Data acquisition of solar radiation and calibration

Bachelor’s thesis is focused on description sensors of solar radiation, main principles, function and reason of rise mistakes and faults during the measurement. At the end of thesis is performed calibration of two cheaper pyranometers SG002 from Czech producer by comparison to a reference pyranometer CM11, which represent the secondary standard. Calibration consists of two main parts. In the first part is necessary to determine offset and in the second part to specify an instrument transferring constant between the correct and calibrated value
