We have three houses, but I would only be looking to install solar power on the main house, as the other two have very minimal electricity usage. The main house is a reasonably large bungalow. We have a fridge-freezer, a separate freestanding freezer outside, electric gates, two large televisions, and air conditioning in one bedroom, a washing machine, and the usual scattering of fans around the house. Our average monthly electricity bill for the main house is typically between 2,500 and 4,000 baht. TBF, it usually hangs around 3200 baht to 3500 baht. Given this level of consumption, would a solar installation be a worthwhile investment? Moreover, are solar installation standards and after-sales support now well established in Isaan? Our local PEA has been advertising systems starting at around 240,000 baht, and I would be interested to know whether this represents good value and what sort of payback period I could realistically expect.
