They use Pt elements that you would be able to read with a PTC Bricklet 2.0

Unfortunately. this ist not true.

The CMP11 pyranometer outputs a 0 to 20 mV signal, this cannot be measured with a PTC Bricklet 2.0. The PTC Bricklet 2.0 is designed to measure the resistance of a PTC sensor. Also there is no Bricklet that can measure such small voltages accurately enough for this use case.

There is the SMP series of pyranometers that output a 4 to 20 mA signal, that can be measured using an Industrial Dual 0-20mA Bricklet 2.0:
