  • It is often the simplest, cheapest and most theft-proof option to install PV modules on the roof of a home. In this case, typically the angle of the existing roof is used as the tilt angle for the PV module. An 17° latitude, an PV module with a tilt angle of 7° will only produce an estimated 2.1% less than a PV module with a tilt angle of 17°.[1]
  • Mounting systems are frequently build that enable users to change the angle of the PV modules through the course of the year to maximize production at higher latitudes. The standard array angle adjustment is +15° at the fall solstice and -15° at the spring solstice. At 41° latitude, a system that is adjusted at the two solstices will produce an estimated 6% more than a system that is at a fixed 41° tilt. This additional energy can be crucial in the winter.[1]
