LAKE FOREST, Calif., April 19, 2010 — Chroma Systems Solutions Inc. is contributing to the photovoltaic (PV) industry with the introduction of its Solar Application Soft Panel. This software tool uses the proprietary 63600 series DC electronic loads to generate PV module I-V curves and track their maximum power point.
Through an intuitive graphical user interface, it enables users to record and analyze a module's electrical characteristics and output behavior without having to configure any hardware. Combined with the 63600 loads, the company has developed an out-of-the-box test and diagnostics solution for any production, quality laboratory or field installation environment.
Analyzing module I-V data at various stages of the PV process can aid in assuring product reliability. This software provides and reports valuable information from early signs of degradation that may develop over the course of the PV module's life.
The software takes advantage of the measurement accuracy and multiple power ranges found in the 63600 series DC Loads, whose compact and modular design provides portability and power. These electronic loads operate at low voltages, eliminating any need for external bias sources and minimizing data losses.
The maximum power point tracking function uses proprietary loads to keep the PV module operating at maximum efficiency. Analyzing a PV module's ability to output maximum available power over an extended period of time and in various climate conditions can also provide good design feedback, contributing to product improvements. The algorithm used to achieve maximum power point tracking is based on the “incremental conductance” approach, which uses the fact that the slope of a power curve is zero at the maximum power point.
The software continually adjusts the electronic load's constant current set-point to maintain the PV module's output power at this point, while dynamically adjusting range during abrupt sunlight condition changes to ensure optimal measurement resolution.
