    •  yep, haven't seen specs, efficiency? cost? DIY? (0+ / 0-)

      doesn't look like home installers/self install either
      yet they advertise they sell them thru roofing companies...so that's interesting as well.

      I am guessing these are low efficiency cells, I can't remember why I think that, from a previous convo about them here...but the idea is grand...

      The shingle is stamped metal with a channel for the wires.., nails like a regular shingle, I like these alot.

      Now when the chinese knock offs show up in Home Depot I'll be all over it :>

      I would also notice they only license a couple of roofing companies in norcal, hopefully they have someone experienced enough in solar design to do a good job, rather than sell cause they are Neato.

      which they are...

      so:
      * efficiency?
      * cost?
      * why no self install?

      as to making your own solar panels, this idea looks pretty tempting, the cells are available, sheet metal can be ordered stamped and cut..maybe initially pricey, but watercut/lasercut steel is crazy cheap...like 125$ for 6 1/8 x 6 x 18 wall plates I had made.  A stack of 50 17 ga pieces would be a lunch break...holes, perimeter, no burrs.  Get a Harbor bending brake and Bob's yer uncle.

       inverters available, all the tech is available for DIY...so...why can't we buy the panels again for DIY install?

      They are missing it here...'Home Depot is calling, line 3'

      HD sells instant hot water heaters and all kinds of similar mundane but could be dangerous tech, this product is pretty safe compared to all the other heavy duty electrical items sold there...

      thanks for the link.

      this time :>

        •  there's ways around that for DIY (0+ / 0-)

          and most DIY's know a guy, who knows a guy, but basically I think you are right, in that the  work has to be done to some degree by a licensed contractor and inspected and signed off.
              I asked the Redwood Alliance about that and I am pretty sure they said DIY was ok for rebates and tax credits...except for the electrical hookup part....but worth asking again, it was a while ago.

          And thanks for reminding us of that.

          However, I will look into that because essentially, homeowners are allowed to do their own work. I am able to wire to the subpanel, but past the subpanel   no.....
            For a DIY solar install the hookup to the grid however is another matter and should be done and /or supervised by a licensed electrician. ...which of course can be the homeowner as well.
              And that hookup part may be the part that 'requires...etc'

            The other people that will get all up in your grid are insurance inspectors and bank inspectors, there for any number of reasons...and that's worth factoring in as well for the DIY..those people can be even worse to deal with sometimes.

              And as an aside, for all that officiousness I have seen some very shifty professionals and licensed contractors along with the honest and hard working trustworthy ones.

            In my house I recently bought, it had a new service panel put in by a licensed electrician, and inspected by the city building inspector...who didn't apparently go inside to see the connections to the old wiring.

          It had all been shoved very very tightly, like no movement possible, thru the one conduit to a hanging junction box, where the feeds from the new subpanel were then spliced to the old wiring.

          * 18" box hanging on the old wiring. not kidding.
          * no color coding...noooo labeling
          * runs to two more smaller junction boxes a few feet away
          * too many romex pieces in the feeder conduit

          all done by a licensed contractor.

          and that was before the vandals got in and chopped out the 220v romex to the utility room with an axe...while it was on.
            Yep. true story.

          and then the 'licensed contractor' the bank hired to fix a few things and had been in the house many times,  ...had failed to notice that the power was still on with these cut ends hanging there for anybody to blunder into.

          So, there are contractors and then there are contractors....whether licensed or not...ymmv.

        •  cool, 12% efficiency...good for thin film (0+ / 0-)

          and sometimes overall better because it can be installed in more places than panels...great pictures of their installations.

          On big box/warehouse roofs, their framing is light and this has been an excuse, that the roof needed expensive alterations to support the framing etc, so CAN"T BE DONE

          well, with this, not only CAN it be done on many roofs without frame reinforcements, it can cover a bigger area and than the heavier and more efficient 20+% solar panels...and thus be 100% better than no solar installations at all.

          Seriously, local communities must require this on all new construction for commercial and multiresidential housing.
