    [​IMG] The future is like a freight train. It is not going to be stopped.

    [​IMG]Al S. – CleanMPG – May 10, 2017

    Have you considered ordering a Tesla Solar Roof that uses glass tiles with embedded solar cells instead of conventional asphalt, tile, or cedar shake roof topped with a solar panel solution add-on?

    Early this morning, Musk announced the Tesla Solar Roof through the brands SolarCity subsidiary will be available next year.

    Elon Musk's tweet(s) regarding this block buster Solar Roof announcement are shown to the right. -->

    What the Tesla Solar Roof tiles will look like.​

    From the Tesla Blog, more details were released...

    Tesla’s mission is to accelerate the world’s transition to a sustainable energy future by creating products that are so compelling, there is no alternative. Solar energy has always been part of our master plan, and we recognized the need for a roof that is simultaneously affordable, durable, beautiful and integrated with battery storage.

    Solar Roof complements a home’s architecture while turning sunlight into electricity. With an integrated Powerwall, energy collected during the day is stored and made available any time, effectively turning a home into a personal utility. Solar energy can be generated, stored and used day and night, providing uninterrupted power even if the grid goes down.


    Solar Roof is more affordable than conventional roofs because in most cases, it ultimately pays for itself by reducing or eliminating a home’s electricity bill. Consumer Reports estimates that a Solar Roof for an average size U.S. home would need to cost less than $24.50 per square foot to be cost competitive with a regular roof. The cost of Solar Roof is less. The typical homeowner can expect to pay $21.85 per square foot for Solar Roof,1 and benefit from a beautiful new roof that also increases the value of their home.

    Solar Roof uses two types of tiles—solar and non-solar. Looking at the roof from street level, the tiles look the same. Customers can select how many solar tiles they need based on their home’s electricity consumption. For example, households that charge an electric vehicle every day may want more solar tiles on their roof.

    In doing our own research on the roofing industry, it became clear that roofing costs vary widely, and that buying a roof is often a worse experience than buying a car through a dealership. Initial contracts tend to be overly optimistic, and later customers face hidden costs that were never mentioned up front.

    At Tesla, we believe in transparency and putting the customer in control. That’s why we created a Solar Roof calculator that lets homeowners estimate the upfront price of Solar Roof, as well as the value of the energy it can generate for their home. The calculator is based on factors like roof size, the average local price of electricity, and how much sunlight a neighborhood receives throughout the year.

    As shown in the graph below, the cost of our non-solar tiles is comparable to regular roofing tiles.2 Although the cost of our solar tiles is more expensive up front, it can be more than offset by the value of energy the tiles produce.3 In many cases, the reduction in a home’s electricity bill over time will be greater than the cost of the roof.


    Design & Durability

    Solar Roof will be available in a variety of designs, including Smooth and Textured (available this year) and Tuscan and Slate (available early 2018). Made with tempered glass, Solar Roof tiles are more than three times stronger than standard roofing tiles, yet half the weight. They do not degrade over time like asphalt or concrete. Solar Roof is the most durable roof available and the glass itself will come with a warranty for the lifetime of your house, or infinity, whichever comes first.


    Customers may place an order for Solar Roof today on the Tesla website. Installations of Solar Roof will begin in the U.S. this summer and we expect installations outside the U.S. to begin in 2018.

    In another tweet from Tesla this afternoon, the company’s focus was again revealed to the public in 140 characters or less again.

    That is a darn nice looking roof!​

    I hope the real installed costs match the costs laid out above minus the on-site Li-Ion battery storage solution.

    About Tesla

    Tesla’s mission is to accelerate the world’s transition to sustainable energy.

    Tesla was founded in 2003 by a group of engineers in Silicon Valley who wanted to prove that electric cars could be better than gasoline-powered cars. With instant torque, incredible power, and zero emissions, Tesla’s products would be cars without compromise. Each new generation would be increasingly affordable, helping the company work towards its mission: to accelerate the world’s transition to sustainable energy.

    Tesla’s engineers first designed a powertrain for a sports car built around an AC induction motor, patented in 1888 by Nikola Tesla, the inventor who inspired the company’s name. The resulting Tesla Roadster was launched in 2008. Accelerating from 0 to 60 mph in 3.7 seconds and achieving a range of 245 miles per charge of its lithium ion battery, the Roadster set a new standard for electric mobility. Tesla would sell more than 2,400 Roadsters, now on the road in more than 30 countries.

    In 2012, Tesla launched Model S, the world’s first premium electric sedan. Built from the ground up to be 100 percent electric, Model S has redefined the very concept of a four-door car. With room for seven passengers and more than 64 cubic feet of storage, Model S provides the comfort and utility of a family sedan while achieving the acceleration of a sports car: 0 to 60 mph in about five seconds. Its flat battery pack is integrated into the chassis and sits below the occupant cabin, lending the car a low center of gravity that enables outstanding road holding and handling while driving 265 miles per charge. Model S was named Motor Trend’s 2013 Car of the Year and achieved a 5-star safety rating from the U.S. National Highway Traffic Safety Administration.

    In late 2014, Tesla CEO Elon Musk unveiled two dual motor all-wheel drive configurations of Model S that further improve the vehicle’s handling and performance. The 85D features a high efficiency motor at the front and rear, giving the car unparalleled control of traction in all conditions. The P85D pairs a high efficiency front motor with a performance rear motor for supercar acceleration, achieving a 0 to 60 mph time of 3.2 seconds – the fastest four-door production car ever made.

    Tesla owners enjoy the benefit of charging at home so they never have to visit a gas station or spend a cent on gasoline. For long distance journeys, Tesla’s Supercharger network provides convenient access to high speed charging, replenishing half a charge in as little as 20 minutes. Superchargers now connect popular routes in North America, Europe, and Asia Pacific.

    Tesla’s vehicles are produced at its factory in Fremont, California, previously home to New United Motor Manufacturing Inc., a joint venture between Toyota and General Motors. The Tesla Factory has returned thousands of jobs to the area and is capable of producing 2,000 cars a week.

    The company is expanding its manufacturing footprint into other areas, including in Tilburg, the Netherlands, where it has an assembly facility, and Lathrop, California, where it has a specialized production plant. To reduce the costs of lithium ion battery packs, Tesla and key strategic partners including Panasonic have begun construction of a gigafactory in Nevada that will facilitate the production of a mass-market affordable vehicle, Model 3. By 2018, the gigafactory will produce more lithium ion cells than all of the world’s combined output in 2013. The gigafactory will also produce battery packs intended for use in stationary storage, helping to improve robustness of the electrical grid, reduce energy costs for businesses and residences, and provide a backup supply of power.

    Tesla is not just an automaker, but also a technology and design company with a focus on energy innovation.

    I have a moderate interest in this, but it has been difficult to get specific numbers, such as how many watts per square foot this can generate.

    These are great - but you sacrifice efficiency for aesthetics. I prefer getting as much power as possible from the area I have available on my roof.

    I'm looking forward to some examples of actual cost once it starts shipping. I'm wondering where the cost of the inverters fits in.

    I can see how cost and durability as compared to conventional roofing materials can increase installation rates if truly competitive.

    I wonder if Tesla (and others) will get into home siding as well?... In northern areas, south facing walls could get quite a bit of solar energy as compared to shallow angled roofs or roofs pointed the wrong way.

    there are at least 4 established players in this space already plus a half dozen noobs.

    It's a very good solution for certain situations like historic buildings, but otherwise not compelling.

    it's going to be a niche, BP bailed because of its inherent inefficiencies.

    ...but if they meet cost and durability parity with standard materials, why not? (when re-roofing or building new)

    The good thing about Tesla shingles it seems, is they are much tougher than the materials they are mimicking.

    I have not looked closely at the available information, but I wonder how the glass outer layer holds up to hail. My area doesn't get much hail, thankfully, and my solar panels have held up so far. <knock on wood>

    Given the much smaller sizes of the glass shingles, I hope there is a simple and cost effective way to replace individual failures or damaged tiles.

    In some areas, the traditional PV panel on a house has negative consequences on home value.
    Knowing what it takes to replace slate tiles, replacement should be simple. With few people that know how to do this being available to do the work, with zero in some areas of the country, these tiles likely being like slate in being more slippery than asphalt, being cost effective might not happen until the roofs are more common.

    Good point about being similar to slate roofs. Plenty in New England, though it is still very true that the necessary skills are quickly disappearing. There must be an added complication beyond that of slate shingles, to accommodate the conductors.

    That will likely be plug and play to keep installation labor costs down, with a 'power strip' line under each tile row.
