YOUR units are all screwed up
10 KW PV. Power=energy/time
You say 10 kw for 5.25 years is 93.3 MW. Maybe 93.3 MW-HRS which is a common unit for total energy produced. I don't have a calc in front of me or I would do it for you.
It is assumed that power generated is watt/hours in the number.
The power produced by this particular system has been recorded so it is set in the record. At $.36/kw the system has produced $33,588.00 worth of electricity. The CO2 and the number of trees saved is per Enphase.
