Description

Rated electrical characteristics are within from +10% to -5% of the values measured at Standard Test Conditions (STC). Irradiance of 1000W/m2, 25°C cell temperature, and solar spectral irradiance per IEC 60904-3. Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than reported at standard component test conditions. Accordingly, the values of Isc and Voc should be multiplied by a factor of 1.25 when determining voltage ratings, conductor capacities, fuse sizes, and size of controls connected to the module output.
