Eco-Mod Skylight Makes 60% Solar Efficiency Available Now

While most solar companies are struggling to squeeze low-20s efficiency from a solar cell, one company has found a way to more than double that number. BrightPhase Energy Inc. has combined the benefits of a few different sun-catching methods to create a low-cost and simple energy solution.
The trick is a system of three technologies - photovoltaic, thermal, and daylight - which provide electricity, heating, and reduced need for lighting. Branded Photensity, the module is basically a teched -out skylight. This idea makes so much sense, it's almost obvious, but it doesn't look like anyone else has been able to pull off such a hat trick yet.
Future versions of the device are planned to incorporate a heat-driven cooling system and wall mounting capability. The company says the "tri-generator" has an installed cost of less than $2 per watt and return on investment in 6-9 years without subsidies and much less with.
The company has just signed a tenative deal with renewable energy developer Appalachian Energy. The North Carolina firm will help BrightPhase test and demonstrate the system, with a 200-300 module install for one of its customers.
If it sounds like a nice add-on for your green remodel, you'll have to wait. BrightPhase has positioned this technology for large commercial buildings. But if all goes well, maybe they'll develop a McMansion size.
