My HOA is constantly getting on to the solar homeowners to clean their panels.....especially during pollen season.
Given the one across the street is a flaming lib tree hugger its become quite a source of amusement for me.
But what does a HOA have to do with washing solar panels. Are they saying the panels are an eyesore when they're dirty? Or is the homeowner on some kind of agreement with the HOA to allow him to have solar panels but only if he contributes to the power on the grid?
For what it's worth, even when my panels are covered in pollen temporarily it doesn't matter because it's spring weather. Literally the only power I pulled from the grid in my entire April billing period was the 110W constant pull I have my inverters do to keep my power company from automatically shutting me off (thinking I'd moved out and flipped my power main off if I go for a while without pulling power). So even during the brief moments I have a layer of pollen on my panels I still get more power from them than I need for what little I have to run the A/C or heat during pollen season. That's why my April bill was less than $31 -- even though I don't sell power to the grid to dry to make my bill lower.
The same for rainy weather (which cleans off the pollen). Yes on those days I get less solar, but I don't need much power anyway because the temps are almost always mild. So if I do have to pull from the grid on those days, it's not much. The sunny days tend to be the days I most need to win the battle over my power usage because those tend to be either really hot (and thus I have to run the A/C a lot) or really cold (and thus I have to run the heater a lot on those winter nights). But it's almost always easy to win those major battles because the really hot days and really cold days are almost always sunny days. Not always, but almost always. Stuff like this and optimizations I studied and tweaked on my own are why 80% of the power we need throughout the year is supplied by our solar. No natural gas bill because it's now an all-electric house. And almost no gasoline bought at the pump because most of our driving is in the EV (which we charge at home unless we take it on a trip).
But you must do the math and research on your area's weather patterns and your own daily energy consumption habits to see if it's right for you. Bonus points if after you do the install if you're a data geek and export telemetry from your solar inverters into a database and see what options in your inverters to tweak for your specific uses. That's one thing I hate about how the Dims push "green" energy at the utility level. Even for other people in my area who, therefore, are in a good weather climate like me for solar -- it's not a one-size-fits-all solution like the Dims make it out to be.
