Thin Film Terrestrial Photovoltaic Modules — including amorphous silicon (a-Si), copper indium gallium selenide (CIGS/CiGs), and cadmium telluride (CdTe) modules — require mandatory BIS CRS Registration before they can be manufactured for sale, imported, or distributed in India. Registration is issued by the Ministry of New and Renewable Energy (MNRE) under the BIS Compulsory Registration Scheme (CRS). The applicable Indian Standards are IS 16077:2013/IEC 61646:2008 (thin-film PV module performance) and IS/IEC 61730 (Part 1):2004 (construction requirements) and IS/IEC 61730 (Part 2):2004 (testing requirements for PV module safety). The registration is manufacturer-specific, site-specific, and brand-specific. Foreign manufacturers must appoint an Authorised Indian Representative (AIR). Non-compliance is an offence under the BIS Act, 2016.
Thin-film photovoltaic modules represent one of the most technically innovative segments of the global solar energy industry. Unlike the dominant crystalline silicon panels made from individual wafers, thin-film modules are manufactured by depositing extremely thin photovoltaic semiconductor layers — measured in micrometres — onto glass, metal, or flexible substrates. This manufacturing approach enables lower material usage, more uniform large-area deposition, better performance in high-temperature and diffuse-light conditions, and unique form factors that open up architectural and land-constrained deployment opportunities unavailable to silicon wafer-based panels.
India's thin-film PV module market is growing at approximately 12–15% annually, driven by utility-scale solar projects requiring large-area deployment, building-integrated photovoltaics (BIPV), land-constrained commercial rooftop installations where temperature performance matters, and government incentives for renewable energy adoption. As thin-film technologies gain ground in India, BIS CRS Registration — issued by MNRE — is the mandatory compliance gateway every manufacturer and importer must cross before entering this market.

Why BIS CRS Registration Is Mandatory for Thin Film PV Modules
Thin-film photovoltaic modules are electrical generating devices that produce DC electricity at significant voltages under solar irradiance. They are installed on rooftops, in open-field solar farms, and on building facades — typically for operational lifetimes of 25 years or more. Inadequate module construction, insufficient insulation between the photovoltaic cell layer and accessible surfaces, or substandard junction box safety can create electric shock, fire, or arc-flash hazards for installers, maintenance personnel, and building occupants. India's BIS CRS Registration framework — administered by MNRE for solar energy products — ensures every thin-film module sold in the Indian market meets defined safety and performance standards before installation.

BIS CRS registration under IS/IEC 61730 verifies that thin-film modules meet insulation, dielectric strength, and grounding requirements — protecting installers, maintenance workers, and building occupants from electric shock and arc-flash hazards across a 25-year module operational lifetime.
BIS CRS registration under IS 16077/IEC 61646 verifies that thin-film modules perform to their rated specifications — confirming that power output, efficiency, and degradation performance under Indian operating conditions match the manufacturer's declared data.
Without valid BIS CRS registration, no thin-film PV module can legally be imported, sold, or installed in India. Customs clearance requires BIS certification. MNRE-funded projects and government procurement programmes require BIS-registered modules as a mandatory qualification condition.
India's 500 GW renewable energy target by 2030 is driving the largest solar procurement programme in the world. BIS registration opens access to this programme — government tenders, SECI auctions, and DISCOM procurement all require BIS-certified modules, making registration a commercial as well as legal imperative.
Three Thin-Film Technologies Covered by BIS CRS Registration
BIS CRS Registration under IS 16077:2013/IEC 61646:2008 and IS/IEC 61730 applies to all three principal commercial thin-film photovoltaic technologies — each with distinct semiconductor materials, manufacturing processes, performance characteristics, and deployment advantages in the Indian market.
The original commercial thin-film technology — silicon deposited in a disordered (amorphous) structure on glass or flexible substrates. Lower efficiency than crystalline silicon but excellent performance in low-light and high-temperature conditions. Well-suited to Indian climate zones with high ambient temperatures. Requires BIS CRS under IS 16077/IEC 61646 and IS/IEC 61730.
The highest-efficiency commercial thin-film technology — a quaternary compound semiconductor deposited on glass or metal foil. Efficiencies approaching monocrystalline silicon with better temperature performance. Used in premium rooftop, BIPV, and utility-scale applications in India. Full BIS CRS testing under IS 16077/IEC 61646 and IS/IEC 61730 is required.
The highest-volume commercial thin-film technology globally — CdTe cells offer competitive efficiencies, excellent temperature coefficients, and outstanding performance in real-world conditions compared to STC ratings. The presence of cadmium requires specific handling and end-of-life management considerations. BIS CRS registration under IS 16077/IEC 61646 and IS/IEC 61730 is mandatory for Indian market access.
Applicable Standards — IS 16077 and IS/IEC 61730 Explained
Three Indian Standards apply in parallel to BIS CRS Registration of Thin Film Terrestrial Photovoltaic Modules. All three must be addressed in the BIS-approved laboratory test programme — this three-standard requirement is a key distinction from consumer electronics BIS registration, which typically references a single IS.
The primary performance standard for thin-film terrestrial PV modules — specifying the test requirements to confirm electrical, thermal, mechanical, and environmental performance over the product's lifetime. Covers Initial Stabilisation, STC Measurement, Insulation Test, Wet Leakage Current, Temperature Cycling, Humidity-Freeze, Damp Heat, UV Pre-Conditioning, Mechanical Load, Hail Impact, Light Soaking, and Outdoor Exposure tests.
Specifies the construction requirements for the safety of PV modules — covering materials, design, and component specifications that must be met before the module can undergo safety testing. Part 1 defines the constructional safety class (Application Class A, B, or C), insulation requirements, accessible surface treatment, and junction box and connector safety specifications.
Specifies the test programme for PV module safety — complementing Part 1 by defining the specific tests that verify the construction requirements are met. Covers Electrical Insulation (dielectric withstand, wet insulation resistance), Mechanical Integrity (cut susceptibility, bypass diode thermal test), Fire Rating, and Water Ingress tests under defined environmental conditions.
How Thin Film Module BIS Registration Differs from Crystalline Silicon
Manufacturers and importers who already hold BIS CRS registrations for crystalline silicon modules should be aware of several important differences when registering thin-film modules — the BIS registration categories are separate, the applicable standards differ, and the test programme for thin-film modules has unique requirements not present in the crystalline silicon programme.
The performance standard IEC 61646 is specific to thin-film technologies — it includes an Initial Stabilisation step and Light Soaking test that are absent from the crystalline silicon standard IEC 61215, reflecting the unique stabilisation behaviour of amorphous silicon and CIGS films after initial exposure to light. A crystalline silicon BIS registration does not cover thin-film modules.
Crystalline silicon (mono-Si and poly-Si) modules are registered under IS 14286:2011/IEC 61215, which has a different performance test programme optimised for crystalline silicon. The IS/IEC 61730 safety tests are shared between both categories. Manufacturers with a crystalline silicon BIS registration must obtain a separate registration for thin-film modules.
Unlike crystalline silicon panels — which have stable electrical characteristics from manufacture — a-Si thin-film modules exhibit a significant power output change during the first hours of light exposure (the Staebler-Wronski Effect). IS 16077/IEC 61646 requires Initial Stabilisation and Light Soaking test sequences to characterise this behaviour before all performance parameters are reported. This requirement is absent from crystalline silicon BIS registration.
CdTe modules contain cadmium — a heavy metal requiring specific handling and end-of-life documentation. While BIS CRS registration under IS 16077 and IS/IEC 61730 does not contain cadmium-specific requirements beyond safety, manufacturers should be prepared for questions about cadmium content during BIS technical scrutiny and should document end-of-life management plans in their product documentation.
4 Pillars of BIS Registration for Thin Film PV Modules
A BIS CRS Registration Certificate is granted to a specific combination of manufacturer, manufacturing site, product category, and brand. If any of these four parameters changes — new factory, new brand, new module technology — a fresh BIS application is required.
BIS licence granted only to the actual manufacturer. Importers and traders cannot hold it independently.
Each factory site requires its own licence number — the same module type from two different production lines or plants needs two separate registrations.
Thin Film PV Modules (a-Si, CIGS, CdTe) — separate from crystalline silicon modules. Each thin-film technology may require separate registration depending on BIS grouping policy.
A separate BIS Registration Number is required for every brand or trademark — even for an identical module from the same factory.
Key Performance and Safety Tests Under the Applicable Standards
All tests for BIS CRS registration of Thin Film PV Modules must be conducted at a BIS-approved laboratory. The test programme is more extensive than for consumer electronics — encompassing performance tests under IS 16077/IEC 61646 and safety tests under IS/IEC 61730 (Parts 1 and 2).
Thin-film modules — especially a-Si — must undergo Initial Stabilisation (light soaking) to establish a stable electrical state before STC power output, conversion efficiency, I-V curve parameters, and fill factor are measured. This is the foundational test of the IEC 61646 programme and the primary determinant of the module's declared rated capacity in watt-peak (Wp).
Measures leakage current between the active semiconductor circuit and the module frame/accessible surfaces under wet conditions — simulating rain, dew, and condensation that modules experience across decades of outdoor operation. Critical for safety in rooftop and ground-mount installations where personnel may contact wet module surfaces.
Subjects modules to repeated thermal cycling between defined low and high temperatures — simulating the thermal expansion and contraction stresses that thin-film module encapsulants, substrates, and solder bonds experience during daily and seasonal temperature variations in Indian climatic conditions.
Exposes modules to high humidity at elevated temperature (85°C, 85% RH) for 1,000 hours — assessing resistance to delamination, encapsulant degradation, corrosion of metallic contacts and bus bars, and thin-film semiconductor layer degradation under the long-term humid conditions common across India's coastal and monsoon-affected regions.
Cycles modules between high humidity and sub-zero temperatures — simulating the combination of moisture ingress and freeze-thaw stresses that can cause micro-cracking, delamination, and junction box ingress in modules deployed at altitude or in seasonally cold regions of India.
Applies defined pressure loads (uniform or point) to the module surface — simulating snow load, wind load, and personnel load during installation and maintenance. Verifies that the module frame, glass, and internal circuit interconnects withstand mechanical stress without delamination, cracking, or electrical failure.
Projects ice spheres at the module surface at defined velocities and impact angles — assessing resistance to hail damage in areas of India susceptible to hailstorms. Modules must show no visible damage or measurable degradation in electrical performance after hail impact at the specified test conditions.
Safety tests under IS/IEC 61730 (Part 2) verifying that the module's insulation between the active circuit and its mounting frame/accessible surfaces withstands defined high-voltage application (dielectric withstand test) and maintains adequate insulation resistance under wet conditions — the primary electrical safety tests for installation and user protection over the module's operational lifetime.
Domestic vs Foreign Manufacturer: Process Compared
The core BIS CRS registration requirements — standard compliance, laboratory testing, and BIS portal submission — are the same for both domestic and foreign manufacturers. The key procedural difference is the Authorised Indian Representative (AIR) requirement applicable only to overseas manufacturers.
- Apply directly via the BIS CRS portal (crsbis.in)
- No AIR requirement — manufacturer applies directly
- Factory address is the Indian manufacturing facility
- Ensure the product is on the BIS CRS mandatory list under MNRE notification
- Product samples tested at a BIS-recognised laboratory in India
- Apply the BIS R-Number mark only after registration certificate is received
- BIS may conduct a factory inspection at the Indian facility during review
- Must appoint an AIR in India before the BIS application can begin
- AIR manages all portal submissions, laboratory coordination, and BIS correspondence
- Factory address is the overseas manufacturing facility
- Manufacturing licence / business registration from the overseas authority required
- Product samples tested at a BIS-approved laboratory in India
- BIS factory inspection may be required at the overseas facility or waived
- Registration issued in the manufacturer's name with AIR on record
Document Checklist for BIS CRS Registration — Thin Film PV Modules
The document set for BIS CRS registration of Thin Film Terrestrial Photovoltaic Modules covers technical product documentation, facility and quality records, and brand ownership evidence. Complete and fully consistent documentation is the most effective way to minimise BIS scrutiny rounds and avoid delays.
- Trademark / Brand Registration Certificate — Copy of the registered trademark for the brand name under which the thin-film PV module is marketed in India — required for each brand under which the module is to be registered.
- Factory Address Proof — Official documentation confirming the legal registration and operating status of the thin-film PV manufacturing facility — factory licence, business registration certificate, or equivalent documentation establishing the manufacturing site address.
- Product Test Report (BIS-approved laboratory) — The complete test report from a BIS-recognised laboratory confirming compliance with IS 16077:2013/IEC 61646:2008 (performance) and IS/IEC 61730 (Part 1):2004 and (Part 2):2004 (safety) — addressing all required tests across the three applicable standards. This is the most critically reviewed document in the BIS application for thin-film PV modules.
- PCB Layout & Critical Component List (CCL) — For the module's junction box electronics, bypass diode circuit, and connector assemblies — the CCL must list all critical electronic components with manufacturer names, model numbers, and ratings, fully consistent with the BIS test report.
- Product User Manual / Installation Guide — Complete installation, commissioning, maintenance, and safety manual for the thin-film PV module — covering rated electrical specifications (Voc, Isc, Vmpp, Impp, Wp, efficiency), mounting requirements, grounding instructions, safety warnings, and end-of-life guidance.
- Product Technical Datasheet — Full electrical and mechanical specifications of the module — rated peak power (Wp), open-circuit voltage (Voc), short-circuit current (Isc), power conversion efficiency, temperature coefficients, module dimensions, weight, glass specifications, frame material, junction box IP rating, and connector type.
- ISO 9001 Certificate — Current quality management system certificate for the manufacturing facility, demonstrating the quality framework underpinning consistent thin-film module production.
- AIR Appointment Letter (foreign manufacturers) — Formal appointment of an Authorised Indian Representative, with the AIR entity's registration documents and authorised signatory photo ID — mandatory for overseas manufacturers without an India liaison office.
7-Step BIS CRS Registration Process — Thin Film PV Modules
BIS CRS registration for Thin Film Terrestrial Photovoltaic Modules follows a seven-step process. The typical end-to-end timeline is 8–14 weeks — with the extensive three-standard laboratory test programme (IEC 61646 + IS/IEC 61730) taking 4–6 weeks and BIS portal submission and scrutiny taking a further 4–8 weeks. The test programme for thin-film modules is considerably longer than for consumer electronics, due to the duration of damp heat, humidity-freeze, and temperature cycling tests.
Confirm the specific thin-film technology (a-Si, CIGS, or CdTe) and verify the applicable standards are IS 16077:2013/IEC 61646:2008 and IS/IEC 61730 (Parts 1 and 2):2004. Confirm that the product falls within the MNRE/BIS CRS mandatory list category for thin-film terrestrial PV modules. Identify whether any module variants can be grouped as series models under a single registration.
Foreign manufacturers must formally appoint an AIR before the BIS application process begins. The AIR manages all portal submissions, laboratory coordination, BIS correspondence, and ongoing compliance matters in India on the manufacturer's behalf. The AIR appointment must be in the prescribed BIS format.
Register on the BIS CRS portal (crsbis.in) and complete the application form with accurate product, brand, and manufacturer details under the correct MNRE solar module category. Generate the formal test request number before submitting module samples to the BIS-approved laboratory — the laboratory requires this number before accepting samples.
Submit representative thin-film PV module samples to a BIS-recognised laboratory with specific capability for IS 16077/IEC 61646 performance testing and IS/IEC 61730 safety testing. Confirm the laboratory's BIS recognition for thin-film PV module testing specifically before committing samples — not all BIS-approved labs are equipped for the full thin-film module test programme including long-duration environmental tests.
Receive the complete test reports under IS 16077:2013/IEC 61646:2008, IS/IEC 61730 (Part 1):2004, and IS/IEC 61730 (Part 2):2004 from the BIS-approved laboratory. Compile all required supporting documents. Verify full consistency between the application form, CCL, product datasheet, and the test reports before submission — document inconsistencies are the most common source of BIS scrutiny delays for solar PV module registrations.
Submit the complete BIS CRS registration application on the portal with all supporting documents — including test reports for all three applicable standards — and pay the applicable government fees. Confirm portal status reflects receipt of the complete application before proceeding.
BIS technical officers review the submitted application, test reports, and supporting documentation. They may raise clarification queries on the CCL, module datasheet, or test report details — particularly regarding the Initial Stabilisation results (for a-Si modules) or safety class designation under IS/IEC 61730 Part 1. Respond promptly and accurately. Upon successful review, BIS issues the CRS certificate authorising manufacture, import, and sale of the thin-film PV module in India.

- MNRE and SECI tenders require BIS-registered modules — verify before bidding
Consequences of Non-Compliance
Manufacturing, importing, or selling Thin Film Terrestrial PV Modules without valid BIS CRS registration is an offence under the BIS Act, 2016 and the applicable MNRE notification. Enforcement covers all supply chain stages.
Thin-film PV module consignments arriving without valid BIS registration numbers are detained at Indian ports. With solar procurement at the scale of gigawatts, project delivery schedule delays from customs detention can trigger liquidated damages clauses in EPC contracts — making compliance non-negotiable for supply chain reliability.
MNRE, SECI, NTPC, state DISCOMs, and state nodal agencies require BIS-registered PV modules as a mandatory qualification condition in solar project tenders. Non-registered thin-film modules are disqualified at technical evaluation — regardless of price, efficiency claims, or brand reputation — cutting off access to India's largest solar demand pool.
The BIS Act, 2016 carries monetary penalties for selling CRS-notified products without valid registration. Penalties escalate for repeat and wilful violations. BIS can seize non-compliant modules at any point in the supply chain — at the port, at warehouses, or at project sites — representing direct financial losses with no immediate remedy.
Project lenders and equipment insurers for Indian solar projects increasingly require BIS certification as a condition of project finance and insurance underwriting for PV module supply. Non-compliant modules may be ineligible for project financing or may trigger policy exclusions — effectively locking the module supplier out of the utility-scale solar segment.

BEE Registration & EPR Authorization for Solar PV Panels, Cells & Modules India 2026 — Complete Guide
In addition to BIS CRS Registration, thin-film PV modules may also require BEE Registration under Schedule 35 (energy performance) and EPR Authorization under CEEW14 (e-waste management). See our companion guide to BEE and EPR compliance for solar photovoltaic products for the complete process and document requirements for both certifications.
Frequently Asked Questions
Do all three thin-film technologies (a-Si, CIGS, CdTe) use the same BIS standards?
Yes. All three thin-film technologies — amorphous silicon (a-Si), CIGS, and CdTe — are covered under the same three-standard combination: IS 16077:2013/IEC 61646:2008 for performance, and IS/IEC 61730 (Part 1 and Part 2):2004 for safety. However, the specific test requirements within IEC 61646 differ somewhat by technology — most notably, a-Si modules require an additional Initial Stabilisation and Light Soaking sequence that reflects the unique Staebler-Wronski stabilisation behaviour of amorphous silicon. The laboratory must confirm the technology-specific test requirements before the test programme begins.
Can IEC 61646 and IEC 61730 test reports from overseas laboratories be used for BIS CRS registration?
Existing IEC 61646 and IEC 61730 test reports from internationally accredited laboratories are a valuable technical foundation and can significantly reduce the time and cost of the Indian test programme by informing the BIS-approved lab's test scope. However, a test report from a BIS-recognised laboratory remains a mandatory requirement for the BIS CRS registration application — existing overseas lab reports cannot directly substitute for BIS-lab testing. Rego Services advises on how to leverage your existing international test data most effectively and identifies the specific additional testing required at the BIS lab.
If I manufacture both CIGS and CdTe modules at the same facility, do I need separate BIS registrations for each?
Yes. CIGS and CdTe are distinct thin-film photovoltaic technologies with different semiconductor compositions, manufacturing processes, and performance characteristics — they are treated as separate product types for BIS CRS registration purposes. A manufacturer producing both CIGS and CdTe modules at the same facility would typically need separate BIS registrations for each technology type. Rego Services confirms the specific registration structure required for multi-technology thin-film manufacturers before applications are filed.
What does the MNRE small manufacturer exemption mean for thin-film PV module BIS registration?
MNRE has periodically issued notifications extending BIS CRS exemptions for solar module manufacturers below specified production capacity thresholds — effectively allowing small producers to sell without BIS registration during the exemption period. These exemptions are time-limited and have been extended multiple times. Manufacturers who believe they may qualify should verify the current exemption notification status directly, as exemptions that have lapsed are not a valid defence for non-compliance. Rego Services monitors MNRE exemption notifications and advises clients on their current applicability.
✓ Key Takeaways
- BIS CRS Registration is mandatory for Thin Film Terrestrial Photovoltaic Modules (a-Si, CIGS, CdTe) in India — required before manufacture, import, sale, or distribution under the BIS Act, 2016 and MNRE notification
- Three Indian Standards apply in parallel — IS 16077:2013/IEC 61646:2008 (performance), IS/IEC 61730 (Part 1):2004 (construction safety), and IS/IEC 61730 (Part 2):2004 (safety testing) — all three must be addressed in the BIS-approved laboratory test programme
