Super Efficient SolarDuct Co-Generates Electricity and Heat Energy!

SolarDuct PV/T

Conserval Engineering just announced the release of their newest product, SolarDuct PV/T, which is a rooftop solar PV system that goes beyond generating renewable energy from on-site solar power.  With the SolarDuct PV/T system, solar panels are mounted on metal collector panels that channel excess heat from the solar array into the building’s HVAC system.  As a result, this system, which is part photovoltaic and part thermal, can generate electricity and put heat to use when heat is needed in the building.

Conserval Engineering estimates that its SolarDuct PV/T system can reach a total operating efficiency of over 50%, thereby reducing the ROI time frame on the entire investment.  With a faster payback, companies might just be more inclined to invest in a SolarDuct rooftop system, even without favorable state and local incentives. 

These models further explain how the system works:

The company anticipates that its cogeneration system will help make PV investments financially approachable in standard commercial, industrial, and institutional applications.  Further, the use of these all-metal collectors for mounting the panels might just standardize installations and conserve costs associated with that portion of the investment, too.

    This is really cool. Along the same lines of killing two birds with one solar panel, you should check out the solar tracking skylights by Solar Tracking Skylights, Inc. They don’t really win props for a creative name, but the product is pretty awesome – they increase natural lighting, which cuts down on energy use, plus they provide a low-cost solar solution. More info and a 3D model of the skylight is in a Top Ten Green Building Products supplement we at Sustainable Industries just released. There are 3D models of all the products that you can play with – check it out here: http://www.sustainableindustries.com/resources

      Amy – thanks for the link to your resources page. I didn’t realize you had all those guides there. I need to look into that Solar Tracking Skylight you mention. We’ve featured the SunTrackerOne here previously, which seems like it could be similar technology.

    cool! yep, it definitely seems similar. there’s also a thermal roof in the 3D guide that’s pretty fun to tinker around with. :)
