Price Premiums for Solar Home Sales

A Lawrence Berkeley National Laboratory (LBNL) -led multi-institutional research team, with Sandia (Geoffrey Klise, in Sandia’s Earth Systems Analysis Dept., contributing the Sandia-developed PV Value whole-system appraisal tool, among other things), universities, and appraisers found that home buyers have consistently been willing to pay more for homes with solar PV energy systems—averaging ~$4/watt of PV […]

CFD-Populated Empirical Turbine Wake Model

The DTOcean team is developing a fast-running, easy to use current-energy capture (CEC) array spacing tool that considers tidal array performance vs efficiency. In support of this effort, Sandia has been assisting in developing the device wake modeling submodule that determines a tidal turbine’s wake properties (i.e., wake growth and dissipation). Initial efforts were focused on […]

Floating Oscillating Water Column Reference Model Completed

The DOE-supported Reference Model Project was developed to provide publicly available technical and economic benchmarks for a variety of marine energy converters. The final reference model, an oscillating water column (OWC) device, has been completed. Key aspects of the Backward Bent Duct Buoy (BBDB) have been modeled and documented for public release. This model has […]

National Rotor Testbed Rotor Design Integrated Airfoil Performance Results

The National Rotor Testbed (NRT) team is examining the effect of airfoil choice on the final design of the new rotor for the Scaled Wind Farm Technology (SWiFT) facility. The airfoil family would ideally be designed to operate in the relevant SWiFT-scale Reynold’s number range, 1–2 million, and be experimentally verified. Two leading options have […]

Sandian Presents on PV Failure Analysis at European PV Solar Energy Conference and Exhibition (EU PVSC)

Sandia researcher Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) highlighted novel PV array monitoring strategies at a PV Performance Analysis and Module Reliability workshop held at the European PV Solar Energy Conference and Exhibition in Amsterdam, Netherlands. The talk was coauthored by Mike Green from MG Lightning Electrical Engineering in Israel. Under […]
