PV module imaging and quality assurance

Posted on October 29, 2019 by gregorykimball

Near-infrared imaging and lock-in thermography provide detailed, complementary information for studying the performance of PV modules. In previous work, we described how to extract both local efficiency and nonuniformity characteristics from high-resolution images (as low as 22 μm/pixel). Near-infrared images … Continue reading →

DataGridViewPrime

Posted on March 23, 2016 by gregorykimball

C# WinForms offers a suite of fully-featured controls for building responsive, event-driven user interfaces. However, there is limited native support for data visualization and the existing tools show poor performance when plotting >100K data points.

My solution to this problem is DataGridViewPrime, a class extension of DataGridView that includes functions to Save, Copy and Explore the data source bound to the control. The features are accessed though a new context menu created for the control.
