PV Installations on larger buildings such as manufacturing facilities, apartments, parking garages, offices and retail structures provide supplemental power to support energy needs.
PV installations on commercial or industrial buildings tend to be larger than those found on residential buildings due to the larger available space on the roofs and availability of capital to invest in the system.
With various types of roofing found across the world, and the majority of roofs found in the developed world being flat, racking systems are used to install the solar modules. This allows for modules to be correctly positioned and angled for optimal performance.
