had a 14.1 kw system installed in May 2011 using Sunpower panels and Enphase micro inverters M120.
the first year produced approx 9,000 kw/h of power, that was for 8 months. and using 6 hours of good sun daily 14 1 kw /hr x 6hrs sun x 240 days = 20,000., my 9,000kw/hr was less than 50/%
2012 , 2013 and 6 months of 2014 the yearly output gets worse and I am embarrassed to show you the numbers..
2015, 2016 and to date in 2017 it would appear that 60% of my ENPHASE MICRO INVERTERS M120 have some some type of failure issue and of the remaining 40% that indicate they are operational ,my production is showing 1kw / hr.
I am about to take action with my installer, who is aware of my issues, and at this point will wait and see what ENPHASE is going to do about my situation.
I roughly estimate that over the 6 yrs of operation I should have produced at a minimum 150,000
my utility meter shows that my total production is 26,000, I will be updating this review after I get feed back from ENPHASE.
FYI my installer has informed me that ENPHASE may or may not pay the labor costs to this warranty claim, I will also keep you posted on the outcome of this issue., you can contact me by e-mail ynotynot81@hotmail.com... read more
