Best solar panel angle in Delfzijl
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
39°collects the most energy over a year: 1050 kWh per kWp.
73°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Delfzijl produces the most over a year at 39°. The design month for an off-grid system is December: at 73° it makes 0.98 kWh per kWp a day, 19% more than at 39°, and costs 14% of the yearly total. Why steep panels win winter.
