KEEP YOUR CALIBRATION CURRENT! The solar reference cell certification service from VLSI Standards allows users to keep their solar reference cells certified and traceable. Service Description The Solar Reference Cell Certification Service is a process by which customers submit their own solar reference cells to be measured and certified. The certification is accredited by NIST and is traceable to both the National Renewable Energy Laboratory (NREL), and to the International System of Units (SI). Each solar reference cell is individually calibrated. Spectral response data is also included. Each cell will receive a Certificate of Calibration and an individual VLSI Standards serial number for historical reference. The Certificate of Calibration reports the certified values and uncertainties of the measured values, and is written in accordance with ISO 17025. It documents the basis of traceability of the reference cell and can be used as part of a quality program complying with ISO requirements. Product Specifications SERVICE SPECIFICATIONS TIER 1 Certified quantities Isc, Voc, Imax, Vmax, Pmax, Fill factor, Area, and Efficiency.
