THE SHORT ANSWER
Under federal warranty guidance, “full” and “limited” have specific meanings for written consumer-product warranties. A longer term does not by itself make a warranty full or comprehensive. [1]
Read the designation and scope
Locate the actual written warranty for each product. Identify whether it is titled full, limited or multiple, and which components receive which coverage. The FTC explains that a multiple warranty can provide full coverage for one period and limited coverage later. [1]
Compare the remedy
Record whether the warrantor repairs, replaces, refunds or supplies a prorated credit. Note who chooses the remedy and when it becomes available. A replacement part may be valuable while still leaving removal, access, shipping and installation costs outside the written promise.
List owner duties and exclusions
Find notice deadlines, maintenance instructions, proof requirements, transfer conditions and exclusions for damage or misuse. Do not summarize these as “25-year warranty.” Ask the seller to identify every separate workmanship or roof promise and the entity obligated to perform it.
Check future-owner treatment
The FTC’s examples show that transferability can be a specific term rather than an automatic feature. [1] Read the actual solar warranty and account-transfer process. Save purchase evidence and serial numbers so a buyer can attempt a claim under the correct owner name.
Avoid affiliation assumptions
A contractor’s ability to sell equipment does not establish manufacturer authorization for every repair or claim. Ask what role the installer performs, what the manufacturer decides and whether another qualified provider may service the system under the written terms. Obtain answers from the warrantor when uncertain.
