    I’m pretty sure solar roof was introduced as a way to pump stock when Tesla was doing poor financially

    Did any other manufacturers build their own version? It seems like the right long term idea but the lack of other players seems to indicate there's some underlying issue that isn't solved yet.

      There are a few companies, I remember Invisible Solar which produces modules which look like traditional clay tiles.

      The market pitch is different tho, they are aimed at providing less effective solar for places where you have a hard need to keep the old look, old churches, monumental buildings and such.

      GAF did. There are two issues: 1) too expensive 2) not modular. I like that I can separate my solar decision from my roof decision. Panels make that possible.

      I did consider but there are 2 issues. 1. Efficiency. Not all roof parts can be exposed to sun. You overpay 2. You need to time it with roof change

    When they rolled out the product with tiny tiles I always thought musk was being to ambitious. The smaller the tiles the harder a solar roof gets.

    Surely there’s a middle ground where a roof is made of something big and panel-sized, rather than a conventional roof with panels as another layer on top?
    • IneffablePigeon 43 minutes ago
      The middle ground is integrated solar panels, where you have normal sized panels but they are flush with the rest of the roof and there are no tiles underneath them. There are normal tiles surrounding the panels. This is the style I tend to see now for new builds, but it’s more expensive than just layering on the panels if your roof is already in good shape.

        Flush with the rest of the roof seems like a mistake. What if you need/want to replace them with a different sized panel?

          That and op said it's more expensive. Why would you do it flush, then? Looks? Eh, I prefer practicality over form and many architects would agree with being more honest.

    Tesla's inability to produce solar panels is why I'm most skeptical of the whole terafab datacentre in space stuff.

    Everyone gets caught up in the thermal management stuff and the power density stuff and whatever but to me that's a red herring.

    The real issue is that Tesla has never known the ability to produce solar panels at scale and Musk said in that recent interview with Dwarkesh that he intends to do all the solar production in house.

    So where's he getting the sand from? How are they going to purify it at scale? How are they going to turn it into ingots and then wafers and then cells and panels when they haven't even been able to produce a slim fraction of panels without all those extra steps over the past decade for their roofs?

    And if the goal is to have the industrial capacity to do all this in a few years and produce solar panels on the scale that he's talking about -- why doesn't he just lay those bad boys down en masse on Earth and solve the impending climate crisis and our current energy shortages?

    It just doesn't make sense.

      You are mixing up Tesla and SpaceX. SpaceX already produces solar panels for the 10,000+ satellites it has in space.

    Sad. A great idea ruined by poor business practices.

    This current crop of tech bros and companies really is the worst for humanity. Failed tech and projects I can understand, but it’s the total, consistent and persistent lack of care and disregard for people, customers & the planet. They never clean up their own mess either, and I even disliked the kids who did that at playgroup 40 years ago!! The sole ambition is always money & power. I read that article aghast at multiple points.

    I recently had 9.2kw of solar panels installed in the SE of England, the actual cost of the panels themselves was ~£1k. I’ve seen new installs going up with standard cheap panels nicely inset, flush into the roof itself. The roofers themselves have told me they are cheaper than a traditional roof due to the decreasing price of panels and ever increasing price of tile. Got a listed property with a slate roof? Solar could save you potentially £10k+ according to one roofer I spoke to.

    Panels were and always were going to be dumb commodity items. There’s literal fields literally filled with the things everywhere. Compare to say something like the PowerWall which they still sell bucket loads of and I have one myself, Elon be damned…

    However, the PowerWall still suffers from that worst of all tech bro sins of trying to limit YOUR access to YOUR data. I wanted to add an ESP CYD to display all my Home Assistant data when we had solar installed to help us as a family see what was happening in realtime. It’s incredibly useful - In typical HN fashion I rolled my own and avoided ESPHome, making it just how I wanted and I love it! 3d printed case and all! Boots in 2 seconds and just works!

    I had obviously and wrongly assumed the PW3 would be easy as pie. Getting realtime data out of the PW3 is a freaking Kafka-esque nightmare… the only workable solution to which was setting up another dedicated ESP32 to connect directly to the PW own perm on wifi and weird custom API and shunt the data over BT. Tesla could break it all at a moments notice with an update and i’ll be out of hours trying to fix it. The whole thing is cat&mouse hoop jumping, the likes of which I haven’t seen since the earlier console hacking days. Tesla will display the realtime data through their servers, through their app, but if you want that…

    Anyway, please everybody who’s all gung ho on the Anthropic and OpenAI hype trains remember - every single big tech company has had the exact same disregard for you, your family, your home and your planet since the start. It’s probably more consistent than Moore’s law at this point. Nothing is going to be different this time around.

    As someone who owns a Solar Roof, this news is disappointing. Many of my friends have said it's the best roof they've ever seen, and I even sometimes get compliments from people who drive past.

    "The economics never worked either. An average Tesla Solar Roof costs approximately $106,000 before incentives, compared to roughly $60,000 for a traditional roof replacement plus conventional solar panels — a $46,000 premium. The payback period stretches to 15-25 years, compared to 7-12 years for traditional panels. In 2023, Tesla settled a class-action lawsuit for $6 million after customers accused the company of bait-and-switch pricing, with one plaintiff seeing their contracted price jump from $72,000 to $146,000."

    Ouch. The whole point was that it was supposed to be cheaper.

    Yep. Fred Lambert, the usual suspect.
