What to Look For
Warranty Transferability
Some warranties transfer to new owners if you sell your home. This can increase property value. Check if warranty is transferable before purchasing.
Manufacturer Reputation
Choose panels from established manufacturers with good track records. A 25-year warranty is only valuable if the company is still in business to honor it.
