40 M AY / J U N E 2 0 1 8 PRODUCTS TO WATCH Energy dense options for C&I rooftops SunModo SunBeam As a permanent part of the building and roof struc- ture, the SunBeam system eliminates any abrasions, moss build up and need of system removal for roof repair or re-roofing. In addition, it provides shading of HVAC equipment, increasing efficiency and faster temperature response. Twenty-year warranty. Material: High-grade aluminum and 304 stainless steel hardware. Anchor-only attachment. How it maximizes energ y density: The SunBeam system elevates above obstructions such as HVAC, pipes and vents. By spanning over roof obstructions such as HVAC, pipes and vents, the system takes full advantage of the available roof surface thereby maximizing the PV system size. The system can be easily adjusted to account for the multiple roof pitches on site. Everest Solar D Dome R² The D Dome R² system is an east/west commercial flat roof solution. The third generation of this product is now rail-less with only five major components and minimal hardware. It sits at a fixed 10-degree pitch and allows for 3.5-in. inter-row spacing. Twenty-year war- ranty. Material: Aluminum, ballast with attachment option- al. The ballast blocks sit under the panels. How it maximizes energ y density: Everest Solar Systems believes east/west systems are more efficient south of the tropic of cancer. First, an east/west system practically eliminates inter-row spacing which allows more modules on the roof, thus increasing module den- sity. On one internal study, Everest compared a the production of a 10-degree south-facing system with its east/west system in southern California at different azi- muths. The south-facing fit 88 modules and had a 14 percent decrease in at the 225-degree azimuth. The D Dome R² system reached 108 modules in the same space and had less than 0.1 percent change between all azi- muth angles.
