Best solar panel angle in Orleans
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
26°collects the most energy over a year: 1414 kWh per kWp.
49°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Orleans produces the most over a year at 26°. The design month for an off-grid system is June: at 49° it makes 3.40 kWh per kWp a day, 11% more than at 26°, and costs 7% 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 530 Wp of panels at 70°, versus 390 Wp at 26°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
