Warranty deadline calculator
Pick the brand, put in the install date, and see what is actually outstanding on that piece of equipment.
Most solar brands have no registration deadline at all. Of the 19 in this catalogue, 3 have a dated window. The rest attach conditions instead: things that must stay true for the full term to hold, with no clock and no warning when one stops being true. This tool shows whichever applies to your brand.
Some brands measure from delivery or shipment instead. The brand page says which.
A commissioning app registers this one, and your job is verifying it happened.

No deadline
There is no clock on this brand. There are conditions instead, and an unmet one shortens the term without telling anyone.
What has to stay true
If the customer wants 20 or 25 years, the paid extension must be bought within 24 months of shipment. The standard 12 years needs nothing

The window and the conditions come from each manufacturer's own published document, read on the date shown on that brand's page. Terms change. Check the document that applies to the model you installed before you rely on this.
Why most brands show no deadline
When this catalogue was first checked in July 2026, thirteen of thirteen Australian residential solar brands turned out to have no short registration deadline. That was not the expected answer. The US market added a few real ones, notably Silfab's 180 days, but the pattern held: the dated window is the exception.
What the documents describe instead is conditions. GoodWe gives 10 years only while the inverter is connected to the SEMS portal, otherwise five. Tesla gives 10 years on a Powerwall only while it stays online, otherwise four. REC's ProTrust cover exists only if a certified installer registered the install. None of those has a clock, and none of them tells you when it has been broken.
A countdown cannot express any of that, which is why this tool shows a checklist when there is no date. Inventing an urgent deadline for every brand would make a better marketing page and a worse tool.
What starts the clock
The other trap is the start date. Several brands measure the term from something other than the day you installed it. Jinko starts at delivery or 180 days after manufacture, whichever is earlier. BYD starts six months after production unless you kept the delivery note. FranklinWH starts at install or 12 months after manufacture, whichever comes first. Stock that sat in a warehouse burns cover before it is ever switched on.
This calculator measures from the date you give it. Where a brand measures from delivery or shipment instead, its own page says so, and the difference is worth checking before you tell a homeowner how long they have.
This runs on every install, automatically
Claim Timer computes the deadline at the moment equipment is added, stores it, and never recomputes it. If a manufacturer changes its policy later, old equipment keeps the deadline it was actually held to.
