Solar Roof Mockup From Forward Labs

Via Twitter, Tesla CEO Elon Musk confirmed that on or around October 28, Tesla / SolarCity will have a big reveal day.

In late October, the highly anticipated solar roof will be revealed. This roof, according to Musk, will be more attractive than a standard shingled roof, yet will incorporate highly efficient solar panels (see mock up by Forward Labs for just one example of how a solar roof might look).

Musk adds that the solar roof product will come with an integrated Tesla Energy Powerwall 2.0, as well as a Tesla charger.

Basically the goal is to incorporate everything into a single package. So, you harness the solar energy to not only power your house, but also to recharge your car (a Tesla, of course) and it’s an all-in-one setup so you simply place one order and the wheels get turning until it’s done.

In theory, it sounds like an excellent idea, but that depends really on the cost of the solar roof, as well as its efficiency.

We’ll have more details on or around October 28.

Is that a tiny house they are putting the roof on?

I hope it meets building code in Florida. GO TESLA GO…now we see why a Tesla/Solar city merger is a good idea despite opposition from Tesla haters.

No we don’t. It’s perfectly possible for SolarCity to develop solar shingles by themselves and make them work with the Powerwall. Musk’s companies are perfectly capable of working together, SpaceX helped with the model S for example.

You don’t buy a SpaceX car though, do you? You’re suggesting that Tesla build and sell solar roofs, with help from solarcity, then sell them competing with Solarcity? Solarcity already has the supply chain, installers, customer service, sales, everything in place. It only makes sense for them to merge.

Seems to me that the more practical solution would have been for Tesla to spin out Tesla Energy to SolarCity. But bailouts don’t work in reverse.

I assume this would not be subject to the 2 foot border fire code we have around here?

That is the works.

“Dual Purpose Roof”..KeepS out the elements & produceS electricity..Great for new construction or a Re-Roof , That’s Smart !

Someone in Canada has invented/produced a Solar Coating that absorbs sunlight & makes electricity…Just like solar Panels..Not yet on the market.

very low efficiency.

I hope the price of such a roof will be almost the same as a roof with no solar panels. I would add the solar production for a very small price if it is bundled with the powerwall and an integrated inverter and Tesla charger. I would add the charger for free.

Ya because photovoltaics are roughly the same in price as shingles… Dream on.

They have had this available for some time now. The cons are cost, low efficiency, and durability. I don’t see this as being a cost effective option yet but then again the Tesla crowd in general doesn’t usually have that high on their list of requirements.

The cost of a new roof is 90% manpower. Solar is almost as bad. I’m having a $9K system installed for almost 25K, and that’s the best offer I could get. A good roof, I was quoted at 15K. So, I’d pay 25K for an all in one.

Although the Solar City plant is coming to fruition in Buffalo, NY, to my knowledge Solar City has no retail operations in NY State, either because small solar installers here work on the cheap and its not profitable for SC, or else the statewide prohibition against Powerwalls and Net metering has made SC sales pointless in all of NYS without a change in legislation.

Personally, I’d rather have the net metering than the Powerwalls, since there is zero cost to me unlike other states where they charge you for a second meter or drastically in crease the delivery charges.

In downtown areas of cities, another big advancement is the development of ‘transparent’ solar panels that while, also have lower efficiency – can gleen electricity out of the huge glass areas of skyscrapers – which reduces the heat load in the summertime plus reduces the overall energy expense for the building.

Solar City’s ‘shingles’ also look promising depending on the installation cost. Roofers like the current ‘old fashioned’ 3 tab shingle since they can be almost thrown up on a roof.

A one stop shop. Seems appropriate for it to happen in San Francisco:


@ Bill H
“Personally, I’d rather have the net metering than the Powerwalls,”

I have the ultimate in net metering. I’m gone for 5 months in the summer. During that time my solar panels put all their output into the grid. I get credit for each kwh I put in and then I can pull them out on a one to one basis at zero charge when I return. ie 1 kwh in = 1kwh out, even steven. If you had to buy batteries to store that much juice it would cost a fortune.

Now add onto that that I am not forced onto time of day rates. I pay the same flat rate for electricity no matter when I use it.

Unfortunately these advantages are not available to new solar installations. Arizona Public Service is in the news constantly about their “Dark money” political contributions. They bot 3 of the Arizona Corporation Commissioners. They hate solar nowadays.

For every kW I overproduce between Noon and 6PM in May to Oct I get back 2 to 2.5kW in off peak times or winter months. I call that the ultimate NetMetering 🙂

You may want to look in to TOU as an option if you aren’t ever around during the summer months. Not all states are created equal though!

DJ and GeorgeS:

Solar and time of use are problematic here.

If you select TOU, then depending on whether the utility has 3 or 4 time periods, you’ll get 3 or 4 power piggy banks. Gone will be the ability to make a deposit during the day and a ‘free withdrawl’ at night.

Since non-TOU is legally ‘dumb’, nothing is time constrained.

I wonder how this roof would do with partial shading. With traditional panels strung together onto a large inverter, shade on a single panel will hamper production of all other panels on the string. That’s the reason I insisted on microinverters for my roof. I get significant shading in the morning and evening. It is nice to have at least some of my panels producing at full tilt during those times. Any other home in my neighborhood would suffer from the same issue. There are lots of tall trees around.

good question Brian. If Tesla really is designing the whole system one would think they would consider that. It would be interesting to know if they sub out any parts of the system. I believe they make their own inverters in their cars. So it seems they could design and build everything in this solar system and make more money.

I hope they will be able to make the solar part of the company viable economically.

It’s tough, Solar City has never been the cheapest out there…

The problems are, more than half of Tesla’s are sold in Cali, we have a lot of Spanish tile roofs…Many would be better off to have conventional tiles…

Next, if the solution ends up being like the picture above, what if the roofs aren’t facing the correct way?

Just seems like one of those things where Tesla will hope the package of a new roof, panels and a battery will be attractive enough to not shop around since you’d imagine all will be more expensive than the getting a new conventional roof and adding panels and a battery…

Expect to start seeing a lot more new-build houses with roofs designed to be ‘PV-friendly’.

C’mon Insidevs, this is news that indirectly effects EVs. Let’s try to keep the news about EVs please.

Stop trying to post everything that has Elon Musks name on it.

Considering the number of EV and PHEV owners who have solar installed, or who are very interested in installing solar, I see why they’d post the article. It’s a topic most of us are interested in.

If you’re not, quitchyerbitchin and go read something else.


Given that we have ample roof space (generally not exactly crowded with panels, eh?) and a roof with no panels has an efficiency of 0%, even a 10% efficient panel setup would be a large win if it covered substantially the entire roof.

I wonder how “modular” they are to avoid vent holes, chimneys and how it would meet fire code.
