My system just went over four years old and we just hit 75 MW produced.
If you look at only electricity saving and nothing else. Then we are on track to have the system pay off at 5 years and a couple months.
Now we use mini splits to heat with using solar power and not natural gas that saving really adds up.
We drive our Chevy Volt 20K EV miles a year and save not buying gasoline.
We offset our electricity every month.
If you take account for all these savings the array paid for itself in two years.
Any way you look at it we are happy with our solar array. I am glad to see others installing solar.
Over the last four years my system average is 51 Kwh a day produced.
