My STXR2500 just passed 30,000 kwh lifetime production. I installed it 3/14/03, which is 3100 days ago, so the long-term average production has been 9.68 kwh/day. It's fed by 28 SX120 panels facing due south at 24 degrees. The cabling averages 30 feet of 8 awg. for each rack of four panels. The daily net power produced was 2.9x the label rating of the panels.

I only once saw it hit 2500 watts, on a cold clear day after a storm with some sharp-edged clouds helping.

I live only 1/2 mile from the Pacific coast, with morning fog common, so the less than usual production isn't too surprising. As long as my meter runs backward during peak hours I'm happy!
