An installed 10kW PV system generating power for about 5.25 years has generated 93.3 megawatts and this equals 64.5 tons of CO2 and about 1550 trees - per the Enphase Enlighten web monitoring site.
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.
