Panasonic integrates solar panel with residential roof

TOKYO —

Panasonic Corp has developed a new solar panel product that can be integrated with a residential roof.

It is one of the products in the “HIT” series of heterojunction solar cells, which combine monocrystalline silicon and amorphous silicon.

The new product uses a mounting system integrated with a roof. 

The solar panel can be set up on a roof without making holes in the roof, thus enabling more effective use of the rooftop. It maximizes the amount of power generation with a limited space, the company said.

Also, because its cross-section has a corrugated shape, the panel is resistant to the load of snow and can be used in regions where the height of snow cover reaches 2 meters.

    So essentially what Tesla released a few months back?

    Tesla's solar panels are manufactured by Panasonic. Tesla just provides the nice covering.

    excellent news! ANY progress in the field of solar technology is good news. Now if only we could get the gov to financially support solar instead of nuclear...

    According to a Scientific American article (https://www.scientificamerican.com/article/im-getting-my-roof-redone-and-heard-about-solar-shingles/), solar roof 'shingles' have been out since 2005.

    The concept is a bit of a no-brainer. Just need to wait until they become mainstream, and to wait for a way to deal with the triangular corners in my roof. Unless Panasonic can make the shapes to order, of course.

    People who have solar panels installed are now using the energy then feeding it back into the grid by installing batteries. These batteries are beneficial in two folds, it offsets peak energy needs and can be used as emergency back-ups in case of a black out.

    Even on the photo I can see a lot of shadow caused by the corrugation. Is it April 1st already?

    I've always said, every new home built, by law, must solar panels.

    @SenseNotSoCommon more surface area? and even in the shadow there will be some photons

    Thanks. Arguably the edges optimize the amount of solar gain as the sun rises and sets. Do these incremental gains outweigh the extra cost (and does the consumer realize just how they're paying through the nose for solar compared with other countries)?

    @Aly Rustom: They already do, have you seen the countryside lately in Japan? solar panels everywhere the government buys the power.... but for how long?

    There was another press release/story about a company called Kaname doing this last week. It's not a large part of Japan, but conventional solar panels don't get a warranty if you use them in heavy snow areas (gosetsu chitai) regardless of how steep your roof is. 2m would qualify, so I guess these and Kaname's will be warrantied. In central Honshu, the area in question will be the Nozawa-Yuzawa-Myoko triangle and Hakuba/Otari. Most of Nagano and the Niigata coast doesn't get huge amounts of snow.

    Part of the reason you'd want the warranty is that it protects you from electrical faults and freak weather, like hail or mega gusts of winds blowing heavy tree branches around, that can occur regardless of how much snow falls in your area.

    I think the tesla one's look much better.

    I have gogo. I drive.

    What I mean is, the gov doing more in terms of general solar support. For example, funding solar research, giving tax breaks for solar installation, things like that.

    Ah, it's like a surface of human's small intestine which effectively absorbs nuturition. Is it a biomimetic technology?
