I have a question for you regarding installation of electricity in a new house I am intending to build later this year.

How can I contact you for advice ?

Thanks

The cheapest 24 SEER I can find with a quick search is 34k Baht (DAIKIN FTKZ12VV2S) the 22k Baht units are around 17-18 SEER.

Be sure to check the SEER for your particular model, as they often quote the best SEER for the entire size range.

So with an assumed saving of 1,500 units per annum (6,750 Baht @ 4.5 per unit). That's a payback of 5 years on energy usage.

In a perfect world, using data provided but the marketing department.

Adding 330W solar panels at 2,890 Baht a piece (I already have the inverter) would generate roughly 400 units (1,800 Baht @ 4.5 per unit) per year per panel. Payback of 1.6 years on energy generation.

Given your experience this is a reliable number.

Purely on energy savings there's only one winner, but ...

But at ten years old, the air-con can last another ten years or ten minutes. Probably last another five anyway. bot

 

Combine both in a single project and you can get the payback for both down to three years....
