Sandia defines solar variability zones

Sandia Labs has defined solar variability zones by modeling solar variability across the country using a combination of ground measured and satellite derived solar irradiance measurements. The zones represent the magnitude of high-frequency (sub-minute) solar variability—changes in available sunlight—at each location. Photovoltaic (PV) installations in locations with higher solar variability can, all else being equal, [...]

Sandia Labs releases wavelet variability model (WVM)

When a single solar photovoltaic (PV) module is in full sunlight, then is shaded by a cloud, and is back in full sunlight in a matter of seconds, a sharp dip then increase in power output will result. However, over an entire PV plant, clouds will often uncover some modules even as they cover others, [...]

Sandia Labs conducts PV research as part of ARPA-e MOSAIC program

Massachusetts Institute of Technology and Sandia National Laboratories have initiated a collaboration on Wafer-Level Integrated Concentrating Photovoltaics that reduces the complexity of tracking needs. The team’s innovative approach uses wafer-level micro-concentrators to significantly enhance sunlight concentration onto high-performance III-V micro-PV cells. The concentrator is also a diffuse solar radiation collector, allowing the technology to operate [...]

Sandia Develops Stochastic Production Cost Model Simulator for Electric Power Systems

Sandia has developed a software toolkit that uses stochastic programming to perform power system production cost model simulations. Named PRESCIENT, the software produces probabilistic forecasts automatically from deterministic historical forecasts for load, solar, and/or wind power production and their respective actuals, using a technology known as epi-splines. An example of a probablistic solar forecast [...]
