Vista Solar completed a 118-kW high efficiency SunPower solar power system for national builder DPR Construction. The system, which was designed, engineered and installed by Vista Solar, is expected to generate at least 158,000 kW hours of energy each year. To generate the maximum amount of power within limited roof space, Vista Solar installed high-efficiency SunPower X21/345 solar panels. Additionally, Vista Solar installed Solar Edge inverters which pair DC optimizers with each panel to produce as much power as possible, even when other panels on the roof are shaded by the adjacent buildings, as well as Silverback Solar racking for a custom design solution.
