India is preparing a major upgrade to rooftop solar safety standards through a new framework tentatively called the Solar Safety Code 2026. Industry sources told SolSetu that MNRE is reviewing a unified set of installation and safety rules that would apply to all rooftops across the country.

The move comes as rooftop solar adoption accelerates, but safety inconsistencies remain common due to varied installer skills, wiring practices, and component selection.

What the Solar Safety Code May Include

Draft discussions indicate the code may introduce:

• Standardized wiring thickness and conduit rules
• Mandatory DC isolators and surge protection devices
• Approved rooftop structural load guidelines
• Compulsory fire-safe cable routing
• Standard earthing resistance requirements
• Digital safety certification for each new installation

This would become the first national system ensuring uniform installation quality across states.

Why a Safety Code Is Needed Now

As rooftop installations grow, several DISCOMs and state nodal agencies have reported safety gaps caused by rapid market expansion. A unified safety code could significantly reduce electrical risks, inverter failures, and rooftop fire incidents.

An MNRE official told SolSetu, “A safety code is essential for preparing India’s rooftops for the next decade of solar growth.”

Who Will Be Affected?

The code will apply to:

• Residential rooftop systems
• Commercial buildings
• Housing societies & apartments
• Industrial rooftop setups

Installers may require updated training and recertification under the new framework.

Expected Rollout

The Solar Safety Code could be released in mid-2026, with a 6–12 month transition window for installers to adopt the new standards.

SolSetu will continue tracking this development and publish updates as MNRE refines the guidelines.
