Energy Ministry proposes new law to simplify solar rooftop installation

The Energy Ministry is preparing to propose a new draft law aimed at encouraging people to install solar rooftop systems on their homes.

Deputy government spokeswoman Sasikarn Wattanachan explained that the draft act to promote and support the use of solar power aims to make it easier and faster for people to install solar rooftops, by reducing procedures, cutting costs and sustainably lowering electricity bills.

The draft legislation is currently open for public consultation, which will close on Friday, May 30. Citizens are invited to share their opinions via the website www.law.go.th, the government’s central platform for collecting feedback on proposed laws.Sasikarn noted that at present, installing a solar rooftop system in Thailand involves a complex, cumbersome process with high costs, especially as approval is required from five different government agencies..

The new draft law is therefore designed to “remove all barriers,” with key measures including:


Changing from requiring a “permit” to a “notification,” to speed up installation, with government agencies having no authority to retrospectively revoke approvals.
Supporting access to funding, such as tax incentives and low-interest loans.
Establishing a one-stop service centre to provide advice and support to the public and private sectors.
Setting national standards to ensure installations are safe and verifiable.
Drafting a central law to genuinely protect citizens’ rights to use clean energy in their own homes.


Sasikarn added that once the consultation period ends in May, the draft law will be submitted to the Cabinet for consideration in June, and will then proceed to Parliament in July 2025.

“The government reiterates that solar energy is no longer something distant, but a power available to every citizen to help reduce electricity costs, enhance life stability, and create sustainable development for the grassroots economy,” she said.

“We invite the public to share their views by May 30, 2025. Every voice today is a crucial driving force that can propel the country towards a sustainable and fair energy future.”
