required. A two -man crew can typically install up to about a 25kW residential structure in a single day. SFUSA has developed processes and equipment that permits the installation of our patent pending ground screws in any soil conditions including solid rock. :f Allows for mounting panels in four-, five- or six -high in landscape orientation and can be adapted to custom configurations ./ Durable design enables any wind speed and snow load 10° to 40' tilt with multiple inter -row spacing options Compatible with a wide range of modules Pile verification reportavailable after the installation has been completed ✓r 25 year guarantee against failure Let us simplify your ground mount structure process.
