Total Solar Resource Fraction (TSRF)

Total Solar Resource Fraction is a solar industry term that simply means the total sunlight an evaluated area will collect throughout a given year. TSRF accounts for things such as tree shading, roof tilt, and roof orientation. An area with 100% TSRF represents an area that will get all of the possible sunlight available without anything obstructing its view of direct sunlight.
