    Man, that is a hugely misleading headline when casually glanced over. Not 95% efficiency; 95% of other panels…

    Typical panels are about 20-24% efficient. So these roof tiles are like 19-22.5%. Not bad.

      Edit: didn’t knew OP added the “compared to regular panels part”. Disregard the rest of this comment.

      I think is a good title, it’s tells how compare against regular solar panels. Saying their absolute efficiency wouldn’t really tell a lot because not everyone knows what means having a 20% efficiency.

        It’s poorly worded but anyone that thinks panels are anything close to 95% wasn’t paying attention. Even hydro power which just gravity and a turbine barely achieves 95%

        No.

        The title implies that, somehow, colored solar panels hit 95% efficiency, compared to panels that are not colored. To be clear, it should say:

        “Colored solar panels that mimic tiles roof achieve 95% of the efficiency of regular solar tiles”

        It’s poorly worded to mislead into “actual efficiency”. People looking at solar panels need the real number, not how it compares to traditional ones. This is at worst misleadingly worded, or at best, poor journalism.

      compared to regular solar tiles

      That’s why I editorialized and added that bit

    The ability to have energy generation from roof tiles is so damn cool!!! The solarpunk future is becoming more true every day, and I’m all for it!

      It’s a waste of money. Most of the tiles will be in shade. PV panels are better and easily replaced if damaged by weather.

        And roof installations for panels are expensive to put in and take out, and need to be taken out to replace roof shingles/tiles under them.

        This tech might end up being the best of both worlds for roof panels because they have the potential to remove the frame from the equation.

    20% is what standard photovoltaics were doing a decade ago. I cannot wait until these are standard on all roofs in a few decades.

    Edit: Yes I know the title is misleading, I’m saying these colored roof tiles are performing on par with the setup many Americans installed 10 years ago at the height if the subsidies.

      It’s 95% of regular panels, so it’s 5% worse.

      I would go with regular panels in that case, unless they are shaped like tiles and can provide better coverage of the roof. 5% efficiency drop but 15% coverage increase could be worth it. But I expect install costs would be quite a bit higher

        The article talks about colored graphics that can be applied to a panel. So not panels that are shaped like tiles. So they are still normal panels but with colors on them. So these are probably usefully for facades, like the side of a tall building.

    Wouldn’t you want them all to be black to maximize effectiveness? Damn marketing. In the not too distant future daily talk shows will have segments on which colours are fashionable this year for solar panels.

      Sometimes historic buildings have a strict code to follow, this might help to modernize them while keeping the historic aesthetic.

    When can I buy them?? I’ve been reading about roof tile panels for ages, but I’ve never seen on win real life.
