not Thailand but Adelaide Aust. First lot only 1kw installed 2008. Second lot 5kW installed 2019. Inverter replaced under warranty only the 1kW. Still producing plenty of electrons, stinking hot 40deg day yesterday. About 30kWh.
that's a terrible thing to say, natives. This reinforces my view of using the word ex-pat, the them and us attitude. Perhaps savages is what you first had in mind before using natives. But with this much expenditure I would look at putting in solar panels. A fan is generally enough to keep cool along with the cooling powder.
