Peak Sun Hours (PSH): The Technician’s Shortcut
Calculating solar energy production using raw irradiance data requires complex integration (Calculus). However, field technicians use a powerful simplified metric called Peak…
-
The Enemies of Generation: Shading and Poor Orientation
The conversion efficiency of a PV system is fundamentally governed by the magnitude and quality of incident radiation. However, two external…
