People always try to discredit #solar panels with "what about when it snows in New England????"

@mem_somerville I love it when the snow comes off ours in huge avalanches it shakes our whole house and the cats all run to the windows to see what happened (or hide in the closet, depending on the mood 😄)
I'm curious about how your layout and that data-view work. Do you have independent micro-inverters on/for each panel?
(My array is older and uses big DC series so partial shading of some panels on a string of them is a bigger hit - I've been thinking about getting it all rewired or whatnot)
@gl33p Yes, we have 35 "micro inverters" that they told us at the time solved that partial shading issue. And they've worked great for 10 years.
Our biggest problem was the first inverter got a software update at age 9.5 years that took us down for a couple of months. But our brand new (warranty covered) inverter eventually arrived and these same panels/etc still work fine.

@mem_somerville Thanks, and thanks for sharing your experience with it. AC from the panels is definitely seeming like a more versatile approach overall.

And it has been our experience (over 10 years) that the next morning most of the snow has slid off (except at the very bottom edge).
Our panels have been producing today, 1 day post-#Blizzard. As usual.
Here is the array on our roof today. The bottom row corresponds to the roof edge ones, and you can see which ones still have snow.
does this mean when the power goes out in your neighborhood that your lights are on?

@libramoon No, we don't have battery backup. You could, but we didn't install that. If we did it would be powering the house and/or filling the battery.
This was just to illustrate that production resumes the next day after even a heavy snow.

I wanted to see how we did at the end of the day. We did 40 kWh today. That's the day after the blizzard. That's a good production day.

@mem_somerville Congrats! I saw snow slide off a neighbor’s solar array this afternoon as I walked by, wish I’d gotten a video of it. It seems to me like they’re angled fairly steeply, and of course they are smooth…..so kind of ideal for shedding snow.

@grammasaurus There was one time it didn't work--one of those super hard freeze stretches where nothing was thawing and that took a few days.
But those are rare.
Usually I hear the THUMP during the storm, or shortly after daybreak the next day.

@mem_somerville and just hope you aren’t standing under it!! 🤣

@mem_somerville
also, the further north you go, the shorter the days in winter (and longer in summer). Short days + low sun means there is very little annual production to be lost from snow cover. -

I’m probably only about 3-4 hours north of you, still in New England, but just a little colder on average. When our panels get covered in snow, they tend to stay that way. 😭Still, we save thousands of dollars a year in energy costs. We burn no fuel oil, no natural gas, no propane, and one of our current cars is fully electric*. The panels paid for themselves and then some within seven years.
*We will probably have to go back to having a hybrid, for reasons

@jalefkowit i wonder if he has adhd because this is exactly the kind of dumb thing i would embarrass myself with if i were to somehow manage to 1) make it to geriatricity 2) with a giant pile of money and recognition

@jalefkowit Listen, it can't be worse than his acting.
