Thailand's 50,000-baht
solar subsidy

Who qualifies and what can be installed

• One right per household; applicants should be the electricity account holder with a meter in their own name.
• Rooftop, ground-mounted and floating (pond) systems are all allowed, for homes whose roofs are unsuitable.
• Systems are reported at 5–10 kW, with no more than 5 kW exported.
• The utility installs a smart meter free of charge.

How the 50,000 baht is paid

• PEA's preliminary plan: once the system is installed and the utility confirms it works, the subsidy is paid directly to the installer, not to the homeowner.
• Installers must be on the utility vendor list; PEA already has more than 1,000 registered vendors. Official qualifications are not yet published.
• The homeowner pays only the remainder. The payment method is not final; some reports say the government will pay households directly.

Example cost

• PEA example: a 5 kW system costs about 140,000 baht. After the 50,000-baht subsidy, the owner pays about 90,000 baht.
• So the subsidy covers roughly a third of a 5 kW system, not most of it. Real prices depend on size, equipment and site.
• The remainder can be paid in cash or with low-interest loans from GSB, GH Bank and BAAC, repaid from sell-back income. Reports mention about 2.5% a year over about 7 years (not yet official).

How much you get for selling power

• Surplus power is bought by net billing at 2.20 baht per unit. The national energy policy council is reported to have raised the target to 10,000 MW and the contract to 20 years, but MEA's current notice still says 10 years (500 MW target), so check the new rules.
• Power you use yourself in the daytime is worth much more than power you sell, because it replaces electricity bought at the full price.
• Homeowners who install without the scheme can still claim a tax deduction of up to 200,000 baht.

The five biggest concerns people raise

• "Will I end up in debt?" Only borrow if the bill savings are bigger than the instalment. Rough example: a 5 kW system makes about 600 units a month (about 4 units per kW per day). If you use 70% of it yourself in the daytime, you save about 1,760 baht (at about 4.20 baht per unit) and sell the rest for about 400 baht, about 2,150 baht a month in total. A 90,000-baht loan at the reported 2.5% over 7 years costs about 1,170 baht a month. Every home is different, and the loan terms are not final.
• "Selling back at only 2.20 baht – how can that pay?" The value is in the power you use yourself, which replaces power bought at over 4 baht, not in what you sell. So the system should be sized to your daytime use, not oversized to sell. A home that is empty all day and uses power only at night may not be worth it, and we will say so.
• "Will installers raise prices because of the subsidy?" Always ask for an itemised quotation (panels, inverter, structure, cables, protection, labour, permits) and compare the price per kW with several installers. PEA’s example of about 140,000 baht for 5 kW is a useful reference. See our real sample quotations on the Quotation page.
• "Will the equipment fail before it pays back? Fire? Roof leaks?" Good panels usually carry a 25–30-year performance warranty and inverters 5–10 years: get the warranties in writing. Choose equipment with the Thai TIS (มอก.) standard, which is becoming mandatory for panels, and make sure DC protection and roof sealing are done properly. Cleaning once or twice a year is enough for most homes.
• "It doesn’t work at night – do I need a battery?" Not at the start. A system without a battery pays back fastest. If you have frequent power cuts or use a lot at night, choose a hybrid inverter so a battery can be added later. Batteries cost extra, so ask whether the scheme covers them.

What to do now

• Check that the electricity meter is in your name and keep your last three bills.
• Find out whether your home is single-phase or three-phase and how much power you use in the daytime.
• If you have frequent power cuts, consider a hybrid system with battery (ask whether the scheme covers batteries).
• Do not pay a deposit to anyone who claims you already have a right before the official rules and application channel are announced.
