As of early 2026, electrical safety rules and compliance requirements for solar power plants in India are primarily governed by the Central Electricity Authority (CEA), the Bureau of Indian Standards (BIS), and the Ministry of New and Renewable Energy (MNRE)

 As of early 2026, electrical safety rules and compliance requirements for solar power plants in India are primarily governed by the Central Electricity Authority (CEA), the Bureau of Indian Standards (BIS), and the Ministry of New and Renewable Energy (MNRE). The key compliance deadline is June 1, 2026, for using indigenously produced solar components (cells)

Here are the critical electrical safety rules and compliance requirements mandated for 2026:

1. Mandatory Solar Component Compliance (From June 1, 2026) 

• ALMM for Cells (List-II): From June 1, 2026, all solar PV modules used in projects (including government-backed schemes, net-metering, and open access) must source their solar cells from ALMM List-II (Approved List of Models & Manufacturers).
• Mandatory ALMM for Modules: Continued requirement to use modules from ALMM List-I.
• Exemption Deadline: Projects with bid submission dates before the issuance of this order are exempt, even if commissioned after June 1, 2026.
• Behind-the-Meter Exemption: Projects for captive consumption commissioned before June 1, 2026, are exempt from the ALMM cell requirement. 

2. Mandatory Inverter Standards (From Jan 1, 2026) 

• BEE Labeling & Efficiency: All grid-connected solar inverters up to 100 kW must comply with mandatory Minimum Efficiency Performance Standards (MEPS) and carry a BEE (Bureau of Energy Efficiency) endorsement label.
• Safety Standard: Inverters must be BIS certified under IS 16221-2:2015.
• Extension for Large Inverters: For inverters above 200 kW, the BIS compliance deadline is extended to June 30, 2026. 

3. Electrical Safety Standards and Technical Requirements

• BIS Standards: Solar modules must meet updated BIS safety standards IS/IEC 61730-1:2023 and IS/IEC 61730-2:2023.
• Anti-Islanding Protection: Grid-tied inverters must possess mandatory anti-islanding protection to prevent power export during grid failures.
• Earthing & Protection: Strict compliance with CEA guidelines for grounding/earthing and surge protection to prevent fire.
• RFID Tagging: Mandatory RFID tags on all PV modules to ensure traceability and quality.
• Arc Flash Safety: Implementing arc-resistant switchgear and regular, mandated safety audits.

4. Regulatory and Safety Audits 

• Safety Audits: Mandatory regular electrical safety audits for solar and wind plants (for certain capacity thresholds).
• Fire Safety: For BESS (Battery Energy Storage Systems),, fire safety audits are mandatory, including ensuring that battery containers are placed at least 7.5 meters from other structures.
• Third-Party Audits: Independent fire safety audits are required for battery systems, with reports submitted to the Electrical Inspector. 

Summary Table for 2026 Compliance

Component/Aspect	Requirement	Effective Date
Solar Cells	Must be from ALMM List-II	1 June 2026
Inverters (<=100kW)	BEE Labeling & IS 16221-2:2015	1 Jan 2026
Inverters (>200kW)	BIS Compliance Deadline	30 June 2026
Solar Modules	IS/IEC 61730:2023 (Updated)	Ongoing (Transition)
Safety Audit	Mandatory Electrical/Fire Audit	Ongoing

Non-compliance with these orders can lead to penalties under the Bureau of Indian Standards Act, 2016, and potential suspension or blacklisting of the project.
