Best solar panel angle in Espoo
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
44°collects the most energy over a year: 1011 kWh per kWp.
80°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Espoo produces the most over a year at 44°. The design month for an off-grid system is December: at 80° it makes 0.39 kWh per kWp a day, 22% more than at 44°, and costs 15% of the yearly total. Why steep panels win winter.
Off-grid solar in Espoo at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 44° (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 3,060 Wp of panels at 70°, versus 3,670 Wp at 44°. The steep array is 17% smaller for the same winter. Size your own system.
Row spacing in Espoo
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.
