Default Tesla's Solar Roof Is Finally Ready For You to Buy

Not sure whether to post this here or in techno-babble. Story here.

Quote:
Tesla is opening up its online store for its solar roof tiles Wednesday, Elon Musk said in a message on Twitter. More details—presumably including pricing—will be disclosed shortly.
-- I'm also not sure how much difference it'll make. How many people who wouldn't buy separate roofing and solar panels will buy them rolled into one? And will the roofing and the solar production have the same lifespans, or will they both wind up becoming a waste product because one of them has failed? But it would seem that it would be cheaper to install the combination; and there may be people who really don't like the look of panels.

There is something strange about that pricing, although it could be the batteries. We didn't spend anything close to that cost for panels, even with the cost of a roof added, for a larger house. We have net metering with the power company, so we don't store power on site. Assuming the same cost as our panels and a roof, this looks like the batteries would be on the order of $40k to have enough power storage. I wonder if they have a plan for areas that have net metering and would not want to pay that kind of cost for the batteries - I know I could not have brought my wife around to that kind of money for them.
Of course, if they will replace any failing tiles for the life of your house, this could be a better deal than any roof.

There are definitely people who don't like the look of the panels. Different circumstances mean they can be more visible on some houses than others. But if they're going to be highly visible, a lot of people don't like the look of something huge and plasticky that appears to have been tacked on to a completely different style of roof as an afterthought. And even if the homeowner doesn't mind, it doesn't mean it won't affect the resale value of their home or be rejected by an HOA.

I don't think many people are going to rush out and redo their roofs immediately, but having a product like this available means that people can start to design new homes with these in mind. They can design the exterior of their home to integrate these seamlessly into it, so they look like they belong. On a contemporary home they could potentially look nicer than boring composite.

Personally, my house is on the South side of the street, with a sharply pitched roof, so the part of the roof that gets good sun exposure is on the opposite side that you can't see from the street. So I don't really care what solar panels look like. I'd shop for panels based purely on function and value. But under different circumstances looks could be a consideration.

As of right now, electricity is just so cheap and I use natural gas appliances where I can, so it would take forever for any of this stuff to pay for itself. And I use electricity more at night so I'd need good battery capacity, which isn't cheap. I like the idea of going solar, but the technology needs to mature a bit before it's a home run looking solely at the economics. I'm pretty sure it will reach a point that I can justify doing the work within the coming decades.

Ah. They've updated the article, and it now includes pricing.

-- wow. I'd have to look up and multiply out a bit what it cost me when I had the roof done recently, as while the house is close to that size the roof wasn't all done at once; but I'll just say that the cost of 30-year roofing alone, at least in this part of NYState, is nowhere remotely near in the ballpark.

I haven't priced solar systems, though, let alone ones with batteries -- people getting solar setups in this area almost always feed the power into the regular power grid.

But, yeah, a "warranty for the lifetime of your home"? That's potentially a couple hundred years, maybe even longer; though not everything's built for that sort of lifetime. (Will Tesla even still be in business?) I suspect it's the more common "as long as the same people who bought the system are living in the house", which brings it down considerably, especially on average as many people move frequently.

I would say it is, as Errata said, aimed primarily at new home construction. Developers can include it, or add it as an option for high end and "luxury" homes. It also looks very nice. As mentioned, there are lots of people who can't or won't put conventional solar panels up due to the appearance.

If I was buying a new home, and that could be rolled up into the mortgage, I would absolutely go with those for the roof.
As for affecting the resale value, it seems that the solar panels increase the resale value by about 80% of the cost of the panels (at least, that's what it did for us and from what I can tell that is typical). I don't know what batteries would do to the resale value.

Default Solar Roof

I have researched solar for a couple years, but the front of my house faces South, so panels would be visible. I had my roof replaced a few years ago and there was a company selling solar shingles then and they weren't too much more expensive. The extra costs comes from the power inverter, which cost more then my roof cost and it would only save me about $50 a month so the pay-off would be over 10-15 years. My new roof should be good for another 20+ years, so I guess I'll wait until then to see how it works out then.

That is the key question. Tesla is still a very young company and though it is worth a lot of money it actually has fairly little profit.

Thorny, you'll note that those prices are for, and compared to, prices in a specific location (New York state). The comparison shows that the roof prices they're comparing to are all high-value roofs.

I reroofed my house about 15 years ago (my goodness, really?) with aluminum shingles that have a 50 year warranty. The company that did it is still in business. Like Errata, my house faces north, but at the time I reroofed, home solar wasn't the easy thing it is now. Also, trees shade a lot of my roof.

Yes, I noted that. And I mentioned in my earlier post that my home is also in New York State.

However, "New York State" isn't really a specific location so far as prices are concerned. Prices in Westchester County and in Schuyler or Putnam or Yates may be wildly different for many things; I wouldn't be surprised if they're wildly different for roofs.

-- I'm not surprised when a company stays in business for fifteen years. For one to stay in business for a couple of hundred years, while not unheard of, is unusual. However, as I said, I wouldn't be surprised if the warranty isn't for "the lifetime of the home" but instead for 'as long as the same people own the same house'; at any rate, that's what a lot of "lifetime" warranties for other house appliances come down to.
