Best solar panel angle in Viby
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
42°collects the most energy over a year: 1073 kWh per kWp.
76°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Viby produces the most over a year at 42°. The design month for an off-grid system is December: at 76° it makes 0.77 kWh per kWp a day, 20% more than at 42°, and costs 14% of the yearly total. Why steep panels win winter.
