  • Spectral Evolution provides accurate, affordable spectroradiometers for testing, measuring, and classifying continuous solar simulators. Rapid and accurate measurement of electrical power output and related characteristics of PV cells, modules, and panels is critical to solar manufacturers to ensure that their products will perform to promised levels during their outdoor life. Solar simulators are used to test the cells, modules, and panels under a set of standardized conditions. The solar simulators mimic the natural sunlight that the panels will see when installed. The solar simulators themselves are tested to be sure they meet ASTM and IEC standards for three areas: spectral match, spatial uniformity, and temporal stability. Spectral match classifies a solar simulator based on the amount of light (irradiance) it outputs and assigns a Class A, B, or C status based on performance measurements in wavelengths from 400-1100nm. Uniformity measures the irradiance at different point in the area covered by the simulator. Consistent output must be measured at different points. Temporal stability measures performance over time.
  • In solar cell, module, and panel manufacturing there is a need to classify pulsed solar simulators for testing and verifying panel performance. The SR-1901PT spectroradiometer is ideal for quantification of pulsed solar simulators as part of a manufacturer's quality control process. Pulsed solar simulators are used to test large solar panels at a fraction of the cost of continuous solar simulators. Before a solar simulator can be used, it must be monitored and classified to prove that it can provide consistent information on panel or even cell performance. The SR-1901PT is ideal for classifying pulsed solar simulators. Compact and portable, it is easy to take to any measurement challenge and can be quickly set up and used. It operates with a convenient integral phototrigger. Running our DARWin SP Data Acquisition software, the SR-1901PT includes spectral match reports for AM1.5. All scans are saved as ASCII files for easy use with most 3rd party software programs for additional data analysis.
