I live in rural Chiang Mai, 4 bedrooms with mini-split a/c units. House is solely on grid. I’m ok with the electric expense. Only run the bedroom a/c at night.
My desire is to add some kind of solar a/c unit for living room to run only during the day. It is about 7x6m with 3m ceiling. I’m figuring about 18,000 or 24,000 btu unit.
Are there units which would run off of solar only (not need the extra expense of batteries)? Any advice on unit and number and size of solar panels?
I’m not looking to tackle major power modification, just gain a little comfort during these hot days with minimal expense.
