![]() ![]() Luma generally seeks local installers to put in an installation, but it's capable of doing an installation itself, as well.Initially, only gray smooth and textured black glass tiles will be available for purchase. Aquino added that, "because of the smaller shingle profile, our Solar Shingles will generally 'turn on' earlier in the day (at about one-half to almost one-third the power needed as compared with conventional solar panels at an average of 18 to 24 volts per panel to 'turn on')." The company says that because its patented shingle design allows for airflow underneath the shingle, its system has a 21-percent solar-to-electricity conversion efficiency, which is high even for rack-mounted panels. Luma also advertises a higher efficiency rate for its solar shingles. Custom roofs take into account the customer's future energy use, their roof's sun exposure, and the customer's overall budget. ![]() If a customer just wants a portion of their roof solarized, then it costs about $4.50 per Watt, although an "edge-to-edge" custom solar system can run up to $38 per square foot. Luma Solar has also been installing solar roofs for years, and it has roofs in more than 20 US states as well as a few in Canada and the Caribbean, according to the company's chief advisor Marty Aquino.Īquino said that the price of Luma's solar roof varies by the complexity of the system. ( EnergySage says that, according to solar installation data, the cost is approximately $4.90/Watt, compared to $3.14/Watt for an average rack-mounted system and $6.40 for an estimated Tesla installation). ![]() In an email to Ars, Chris Fisher, manager of Solar Product Development & Marketing for CertainTeed, said installation costs depend on the installer. Each shingle or tile contains "14 high-efficiency monocrystalline silicon solar cells" that "provide a power rating of 60 watts per solar shingle," CertainTeed says. One advantage that CertainTeed has on its competitors is that its Apollo II solar shingles have been available for about five years now, and it's possible to buy said shingles through an installer. Now, CertainTeed is a subsidiary of building product company Saint-Gobain, and it specializes not just in roofing but in "siding, fence, decking, railing, trim, insulation, gypsum, and ceilings," according to the company website.

We have deployed Solar Roof on additional homes in Q2 and are gaining valuable feedback from each new installation." The letter added that Tesla plans to ramp up more toward the end of 2018, so if you're on the reservation list, you might get lucky soon. In the company's Q2 shareholder letter, Tesla wrote, "We are steadily ramping Solar Roof production in Buffalo and are also continuing to iterate on the product design and production process, learning from our early factory production and field installations. Tesla has said that it's taking time to verify the safety of these solar roofs to make sure they'll work for decades rather than a dozen years. The company later contacted Ars to clarify that this number included homes that were scheduled for installation, not homes that were actively having a solar roof installed. In an August shareholder call, Musk said that solar roof installations were finally ramping up, with "several hundred" solar roofs being installed. Reports indicated that, as of May 31, only 12 solar roof systems had been installed, all in Northern California. Initially, Tesla employees were the only customers, until Tesla reportedly started installing solar roofs for reservation holders in January.
