Product Details
To measure the output performance of solar thermal collectors (efficiency curves) and photovoltaic modules (I-V curves) independent of weather conditions sun simulators are a good solution. There are two principle possibilities for producing simulated sunlight:
- Flashing lights
- Steady-state sun simulatores
The basic advantage of steady-state sun simulatores is their easy, cheap and rugged construction. For PV these simulators make it possible to measure even cell materials with higher response times than crystalline pn-silicon. Very easy to measure is nominal operating cell temperature (noct).
And for testing of solar thermal collectors there is no indoor alternative to steady-state sun simulation. The simulators are good for development in research instituts and quality assurance in the PV module production as well as for educational aspects. Our simulators are built meeting VDE 0100 concerning safety low voltage and can be used for solar thermal collectors and for PV modules as specified in CEC Specification 101 and IEC TC 82-15 for terrestric PV modules.
As another part of our steady-state simulator family the Mini-SuSi has been developed. This complete device is a simple and cheap possibility to provide a stable light source with solar spectrum. It is suitable for measuring I-V curves of PV cells in combination with our cell adaptor for the I-V curve analyser PV-KLA.
We plan Your steady-state sun simulator for easy building at Your local site. Therefore we make a concept, based on Your requirements (enlighted area, maximal inhomogenity of irradiance in test plane), which can be realized by every electrician of Your company. On request we also offer complete simulators.
