Model for thin films


The Stuttgart firm has launched the new version 8.0.1 of their INSEL software that is designed for professionals and end customers to understand, plan, monitor and visualize renewable energy systems. INSEL provides a meteorological database of 2,000 international locations as well as simulation parameters of all solar modules, inverters and thermal collectors that are available worldwide. The new version includes measurement data of thin-film solar cells, in addition to that of crystalline solar modules.

As the shape of the IV curves of thin-film cells has a stronger irradiance dependence than crystalline cells, they require more parameters for the simulation process. The failure rate of simulating thin film modules has been reduced to about zero percent with the new analytical model according to the company. Instead of six, the new model can calculate ten parameters. A 30-day-trialware version in English is available on the website.
