Crystalline Silicon Solar Panels (PV Modules) BIS Certification

Who needs it

Any manufacturer making crystalline silicon solar panels (PV modules) for the Indian market, and any importer bringing it in, needs the product covered by a valid BIS registration (CRS). Registration is granted to the manufacturer for a specific factory, brand and models. Overseas manufacturers must appoint an Authorised Indian Representative to apply and hold the registration in India.

Without it, the goods cannot be manufactured, imported, sold, distributed or stored for sale. Contravening Section 17 of the BIS Act, 2016 can lead to imprisonment of up to two years, or a fine of at least ₹2 lakh (₹5 lakh for repeat contraventions) that can reach ten times the value of the goods, or both.

3. Apply on the CRS portal with the test report, factory and brand documents
4. BIS review and grant of the R-number registration
