Solar output

Hi. I have 2 x older Kyocera 80w panels controlled by Smart Solar MPPT 75/15. The Bluetooth history tells me that I receive 150Wh on average for a 24 hrs period. The solar amps appear low at always between 1.2 to 1.5a.

Do you think the panels are past their effectiveness?

How many hours of full sunlight per day? One panel may still be OK. Test the panels separately. Very carefully measure the Voc and Isc of a fully disconnected solar panel in full sunlight.
