Tesla Solar Roof V3: Pricing, Design, Rumored Features, Colors, Launch Date

The future looks bright for the Tesla Solar Roof as the company gears up to launch a third-generation design of its solar-harvesting tiles. After incorporating learnings from the handful of Tesla solar roofs already in operation, Tesla Solar Roof Version 3 is said to look more like a standard roof to the untrained eye.

Musk first demonstrated the roof at an October event , which featured the house of the future alongside a Tesla Model 3 electric car and Powerwall battery powered by the solar roof. Musk said in August that both he and chief technology officer JB Straubel had installed the roof on their home. Amanda Tobler, one of the first real consumers to install a solar roof, tells Inverse that Tesla did not specify the version number of the roof she had installed in March Installations have remained relatively rare, a May report found that just 12 roofs had been installed in total.

Clients regularly ask us whether we recommend clay or concrete roof tiles. At the end of the day we believe the decision is more a matter of personal taste. We present the major differences in this blog post to help customers decide which they prefer. Roof tiles all serve two broad purposes. Their primary one is to keep rain water away from the space below.

The History of Clay Roof Tiles

A few of roof the pieces were subjected to therrnoluminescence TL –dating. Two ages estimated from these RTL-accumulated doses and annual doses gave an excellent agreement with the predicted age, although one sample showed different behavior of RTL-glowcurves depending on kinds and energies of radiation, resulted in finally scattering age. Additionally, every ages evaluated from feldspar fractions offered relatively young ages even using far-RTL measurements, as well as BTL-ones. As a result, BTL from feldspar fractions possessed high sensitivity, giving highest one from orthoclase, whereas RTL from quartz and far-RTL from feldspar fractions indicated extremely weak sensitivity, amounting to three order faint intensity.

Finally, it was concluded that contamination of feldspar into quartz fraction will be negligibly small contribution in the case of RTL-measurement, while such feldspar-contaminated quartz fraction will cause erroneous result in the case of BTL-dosimetry. Already have an account?

A dated typology for Roman roof-tiles (tegulae) – Volume 19 – Peter Warry.

Published on July 30th, by Kyle Field. July 30th, by Kyle Field. Tesla CEO Elon Musk has confirmed on Twitter that the company is working to ramp up the production of its solar roof tiles to a rate of per week by the end of the year. Rollout of the solar roof tiles has been slower than the company expected back when they were first revealed in a event at the Universal Studios backlot in Southern California.

Spooling up production line rapidly. Musk originally showed off four versions of the solar roof tiles, but to date, only the textured solar roof tiles have been installed on the homes of customers. Building out the three remaining configurations of the product in the smooth, slate, and tuscan finishes would open up the product to new customers living in homes that are better suited to one of the other finishes.

Since that time, Tesla moved production out of the initial development space and into its Gigafactory 2 in Buffalo, New York , and started down what turned out to be a long road of product development. The ultimate goal was to reimagine both the roofing business and the solar business and nail the sweet spot between the two with a solar roof tile that installed faster than a traditional roof, was far more durable than your average roof, and churned out solar. The early images and videos of the roof tiles showed them looking more like LEGO blocks, with the solar roof tiles delivered and installed in pre-wired blocks of three.

LEGOs are quick and easy to put together and Musk and his team at Tesla aspired to do the same with an easy-to-install, long-lasting, solar-generating Tesla-branded glass roof. Later in the process, we learned that Tesla had been refining the design of its solar roof tiles, with a new version 3 of the roof tiles that could be the mass-market build.
