Ballasted mounting systems use weight to hold down the racking and modules instead of attaching them directly to the site surface.
The first ballasted system was Powerlight’s successful Powerguard system in 2002. Following that was the first tilted ballasted mounting – the Schott ES system. Since then, ballasted systems have seen a steady rise in popularity, and now dominate the industry due to unwillingness to penetrate the surface of their solar sites.
Solstice mounting was introduced to the industry in 2007 with the aim of driving down the costs of mounting and labor by simplifying the design and install process. Solstice was the first system widely adopted for use on landfills and brownfields.
