Panasonic offers 25-year workmanship warranty on modules

When you’ve entered into a long-term partnership with solar giant Tesla Energy, it means you have to produce the highest quality product. That’s one reason why Panasonic Eco Solutions North America has introduced one of the longest workmanship warranty in the industry – 25 years on its HIT high-efficiency photovoltaic modules.

Panasonic signed an agreement in December that it would run Tesla’s Buffalo, New York, area Gigafactory 2 to produce its HIT modules, which are expected to be used to expand Tesla’s residential installation market . With so much riding on the success of the modules, Panasonic’s decision to extend its warranty is expected to be welcomed news to homeowners.

Combined with HIT’s industry leading temperature coefficient of -0.258%/C, which means the panels maintain optimal performance even in high temperature, the company believes the warranty will allow homeowners to see a secure and profitable long-term investment in the panels.

The industry standard warranty usually runs 10 years on workmanship, so Panasonic’s decision to more than double the standard warranty offered by many of its competitors could launch a warranty race with other module manufacturers. Panasonic also guarantees 91% of rated power over the 25-year warranty.

“At Panasonic, we are proud to not only offer top-of-the-line residential solar panels that will provide huge savings for our customers, but to also stand behind those products and ensure their longevity,” said Dan Silver, president of Panasonic Eco Solutions North America. “This 25-year warranty and industry-leading temperature characteristics give our installers yet another asset when advocating for Panasonic HIT panels to customers.”

Editor’s note: We have changed the headline to state that this is a module warranty. We regret the error.
