The solar energy industry is growing rapidly in India. Solar PV modules are widely used in residential rooftops, commercial buildings, industrial facilities, and large-scale solar power projects. To maintain product quality, safety, and performance, the Government of India has made BIS certification mandatory for applicable solar photovoltaic modules.

BIS Certification for Solar PV Modules ensures that solar panels meet the required Indian Standards before they are manufactured, imported, distributed, or sold in the Indian market. The certification process involves product testing, technical documentation, and registration with the Bureau of Indian Standards (BIS).

What Is BIS CRS Registration for Solar PV Modules?

BIS CRS Registration for Solar PV Modules is a regulatory approval that confirms solar panels comply with the applicable Indian Standards. The Bureau of Indian Standards operates the Compulsory Registration Scheme (CRS) under Scheme II for covered solar products.

Manufacturers must get their products tested at BIS-recognised laboratories and complete the registration process before placing applicable products in the Indian market.

This certification helps verify that solar modules meet specified performance, construction, and electrical safety requirements. It also helps manufacturers establish product credibility and meet government compliance requirements.

Why Is BIS Certification Mandatory for Solar Panels?

Solar panels operate outdoors under changing weather conditions, including high temperatures, humidity, rain, and mechanical pressure. Poor-quality modules may experience performance issues, electrical failures, or reduced durability.

BIS certification helps ensure that solar PV modules meet established quality and safety requirements.

The main benefits include:

• Ensures compliance with applicable Indian Standards.

• Improves product reliability and safety.

• Supports legal market entry in India.

• Builds confidence among customers and distributors.

• Helps manufacturers meet applicable Quality Control Orders.

• Reduces the risk of regulatory action against non-compliant products.

Applicable Indian Standards for Solar PV Modules

Solar module manufacturers must identify the correct Indian Standards according to their product technology and design.

Important standards include:

These standards cover different aspects of solar module performance and safety. Manufacturers should verify the latest applicable editions and BIS transition requirements before applying.

BIS CRS Registration Process for Solar PV Modules

The BIS registration process involves several steps. Manufacturers should prepare their products and documents before submitting an application.

1. Identify Applicable Standards: Determine the relevant Indian Standards based on the solar module type and technology.

2. Product Testing: Submit representative product samples to a BIS-recognised laboratory for the required performance and safety tests.

3. Prepare Documents: Arrange technical specifications, product details, factory information, and other supporting documents.

4. Online Application: Submit the registration application through the BIS online portal with the required information.

5. Application Verification: BIS reviews the submitted application, technical documents, and laboratory test reports.

6. Registration Approval: After successful verification, BIS grants registration with a unique registration number.

7. Use of Standard Mark: The manufacturer can use the applicable BIS Standard Mark with the assigned registration number according to the relevant requirements.

Documents Required for BIS Certification

Manufacturers need to prepare the necessary documents to complete the BIS CRS registration process.

Commonly required documents include:

• Company registration certificate.

• Manufacturing unit address proof.

• Factory details and contact information.

• Product technical specifications.

• Complete product description and model details.

• Bill of Materials (BOM).

• Authorised signatory details.

• Product photographs and labels.

• Laboratory test reports.

• Trademark or brand authorisation documents, where applicable.

The exact documentation may vary depending on the product category and application requirements.

BIS Certification for Foreign Solar Panel Manufacturers

Foreign manufacturers planning to sell solar PV modules in India must also comply with applicable BIS requirements. They need to appoint an Authorised Indian Representative (AIR) to handle the CRS application on their behalf.

The manufacturer remains the applicant and registration holder. The product must undergo the required testing at a BIS-recognised laboratory, and the necessary technical documents must be submitted.

It is important to understand that solar PV modules follow the CRS route under Scheme II rather than the Foreign Manufacturers Certification Scheme (FMCS).

BIS Certification and MNRE Compliance

Apart from BIS registration, solar module manufacturers should understand the requirements of the Ministry of New and Renewable Energy (MNRE).

The Solar Systems, Devices and Components Goods Order, 2025 introduced updated compliance requirements for solar PV modules, inverters, and storage batteries. It includes minimum module efficiency requirements of 18% for monocrystalline and thin-film modules and 17% for polycrystalline modules.

Manufacturers supplying government-supported solar projects should also check the applicable Approved List of Models and Manufacturers (ALMM) requirements. BIS certification and ALMM listing are separate compliance requirements.

Conclusion

BIS Certification for Solar PV Modules is essential for manufacturers and importers dealing with applicable solar products in India. It ensures that solar modules meet the required quality, performance, and safety standards.

Understanding the CRS registration process, applicable Indian Standards, documentation, and MNRE requirements can help businesses avoid compliance delays.
