The Cabinet has approved a tax deduction for households installing solar rooftop systems, allowing individuals to claim up to 200,000 baht per year, including VAT. The measure aims to encourage clean energy adoption in residential areas and will be effective from the date of publication in the Royal Gazette until December 2028.

 

Energy Minister Attaphol Rerkpiboon announced the decision on 25 November 2025, highlighting the government’s push for renewable energy use at the household level. This initiative is part of broader efforts to reduce carbon emissions and promote sustainable energy solutions across Thailand.

 

The tax deduction covers the total cost of installing solar rooftop systems, providing an immediate financial incentive for homeowners. Experts say this could significantly increase solar adoption rates and reduce household electricity costs over time. Consumers are encouraged to plan installations before the scheme expires in 2028 to maximise benefits.

 

Amarin reported that officials noted that the scheme applies to individual taxpayers and is intended to complement other national clean energy policies. The government also hopes that greater household adoption of solar energy will contribute to the country’s long-term energy security and sustainability goals.

 

Key Takeaways

 

• Homeowners can claim up to 200,000 baht per year for solar rooftop installations.

• The deduction includes VAT and applies until December 2028.

• The policy aims to promote clean energy and reduce household electricity costs.

THat is a good move, but where do you find qualified installers? and besides that you need permission form the local PEA too

You don't need permission from PEA but it's wise to get register the installation with them once complete, which costs about 12K thb.

Most people in Thailand do not pay tax so the 200,000-tax rebate will not be claimed by them.

What are you on about? Millions upon millions of Thai's pay tax. Yes we have some who dont pay but they would not be interested in a large solar system as its not necessary for them. For the middle to upper income Thai's this will be a big break. Many already are installing solar systems and this will only encourage more to do so. Many newer mubans around Bangkok already come with this solar feature.  We do have a strong and relentless sun here.

I doubt low-income earners would be considering a solar installation any ways!

75% of THais don't pay tax or don't even fill in a tax form

i resent subsidizing, and this one like so many other, is transferring wealth from poor to rich

Good move for sure!

There are plenty of companies that can install, some are really good. it's not that hard to install thou, the trick part is the final details in the switches and cabling to ensure it will last. In electrical systems, the details are the most important.

 

i'll get a new 5kW setup next year but wont be able to do tax deductions, not possible on the 15% flat BOI tax 😄 

 

I plan to do it just to boost my voltage up, here in the country side it's kinda weak, cant even use 7kW EV charger... have to stick with 2kW.

You're correct, but the end beneficiaries are richer than you think: the owners of data centers.  This is a sneaky way to avoid directly increasing electric bills (see the US) to feed the energy hungry data centers. Get home owners to build the dispersed infrastructure and fund it with tax credits.  Solar panels wont come close to meeting the needs of data centers, but it does delay the inevitable price hikes to PEA customers.

 

Thailand's coming digital gulag will require a lot of power and water.  More solar means having to construct fewer new power plants. 

This is a tax break for the rich. 

I have a solar system but am not allowed to send excess power back to the grid. Giving credit for power sent to the grid would be a much better incentive than this tax credit IMO

I have been trying to find the link that says only 16%  of Thai's pay any income tax, in my rural area, that would be about right.

We have a few homes with solar panels on the roof in my area, most are farmers, the guy who fits them, did our solar system, pumping water in to our pond from a local river.

He said to make it pay you needed to have an electric bill, before installation of about 9000 baht/month.
