The energy it takes to do that is significant. Often exceeding the energy gained in the winter.

I'm thinking if the sun can warm the panels enough for a thin layer of ice to slide off, then it can't take that much more energy to make a thick layer slide off.

It does. Even at 0F, you'll see snow melting on the roofs in winter.

We have to make power somehow and they all want to use said power. It mostly just boils down to nimbyism at the end of the day. They are just unaware of (or don’t care about) areas like cancer alley where we dump all our mining/refining/processing/etc. in an already impoverished area that can’t push back the same way wealthy neighborhoods with social status can.

> and they all want to use said power If I were to hazard a guess every person complaining would happily suffer the 'consequences' of a solar farm not being near their neighborhood. It really should be a no brainer compromise to zone solar as industrial so they're not near where people live. There's in practice infinite amounts of land you can get zoned like this. Living to electrical noise sucks in a way living need…

People put solar panels right on their roofs. Noise is not a major issue for solar. It is hardly an issue at all.

Yeah, in Oconto county Wisconsin, residents are all up in arms about a solar farm going up. It's the poorest county in the state and would bring in much needed money. The arguments against it are "this destroys farmland", "who will clean the snow off of it in winter", "I don't like how it looks", "static electricity will kill the crops around it", "it will raise the temperature of the surrounding area", "you can't re…

You could ask them why they grow so much dang corn then? > 1/3 of corn is used for fuel - https://ers.usda.gov/data-products/chart-gallery/chart-detai... > Corn raises temp & humidity - https://extension.illinois.edu/news-releases/corn-fields-add... > Corn destroys farmland & requires very high fertilizer & pesticide inputs, plus extra fuel to to apply all those - ask any old farmer but this one has a lot of sources…

Normal people understand this. The people of northern WI are a bit challenged.

Solar panels == shade. Any companies deploying solar in this manner (parking lots, pedestrian trails, bus benches, etc..)

Locally Michigan State is covering all their parking lots with solar panels. The added advantage is that since you're car is parked under them you don't have to clear the snow off. https://ipf.msu.edu/about/news/solar-carport-initiative-earn... But what I haven't figured out is if they have to broom them off after a snow or just wait until the sun melts it. By the time I am around in the afternoon time they are alway…

No idea if anyone actually does this. In theory, you could forward-bias the panels with an external power supply. That should generate infrared light at the band gap, which should melt the snow.

It might be enough to just form a thin layer of water, so the whole mass of snow slides off.

This gets proposed a lot. The reason it isn't more frequent is due to the cost of the structure to hold the panels & risks of people running into them. It would be great if these costs could come down. Parking lots, animal pastures & other areas could be protected & create energy at the same time.

They also light on fire occasionally

> Males who transition to female are not males. They are female/women. It is already not permissible for men to compete in women-only sports. This is precisely the point of contention.

I understand the point of contention should be that but sadly when we dig into these discussions it often becomes clear that’s not what it is actually about. So frankly, I won’t sit here and stand for this user saying these women aren’t women. They can talk about physical advantages/fairness in sports in good faith without erasing their identities and saying “it’s a fact that biology says they’re not women,” which is…

For panels in northern climates, if the tilt is fixed or just seasonally adjusted (i.e., not tracking the sun), we often will bias towards a bit more vertical tilt than mathematically optimal to encourage snow shedding.

Let's test this idea and assume for a moment that sex exists on a spectrum. What specific criteria are you using to place individuals at different points on this spectrum, and how do you calculate if an individual is closer to one end or the other of this spectrum compared to another individual? Which evidence supports these decisions? Given that most species reproduce sexually, how does this concept work for the vas…

Sure! It's pretty trivial. I'm going to assume at least a high-school knowledge of math, since I'm assuming you're unfamiliar with terms like bimodal distribution, categorical data, et cetera. If you're interested in learning more, this kind of thing generally falls under statistics. So this boils down to the question of essentially "if everything is on a spectrum, how can we categorize it?" and the answer basically…
