BIS Registration of Solar Panels
India is rapidly transitioning toward renewable energy, and solar power plays a leading role in this clean energy revolution. To ensure that all solar equipment used in the country meets the highest standards of safety and efficiency, the Bureau of Indian Standards (BIS) has made certification mandatory for solar photovoltaic (PV) modules.
The BIS Registration for Solar Panels guarantees that the products comply with Indian standards, ensuring their durability, safety, and quality. For manufacturers, importers, and traders, obtaining BIS certification is not just a legal requirement but a mark of reliability in the Indian solar market.
What is BIS Registration?
The Bureau of Indian Standards (BIS) operates under the Ministry of Consumer Affairs, Food & Public Distribution, Government of India. BIS certification ensures that products meet specific quality and safety benchmarks defined under Indian Standards (IS).
For the solar industry, BIS registration falls under the Compulsory Registration Scheme (CRS). It mandates that solar panels, PV modules, and related products must be tested and approved before being sold or imported in India.
Why is BIS Certification Important for Solar Panels?
As India continues to promote renewable energy under government initiatives like “Make in India” and “Atmanirbhar Bharat”, the solar industry has expanded exponentially. However, with rising demand, many substandard and low-efficiency solar modules also entered the market.
To protect consumers and project developers, the Ministry of New and Renewable Energy (MNRE) made BIS certification mandatory. It ensures that every panel installed in India meets strict safety and performance standards, thereby increasing efficiency and reducing project risks.
Applicable BIS Standards for Solar PV Modules
The following Indian Standards are applicable for BIS certification of solar panels:
IS 14286:2019 – Crystalline silicon terrestrial photovoltaic (PV) modules – Design qualification and type approval.
IS/IEC 61730-1:2017 & IS/IEC 61730-2:2017 – Safety qualification for photovoltaic (PV) modules – Part 1: Construction requirements and Part 2: Testing requirements.
IS 16077:2013 – Thin-film terrestrial photovoltaic (PV) modules – Design qualification and type approval.
Each solar panel model must undergo testing according to these standards in a BIS-recognized laboratory in India.
Who Must Obtain BIS Registration for Solar Panels?
BIS certification is mandatory for all categories involved in the solar product lifecycle:
Indian manufacturers producing solar panels domestically.
Foreign manufacturers exporting solar panels to India.
Importers and distributors marketing foreign-made solar modules in India.
Foreign companies must appoint an Authorized Indian Representative (AIR) to apply on their behalf.
Benefits of BIS Registration for Solar Panels
Obtaining BIS registration is not just about meeting regulatory requirements; it also brings several strategic advantages:
Legal Authorization – Only BIS-certified solar panels can be legally sold or imported in India.
Enhanced Market Credibility – Certification enhances brand trust and consumer confidence.
Participation in Government Projects – BIS-certified manufacturers are eligible for MNRE tenders and large-scale solar projects.
Quality Assurance – Ensures that panels perform safely and efficiently under various conditions.
Reduced Maintenance Costs – Certified products have longer lifespans and lower failure rates.
Competitive Advantage – BIS mark helps brands stand out in a competitive solar market.
Step-by-Step Process for BIS Registration
The BIS registration process for solar panels involves several stages. Here’s a detailed breakdown:
1. Testing of Product Samples
The manufacturer sends samples of the solar panel to a BIS-approved testing laboratory in India. The samples are tested according to relevant IS standards.
2. Preparation of Documents
Documents such as the manufacturing license, factory address proof, test report, and technical details of the product are prepared.
3. Online Application Submission
The manufacturer (or AIR) submits the BIS registration application on the BIS online portal under the Compulsory Registration Scheme (CRS).
4. Review by BIS Officials
BIS authorities review the application and test reports to verify compliance with prescribed standards.
5. Grant of BIS Registration Certificate
Upon successful review, the BIS authority issues a registration certificate to the manufacturer. The manufacturer can then use the Standard Mark (BIS logo) on their solar panels.
Documents Required for BIS Certification
Below are the commonly required documents for BIS registration of solar panels:
Application form under CRS
Test report from BIS-recognized laboratory
Copy of factory license or incorporation certificate
Product specifications and datasheets
Manufacturing process flow chart
Brand authorization letter (if applicable)
Details of Authorized Indian Representative (for foreign manufacturers)
Undertaking of conformity to IS standards
Validity and Renewal of BIS Registration
The BIS registration certificate remains valid for two years from the date of issue. After expiry, manufacturers can renew their registration by submitting updated documents and proof of continued compliance with BIS standards. Timely renewal ensures uninterrupted business and compliance with MNRE guidelines.
Penalties for Non-Compliance
Selling, importing, or distributing solar panels without valid BIS certification is illegal in India. Non-compliance may result in:
Product seizure by authorities
Financial penalties
Ban on imports or manufacturing
Legal action under BIS Act, 2016
Hence, manufacturers must ensure that every product batch remains BIS certified before being sold in the market.
How BIS Certification Promotes Quality in the Solar Sector
The enforcement of BIS registration has significantly improved product quality in the Indian solar industry. Certified panels are tested for durability, thermal performance, safety, and long-term efficiency, ensuring consistent energy generation.
This helps project developers achieve better performance ratios and reduces maintenance costs over time. Ultimately, BIS certification supports India’s goal of achieving net-zero emissions and sustainable energy independence.
FAQs on BIS Registration for Solar Panels
Q1. Is BIS certification mandatory for solar PV modules in India?
Yes, BIS certification is mandatory for all solar panels manufactured, sold, or imported in India under MNRE guidelines.
Q2. How long does the BIS registration process take?
Generally, the process takes 6–8 weeks, depending on testing timelines and document verification.
Q3. Can a foreign company apply for BIS registration?
Yes, foreign manufacturers can apply through an Authorized Indian Representative (AIR) who acts on their behalf in India.
Q4. What is the cost of BIS certification for solar panels?
The cost varies based on the product type, testing fees, and government charges. Consulting a BIS certification expert helps estimate the total expense.
Q5. Is the BIS certificate valid for all models?
