Best solar panel angle in Vaasa
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
45°collects the most energy over a year: 1027 kWh per kWp.
67°gives the most in the darkest month — the one an off-grid system is sized for.

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 15,410 Wp of panels at 70°, versus 16,080 Wp at 45°. The steep array is 4% smaller for the same winter. Size your own system.
Row spacing in Vaasa
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.
