Note

Solar Panel: Changed from 420W to 200W - correctly sized for 66W system (KOOMPI 36W + 3× Deco 10W each).

Power Sizing Explanation

Daily Power Budget

  • KOOMPI Mini: 36W × 8 hours = 288Wh
  • Deco X60 (3 units): 30W × 8 hours = 240Wh
  • Total: 66W × 8 hours = 528Wh/day

Solar Panel Sizing

  • Cambodia sun hours: 5 hours/day average
  • Daily need: 528Wh
  • Panel output needed: 528Wh ÷ (5 hours × 0.75 efficiency) = 140W minimum
  • With safety margin: 140W × 1.4 = 196W → 200W panel ✓

Battery Sizing

  • Capacity needed: 528Wh × 2 days = 1,056Wh
  • Battery: 12V × 100Ah = 1,200Wh
  • Autonomy: 1,200Wh ÷ 528Wh = 2.3 days ✓

Result: 200W panel + 100Ah battery is perfectly sized!
