On-site Power Generation
The Green Proving Ground program has commissioned Department of Energy National Laboratories to perform real-world measurement and verification of the following technologies in pilot installations in federally-owned buildings. Preliminary technology assessments are available below as PDFs.
Preliminary Technology Assessments
PV with Solar Water Heating > This “turnkey” system combines normal roof-mounted photovoltaic panels with thermal heat extractor panels mounted beneath them, thereby collecting both electric and thermal energy within the same footprint. Findings available in 2014.
Honeycomb Solar Thermal Collector > 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. Findings available in 2015.
