Photovoltaic-Thermal Hybrid Solar System
Photovoltaic-thermal (PV-T) hybrid solar systems increase electricity production by cooling the PV panel and using the removed thermal energy to heat water. They use the same footprint as a standard PV system.
Green Proving Ground (GPG) assessed the nation’s first large-scale PV-T system installed at the Thomas P. O’Neill, Jr., Federal Building in Boston, Massachusetts. It provided many lessons learned in system design. It also identified a target market of locations with high utility costs and electric hot water.
