Honeycomb Solar Thermal Collector
Preliminary Technology Assessment
What is This Technology?
A solar thermal collector generates hot water, which can be used for service water heating (SWH), space heating, or process heat. This product employs a ‘honeycomb’ design that promises greater heat gain on the energy-collecting surface and thus higher efficiencies than traditional flat-plate or evacuated tube collectors. The design is also projected to work more effectively in diffuse light (during hazy or cloudy days) than other solar thermal collectors, making it particularly attractive in cold and temperate climate zones.
Why is GSA Interested?
EISA 2007 requires that 30% of GSA’s hot water demand be met with solar hot water (SHW) if life cycle cost effective. This technology promises significantly shorter projected paybacks than the incumbent technologies for buildings with consistent hot water loads.
