Why can't I use this sensor as Solar Panel Production (doesn't show as an available sensor)

Why can’t I add this sensor to home assistant Energy dashboard? It doesn’t show on Solar production energy (kWh) dropdown.

Running home assistant 2021.9.6 and sensor is defined like this:

template:
  - sensor:
      - name: solaredge_energy_this_year_template
        device_class: energy
        state_class: total_increasing
        state: "{{ (states('sensor.solaredge_energy_this_year') | float / 1000) | round(4) }}"
        unit_of_measurement: kWh
        icon: "mdi:solar-power"
