Enphase recently tabulated the results of their first survey. This survey went out to installers who have installed at least one Enphase system.
Newcomers and Veterans Agree on Enphase. Enphase has proven valuable to both solar first-timers and solar old-timers. According to the survey, our largest customer group did their first solar installation in 2009 and the second largest Enphase customer group has been doing solar installations for more than five years.
Most see significant energy harvest gains (click on chart above). Of the installers tracking energy production, 90% observed an increase of more than 5% with Enphase, and 12% of installers noticed an increase of more than 20%.
There are many reasons to consider Enphase. 100% of installers said energy harvest played a role in their choice to use Enphase, but installers had a number of other reasons for choosing Enphase, with ease of design/installation and ease of monitoring ranking high on the list.
