Low-pitch metal roofs are often the most ideal location to mount solar panels. This can help reduce the cost of mounting and thus the overall cost of the system.
To the left, a commercial 25kW system is having rows of panels mounted. In this system, inverters which convert the DC power from the panels into AC power usable by the business, are located under the panels and are known as "micro" inverters. Micro inverters offer the greatest safety and highest production yields of all major types of inverters. The typical warranty for a microinverter is 25 years!
When there is available space, solar panels are also commonly mounted on the ground when an ideal roof location does not exist, or when very large systems are being installed. Ground arrays produce slightly more power as the solar installer can orient the panels in the most ideal location and direction. Panels also tend to operate at lower temperatures, increasing production.
