Utility-sector policies can enable or hinder solar markets. Clear policy and regulation translation and implementation protect market stakeholders and reduces the “back and forth” during project development and at other times. Sandia is active in disseminating technical information to inform those who make policy and design regulations. One approach is through training. Educational seminars raise […]
Modeling PV system performance involves a number of steps that are shown in the figure below. A more detailed explanation of each step is presented below the figure.
Irradiance and Weather – This step involves choosing a source for defining the site’s expected irradiance and weather conditions. Typical sources include: typical meteorological years (TMY), satellite-derived data, […]
Consistent appraisals of homes and businesses outfitted with photovoltaic (PV) installations are a real challenge for the nation’s real estate industry, but a new tool developed by Sandia National Laboratories and Solar Power Electric™ and licensed by Sandia addresses that issue. Sandia scientists, in partnership with Jamie Johnson of Solar Power Electric™, have developed PV […]
This Web Demo model is a simplified “player” version of the Photovoltaic Reliability Performance Model (PV-RPM) currently in development at Sandia National Laboratories (SNL). The PV-RPM is built using the GoldSim™ Probabilistic Simulation Environment. The PV-RPM allows the user to define a PV system (inverters, modules, tracking, etc.) and select or input weather data, and […]
