For the first time, a solar racking manufacturer tested its ballast-only roof-mounted racking system on U.C. Berkeley's Pacific Earthquake Engineering Research Center (PEER) shaking table in Richmond, Calif., and it appears to have passed with flying colors.
The March 5 test "provided us with information on how our roof mounting system acted [when] not connected to a roof," said Mike Williams, senior vice president-engineering for SunLink, San Rafael, Calif. The product "acted like we thought it would," he added.
