A fixed array in Sinmak produces the most over a year at 37°. The design month for an off-grid system is July: at 31° it makes 3.13 kWh per kWp a day, 3% more than at 37°, and costs 0% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through July on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 560 Wp of panels at 70°, versus 390 Wp at 37°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Sinmak compares in North Korea
Against the other 96 places in North Korea with climate data, for a fixed array at its best angle.
53rdof 97 places in North Korea for sunshine, shared: 3.86 peak sun hours a day on flat ground.
−2%solar energy a year compared with the average place in North Korea: 1,395 against 1,424 kWh per kWp.
−4 mindaylight on the longest day, compared with Pyongyang: 14 h 51 min against 14 h 55 min.
37°best year-round tilt here; across North Korea it runs from 34° in Ongjin to 44° in Namyang-nodongjagu.
Of the 97 places in North Korea, Sinp’o and one other place get the most sun (3.91 peak sun hours a day) and Ŏrang and one other place the least (3.70); Sinmak ranks joint 53rd. In its darkest month, July, 1 kWp of off-grid panels at 70° makes 2.09 kWh a day here, against 2.28 kWh on average in North Korea. The shortest day lasts 9 h 29 min, +4 min compared with Pyongyang.
