Best solar panel angle in Tromsø
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
48°collects the most energy over a year: 772 kWh per kWp.
87°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Tromsø produces the most over a year at 48°. The design month for an off-grid system is January: at 87° it makes 0.00 kWh per kWp a day, and costs 17% of the yearly total. Why steep panels win winter.
Off-grid solar in Tromsø at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 48° (year-round best).

Sizing example. To run a 1 kWh-per-day load through January on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 117,960 Wp of panels at 70°, versus 117,960 Wp at 48°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
Row spacing in Tromsø
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 Tromsø compares in Norway
Against the other 39 places in Norway with climate data, for a fixed array at its best angle.
39thof 40 places in Norway for sunshine, shared: 1.95 peak sun hours a day on flat ground.
−20%solar energy a year compared with the average place in Norway: 772 against 967 kWh per kWp.
+5 h 10 mindaylight on the longest day, compared with Oslo: 24 h (midnight sun) against 18 h 50 min.
48°best year-round tilt here; across Norway it runs from 42° in Bergen to 48° in Tromsø.
Of the 40 places in Norway, Grimstad gets the most sun (2.78 peak sun hours a day) and Tromsø and one other place the least (1.95); Tromsø ranks joint 39th. In its darkest month, January, 1 kWp of off-grid panels at 70° makes 0.00 kWh a day here, against 0.41 kWh on average in Norway. The shortest day lasts 0 h (polar night), −5 h 54 min compared with Oslo.
