Commercial Racking & Wind Deflection

The commercial racking system is designed for a flat roof. The modules are mounted on the ballasted racks. Ballast means cement blocks (ballasts) are used. The problem with many roofs is the weight required to “fully ballast” (counterweight) a large array of PV modules (solar panels). Sun Smart™ provides a combination of ballast and wind-deflectors, which significantly reduces the number of cement ballasts and corresponding weight on a flat roof. The difference is over 7% more expense for wind-deflectors, but the benefit is the lower weight. The weight savings per square foot is over 42% for a typical installation for a 7% difference in cost.
