If you PEA bills are that low, it wouldn't cost you ฿600k for a system.

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.

I only use Aircon occasionally, at the moment 1-2hrs/day as it's very hot, normally not at all. 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).

my usage/production is 20-43kw per day and my 300k DIY setup is 2 x 5K inverters. 28 x 330w pannels and 30kw batteries. My electric bill used to be around 3000/month upto 4500/month, now its 38-1xx bt/month

By electric bill use to be from 38 bath to 1xx bath a month. So i use 0 to 5 units per month from grid.

Getting nearer to installing Solar

We will check what we are using in the day and maybe do without a battery and just run 2 air cons at night (2 bedrooms)

If we get extra solar panels for 4 air cons in the day and swimming pool pump to run in the day this might be the way to go.
