BANGKOK, THAILAND – Thailand’s cabinet approved a major tax bonus for household solar systems, offering annual deductions of up to 200,000 baht including VAT.
Historic cabinet decision on rooftop solar
Energy Minister Attaphol Rerkpiboon announced the decision on 25 November, describing it as a historic step to expand clean power in residential areas. The policy aimed to bring clean energy into households across the country.
“The measure is intended to promote the introduction of clean energy in residential areas.”
said Attaphol Rerkpiboon, energy minister.
Full installation costs now tax-deductible
The tax deduction covered the entire installation costs of rooftop solar systems, creating an immediate financial incentive for homeowners. All expenses for rooftop solar installation were deductible, up to 200,000 baht per year, including value-added tax.
The programme applied from its publication in the Royal Gazette until December 2028, giving property owners about three years to access the full benefit.
Experts expect surge in solar demand
Energy specialists predicted a sharp rise in solar adoption under the scheme.
“This could significantly increase solar adoption rates.”
said unnamed experts.
They forecast that demand for rooftop systems would grow rapidly as the tax savings and lower power bills took effect.
Double benefit for household finances
Households stood to gain twice: they could save on taxes while also cutting their electricity bills. Over time, energy costs were expected to fall noticeably, while Thailand became less dependent on fossil fuels. The government hoped that wider use of solar power would create a domino effect and strengthen national energy security.
Deadline pressures and eligibility
Officials urged consumers to plan installations promptly, as support would end in late 2028 and delaying could mean missing out. Broadcaster Amarin reported that the programme applied to individual taxpayers, making it particularly suitable for owners of houses and apartments. According to the report, Thailand sent a clear signal in favour of sustainable energy policy, with what it described as a “green revolution” starting on the nation’s rooftops.
Part of Thailand’s wider energy strategy
The solar incentive formed only one element of Thailand’s broader energy master plan and complemented other national clean energy policies. The overarching goals were to cut CO2 emissions and to increase energy independence. The shift toward renewable energy was to be rewarded, positioning Thailand as a regional frontrunner in Southeast Asia.
Key points homeowners should note
Experts stressed that homeowners effectively had a three-year window to benefit fully from the maximum support and advised swift planning. Installations needed to be carried out by certified specialist companies for taxpayers to obtain the full bonus. Observers expected Thailand’s rooftops to change markedly in the coming years, with solar panels becoming a new standard feature across residential areas.
