Crystalline Silicon Terrestrial Photovoltaic (PV) Modules are widely used in solar power generation systems for residential, commercial, industrial and utility-scale applications. Because these modules operate outdoors for long periods and are exposed to electrical, thermal, mechanical and environmental stresses, compliance with applicable Indian Standards is important for product safety, reliability and performance.<\/p>\n
For manufacturers and importers supplying crystalline silicon terrestrial photovoltaic modules in India, BIS compliance under the applicable solar Quality Control Order is an important regulatory requirement.<\/p>\n
The Bureau of Indian Standards (BIS) lists Crystalline Silicon Terrestrial Photovoltaic (PV) Modules (Si wafer based)<\/strong> under its compulsory registration framework. The applicable standard family includes IS 14286<\/strong>, along with the relevant photovoltaic module safety standards.<\/p>\n The current third-revision testing framework includes IS 14286 (Part 1):2023<\/strong> and the specific requirements for crystalline silicon modules under IS 14286 (Part 1\/Sec 1):2023<\/strong>. BIS also provides uniform test report formats for these standards through its recognized laboratory system.<\/p>\n BIS CRS Certification is a conformity assessment route under which specified products are required to comply with applicable Indian Standards before they are manufactured, imported, stored for sale, sold or distributed in the Indian market, subject to the relevant regulatory order.<\/p>\n For crystalline silicon terrestrial photovoltaic modules, the BIS Scheme-II listing identifies the product category as:<\/p>\n Crystalline Silicon Terrestrial Photovoltaic (PV) Modules (Si wafer based)<\/strong><\/p>\n The BIS listing associates this product category with:<\/p>\n The original Solar Photovoltaics, Systems, Devices and Components Goods order also specifically included crystalline silicon terrestrial photovoltaic modules (Si wafer based) under IS 14286.<\/p>\n IS 14286 (Part 1\/Sec 1):2023<\/strong> covers:<\/p>\n Terrestrial Photovoltaic (PV) Modules \u2014 Design Qualification and Type Approval \u2014 Part 1-1: Special Requirements for Testing of Crystalline Silicon Photovoltaic (PV) Modules \u2014 Third Revision.<\/strong><\/p>\n The standard is associated with IEC 61215-1-1:2021<\/strong> for the corresponding special requirements for crystalline silicon photovoltaic modules. BIS’s current Uniform Test Report Format page specifically lists IS 14286 (Part 1\/Sec 1):2023 for this product category.<\/p>\n The broader IS 14286 Part 1:2023 framework covers test requirements, while Section 1 provides the special requirements applicable to crystalline silicon PV modules.<\/p>\n The Ministry of New and Renewable Energy’s Solar Systems, Devices and Components Goods Order, 2025 (Quality Control Order, 2025)<\/strong> was issued on 27 January 2025.<\/p>\n BIS’s official circular records the applicable requirements for crystalline silicon terrestrial photovoltaic modules and specifies an implementation date of:<\/p>\n 27 July 2025<\/strong><\/p>\n For crystalline silicon PV modules, the circular specifically identifies:<\/p>\n IS 14286 (Part 1):2023 \/ IEC 61215-1:2021<\/strong><\/p>\n and<\/p>\n IS 14286 (Part 1\/Sec 1):2023 \/ IEC 61215-1-1:2021<\/strong><\/p>\n with the implementation date of 27 July 2025.<\/p>\n Therefore, manufacturers and importers should ensure that their applicable PV module models comply with the currently notified requirements before placing covered products in the Indian market.<\/p>\n Crystalline silicon PV modules are solar modules manufactured using crystalline silicon-based photovoltaic cells. The cells convert sunlight into electrical energy, and multiple cells are interconnected and encapsulated to form a photovoltaic module.<\/p>\n Typical module construction can include:<\/p>\n The exact construction, materials, electrical characteristics and module design depend on the manufacturer’s product configuration.<\/p>\n The applicable BIS category covers Crystalline Silicon Terrestrial Photovoltaic (PV) Modules (Si wafer based)<\/strong>.<\/p>\n This may include different commercially manufactured crystalline silicon PV module configurations, subject to the scope and applicability of the relevant standard and QCO.<\/p>\n Before beginning certification, the exact product construction, technology, model range and intended application should be reviewed against the current BIS requirements.<\/p>\n Thin-film PV technologies such as amorphous silicon, CdTe and other thin-film technologies are addressed separately through corresponding parts or sections of the IS 14286 family. BIS’s current UTRF page separately lists Section 2 for CdTe, Section 3 for amorphous silicon and Section 4 for thin-film Cu(In,Ga)(S,Se)2-based modules.<\/p>\n Testing under the current IS 14286:2023 framework is extensive because PV modules are expected to withstand long-term outdoor operation.<\/p>\n Depending on the applicable testing program, important test areas include:<\/p>\n The module is examined for visual defects, construction issues and other conditions that could affect conformity.<\/p>\n The electrical output characteristics of the PV module are evaluated to determine maximum power under specified test conditions.<\/p>\n The insulation system of the module is evaluated to verify electrical safety.<\/p>\n The module’s electrical performance is evaluated against temperature variations.<\/p>\n PV module performance is evaluated under specified standard test conditions.<\/p>\n The module’s performance under low irradiance conditions is evaluated.<\/p>\n The module is subjected to outdoor exposure conditions as specified by the applicable testing requirements.<\/p>\n The module is evaluated for resistance to hot-spot conditions that can occur due to non-uniform illumination or related operating conditions.<\/p>\n The module is evaluated after exposure to specified ultraviolet radiation conditions.<\/p>\n The module undergoes temperature cycling to assess its ability to withstand repeated temperature changes.<\/p>\n The product is subjected to specified humidity and freezing conditions.<\/p>\n The module is exposed to elevated temperature and humidity conditions for the specified test duration.<\/p>\n Electrical terminations are evaluated for their ability to withstand the required mechanical and electrical stresses.<\/p>\n The module is tested under wet conditions to evaluate electrical safety.<\/p>\n The module is subjected to specified mechanical loading conditions.<\/p>\n The module is evaluated for resistance to specified hail impact conditions.<\/p>\n The bypass diode arrangement is evaluated according to the applicable test requirements.<\/p>\n The module may be subjected to stabilization procedures as specified by the applicable standard.<\/p>\n Where applicable under the current test program, the module is evaluated for potential induced degradation.<\/p>\n The applicable testing program may include bending tests for the module.<\/p>\n BIS LIMS currently lists these and other MQT test items for IS 14286 (Part 1\/Sec 1):2023.<\/p>\n Testing for crystalline silicon PV modules is considerably more comprehensive than ordinary product testing because the standard evaluates electrical performance, environmental durability, mechanical strength and long-term reliability.<\/p>\n BIS’s current laboratory database shows recognized laboratories offering testing against IS 14286 (Part 1\/Sec 1):2023<\/strong>.<\/p>\n For example, current BIS LIMS listings show testing charges of approximately:<\/p>\n These are laboratory testing charges shown in the BIS LIMS system and are subject to change. The actual cost can vary according to laboratory, test scope, product configuration, sample requirements and applicable testing program. Taxes and other certification-related expenses may also apply separately.<\/p>\n Therefore, manufacturers should obtain a current laboratory quotation before finalizing the certification budget.<\/p>\n The exact document set depends on the applicant, manufacturing location, product range and BIS requirements. Commonly required information and documents may include:<\/p>\n The final document requirement should be confirmed against the current BIS application procedure and the specific product configuration.<\/p>\n The general certification workflow can involve the following stages:<\/p>\n The product is reviewed to establish whether it falls within the applicable BIS\/QCO category and which standards and testing requirements apply.<\/p>\n The manufacturer identifies the models, ratings, configurations and variants intended to be covered.<\/p>\n Technical and company documents are prepared according to BIS requirements.<\/p>\n An appropriate BIS-recognized laboratory with the required scope is identified.<\/p>\n Required PV module samples are submitted for testing under the applicable IS 14286 requirements.<\/p>\n The test results and supporting technical documentation are reviewed for conformity.<\/p>\n The application and supporting documents are submitted through the applicable BIS registration process.<\/p>\n BIS examines the application and supporting documents.<\/p>\n If BIS raises observations or requires additional information, the applicant must respond appropriately.<\/p>\n After successful completion of the applicable requirements, BIS registration is processed in accordance with the applicable scheme and regulatory requirements.<\/p>\n BIS CRS\/Registration Scheme should not be treated as identical to the traditional BIS ISI Mark licensing process.<\/p>\n For a specific product, the applicable conformity assessment requirements should be checked against the current BIS scheme, QCO and product-specific requirements. Manufacturers should not assume that a traditional BIS factory inspection process automatically applies to every CRS application.<\/p>\n For solar PV modules, proper testing, documentation, manufacturing details and conformity with the applicable regulatory requirements are particularly important.<\/p>\n Once the applicable BIS registration requirements are successfully completed, the manufacturer must follow the marking and labeling requirements applicable to the product and BIS registration.<\/p>\n Product identification should be consistent with the approved product scope and applicable BIS requirements.<\/p>\n Manufacturers should ensure that model numbers, ratings, manufacturer details and other required markings are correctly represented and consistent across the product, technical documents and certification records.<\/p>\n BIS compliance may be relevant to:<\/p>\n The exact legal responsibility depends on the applicable QCO and the role of the entity in manufacturing, importing, selling or distributing the product.<\/p>\n Foreign manufacturers supplying crystalline silicon PV modules to India should review BIS requirements before shipment and commercial supply.<\/p>\n Certification planning should ideally be completed before importing covered products because testing, technical documentation and registration can require substantial time.<\/p>\n For overseas manufacturers, additional documentation and authorization requirements may apply depending on the BIS application structure and manufacturing location.<\/p>\n A proper compliance review before shipment can help reduce delays caused by incorrect documentation, unsuitable samples or incomplete testing.<\/p>\n Some common technical issues that may create difficulties during testing or certification preparation include:<\/p>\n Manufacturers should conduct a technical review before submitting samples for formal testing.<\/p>\n Qualitance India provides BIS certification consultancy support for manufacturers and businesses seeking compliance for regulated products.<\/p>\n For Crystalline Silicon Terrestrial Photovoltaic (PV) Modules (Si Wafer Based)<\/strong>, consultancy support can include:<\/p>\n The objective is to help manufacturers understand the applicable requirements and coordinate the certification process efficiently.<\/p>\n Solar PV modules are long-life electrical products that must withstand outdoor environmental conditions for extended periods.<\/p>\n A structured certification approach can help manufacturers:<\/p>\n Crystalline Silicon Terrestrial Photovoltaic (PV) Modules (Si wafer based) are covered under the applicable solar product regulatory framework. The current BIS Scheme-II listing includes this product category.<\/p>\n The current third-revision framework includes IS 14286 (Part 1):2023 and the special requirements under IS 14286 (Part 1\/Sec 1):2023 for crystalline silicon PV modules.<\/p>\n It is the third-revision standard covering special requirements for testing of crystalline silicon terrestrial photovoltaic modules.<\/p>\n The BIS circular concerning the Solar Systems, Devices and Components Goods Order, 2025 specifies 27 July 2025<\/strong> as the implementation date for the listed crystalline silicon PV module requirements.<\/p>\n No. The IS 14286:2023 framework has separate sections for different photovoltaic technologies.
