Recent price increases are discouraging, but friends have asked us to continue doing the Bulk Buy. We will keep shopping for good deals as long as you think this service is needed. All equipment is new, first quality and carries the manufacturer's warranty. Module warranties range from 20 to 25 years on power output. A 25 year warranty module does not last longer than a 20 year warranty module.
Long warranties are a marketing gimmick.
A 30 year design life for PV systems is realistic. Modules will likely last longer. The best way to determine a module's potential life is by how long the manufacturer has produced that specific cell technology and by that model's measured field performance. Trace inverters carry a standard 2 year warranty and offer an optional 5 year extended warranty. Warranties do not include shipping costs or loaners.
