The Ministry of New and Renewable Energy (MNRE) has released revised guidelines for series sanction of solar PV modules for conducting testing in test labs for implementation of Solar Photovoltaics Systems, Devices.
The guidelines are delivered to enable labs/manufacturers in the formation of series of products for approval of product family comprising change in design, materials, etc. for performance testing of SPV Modules in test labs for compulsory registration with BIS for implementation of the Order.
Guidelines for Selection of Samples:
1. Design qualification and type approval of crystalline silicon (including bifacial) and Thin Film terrestrial PV modules.
A total of eight modules shall be taken at random from a production batch or batches, in accordance with the procedure given in IEC 60410. All the modules should contain the following clear and indelible marking laminated inside the glass as per IS/IEC 61730-1, clause 11.
- Name, monogram or symbol of the manufacturer,
- Model number,
- Unique serial number,
- Nominal wattage ± 2%,
- Year and country of origin,
- Brand name if applicable.
2. PV module safety qualification and requirement for testing.
A total of 7 PV modules (6 normal modules and one laminate) shall be taken for testing. All these modules should fulfill the requirement as stated above.
3. PV module safety qualification and; requirement for construction.
The client should submit all the details of BOMs & fabrication etc. in accordance with the related standard. The necessary IS/IEC compliance certificates where available and applicable for the pre-certified bill of material should also be submitted to the laboratory for review.
4. Product or process modifications requiring limited retesting to maintain the certification.
In case of a change in cell technology, modification to encapsulation system, modification to the substrate, modification to frame higher or lower power output (by 10%) in the identical package without a change in size and cell process and modules without a frame the requirement of limited testing for extending the certification to the module family.
5. Fire Test.
For conducting fire test, the requirement of the number of fire tests samples will depend on the size of the PV panel and fire safety class declared by the manufacturer and for this additional 3 nos. modules are required to be submitted to the test lab.
Different brands are required to be registered separately. However, it is feasible to do so based on a common test report, if the product and the manufacturing location are the same.
