Who issues and owes the warranty?
Match the legal seller, warranty issuer or holder, legal manufacturer and any service entity. Do not infer one party's obligation from another party's name or certificate.
Model and order evidence guide | Reviewed 24 August 2026
Solar Module Warranty and Claim Evidence Review
Match the issuer, exact product, written version, buyer duties and claim evidence to the actual order before relying on a warranty statement.
Short answer
A warranty is only as reliable as the exact issuer, product, order and written version it covers. Public product pages, test standards or generic brand statements do not define duration, activation, exclusions, evidence duties, remedies or cost responsibility for a specific order. The dated quote, PI and referenced warranty document control the accepted commercial scope.
Six Questions That Control Warranty Coverage
Review these questions against the offered model and order documents before comparing headline warranty wording.
02
Which product and order are covered?
Freeze the exact model, construction, serial range, quantity, order date, PI, invoice, destination and installation context.
03
Which written version applies?
Record the document title, revision, issue date, model annex, activation rule, transfer or registration requirement and accepted order reference.
04
What is covered and measured?
Review the stated product or performance coverage, measurement method, conditions, tolerances and evidence duties without importing a public curve into the order.
05
What exclusions and buyer duties apply?
Review installation, operation, maintenance, transport, storage, notification, inspection and recordkeeping duties written for the applicable product.
06
What remedy, cost and process are written?
Review eligibility, decision authority, possible remedies, labour, removal, freight, duties, site access and other cost allocation without assuming an outcome.
What Technical Evidence Does and Does Not Show
Standards, commissioning records and failure guidance can support an evidence review. None creates or extends a commercial warranty for an order.
IEC 61215-2 test procedures
IEC describes design-qualification test procedures for terrestrial PV modules. That technical scope does not define the commercial warranty accepted for a particular order.
IEC 62446-1 system records
IEC describes customer handover documentation, commissioning tests and inspection for grid-connected PV systems. Those records can support review but do not decide warranty coverage or remedy.
IEA PVPS failure information
Failure fact sheets help buyers and experts describe failures, risks and possible interventions. A failure category alone does not prove cause, coverage or claim acceptance.
Climate-specific O&M guidance
IEA PVPS explains that temperature, humidity, UV, rain and wind can contribute to failures and that O&M should reflect climate. Guidance does not replace the applicable order terms or site evidence.

Confirm in order documents
Reference the accepted model and warranty version in the dated quote, PI and related written documents.
Evidence for an Existing Order Review
A reported issue becomes reviewable when the order, product, use context and evidence can be linked. Submission does not guarantee coverage, acceptance, timing, replacement, credit, compensation or logistics responsibility.

Buyer Questions
Does one warranty period apply to every JUSTSOLAR product?
No. Duration, performance terms, exclusions and remedies can vary by model, construction, legal manufacturer, seller, order date and referenced warranty version. A public product category or brand statement does not extend one warranty document to every module, battery, inverter or system component.
What defines the warranty accepted for an order?
Match the legal seller, offered model, legal manufacturer, production site, order date, PI, model annex and referenced warranty document. Only the authorized written documents accepted for that order define duration, activation, transfer, exclusions, evidence duties, claim process and possible remedies.
What evidence is needed for an existing warranty review?
Provide the order or invoice number, model, serial numbers, affected quantity, issue and discovery date, plus relevant photos, measurements, installation records, inspection or test evidence and shipping or handling records. Review does not guarantee acceptance, timing, replacement, credit, compensation or logistics responsibility.
