EC&M had an interesting article last month about solar hardware and warranties. Some are totally useless, even if the company still exists. This is mostly for electrical contractors but shit rolls down to the customer.
A few excerpts
There?s promise and peril in that trend. On the plus side, declining prices make solar attractive to more customers ? from homeowners to electric utilities. But a booming market also attracts hordes of vendor newcomers looking for a piece of the action. More competition helps drive down prices, yet heavy competition also makes it tough for vendors ? particularly startups and other smaller ones ? to price their products high enough to fund enough R&D for market-differentiating performance and features. It also leaves less money to cover warranty claims."
"When a vendor exits the U.S. market, goes bankrupt, or struggles to honor its warranties, it can drag down the brand reputations and bottom lines of the contractors it works with. That risk isn?t unique to solar, of course, but the odds are higher than in a lot of other industries."
"?The inverters have a 20-year warranty ? one of the reasons we purchased them,? he wrote. The manufacturer sent him new ones, but he had to install them himself.
?I now have another inverter that will not talk to the system,? he wrote, adding that the manufacturer seems to have left the U.S. market. ?I have had no luck getting in touch with them, and the distributor has only offered to sell me a different brand ? and has had no better luck getting in contact with [the manufacturer].?
"Warranties are crap,? Brotherton says. ?Every single one has holes in it. Our industry I feel is one that you can?t say: ?It?s only this type of product? or ?It?s only the product that comes from this country.?"
One challenge is that contractors and their customers see only the warranty itself rather than its financial foundation. For example, one vendor?s marketing highlighted how its 25-year warranty was backed by Lloyd?s of London.
?Come to find out, they paid their premium monthly,? Vanderhoof says. ?The whole thing collapsed.?
