Tesla reportedly has some in-house teams, even while bringing on more third-party installers. TeslaĪfter you and Tesla agree on a design, it will pull permits and put you on the schedule to install. Obstructions like this can raise the cost of a Solar Roof. All of these are higher than the average cost of residential solar in the US in 2021, as reported by consulting firm Wood Mackenzie: $2.99 per watt for an 8-kilowatt system. Another estimate from Texas ranged from $6.05-$6.77 per watt.
A Solar Roof without batteries in Illinois had an estimated cost of $5.72-$6.54 per watt depending on roof complexity. Other estimates returned much lower costs. Without batteries, the system costs a whopping $12.87 per watt. The final price includes receiving $48,800 back from the federal government in tax credits. (This house does have a large, 8,313-square-foot roof.) Optional Powerwalls are $10,500 each. That Solar Roof estimate breaks down to $176,600 for the solar part of the roof and $29,600 for tearing off the old roof. Steep pitches, multiple levels and a lot of obstructions could drive up the cost. Tesla estimates 12 kilowatts of regular solar panels and a Powerwall at the same location will cost $26,966.Īnother factor that could alter the price of your system is the complexity of your roof. Tesla's online estimate for a house in Dallas offered 12.46 kilowatts of solar generation and a Powerwall battery for $168,400. Musk himself did not clarify the statement.If your goal is to generate solar for the least amount of money possible, a Solar Roof isn't for you. "We're not there yet."Ĭorrection: When Elon Musk referred to "hundreds" of solar roofs being installed, Tesla later clarified that his number included roofs that were ordered or partly installed. "It's highly likely that great engineers and incredible technologists - and a lot of those people might be at Tesla - are going to be able to take this very difficult challenge and engineer the heck out of it and get us to that cost parity," Beebe said. Tesla says solar roof installations will scale up later this year and into 2019. "It's not just a roofing shingle anymore, it's a power plant on your roof."Įxperts anticipate a wave of new solar installations within three to five years. "I would expect these solar roofing tiles, in just a few years, to be quite reasonably priced if they can get the market interest that they're hoping for," said Dan Kammen, an energy professor at University of California, Berkeley. Tesla promises 30 years of solar-power generation. Ultimately, Tesla's goal is to make the tiles a cost-effective option, partially by ensuring they're more durable than other rooftops. "Traditionally in the summer my power bill is around $400, $450 in the summer.

"I don't think this will ever pay for itself honestly," he said.įor people who don't need a new roof but want to install solar energy, traditional panels are definitely cheaper.īut Huynh is excited to be an early adopter and see his energy bill decrease. Huynh's roof cost him about $100,000, though he did need to replace his roof anyway. Tesla's customers are paying a premium for the tile's sleek look. "They said it was kind of proximity to their headquarters, so that they could do quick troubleshooting," Huynh said. Huynh asked them why his home was chosen. While traditional solar panels can be installed in a day, it took a team of 10 to 15 workers two weeks to install this roof. I thought there'd be extreme delays, I just didn't know how long it was going to take," said Huynh. "I was actually extremely surprised I got the call, just because you never know what this stuff, right. He preordered them as soon as possible, and the roof was installed earlier this year. One of the customers with the tiles already installed is San Jose resident and Tesla Model 3 owner Tri Huynh. And that's been a big challenge I think for Tesla, but certainly for the whole industry overall - to try and miniaturize it in a way that keeps it cost-effective and also gives it the very reliable performance that solar is known for," said Andrew Beebe, managing director of Obvious Ventures. "Making things small actually changes a lot of the way the technology will work. But it turns out this tech is difficult to shrink and manufacture. Solar tiles, like large solar panels, use silicon solar cells to convert sunlight into electricity. Personal Loans for 670 Credit Score or Lower
