Best solar panel angle in Calliaqua
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
14°collects the most energy over a year: 1714 kWh per kWp.
11°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Calliaqua produces the most over a year at 14°. The design month for an off-grid system is June: at 11° it makes 4.36 kWh per kWp a day, 2% more than at 14°, and costs 0% of the yearly total. Why steep panels win winter.
Off-grid solar in Calliaqua at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 14° (year-round best).

Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 820 Wp of panels at 70°, versus 280 Wp at 14°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
