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 6,750 Wp of panels at 70°, versus 7,980 Wp at 46°. The steep array is 15% smaller for the same winter. Size your own system.

Row spacing in Siilinjärvi

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.
