“On an October evening five years ago, Elon Musk used a former set for “Desperate Housewives” to show off Tesla’s latest innovation: roof shingles that can generate electricity from the sun without unsightly solar panels.
After delays, Tesla began rolling out the shingles in a big way this year, but it is already encountering a major problem. The company is hitting some customers with price increases before installation that are tens of thousands of dollars higher than earlier quotes, angering early adopters and raising big questions about how Tesla, which is better known for its electric cars, is running its once dominant rooftop solar business.
Dr. Peter Quint was eager to install Tesla’s solar shingles on his 4,000-square-foot home in Portland, Ore., until the company raised the price to $112,000, from $75,000, in a terse email. When he called Tesla for an explanation, he was put on hold for more than three hours.
“I said, ‘This isn’t real, right?’” said Dr. Quint, whose specialty is pediatric critical care. “The price started inching up. We could deal with that. Then this. At that price, in our opinion, it’s highway robbery.” . . . :
