Rooftop PV Data for Better Energy Prediction Models (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption NIST's new Roof Photovoltaic Test Facility duplicates real-life conditions to monitor photovoltaic (PV) systems blended into concrete tile, slate and asphalt shingle roofs. Data from PV embedded systems and other framed PV roof modules systems will be used to validate or improve energy prediction models.
