A fixed array in Mae Sot produces the most over a year at 20°. The design month for an off-grid system is July: at 1° it makes 3.08 kWh per kWp a day, 7% more than at 20°, and costs 4% 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 800 Wp of panels at 70°, versus 410 Wp at 20°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

294thof 295 places in Thailand for sunshine: 4.76 peak sun hours a day on flat ground.
−4%solar energy a year compared with the average place in Thailand: 1,453 against 1,509 kWh per kWp.
+11 mindaylight on the longest day, compared with Bangkok: 13 h 08 min against 12 h 56 min.
20°best year-round tilt here; across Thailand it runs from 4° in Narathiwat to 23° in Mae Chan.
Of the 295 places in Thailand, Bangkok and 7 other places get the most sun (5.23 peak sun hours a day) and Mae Ramat the least (4.74); Mae Sot ranks 294th. In its darkest month, July, 1 kWp of off-grid panels at 70° makes 1.48 kWh a day here, against 1.53 kWh on average in Thailand. The shortest day lasts 11 h 08 min, −11 min compared with Bangkok.
