2 yrs exactly as predicted, no shading issues

I had 38x 190W panels installed which in the Seattle area was expected to produce about 7500W. In year one (bad weather year) they produced 7200W, in year two they produced 7500W. I've never had a problem with the panels. No cleaning has been required. I have ideal southern exposure with a lake to the north which I think helps a bit as well. Before installing I tried shading the panels and measuring Volts & Amps and was quite surprised that they don't just turn off as expected. The voltage dropped off, but it still passed the current, so shading really hasn't been an issue. In fact, I had to cover it in several blankets before it would truly shut down.
