Snack on the Sun with a Solar Sandwich

New Jersey-based Englert, a company that specializes in metal roofing and gutter systems, recently earned a citation from Architect Magazine for their incredible Solar Sandwich roof system.  On the surface, it looks like any other standing-seam metal roof with columns of thin-film photovoltaic solar.  Yet below that, to capture the warmth generated from hot metal roofing, there’s a grid of pex-filled purlins with a water and glycol solution for a solar thermal system.

The system connects with conventional heat transfer and distribution systems for residential and commercial hot water systems, radiant floor heating systems, and swimming pool heaters, according to Englert.

Dawn Solar Systems makes the solar thermal component, while the thin-film PV aspect is similar to what’s provided in the EnergyPeak system with Uni-Solar PV laminates.  In this case, it’s the SunNet BIPV system, which uses an Englert metal roof.

    Beautiful but oh so painful!  I just installed a standing seam roof without the glycol! …..Thanks for your articles, it is nice to know that a fellow Utahn is interested in the technology.

    Nice work Preston, as usual!  Too bad Uni-Solar is going bankrupt by mid 2011.  Englert knows it, yet they are still attempting to defraud their potential clients.  EnergyPeak, as you know, was a scam and Centria got rid of them.

      Solar Thermal integration is what “changes the game” here……. C-si technology actually needs it more because they are less efficient at higher temperatures. Thin film and Solar Thermal are a formidable combination. Kudos to the editor!

    Robert,

    You need to respond to my comments on Green Tech Media or just tell me flat out if you will be promoting my new video of a grid tied ARTEZANOS TIPV residential roof with 36 Unisolar 68′s and two solar thermal technologies (one for standard domestic water heating and one aesthetically integrated for pool heating. By the terms and conditions of our bet done on April 22, 2010, you lost a bet with me and said you would even promote my video. Did you lie? Please refresh your memory with your e-mail to me below:

    “Re: ECD FAN ARTEZANOS SOLARIZED HYBRID ROOF TILE SYSTEM 8-May-10 09:23 pm danielargue: Our bet occurred on April 22nd, so I think you have till the night of May 11th to take pictures and still be within the “two weeks or so” promise, because after 11th it will be three weeks (you can email the pictures a day or two later, as I will be able to verify the EXIF data).

    I am certain that you won’t be able to demonstrate that the existing PVL laminate product line can be integrated cost-effectively with a BARREL ROOF TILE using the HYBRID system! You know it, I know it, and soon everybody will know it.

    If you are right and I am wrong, I will apologize profusely and endorse the product in any way you wish (while preserving my anonymity, of course).

    Make sure that you will be able to explain how the laminate is attached and prove that it will hold in the summer, and reveal the price per Watt to the customer (and, of course, show us pictures)! ”

    Doesn’t this mean that this eliminates any possible snow build-up on the roof?  I love this idea!

      That is how I got started. We first invented a solution for ice dams in 2009 and later found out that we can use it as a solar thermal system.

      Would definitely make Michigan winters more palpable. Not to mention winter utility bills…

      Dennis,

         Wow! I thought Dawn Solar was the only one doing that….. If you guys ever need a more affordable roof tile solution that integrates solar pv and solar thermal in much the same way, Google: TIPV or e-mail arguelles67@aol.com

                 Here’s a link to our patents to see some graphics:
