Tesla Drastically Increases Price of Solar Roof (electrek.co) 180

Tesla appears to have drastically increased the price of its Solar Roof tiles in an update to its configurator and quote estimates. Electrek reports: After years of delays, the Tesla Solar Roof is finally gaining momentum with a sharp rise in installations over the last few quarters. The increased deployment came after Tesla launched version 3 of its Solar Roof tiles, which brought a significant price decrease through optimization and faster installation process. Tesla kept refining the product and changed its online cost estimates a few times, decreasing the price again last summer.

But now Tesla appears to have changed course and significantly increased the price of its solar roof in its online configurator. Several Electrek readers and prospective solar roof buyers reached out this weekend to let us know that they are seeing higher prices for the same quotes. Last summer, a quote for a 3,947-square-foot roof with a 12,3 kW solar roof tile system was $54,966 before incentives. Now the Tesla Solar Roof configurator shows prices between $79,938 and $100,621 for the same size roof. While this is a sharp increase in price, Tesla also appears to try to make its online quotes more accurate with a new "roof complexity" factor. [...] However, in this case, the least to the most complex options all result in higher prices than previously quoted for the same address with the same square footage.

      Well there's upkeep on the solar cells, inverters and batteries. Solar panels degrade over time, and at 20 years most are down to about 80% of new capacity, and fall off after that. The inverters last for maybe 10-15 years before they fail catastrophically due to capacitors failing or such. Batteries last 7-10 years.

      What this means if you're going to spend 10k on panels, 5k on inverters/switching and 5k on batteries, you have an upfront cost of $20k and need to have payback in under 10 years. I've run the numbers for this at my home and have never been able to make it work. I used 24,466.1 kWh last year and it's way cheaper to buy the power, even with the rate increases, than is it to buy and install solar. Net-metering here is ok, but you have to pay to upgrade the transformer, and any excess is paid at a .0025 USD per kWh rate, not the .014 USD per kWh rate they charge you at. Also if your system is >10kw you have to have a $1 million insurance policy.

      Simply put it's just not worth it to do solar.

        OTOH I've made profit on my installation and in fact have now paid for it 3 times over. That with older generation panels and inverters too.

        My payback time was originally calculated at 5.5 years but due to steady increases in the retail price, my time worked out at 2.8 years. Since then, I have also gradually reduced my usage through installation of LED lights etc and now routinely export to the grid at a rate that exceeds the connection costs.

        • That's a rapidly dwindling resource though. During sunny times, the spot rate that places will pay for solar is actually dropping to almost zero (negative in some cases). As more and more people using solar rise, the value quickly falls to zero.

        I put solar panels on my house 5 years ago, and I think they have paid for themselves (allowing for the tax credit). I don't claim that my example is typical, and there are many houses where panels will only pay off at about 15-20 years. One of the reasons it works is that I live in a state with:
        1. Lots of sun
        2. Expensive electricity rates (over $.55/kWh during summer afternoons).
        3. Good net metering policies.

          While my situation is not as favorable as yours, my 6-year-old solar installation has also paid for itself:

          2. Low cost electricity rates (due to hydro in the Pacific NW -- $0.11 per kWh).

            8 years isn't particularly difficult to get from batteries if you are very careful with them. For a home battery you would probably keep them in the range 20-80% SoC for longevity.

            Remember that these are lithium polymer batteries, not lead acid.

            • Very careful == not using much power and losing most of the utility of a battery.

              I seriously doubt you can get 8 years out of LiPo, either. 500 charge cycles in 8 years is only 62 charge cycles a year. Maybe this works for some people, but it does not fit my idea of off-grid power sourced from solar and batteries.

              For a fixed site install, I would much rather deal with a big nickel-iron setup or rebuildable lead acid. You have the space to scale up both and the weight is irrelevant.

                The commercial ones are not 500 cycles, they use a different chemistry. Also a cycle is 100% to 0%, so if you are only doing 20-80% that's only 60% of a cycle right away. Also lithium cells degrade faster when heavily discharged or kept at a high state of charge, which is why they avoid the top and bottom 20%, so actually a 20-80% cycle is much less than 60% of a full cycle.

      • Solar panels degrade over time, and at 20 years most are down to about 80% of new capacity, and fall off after that.

        This is a complete fabrication. The 20 years at 80% number you provided isn't an average, it's the required federal warranty. Most of the manufacturers beat the number significantly. There is NO known life for solar panels. The earliest and roughest produced panels first produced in the 70's are still working in most cases.

      Aesthetics is important to many people and they are willing to pay for what they perceive, correctly or incorrectly, as improved aesthetics. If someone has a lot of disposable income, I could easily see them paying the extra $70K for a modest improvement in aesthetics. $70K nothing to them and doing so won't affect their day-to-day life in any way at all - they are not going to skip one of their vacations this year or pull the kids out of private school to pay for it.

      Where exactly is "here"? I paid a bit over $20k (before rebates/tax/etc) for 8.3kW about 2 years ago. I received multiple quotes from multiple companies.

      $5.5k for 13.2kW is ~41 cents per kW. That seems an order of magnitude too low.

      Well, for one thing, a Tesla solar roof includes not only solar panels, but also... a roof. I don't think your $5.5k quote includes that part.

        You're paying for the pretty, and paying a lot for it. A new roof with standard solar panels for me would be in the $25k-$30k range. I'd love a Tesla Solar Roof, but until I win the lottery, that's not going to happen.

          And the bragging rights. What you're not paying for is cost effectiveness. Solar tiles will hit the sweet spot then years from now when the price comes down, efficiency goes up, and structural integrity is proven. Until then it's mainly a stunt.

        My house is about 80 years old and still has the original roof tiles. I looked at getting them replaced and prices came in around $30k AUD. Regular SolarPV is about $3-6k depending on size of the system (6-10kW), so round up to approx $40k AUD ($30k USD).
        The Tesla option is still $50k over that, more than double the price.

    • The key is that you get a roof. And not just a normal roof -- one which is really, REALLY robust -- bullet-proof, practically -- though whether that really translates into a much longer lifespan for the roof remains to be seen.

        I had a quote last year for a new roof. $30k USD including solar panels. The Tesla option is now over twice that price.
        Also worth noting, roof materials are already engineered to be fit for purpose, so 'bullet-proof' is a gimmick. My current roof is over 80 years old. I doubt Tesla tiles will be useful for that long.

    • A solar ROOF is an actual full blown high end roof, not just solar panels. It's like getting a slate roof that generates electricity.
    • What does a tesla solar roof give for the extra $70k? For that matter, what did it give for the extra $40k when it was cheaper? It looks slightly different?
      It gives you a complete shingled good looking roof, that as a side effect produces electricity.

      No idea where you live, but my father has to replace the roof of a house he inherited. So the price difference between simple new shingles versus a Tesla solar roof is not much bigger than a new roof + conventional solar plant.

      A 4000 square foot roof with conventional shingles would cost upwards of $40K for a complete re-roofing. And a 12.3KW system installed on that new roof would run $37-40K.

      That's 80k for a composite roof. You switch that to concrete or ceramic tile and you'd add another $20-30k. The Tesla roof being constructed of glass is more like the ceramic tile in that it has similar durability and 100+ year life.

      Although the price increase sucks, it's still a reasonable price, I would expect the price to continue to fluctuate until there are several hundred thousand installed and they've worked out all the kinks. . And since when is a 4000sqft roof reasonable? That's a fricken McMansion roof.

    All construction materials have their prices up since the pandemic... it is just getting worse.. I am guessing it may be related.

  • From what I read even people who had already pushed contracts and had some prep work done, were having prices raised.

    The reason is, maybe few have noticed but all kinds of basic material costs have skyrocketed. This is all a sign of higher material cost for production.

    If you don't think it's worthwhile still, well just try and estimate replacing a traditional roof now... that too is increasing.

  • Just to clarify this is about roofing tiles that generate power from the sun like solar panels, and not big flat solar panels.
    Big flat solar panels are at an all time low, but due to dwindling production & supply this may be going up too.

  • It only depends on how long it takes to make its cost back. If it takes too long, the product does not exists, too fast, a reason to raise the price.
