ISI Mark for Solar Thermal Systems, Devices and Components

Solar Thermal Systems, Devices, and Components's BIS certification license guarantees adherence to Indian requirements for quality and safety.  Important criteria comprise IS 12933 for all-glass evacuated tube solar water heating systems, IS 26544 for flat plate solar collectors, and IS 16542 for storage water tanks.  The certification process calls for application submission, product testing at BIS-accredited labs, and manufacturing inspection.  Effective April 8, 2025 compliance with the Quality Control Order (QCO) is required.  The ISI mark certifies certified goods for dependability and regulatory acceptance.  Non-compliance could result in fines, hence timely certification is quite important.
