Elon Musk, co-founder and CEO of Tesla Motors, has a well-earned reputation for creating innovative 21st-century products that combine attractive designs with exceptional performance – and generate high levels of consumer interest as a result. The latest Musk technology to make a splash is the Tesla solar roof, which he revealed to great fanfare in October 2016.
According to the company, Tesla will begin accepting on a waiting list for the solar roof in April. Tesla’s roof is now expected to reach homes before the end of 2017, leading many homeowners to wonder – is the Tesla solar roof worth waiting for, or should you install solar panels now?
Standard solar panel technologies are typically evaluated based on their performance, durability, and warranties. However, there are relatively few technical details available for Tesla’s solar roof shingles. Tesla has not revealed how efficiently the panels will generate power, what kind of warranty the company will offer, or how they will be installed.
The company has also claimed that their tiles are significantly stronger than a traditional roof tile, and even shared video footage during the launch to demonstrate their durability. That being said, Tesla hasn’t provided any information about durability or stress tests – standard information that is publicly available from most solar panel manufacturers.
One thing is for certain: Tesla solar roof shingles look great. The shingles, which are made of glass, come in four different patterns that have the look of a standard roof, with one key difference – they generate electricity for your home. The solar cell embedded in Tesla roof tiles isn’t visible from the street, unlike a traditional solar panel.
Tesla solar roof pricing is unclear, but experts expect it will be expensive.
Tesla hasn’t released any official pricing information for their solar roof tiles. However, their own website states that the solar roof tiles will have a “lower cost than a traditional roof when combined with projected utility bill savings.”
Multiple journalists have attempted to come up with price estimates based on Tesla’s guidance, and they’ve all come to the same conclusion: the Tesla solar roof, like most of Tesla’s other products, will be a high-end purchase that comes with a premium price tag.
Consumer Reports crunched the numbers and determined that a Tesla solar roof would cost somewhere between $70,000 and $100,000, based on Tesla’s own pricing guidance. This is much more expensive than a standard asphalt roof replacement, which should cost homeowners between $8,000 and $16,000 depending on their roof size and property location. Labor and installation costs could add an additional premium to the price of the Tesla solar roof, although the lack of information about its technical design makes this price premium difficult to estimate. But think of it this way: roofers aren’t trained as electricians and vice versa, so it’s likely that more highly-specialized contractors will be needed to install the Tesla roof shingles, increasing costs further.
Timeline: when will the Tesla solar roof come to market?
Tesla solar roof technology isn’t available on the market yet. According to the latest reports from Tesla, the solar roof will be rolled out sometime in 2017. However, it’s unclear exactly when the product will be ready for consumers.
Tesla has indicated that they will manufacture the tiles in partnership with Panasonic at the company’s factory in New York, which won’t be open until mid 2017. However, the auto manufacturer is notorious for production delays across its line of luxury electric vehicles, most famously on the Tesla Model X crossover SUV. Whether Tesla solar shingles will face the same production delays as Tesla cars remains to be seen. Our own estimate is that homeowners shouldn’t expect the Tesla solar roof to be available nationwide until mid-2018.
Price is a serious consideration if you’re deciding whether to wait for the Tesla solar roof. However, an equally important factor to keep in mind is whether your home is a good candidate for solar roof tiles.
Most existing solar shingle technologies are also known as building-integrated photovoltaics (BIPV) because they are integrated with your existing roof, and are a similar size and shape to standard roof tiles. Tesla has created something different.
In August 2016, Musk first explained the difference between solar shingles and Tesla’s solar roof: “It’s not a thing on the roof. It is the roof.” Unlike other solar shingles, Tesla’s roof tiles are designed to completely replace your existing roof. As a result, the most cost-effective way to install them is when your home is being built, which means that they are best suited for homebuyers who have a say in the design and materials of their newly constructed home.
While this doesn’t mean that they can’t be used on existing homes, retrofitting your roof with Tesla solar tiles will come at an additional expense, because you’ll need to pay contractors to remove your old roof first. As a result, retrofitting your roof with Tesla solar tiles is only practical when your roof is already due to be replaced.
Just as Tesla Motors doesn’t make electric vehicles for the masses, Tesla Energy isn’t developing a solar roof that belongs on every home. In many ways, the company’s solar roof product is similar to its first electric car. If you are an early adopter of new technologies, don’t care about price, and are prepared to wait for a product with an uncertain manufacturing timeline, then waiting for Tesla solar roof tiles could be the right decision for your home.
However, there are always risks associated with installing a brand-new, untested technology. Unlike Tesla’s solar roof tiles, many of the premium solar panels currently available on the market today are produced by well-known consumer electronics manufacturers (such as Hyundai, Panasonic, Kyocera and LG) that have been producing solar panels for a decade or more.
Additionally, waiting to go solar has its risks, even if you’re interested in a brand-new technology. The cost of going solar is falling every year, and there are premium solar panels already available today that come with high efficiency ratings and a sleek black design. If you wait years for the Tesla solar roof, you will lose out on years of savings on your electricity bill. You also run the risk of missing out on financial incentives for solar – many state tax credits have already expired, and the federal investment tax credit for solar will be phased out starting in 2020.

If you’re ready to explore the solar options for your home, join the EnergySage Solar Marketplace and get custom quotes from solar installers in your area. You might be surprised by just how much you can save now by installing traditional solar panels on your roof today.
