Steady-State Sun Simulator for thermal Collector and Photovoltaic
Our steady-state solar simulators are an ideal solution for a range of applications. They are primarily used for light soaking and performance measurements in photovoltaics, and in solar-thermal applications to measure the performance of solar collectors.
The solar simulators feature safe operation, as well as easy assembly and maintenance. Their modular construction, featuring a large number of individual lamps with outstanding radiation characteristics, not only ensures excellent spatial and temporal uniformity of the light intensity, but also the option of expanding the system at a later date. We can plan a solar simulator especially for you in accordance with your requirements.
Solar simulators are an indispensable means of determining the performance of solar-thermal collectors and photovoltaic modules independently of weather conditions. There are two fundamental approaches to solar simulators:
- Steady-State Simulator
The fundamental advantage of steady-state simulators is their simple, cost-effective, and robust design. In the photovoltaics field, these simulators also enable testing of cell materials with longer response times than crystalline p-n silicon material. In addition, the nominal operating cell temperature (NOCT) is very easy to determine. For collector testing, there is no indoor alternative to the steady-state process. The Mini-SuSi was developed as an offshoot of the large simulators. This self-contained unit offers an inexpensive option for providing a stable solar-spectrum light source for the testing of photovoltaic cells. Like the larger simulators, this device is suitable for the research field, as well as industrial quality assurance and training environments.
Our simulators are designed acc. IEC 60904-9 for terrestrial PV modules.
Measurements acc. EN 12975-2 for efficiency of solar thermal collectors in stationary state are possible (cold sky is necessary).
