2010 was our first full year of solar (installed Dec '09). April and May were our most productive months--but, here in coastal San Diego, we had one of the least sunny summers EVAR. A colleague told me a week ago or so that we'd already had more sunny days in January than we did in July (fewer daylight hours, of course, but still).
Your colleague may be right about the number of sunny days, but here in Irvine, close to Rt 405 but still coastal, solar generation wasn't bad. Though last July was the cloudiest July we could ever remember, we still generated over 90% of our best July production in the previous 3 years, and August was our best August of the four years for which we have records.
The January just ended had lots of sunny days and we had our second best January on record, but June, July and August last year each beat January by a wide margin.
