PVNavigator has completed pilot testing a PV solar racking system on the cap of a closed Superfund landfill site in Los Angeles, CA

The work was funded by the California Energy Commission. The final report evaluated the performance of a solar racking system at the closed Operating Industries Incorporated (OII) Landfill in Monterrey Park, California a suburb in Los Angeles County located 15 miles southeast from Downtown. The system was placed at the landfill for over a year to assess its power performance and to assess its effect on the stability on the landfill cover. Geotechnical data collected during the project demonstrated that the solar racking system did not adversely affect the integrity of the landfill cover. The vegetation growth under the solar racking system was only slightly affected. No cap penetration was caused by the footings of the solar racking system. The results from this study indicated that a solar racking system on a closed large landfill is a feasible renewable alternative.
