Best solar panel angle in Sibbo
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: 999 kWh per kWp.
80°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Sibbo produces the most over a year at 44°. The design month for an off-grid system is December: at 80° it makes 0.38 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 Sibbo 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 3,180 Wp of panels at 70°, versus 3,810 Wp at 44°. The steep array is 16% smaller for the same winter. Size your own system.
Row spacing in Sibbo
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.
How Sibbo compares in Finland
Against the other 78 places in Finland with climate data, for a fixed array at its best angle.
22ndof 79 places in Finland for sunshine, shared: 2.59 peak sun hours a day on flat ground.
+2%solar energy a year compared with the average place in Finland: 999 against 983 kWh per kWp.
+5 mindaylight on the longest day, compared with Helsinki: 19 h 01 min against 18 h 56 min.
44°best year-round tilt here; across Finland it runs from 43° in Turku to 49° in Rovaniemi.
Of the 79 places in Finland, Rauma gets the most sun (2.75 peak sun hours a day) and Rovaniemi the least (2.25); Sibbo ranks joint 22nd. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 0.37 kWh a day here, against 0.26 kWh on average in Finland. The shortest day lasts 5 h 45 min, −4 min compared with Helsinki.
