Photovoltaic (PV) cables are special cables used in solar power systems to connect solar panels, inverters, and other electrical components. These cables are designed to handle sunlight, heat, moisture, and harsh weather conditions while safely carrying electricity. Good quality PV cables are important for the safety, efficiency, and long life of solar systems.
To maintain quality and safety standards, the Bureau of Indian Standards (BIS) introduced IS 17293:2020 for photovoltaic cables. This standard defines the requirements and testing process for PV cables used in solar applications. BIS certification ensures that the cables are reliable, safe, and suitable for use in solar energy systems in India.
Why BIS Certification is Mandatory for Photovoltaic Cables
- Mandatory by Law – BIS certification is required for photovoltaic (PV) cables under the standard before they can be sold in India.
- Avoids Legal Penalties – Selling non-certified PV cables may lead to fines, product seizure, and legal action under BIS regulations.
- Builds Customer Trust – The BIS certification mark assures customers that the cables are reliable and suitable for solar applications.
- Supports Smooth Market Entry – BIS-certified PV cables can be easily supplied and used in solar projects across India without compliance issues.
What is IS 17293:2020?
This is an Indian standard issued by the Bureau of Indian Standards (BIS) for
photovoltaic (PV) cables used in solar power systems. It defines the safety, quality,
and performance requirements that these cables must meet before being sold in
India.
This standard helps ensure that PV cables:
- Safely carry electricity in solar systems
- Resist heat, sunlight, and harsh weather conditions
- Reduce the risk of electrical faults and fire hazards
- Provide long-lasting and reliable performance
- Meet required quality and safety tests
BIS Testing Requirements for Solar Cables
To ensure safety, durability, and proper performance, photovoltaic (PV) cables are
tested as per standard requirements before BIS certification is granted. These tests
check the cable’s electrical safety, insulation quality, resistance to heat, and
performance in solar conditions.
How to Get BIS Approval for Solar Cables

To obtain BIS certification for these cables under IS 17293:2020, manufacturers
must follow the BIS certification process. The main steps include:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for required safety and performance parameters, including electric strength, insulation resistance, and mechanical integrity.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: Officials from the Bureau of Indian Standards (BIS) conduct an inspection of the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: After successful verification of all requirements, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Once the license is granted, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
