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 7,330 Wp of panels at 70°, versus 8,790 Wp at 45°. The steep array is 17% smaller for the same winter. Size your own system.

Row spacing in Trondheim

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.

29thof 40 places in Norway for sunshine, shared: 2.29 peak sun hours a day on flat ground.

−8%solar energy a year compared with the average place in Norway: 889 against 967 kWh per kWp.

+1 h 46 mindaylight on the longest day, compared with Oslo: 20 h 36 min against 18 h 50 min.

45°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); Trondheim ranks joint 29th. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 0.16 kWh a day here, against 0.41 kWh on average in Norway. The shortest day lasts 4 h 30 min, −1 h 24 min compared with Oslo.
