      Anyone else super excited by this? It's not a ton of electricity but based on the amount I drive I bet being a majority off grid would be possible.

        Not me. My car is garaged at home and work.

        I really can't see such a system generating enough electricity to power the car, unless you only drive it once per week.

          Electrek did some math and seems to think 2~ miles a day would be a reasonable assumption. I wish I had a garage but mine will be outside 24/7. It'd not be enough to get me by but a lot of days I may only drive 5km if that.

          @Brian_North , I do find the idea super cool yet I would reserve my judgment on more data with regards to the return on investment... i.e. how effective vs the cost of the option (relatively to other things I'd like to have more).
          Plus how would a deployable roof look? I take it sweet knowing all what T≡SLA does.
          Time will tell! :)

          I saw someone suggest maybe it's something you can pull out or clip on when the car is parked that'd generate energy, might be a lot of cool aftermarket options for the 3. It's all so exciting.

            Not interested if I can see the cells in the roof. I want a clear view. Neat idea though.

            So many folks have been asking for it. I'm shocked to see it get an official consideration.

            In theory, it would be nice for city folk who park on the street and don't drive too often…

            I wouldn't want anything that deploys and sticks out. Remember when cars had those goofy medallions that sat just above the grill and kids would break them off? Seems like a solar sail of sorts would be asking for trouble in highly populated areas. I do like the idea of a battery tender. My dad uses one on his corvette so that he doesn't get locked in the car which he has done before he knew about the manual release. :grin:

              How about enough capacity to run the air conditioner, the brighter the sunlight, the more you need it. Also some constant heat in the winter, no matter how small, would save range.

                I live in Phoenix and having car outside would be pointless. Energy made would most likely be less then energy needed to cool the car with ac. Anyone living in Phoenix will know what I am talking about.

                  The solar cells would only have to run a fan to keep the inside of the car close to the outside temperature, not keep your tacos frozen.

                    You realize that in Phoenix for good part of the year we are dealing with 95F to 115F temperatures?

                    Lucky you... So did you plan on revamping your roof with the new solar files?

                    Actually, I spoke just yesterday with solar city reps. I am seriously considering replacing my roof with new tiles once they become available. Well, that depends on the cost as well.

                    There you go!! Well done!! See this is why AZ will beat Belgium... any time! And why I'm moving to the South of France when I retire end of 2017, where my house already has solar panels (albeit the 'traditional' kind I am afraid...)!! :)
                    On this note, could you do me a favor and ask the Solar City rep what their plans are for EU, if any? Thanks!!

                    It's an OPTION, and not everyone lives in Phoenix, and not everything has to work for Phoenix. Perfect is the enemy of good.

                      Nor should they, 115 degrees? Yikes, I'm not sure I'd last very long there.

                      Yeah but it's a dry heat :)

                      Summers in Toronto can be unbearably hot with 100% humidity. That's truly unpleasant.

                      So, here is my point. Any solar array embedded in the glass roof has to conform to the curvature of the roof. That pretty much rules out monocrystalline cells unless they are very small. The least costly would therefor be polycrystaline cells. They are less efficient. So, the power output will be quite small. But it would be sufficient to run a small fan to ventilate the interior, or in winter to power a small heater with a circulating fan. So, if it is -20 F outside and the interior is -10 F, what is to complain about. If it is a reasonably priced option, I would go for it, primarily for its usefulness in summer heat.
