Best solar panel angle in Piteå
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
49°collects the most energy over a year: 996 kWh per kWp.
18°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Piteå produces the most over a year at 49°. The design month for an off-grid system is December: at 18° it makes 0.02 kWh per kWp a day, 6% more than at 49°, and costs 11% of the yearly total. Why steep panels win winter.
Off-grid solar in Piteå at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 49° (year-round best).

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 76,630 Wp of panels at 70°, versus 71,720 Wp at 49°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
Row spacing in Piteå
Distance between rows of 2 m long panels (slope length) so that no row shades the next between 10:00 and 14:00 solar time on the winter solstice.
—The winter sun stays too low for rows to be shade-free; use a single row.
