6 FAQs about [Solar module project calibration]
What is a photovoltaic calibration laboratory?
As one of the world’s leading laboratories, the photovoltaic calibration laboratory at the Fraunhofer ISE (CalLab) provides measurement services in this field. We measure all types of solar cells and PV modules with precision and reliability, in accordance with international standards.
How do I know if my solar module is calibrated?
For each calibrated module a calibration mark will be issued close to the name plate. The calibration mark on the module is unique. We calibrate individual solar cells and modules, including bifacial modules, with high accuracy (uncertainty of only 1.3%).
What is a primary reference cell calibration?
Interested in Primary Reference Cell Calibrations? Primary reference cells are calibrated for in-house use and for use by other national laboratories to provide clients and partners with a path for traceability to standards.
Who is CalLab solar cells?
CalLab PV Cells was founded in 1986 with three co-workers. Today 30 employees calibrate about 2,500 solar cells and 5,000 solar modules each year. The precise measurement of solar cells and modules is of crucial importance in solar technology or photovoltaics.
What standards are used to calibrate a reference cell?
