- functions to estimate parameters for popular PV module models, including PVsyst and the CEC ‘5 parameter’ model
- a new model of the effects of solar spectrum on PV module current
- code to access weather data from NOAA’s Integrated Surface Data network

PVLib version 1.3 can be downloaded for free at pvpmc.org and is released under an open source software license. POC: Josh Stein.

]]>GridPV Toolbox is a fully-documented set of Matlab functions that can be used to build distribution grid performance models using the open source distribution modeling tool OpenDSS. The GridPV functions are useful for interfacing OpenDSS and Matlab to perform sophisticated analyses and graphically representing information from simulations. A set of functions is also included for modeling PV plant output in the OpenDSS simulation. The toolbox contains functions for overlaying distribution feeders on satellite images using GPS coordinates.

GridPV version 2 was recently upgraded to include the following new features:

- Updated MATLAB help menus for GridPV and a new user manual, including 20 new pages of documentation
- Updated to use new OpenDSS System object
- Uses the newest Sandia Wavelet Variability Model (WVM) for PV modeling
- 25 new plotting features and functions

The documentation and toolbox are available for public download. POC Robert Broderick (6112).

]]>The MOSAIC program focuses on the design of technologies and concepts for a new class of cost-effective, high-performance micro-scale concentrating PV (micro-CPV) technologies integrated into “flat plate” solar panels to improve their efficiency and cost. This micro-CPV approach addresses the constraints of conventional CPV, which, while highly efficient, has not been widely adopted due to its high cost, large size, and expensive solar tracking systems. Project teams will address these limitations by developing innovative materials, micro-scale manufacturing techniques, panel architectures, and tracking schemes. The MOSAIC program also includes a Small Business Innovation Research (SBIR) award category. POC: Anna Tauke-Pedretti
