Tesla Solar Roof: Competitor Casts Doubt on Cost and Efficiency
Tesla Solar Roof shingles look like traditional shingles

Elon Musk made some bold claims about the Tesla Solar Roof.

Elon Musk unveiled the Tesla Solar Roof end of October 2016. He made some bold claims over the "invisible solar roof." The biggest claim he made is that the Tesla Solar Roof is going to be cheaper than regular roof.

Tom Werner, CEO of solar installer SunPower pulls that claim into question in an interview with Business Insider. He is skeptical that Tesla will be able to make their solar roof affordable.

10 years ago, SunPower offered a solar roof option, but it was too expensive for the amount of energy it produced. "You take the same material and you have less energy production because it’s a little shingle," Werner said. "And then also, because they're part of the roof, they get hot. So you have to pay to keep them cool."

"It’s a trade-off of looks cool versus costs more," he continued. "We found our customers said it doesn’t look cool enough to offset."

SunPower was not the only company offering solar shingles. Dow Chemical Company offered a solution for years, but ended production last year.

Elon Musk said that the Tesla Solar roof will be cheaper than regular roofing in November of last year. This is supposed to be true even without taking the energy production into account. This is different to what Musk said at the launch event, and has a far reaching impact.

Elon Musk said in the Solar Roof event that the cost of a Solar roof is the same as a traditional roof plus the cost of electricity you save with the Solar roof. There are no concrete numbers yet. Roof prices vary widely, making it hard to predict where the Solar Roof prices will be. We expect that the Tesla Solar roof will range at the high-end. Given that the solar roof has a much longer durability, home owners will be more motivated to by a Solar Roof. This is on top of owning a roof that is saving the planet.

Some skepticism about Musk's claims about the Tesla Solar roof is in order. Telsa has not shipped the solar roof yet. First installations are planned for the end of the year. Telsa is though the only company that can pull it off. With Solar City now integrated, Telsa has everything needed to offer a complete solar energy solution.

Besides the solar shingles, the Powerwall batteries are an essential component to make this green energy solution work. Tesla knows that ridiculous scale can be the solution to cost. The company delivered the proof of this concept with the Giga factory. No other company is even close to having a battery manufacturing facility like Tesla.

For now we are still psyched about the Tesla Solar Roof.
