Tesla Solar with Flat Roof

edited November -1 in Energy Products
I started a quote for Tesla solar and seem to be running into a challenge because I have a "flat" roof where I only have 1/4 inch per 12 inches slope.

Has anyone else encountered this? They're going to get back to me, but it sounds like they may not be doing installs on "flat" roofs on the east coast. I'm not sure yet.

Thanks.

    Sorry to say, I don't think there is any chance they would install the solar tiles on a flat roof. An angle is preferred to get more sun, but the three reasons that are more problematic:

    1. The tiles need airflow under the titles, and a reasonable slope makes this work.
    2. The tiles are not sealed together. A slope makes the rainwater flow down to the next tile. A flat roof means the water just flows through the tiles to the roof below.
    3. Snow and ice loads could be significant if you're an area with snow/ice conditions. The tiles are strong, as you can walk on them. I'd worry more about ice forming and causing damage when they are flat.

    Traditional solar panels might work, but they would likely make some kind of fixture to tilt the panels up. I'm not sure many solar companies would do this kind of installation. Sorry to be the bearer of bad news.

    Lots of companies install on flat roofs. Talking to a couple Tesla certified installers now. It isn’t hard to tilt the panels. Just surprised Tesla won’t do it. My guess is they’re trying to get as cookie cutter as possible to minimize costs.

    @GoneSailing - I was focused more on the solar tiles - which is unique to Tesla. Solar panels from Tesla or other should work if tilted, but perhaps Tesla doesn't offer this option currently.

    I’m not interested in solar tiles, those won’t work on a flat roof. I’m interested I. Tesla Solar panels, and spent $100 to be told no. I was curious if anyone else encountered this.

    Are they going to return the $100?

    I haven’t pushed on them yet about a refund. Talking to a Tesla certified installer today. If I can figure out when / if they’ll unlock grid charging, it might make sense to install the small array and Powerwalls. I haven’t given up yet, but want it to at least feel ok.

    Most electrical utilities in the U.S. do *not* allow Powerwalls to be charged from the grid, except during StormWatch events. Check with your utility *before* committing to a contract, if grid-charging is important to you. Get the answer in writing.

    They'll return your $100. It's just a deposit and you're not committed to anything until you're in contract.
    I have a solar roof but certainly wouldn't want it on a flat roof. I've seen a number of solar roof owners (via a group I'm part of) who have a mix of sloped and flat roof sections and they generally cover the flat roof sections in another material.
  • Hi what other materials do they use for the flat roof section? It'd be a shame if they use a low quality material that doesn't last as well as the rest of the roof
