An Affordable Free Span Solar System


P4P Energy, LLC — short for Power for the Planet — recently completed the installation of its first, cable-suspended free span solar system in the parking lot of the headquarters building for REM Eyewear in Sun Valley, California.  Designed and patented by P4P Energy and TenSol Power, the array spans 107 feet on low-cost cables and provides shade for cars parked below.  It's expected to generate roughly 40,877 kWh of electricity per year. 

The floating photovoltaic system differs from a traditional solar installation in that it doesn't require excessive columns and foundation work.  Rather, with low-cost cables, hundreds of panels can span a distance of up to 200 feet, depending on the project and location. 

P4P Energy envisions free standing solar systems in a variety of applications, including on spare land, on the top of buildings, or over roads or aqueducts.  The applications almost seem endless, and the system can withstand winds of up to 85 miles per hour.  Not to mention, P4P Energy claims their system is one of the lowest (if not the lowest) cost system for solar in a parking lot.

    That’s a great idea! I wonder how it would work in snowy areas like Colorado?

      I’m in NY- maybe the snow would fall off between the panels?
      But do the sways mean they are not as efficient?

    Nice. Now this is cost-efficient. Check out this site to find out more about solar power installations:
