All TOPCon modules in the HSM-ND48 series (covering the 210R G12R-48P range) are warranted free from defects in materials and workmanship that materially impair structural integrity or normal functioning under normal installation, use, and service conditions: 25 years from the warranty start date, the earlier of array interconnection or six months after delivery. Electroluminescence indications such as microcracks are not themselves defects unless they materially impair structural integrity or functioning.

TOPCon HSM-ND48 modules are warranted to produce at least 99% of rated minimum peak power in the first year, degrading no more than 0.40% per year, with a guaranteed minimum of 87.4% of rated minimum peak power at end of year 30, a 30-year performance term from the warranty start date. Measured peak power is assessed at Standard Test Conditions (1,000 W/m², AM1.5, 25°C) per IEC 61215 and IEC 60904, with a 3% tolerance.

For any valid claim the manufacturer will: at its sole discretion: repair, replace, or refund the defective modules, paying reasonable, customary transport for return of covered modules and delivery of repaired or replacement modules to the original delivery location. Replacements may be refurbished or remanufactured but will be electrically and mechanically compatible, with a substantially equal or greater power rating.

Product warranty refunds equal the spot price of comparable modules at the time of claim multiplied by (1 − n/25), where n is years in service since the warranty start date; performance warranty refunds use (1 − n/30). Spot price is the prevailing market price of modules of similar type, specification, and performance when the claim is assessed.

Warranty benefits are in addition to, and do not limit, rights under the Australian Consumer Law: replacement or refund for a major failure, compensation for reasonably foreseeable loss or damage, and repair or replacement where goods fail acceptable quality. Nothing in the warranty excludes, restricts, or modifies rights under the Competition and Consumer Act 2010 (Cth) or state and territory fair trading legislation.
