Whether a commercial or residential system, a solar system is attached to the roof by means of either ballast or minimal roof penetration. The following picture shows the first SunPower “Helix” system in NYC: a passive dual-tilt ballasted system that allows for enhanced solar production.
NYC Department of Building code requirements may constrain the size of a rooftop solar system. By lifting the PV system several feet above the roof, we are typically able to increase production by 25% or more. The following photo shows a state-of-the-art “canopy” system with virtually no roof penetration.
It is possible that a solar system can become part of the curtain wall of a building. This picture shows one such system, the first of its kind in the Bronx. This project has been selected by SunPower as one of the five best commercial systems in the country for 2016.
As an authorized SunPower dealer, we are able to offer the “best in class” with respect to design and installation of solar carport systems. The following design drawing shows a system over 1 MW in size.
