MANILA — The Department of Trade and Industry (DTI) is proposing to place solar power system products under mandatory certification requirements to ensure compliance with Philippine standards and improve product safety in the country.

In a report, it said that in a statement, Trade Secretary Maria Cristina Roque said the proposed policy aims to require solar energy systems sold locally to meet Philippine National Standards (PNS).

“As more Filipino families, businesses, and communities turn to solar power to lower electricity costs and secure a more stable energy future, it is important that the products entering the Philippine market are safe, reliable, and built to last,” Roque said.

The proposal comes amid earlier calls from Manila Electric Co. (Meralco) for tighter regulations on rooftop solar installations, citing risks of improper setups that could lead to fire incidents.

Roque said the measure is intended to protect consumers from substandard and unsafe solar products that may fail prematurely or pose hazards to homes and establishments.

“The proposed mandatory product certification also aims to prevent the Philippines from becoming a dumping ground for substandard solar products rejected by other countries,” she said.

She added that the government wants to ensure consumers get durable and properly tested solar systems that can deliver long-term savings.

“By upholding clear quality standards, the government seeks to give Filipinos greater confidence that the solar systems they invest in are durable, properly tested, and capable of delivering real savings over the long term,” she said.

The DTI clarified that the proposal will recognize test reports from accredited and recognized laboratories and will not cover installation or mounting of solar energy systems.

“It also does not cover the installation or mounting of solar energy systems,” Roque said.

“As the country continues its transition toward cleaner and more affordable energy, ensuring the quality and safety of solar products is critical to protecting consumers, strengthening trust in renewable energy, and supporting the sustainable growth of the solar industry in the Philippines,” she added.

The agency said it remains open to public input on the proposed regulation, with stakeholders allowed to submit comments until July 25, 2026 through OASFTG@dti.gov.ph.
