The Solar Thermal section is very manufacturer specific, and therefore you would need to gather the test report for the Solar Collector known as the EN12975 Test Report. On there you will find all the information to enter into the software.
This is for both the flat-plate collector and evacuated tubes. For the cylinder information including the solar coil area will be provided by the manufacturer of the cylinder.
