Did a series of "before" pics this morning. Supposed to have a crew out here this afternoon to clean the array. First time I've paid to have it done. Not cheap at $400, but worth it in terms of performance and longevity of the array. I'm going to guess we'll see about a 10% increase in output, but that's just a guess.

"Rain" was supposed to be enough to keep them clean, but the pine pollen is pretty sticky. On the closeups, I can still see where I couldn't reach a couple of years ago when I used an extendable RV washing brush to clean them the last time. Ideally, I'd get on the roof and do it myself, but I'm getting to the point where I feel that discretion is the better part of valor, and I'll let someone else do it.

I'll take another series this evening and see how they did.
