IEC 61215 is about the design qualification of a photovoltaic module. Its test sequence exposes sample modules to conditions intended to reveal design weaknesses. A report for one tested design does not mean every installed module will deliver a fixed output for 25 years. The module’s warranty is a separate commercial commitment, and IEC 61730 addresses module safety qualification separately.
What the standard is
IEC 61215 is a series titled Terrestrial photovoltaic (PV) modules: Design qualification and type approval. The second edition of the series was published in 2021. Its parts divide the work as follows:
| Part | Role |
|---|---|
| IEC 61215-1:2021 | Test requirements: applies to all terrestrial flat-plate module materials, including crystalline silicon and thin film |
| IEC 61215-1-1:2021 | Special requirements for crystalline-silicon modules |
| IEC 61215-1-2, -1-3, -1-4 | Particular requirements for cadmium telluride, amorphous silicon and CIGS thin-film modules |
| IEC 61215-2:2021 | Test procedures |
Compared with the previous edition, the 2021 text adds tests such as a cyclic mechanical load and a potential-induced degradation (PID) detection test for crystalline-silicon modules, and test methods for flexible modules.

What the tests look at
Sample modules go through parallel test sequences, and the same module is not subjected to every test. The stresses include:
- Visual inspection, maximum power and insulation measurements before and after each sequence.
- UV preconditioning to stress the encapsulant and back-sheet.
- Thermal cycling between low and high temperature extremes, with current applied during part of the cycle.
- Humidity-freeze and damp heat exposure, to test moisture ingress and corrosion.
- Static mechanical load applied to the front and rear surfaces.
- Hail impact with an ice ball.
- Hot-spot endurance, to see how a module copes with a shaded or mismatched cell.
- Bypass diode and wet leakage current checks.
Representative conditions in the edition-2 test procedures are 200 thermal cycles from -40 to +85 degrees Celsius, 1,000 hours of damp heat at 85 degrees Celsius and 85 percent relative humidity, a standard static load of 2,400 Pa on the front and rear surfaces (with an optional higher front load for heavy snow regions), and a 25 mm ice ball at 23 m/s for hail. The standard sets the exact levels, sample counts and sequences, so use the standard itself, not a summary, for a procurement specification.
| Stress | Representative condition |
|---|---|
| Thermal cycling | 200 cycles from -40 to +85 degrees Celsius |
| Damp heat | 1,000 hours at 85 degrees Celsius and 85 percent relative humidity |
| Static mechanical load | 2,400 Pa on the front and rear surfaces (optional higher front load for heavy snow regions) |
| Hail impact | 25 mm ice ball at 23 m/s |
Pass criteria
A module must not show major visual defects, must keep its insulation and wet leakage current within limits, and must not lose more than a stated fraction of its maximum power after each test sequence. A 5 percent limit is commonly cited for maximum power degradation, and it is assessed per sequence, not once over the whole programme. Check the text of IEC 61215-1 for the criteria in force.
What IEC 61215 does not do
- It does not set a minimum efficiency or power rating.
- It is not a safety standard. That is IEC 61730.
- It does not predict service life or substitute for the product warranty.
- It does not by itself show registration in India or a place on the ALMM list.
What should a buyer check?
| Document | Question it answers |
|---|---|
| IEC 61215 design qualification report | Was this PV module design tested under the stated standard and edition? |
| IEC 61730 safety qualification report | What safety tests cover the module design? |
| Product warranty | What does the seller or manufacturer promise and under what conditions? |
| Indian registration and scheme evidence | Does the exact model meet the current applicable BIS and procurement requirements? |
Test duration, cost and pass criteria depend on the applicable edition and product design; ask for the actual report rather than relying on a generic figure.
IEC 61215 and Indian procurement
For an Indian project, distinguish testing to an IEC standard from a local registration or procurement requirement. IS 14286 is the Indian standard that corresponds to the IEC 61215 series. BIS revised it in 2023 into parts that mirror IEC 61215:2021, with the crystalline-silicon requirements in Part 1, Section 1, and BIS registration for crystalline-silicon modules refers to it together with IS 61730. Check the applicable BIS scheme for the exact module and the project’s current documentation requirements.
The MNRE ALMM page publishes List I for PV modules and List II for PV cells. ALMM is not itself an inverter list, and a standard test report alone does not establish that a module appears on the current ALMM list.
How certification normally proceeds
- The manufacturer chooses an accredited test laboratory and submits sample modules of the design.
- The laboratory runs the sequences and issues a test report.
- A certification body reviews it and issues a certificate for the named model or family.
- For India, BIS registration is a separate step based on BIS-recognised laboratory reports.
- A change in materials, cell supplier or construction may need re-evaluation.
Common problems with certification evidence
- A certificate for a different model, wattage class or bill of materials than the one supplied.
- A report that refers to an older edition than the one the contract requires.
- A claim of “IEC 61215 certified” with no document.
- A design change after testing, for example a different back-sheet or encapsulant, without re-evaluation.

Best practices
- Ask for the certificate and the test report for the exact model.
- Check the edition, laboratory and date.
- Request IEC 61730 evidence alongside IEC 61215.
- Confirm the Indian registration and the ALMM entry separately.
- Keep the documents with the project file and recheck them if the model is substituted.
Common mistakes
- Treating a standard’s name as a certificate.
- Using a certificate for one model to support another.
- Reading the test as a 25-year guarantee.
- Skipping IEC 61730 and the Indian registration check.
- Quoting a cost or duration figure from a generic source.
Key takeaways
IEC 61215 qualifies a module design through accelerated stress tests. It is not a safety standard, an efficiency rating, a lifetime promise or an ALMM entry. Ask for the report for the exact model, check the edition, and confirm the Indian route separately.
Sources checked 14 October 2026: the MNRE residential CFA guidelines list IEC 61215/IS 14286 and IEC 61730 among PV-module technical specifications, and the MNRE ALMM page identifies the module and cell lists. An engineer should check the current standard edition and local registration route for a procurement decision.
