OP is estimated up 50kWh a day, 1500kWh a month = ฿7500 PEA bill ฿600k / ฿7500 = 80 months = 6.66 yrs ROI 👍 If 40kWh a day = 8.33 yrs ROI For 20 ROI, your PEA bill is only ฿2500 a month (<530kWh) Yes, of course. I realized my error after I'd posted when it was too late to edit. I was waiting for someone to correct me. Thanks for the revised figures. 2 Link to comment Share on other sites More sharing options...

The fans all run from solar. Better to get acclimatised to the Thai weather IMHO. Ok , that explains it . Yes then the units sound prob right . It also gives maybe some people some understanding back , as they might do the same but then get a much larger bill since they are running the airco 24/7 (or all night or anyway more hours then you).
