THE SHORT ANSWER
A prorated credit and a replacement part are different remedies. Read the warranty formula, then price the complete field scope without assuming the claim makes the repair free.
Read the formula, not the headline
Find the model-specific written warranty, covered period and credit calculation. FTC guidance describes prorated remedies that decrease over time. [1] Ask the warrantor to state the current approved amount and expiration without estimating future claim value.
Identify uncovered project work
List diagnosis, removal, shipping, substitute equipment, roof access, electrical labor, permits, utility updates and recommissioning. A credit against a component may not pay these costs. Require each exclusion or allowance to be visible in the service estimate.
Check replacement compatibility
A discontinued original model may require a different module, inverter or supporting device. Ask for the technical compatibility basis and whether more than one component changes. Do not compare credit amount with retail panel price alone.
Control the claim timeline
Save case number, authorization, proof requirements, shipping instructions and claim deadline. DOE maintenance guidance supports traceable corrective-work records. [2] Do not remove or dispose of the failed component before the warrantor and service provider confirm custody requirements.
Close the accounting and equipment file
Record credit applied, owner-paid work, installed serial, remaining coverage and monitoring result. Keep the warranty decision separate from the contractor invoice. This makes the real remedy understandable during later service or home sale.
