Indian & IEC Standards for Solar
The standards that actually get cited in Indian solar specifications, tenders, and quality disputes — each explained in one plain sentence, with what it governs. Use it to read a technical specification, or to check what a vendor is claiming compliance with.

| IS 14286 | Crystalline silicon PV modules — design qualification | Solar modules | Mandatory BIS design-qualification standard for modules sold in India. Aligned with IEC 61215. |
| IS/IEC 61730 | PV module safety qualification | Solar modules | Electrical and fire safety construction requirements. Paired with IS 14286 on module labels. |
| IEC 61215 | Design qualification and type approval | Solar modules | International performance and durability testing — thermal cycling, damp heat, mechanical load. |
| IEC 61853 | Module performance and energy rating | Solar modules | Tests output across real-world temperature and irradiance combinations, not just STC. |
| IEC 62804 | PID test methods | Solar modules | Verifies resistance to potential induced degradation — relevant in hot, humid Indian coasts. |
| IEC 62109 | Safety of power converters for PV systems | Inverters | Core inverter safety standard covering electrical, thermal, and protective design. |
| IS 694 | PVC insulated cables up to 1100 V | Cabling | Indian cable standard applied to AC and general wiring in rooftop systems. |
| IEC 62930 | Electric cables for photovoltaic systems | DC cabling | Purpose-made solar DC cable standard — UV resistance, double insulation, 25-year outdoor life. |
| IS 3043 | Code of practice for earthing | Earthing | Governs earth-pit design and resistance. Practice targets low, stable earth resistance across seasons. |
| IS 875 (Part 3) | Design loads — wind loads | Structures | Wind-load design basis for mounting structures. Coastal and cyclone zones carry the highest design speeds. |
| IS 4759 | Hot dip zinc coatings on structural steel | Structures | Galvanising standard. Solar practice calls for ~80 micron coating; thin coating is a common shortcut. |
| CEA Regulations | Technical standards for connectivity of distributed generation | Grid connection | Central Electricity Authority rules governing how rooftop systems may connect to the DISCOM grid. |

How to Read This Data
- Standards are periodically revised. Always confirm the current part and year of issue when writing a specification or tender.
- A vendor claiming compliance should be able to produce the test certificate naming the standard and the specific model tested.
