BIS Solar

BIS certifies solar modules, inverters and balance-of-system equipment to Indian Standards (IS). Learn which products need BIS registration and why it matters.

Quick answer

BIS (Bureau of Indian Standards) is India's national standards body. Under the Solar Photovoltaics, Systems, Devices and Components Goods (Requirements for Compulsory Registration) Order, 2017, solar modules, inverters and storage batteries must carry BIS registration before sale in India. DISCOMs and developers check it during procurement and approvals.

Key BIS Standards for Solar

StandardCoverage
IS 14286Crystalline PV modules (=IEC 61215)
IS/IEC 61730Module safety
IS 16221Inverter safety (=IEC 62109)
IS 16170Module performance and energy rating (=IEC 61853)
IS 16270Stationary BESS
IS 694PVC cables
IS 3043Earthing
IS 16942Lightning protection
IS 875Wind/snow loads
IS 800Steel structural

Key Takeaways

  • BIS certifies solar PV equipment to Indian Standards.
  • IS 14286 and IS/IEC 61730 (modules), IS 16221 and IS 16169 (inverters) are primary.
  • BIS certification is prerequisite for ALMM listing.
  • Required for grid-tied solar in India.
  • Equivalent to IEC standards in most cases.

Where BIS Fits in the Compliance Chain

BIS certification is an equipment-level checkpoint, not a project-level approval. A module or inverter carries a BIS mark once it has passed the relevant IS testing, but that mark by itself doesn’t get a project connected to the grid.

It feeds into two downstream steps: ALMM listing, which requires BIS-certified equipment plus factory registration before a module or inverter model can be used on government-subsidized or DCR-mandated projects, and DISCOM or CEIG verification during interconnection, where inspectors check that the modules, inverters, cables, and earthing components installed on site actually match BIS-certified specifications.

Projects that specify equipment without confirming current BIS/ALMM status often run into rejected documentation late in the permit cycle, which is why equipment selection and compliance verification are usually handled as part of the same design review rather than treated as separate steps.

BIS certification is one piece of the broader compliance picture that determines how smoothly an Indian solar project moves from design to commissioning. For a state-by-state look at how documentation gaps (including equipment certification records) affect approval timelines, see Solar Permits India: State-Wise Processing Times 2026.

Since BIS standards apply directly to the modules and inverters used on a project, Heaven Green Energy’s BIS-compliant solar modules and on-grid solar inverters illustrate what certified equipment looks like in practice, while Qbits Energy’s BIS certification process breakdown goes deeper into how manufacturers actually obtain the mark.

Frequently Asked Questions

3 commonly searched questions about BIS Solar.

Which BIS standards apply to solar equipment?
Key examples include IS 14286 for crystalline module design qualification, aligned with IEC 61215, IS/IEC 61730 for module safety, IS 16221 for inverter safety, and IS 16169 for anti-islanding tests on grid-tied inverters. Always check the latest notified list before procurement.
What is the difference between BIS and ALMM?
BIS registration confirms a product has been tested to Indian Standards. ALMM is MNRE's Approved List of Models and Manufacturers, which adds factory inspection and enlistment. Many government-backed and net-metered projects require modules to be both BIS-registered and on the ALMM list.
Who checks BIS registration on a solar project?
Developers and EPCs check it during procurement, and DISCOMs or electrical inspectors may ask for certificates during net metering or energisation approval. Missing registration can delay approvals, so collect certificates for modules and inverters before dispatch.
