We generated more than 10.5 kwh on Sunday, which is charted above. It's interesting to see that at least some power is generated over the course of 12 hours, even when the sun is very low, and on very rainy days, like Tuesday.
We generated 34 kwh in our first six days (below), running at a pace of 170 kwh per month; that seems to be in the right range, as PV Watts says I should generate 181 kwh in April (http://rredc.nrel.gov/solar/codes_algs/PVWATTS/version1/US/Maryland/Baltimore.html). (I may have to double-check the inputs there).
