Meh

While the panels have been OK, with the new larger inverters from Enphase I would likely get higher rated panels. I would consider another brand to ... these are OK ... but not great; I was hoping for a little better performance. Highest output for any one day has dropped from 29.600 kWh in 2011 (when I installed) to 29.104kWh (2013) or about a 1.7% decrease so it's inline with expectations.
