Atlas provides a special model XenoCal Solar for the PV industry. XenoCal Solar can take precise measurements for UV pre-conditioning of PV modules as specified in IEC standards for crystalline (IEC 61215) and thin-film (IEC 61646). The sensor operates at temperatures up to 70 °C and also is water-tight. Individual polynomial T compensation guarantees correct response over the whole operating temperature range. XenoCal Solar sensor measures irradiance (W/m²) or radiant exposure (kWh/m²) in the required wavelength bands:
XenoCal Solar sensor measures irradiance (W/m²) or radiant exposure (kWh/m²) in the required wavelength bands:
IEC 61215: 280 - 320 nm, 280 - 385 nm
IEC 61646: 280 - 320 nm, 280 - 400 nm
The XenoCal Solar sensor may be used to measure any light source used for UV pre-conditioning; it measures fluorescent/UV, metal halide, xenon, gas discharge lamps, or natural solar radiation. For optimum results and precision, a spectral correction factor can be programmed for each specific light source. Four commonly used light sources are factory pre-programmed.
