Dinto Solar Secures Thailand’s First Mandatory TISI Certification

Dinto Solar, a global pioneer in heterojunction (HJT) photovoltaic technology, has been granted mandatory certification by the Thai Industrial Standards Institute (TISI) for its solar modules. The certification marks the first time a photovoltaic module maker worldwide has qualified under Thailand’s newly introduced safety requirements, and it is the first certification awarded to a dedicated HJT module manufacturer.

Thailand’s compulsory safety standards for crystalline silicon PV modules, codified under TIS 61730 Part 2‑2567 and aligned with IEC 61730‑2:2023, came into force on 30 October 2026. All modules imported for sale in Thailand must now comply with the applicable Thai standard and be covered by a TISI licence. The certification process evaluated Dinto Solar’s manufacturing facilities located in Longgang and Suining, China, where auditors examined quality‑management systems, production controls, supply‑chain integrity and traceability. Dinto Solar’s modules passed the assessment on the first application.

The certified product portfolio spans 33 distinct power ratings ranging from 455 W to 770 W, catering to residential rooftop installations, commercial and industrial (C&I) projects, as well as utility‑scale solar plants. The high‑efficiency HJT technology enables greater power generation per square metre, which is advantageous for sites with limited roof space. Notably, the company’s G12‑132 module features a superior temperature coefficient of –0.24 %/°C, along with butyl sealing and a coated dual‑glass construction that enhance moisture resistance and durability, supporting reliable energy yield in Thailand’s hot, humid climate.

JJ Energy Company Limited serves as Dinto Solar’s exclusive partner in Thailand and holds the necessary local import licences. Under a 2026‑2027 agreement announced in September, JJ Energy has secured an initial order of 30 MW of G12‑132 HJT modules for Thai C&I rooftop applications. The newly obtained certification enables both parties to streamline import procedures, customs clearance and distribution logistics in preparation for product delivery.

By achieving the mandatory TISI certification and establishing a local partnership with JJ Energy, Dinto Solar strengthens its market readiness in Thailand and positions itself for further expansion across Southeast Asia, aiming to deliver high‑efficiency HJT solutions that emphasize reliable performance, long‑term energy yield and customer value.
