Compliance window

Focusing on compliance acceptance and retrofit value: the questions behind every project decision

For EPCs, investors and owners, a rapid shutdown solution affects not only project acceptance, but also retrofit cost, O&M efficiency and long-term asset safety.

National Standard Timeline

Oct 2025

Mandatory national standard programme issued (plan 20256235-Q-339), setting out electrical, fire and mechanical safety requirements for modules.

Mar 2026

Approval draft opened for public comment; engineering teams begin evaluating technology routes early.

25 May 2026

Safety Requirements for Photovoltaic Modules formally published, with a 12-month transition period — we are inside that window now.

1 Jun 2027

The mandatory standard takes effect. Projects upgraded during the transition avoid a last-minute rush.

Industry Pain Points = Project Decision Pain Points

Fire / MaintenanceRapidly disconnect module-side voltage in high-voltage risk scenarios to protect personnel.
Construction & RetrofitConventional PLC / RS485 wiring and expansion are costly on complex sites.
Acceptance & O&MAfter handover the plant still needs long-term monitoring, traceability and maintainability.
