We recently received  this e-note from satisfied customer, Kerry Kahl:
“Coming up on the third anniversary of my solar system going live and continue to love it!  It's producing right on the numbers you estimated for it – wish I'd had you cover the whole roof with panels! Have a great winter – the days are getting noticeably longer; more solar electricity!”
Kerry was also kind enough to show us the numbers. We installed 17 Silicon Energy 190w panels and a 3.0.1 Silicon Energy inverter at Kerry and husband Paul's house. Our projections for the system – turned on at “first light” on 25 February 2011 – would generate around 3,472 kilowatt hours per year. Kerry reports 3,404 kwh/y for 2.25.11 to 2.24.12, 3400 kwh/y for 2.25.12 to 2.24.13, and 3,380 kwh/y for 2.25.13 to 2.24.14.


Right on the production -- right on the money.
