In true Musk fashion, Tesla sold its Solar Roof to investors as a cheap way to generate off-grid power at just $22 per square foot back in 2016. But customers who were willing to take the company up on the offer found that the prices for installing the solar tiles immediately ballooned far beyond what Tesla originally quoted, a major disparity that triggered a class-action lawsuit, which the company later settled.

The product quickly turned into a major thorn in Tesla's side. While Musk promised the company would be installing 1,000 Solar Roofs a week, reality lagged far behind at only several dozen a week at its peak, according to Electrek.
