    Just curious to see if the Aptera team has any thoughts on how they will combat frost/ice/snow buildup on the solar panels in the winter?

    My thought?

    I doubt they will do anything as they are dark panels, all sloped and you will be moving too

    The vehicle is only 57” H if you have a need to brush off the panels after the windows

    In NJ where we had ice and snow on 44 solar stationary panels on our house for a decade…. We the sun came up, it warmed slightly my dark solar they are self cleaning! I never had to clean them off and they were in a typical PV solar panel frame Aptera’s are smooth and curved

    What about hail?

      I think they are combating that by making each individual panel easily replaceable.

      @Dennis Swaney Remember that Aptera’s panels won’t be topped with glass so they may be slightly “hail-resistant”. As @pcase said, all of the panels are (hood/bonnet, roof, hatch, tail) are removeable so should be easy to replace if damaged.

        Ah, that is good to know. Will a few spare panels be included with the vehicle? If not, I’ll immediately order some to have on hand.

        Oh, that brings up another question on damaged panels: will they be locally recyclable or can be sent back to Aptera for recycling?

        Easy to replace will not likely mean it will be a two minute job. Remember these solar CELLS are individually installed under an encapsulation (think liquid glass like substance that hardens) that needs to be carefully breached to get to the broken cell, then removing that glued down cell, gluing down a replacement cell and wiring it back up, then re-encapsulating it and making it smooth. I would dare guess “easy to replace” can be translated into a whole day’s work to fix one cell. But it’ll be worth it. Once you’ve done one, you could make it known that you can fix others, for a price.

          If I’m interpreting you correctly, you believe INDIVIDUAL cells will be replaceable. I, personally, doubt it. It is more likely entire “sections” would be replaced such as the hood or roof panels. Also, it’s more likely the panels will be “laminates” rather than a collection of “cast in place” cells. By laminate I mean a multi-layer sandwich of 2 different materials on top of solar cell circuit and something similar on the back.

          By the way, regardless of the ultimate encapsulation scheme, I’d like to make it known that I “can fix others, for a price.” 🙂

            Thank you Alain, for saying exactly what I was thinking.

              Well if you guys can fix it for me, how about adding some more solar cells for me when I get the Aptera? I see lots of places more cells will fit (across the tail, some on the sides of the hatch, and especially on the doors. If you really wanted to solar charge you could point the Aptera into the sun, open the hatch and the doors, with cells on them, and have the best angle exposure, other than jacking up the rear tire to get an even better angle to the sun.

              No problem. What’s your budget? The solar array pictured below only costs about US$250,000.00 including 34% Triple Junction GaAs-based cells. Also pictured is a close up of one of the modules.
