Solar Light offers all hardware required for cutting edge PV Cell Testing and Research applications. Our state of the art single output Solar Simulators produce Class A Air Mass 1.5 Emission Spectrum to accurately replicate full spectrum sunlight, with 1 sun output intensity. They can also be quickly and easily configured by the user to provide UVA only, UVB only, UVA+B, or custom spectra optionally. Models are available from 150W / 1.2″ (3 cm) to 1000W / 6″ (15.25 cm.) These precision research-grade instruments are specifically designed for testing photovoltaic cells in accordance with the latest ASTM, IEC, and ISO laboratory standards. Our comprehensive PV Cell Testing Kits arrive with everything required to immediately begin testing, including the Simulator, Power Supply, advanced Data Logging Radiometer, PMA-Series Full Spectrum Class II Pyranometer, safety glasses, and more. A Source Meter and Calibrated Reference Cell are also available optionally.
