BIS Registration (CRS) for Crystalline Silicon Terrestrial Photovoltaic (PV) modules (Si wafer-based) IS 14286 (Part 1) IS 61730 Part 1 & 2

Crystalline silicon is a form of silicon that can be either polycrystalline or monocrystalline. It is the main material used for making solar cells for photovoltaic technology. These cells are part of solar panels, which convert sunlight into solar energy. It is made up of several PV modules, and an array consists of multiple PV panels. To ensure safety, performance, and regulatory compliance, these modules must meet strict standards. This is where BIS registration for crystalline silicon PV modules is important.

 

The BIS (CRS) Registration is mandatory for Crystalline Silicon Terrestrial Photovoltaic (PV) modules (silicon wafer-based) that are sold or imported in India. This requirement ensures compliance with safety and performance standards, specifically IS 14286 (Part 1/Sec 1), IS 61730-1, and IS 61730-2. Manufacturers must obtain the certification, which involves laboratory testing conducted at BIS-approved laboratories.

 

Key Specifications of Crystalline Silicon Terrestrial Photovoltaic (PV) modules

Crystalline silicon terrestrial photovoltaic (PV) modules, also known as Si wafer-based PV modules, are a type of solar panel that uses crystalline silicon wafers to convert sunlight into electricity. The two main types of crystalline silicon PV modules are: monocrystalline and polycrystalline. The key features of the product include toughened glass with over 90% transmittance (minimum 3.2 mm thickness), resistance to potential-induced degradation (PID), a power temperature coefficient of -0.45%/°C or better, and three-layered backsheets.

 

In July 2013, the Bureau of Indian Standards (BIS) added several products under the Compulsory Registration Scheme (CRS). Crystalline Silicon Terrestrial Photovoltaic (PV) modules (Si wafer-based) were one of them. Under Scheme II of Schedule II, Crystalline Silicon Terrestrial Photovoltaic (PV) modules (Si wafer-based) get BIS registered and ensure that the product is of good quality and safe.

 

Key highlights under IS 14286 Part 1 & Sec 1, IS 61730 Part 1 & 2

1. IS 14286 (Part 1) and Sec 1 - Design Qualification

• Purpose: This standard evaluates the mechanical, thermal, and electrical requirements of the module to determine its qualification for use. The critical parameters are:
• Visual Inspection and Performance: Under Standard Test Conditions (STC).
• Environmental Durability: Test for resistance to damp heat, humidity freeze, and thermal cycle tests.
• Mechanical Strength: Tests for susceptibility to hail damage, static loads (wind & snow), and accelerated ageing.
• Electrical Safety: Insulation test, leakage current in wet conditions, and hot spot endurance.

 

2. IS 61730 Part 1 & 2 - Safety Qualification

• Part 1 Construction Requirements: Focuses on insulation, creepage distances, and clearance distances from an electrical perspective.
• Part 2 Testing Requirements: Perform safety tests for electric shock, fire hazards, and robustness.
  Requirements for Module Components: Tempered glass with a thickness of 3.2mm, quality backsheets, and UV-resistant cables.

 

3. Additional Key Technical Specifications

• Output Warranty: >90% of total power to be supplied after 10 years and >80% of total power supplied after 25 years.
• Frame: Corrosion-resistant materials, usually made of anodized aluminum.
• Terminals: UV-resistant cables and dc plug connectors. The positive terminal is male, and the negative terminal is female.

 

BIS Update of Crystalline Silicon Terrestrial Photovoltaic (PV) modules (Si wafer-based)

The Bureau of Indian Standards (BIS) mandates the Compulsory Registration Scheme (CRS) Certification for Crystalline Silicon Terrestrial PV modules (Si wafer-based) under IS 14286 and IS/IEC 61730, requiring strict safety and performance testing. A concurrent running period allows compliance with older standards until 15 February 2027, after which only the updated 2023 versions are mandatory.

 

Benefits of BIS CRS Registration for Crystalline Silicon

Advantages of obtaining BIS Registration for Crystalline Silicon Terrestrial Photovoltaic (PV) modules: 

• Legal Compliance: The BIS CRS registration is mandatory for selling PV modules in India. All producers must comply with the MNRE guidelines.
• Quality Assurance: BIS CRS registration certifies that the PV modules meet the Indian Bureau of Standards (IS 14286:2010, IS/IEC 61730) for reliability, efficiency, and safety from fires and electric shocks.
• Increased Trust in Consumers: The BIS mark assures reliability and safety to the buyer and thus increases confidence in the solar energy market.
• Competitive Advantage: Being known as a registered producer of BIS-certified PV modules provides significant market advantages over non-BIS-certified modules.
• Eligible for Government Projects: Registration is a prerequisite for bidding on public tenders, participation in government-sponsored renewable energy initiatives, and eligibility for large utility projects.

Applicable Test Parameters for Crystalline Silicon

The key test standards for crystalline silicon PV modules are provided by IS 14286 and IS 61730; these are the standards that provide for design qualification (durability) and safety of crystalline silicon terrestrial PV modules:

• Performance and Efficiency: The performance and efficiency of the module will be measured by determining the I-V characteristics under Standard Test Conditions (STC).
• Damp Heat Test: Each module will be tested for 1000 hours at 85 °C (±2oC) and 85% (±5%) relative humidity.
• Thermal Cycling: Each module will be subjected to 200 cycles of thermal cycling at temperatures of -40 °C and +85 °C.
• Humidity-Freeze Test: Each module will be subjected to 10 humidity freeze cycles from -40 °C to +85 °C.
• UV Exposure: As part of the material pre-conditioning process, each module will be subjected to ultraviolet light to evaluate the performance of the materials.
• Mechanical Load Test: Each module must meet the mechanical loading requirements for wind and snow loading (typically between 2400 and 5400 Pa).
• Hail Test: The front of each glass module will be subjected to an impact test using ice balls.
• Insulation Test: The module must demonstrate that it will not have any leakage current.
• Wet Leakage Current Test: The wet leakage current test (WLCT) of a module will be performed under wet conditions.
