That may be causing mismatch, bringing down your energy production, especially if you don’t have microinverters.

Here is a picture of what I'm dealing with: Wed, 21 May 2014 21:15:30 GMT https://community.ecohaus.me/t5/Solar-Solutions/Drop-in-solar-panel-energy-production/m-p/380#M28 Gina 2014-05-21T21:15:30Z https://community.ecohaus.me/t5/Solar-Solutions/Drop-in-solar-panel-energy-production/m-p/382#M29 Oh, that is a lot....<BR /><BR />Easy solution: Clean off the solar panels with water. A simple spray of water from a garden hose will do.
