Best solar panel angle in Kaukauna
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
38°collects the most energy over a year: 1382 kWh per kWp.
73°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Kaukauna produces the most over a year at 38°. The design month for an off-grid system is December: at 73° it makes 2.41 kWh per kWp a day, 18% more than at 38°, and costs 15% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 490 Wp of panels at 70°, versus 580 Wp at 38°. The steep array is 15% smaller for the same winter. Size your own system.
