Resetting the watts up meter this morning, everything was covered in a coating of dirt from the storm that moved through. I have a pic but with Internet out to the House, I'm not sure how to easily post it to a site linkable from here using the iPad. The mottlled coating of grime looks like it would block half your amps.
When I cleaned the Unisolar, the output was down less than 10% from all that grime. I guess I will not be so concerned about cleaning the PVs up on the roof.
10:53 AM (local sunrise 7:14), mostly sunny day with a few scattered clouds, 3.905 Ah so far this morning, 2.67 A, 12.49V and 33.3 W.
