Unfortunately, I don't have a "bill/usage" figure to go by as I'm just starting the build now on Samui. 70% of concrete work done. I have estimates for kW usage and amp loads though, although I will switch to gas hob to remove 6kW from that previous estimate and now will go with more extensive water collection/retention and filtration system. I will be using aac block and SCG green roof insulation (and other tips read on the forum), trying to do what I can to minimize a/c, fridge, workloads. Solar was a luxury "afterthought", which I'm assessing now. I like the idea of initially starting with 2  5kW inverters and a dedicated carport roof for the panels. Ultimately I might add this system AFTER the house is built as I don't see any great advantage in designing the system into the existing build schedule.

 

Oh...and at the house my family has rented almost 4 years, we have never used the AC. Only had coolant put in last week as we had out of country guests for 5 days and wanted the house to have working AC. However, got spoiled sleeping in a cooled down room the last few nights.....oh-oh! ????

I'm not seeing ฿7 / unit coming anytime soon.   Took 20+ yrs to go from ฿3.5 ish to not even ฿5 yet.

@Silencer

What's your PEA/MEA usage now per month, as with a proper built house, and inverter ACs, it's a good chance it will remain about the same, if using a bit more (ACs) or bit a blt less or more than present bills.

My current PEA grid electric is 3.7bht/unit.

Yes. The use of 7 baht is clearly a marketing strategy. Crossy has nailed the real world figures.

interesting, when I lived in frogland I got my usage down to circa 100kWh/month.....so that would cost me 370baht a month plus standing charge?

that's a big house with a big TV too lol.......soz I know you 'big players' are probs yawning but yeah, interesting ????
