Solar panels have a way longer lifespan than what's usually said (20 years is what people calculate with. But at that point they're not broken or anything). They lose a bit of efficiency but that doesn't really matter for already installed systems... So what this means is that this power source is here now and it will basically stay forever. Replace the odd panel here and there, but the power curve that we have massive amounts of power during mid day, pretty much regardless of where you live is here to stay. It's a miracle really. I suspect the effects of it on the economies and society haven't even begun to show.

The US could become a green powerhouse overnight if we just blitzed solar installations. Rural towns could become energy independent and fund their local government with solar power production, large cities could buy power from their local area and provide repair and materials recycling. In rural areas power bills could become a thing of the past. Households that use less than they produce could generate income from net metering. Farms could power their entire operation with panels above or adjacent to crops, selling excess power as well as produce.
Instead we have greedy old fucks fighting over the decaying corpse of the fossil fuel industry and trying their best to stop the world from turning. Fucking infuriating.
Just do like France and start installing over the US' endless, endless seas of parking lots. Property owners would eventually turn profit. It saves on parking lot and car damage from sun/heat exposure. Seems like a no-brainer but no one is doing it.
There must be reasons why there aren't at least SOME areas are doing this, since it essentially doesn't exist. Can't be JUST the cash layout on the panels, and US reluctance to do green energy. Is it power grid issues? Insurance problems somehow? Something else (serious replies only, no lazy "because capitalism / they are stupid / etc")?
The upfront costs aren't negligible, they're the only reason I don't have solar panels on my roof right now. It's not just panels themselves, it's installation and wiring and making sure it plays nice with grid power and making sure it won't catch fire and all that. They aren't huge costs and they're certainly recoverable in the long run, but that doesn't mean much if you can't afford to get started.
Not saying that there's no upfront cost, but in the US people buy 60k dollar cars on credit that lose half their value in the first year or two.
So I think it's more a problem of priorities, and choosing loss of value over future profit.
You say it like that's a common thing in the US. Maybe it's more common here than elsewhere but it's not typical. Most people who buy cars don't get new cars.

Up-front costs are a factor but can't be the only one. Although I'm focused on the solar over parking lot case specifically.
Parking lots are a bit of a puzzle. This is speculation, but I suspect the slow uptake has a lot to do with the contractual relationship between the landowner and the business operator. Sometimes businesses own their own land, but I think in the US this is more an exception than the rule. These can be decades-long lease agreements that stipulate how the land can be used and what can be installed, and I bet that the installation of power infrastructure would have to be hammered out in a renegotiation with each party trying to get an advantage over the other.
I think that is incredibly likely to be another factor
There must be reasons why there aren’t at least SOME areas are doing this, since it essentially doesn’t exist.
They aren't yet common but more are built all the time and they are far from non-existent.
You probably don't realize how many of them there are. Here's a link showing dozens of Solar Canopy projects done by just Lumos Solar. There's dozens more companies across the United States doing these kinds of projects you just don't hear about them. As examples did you know about the the solar canopy parking lots at Dell, Intel, Cincinnati Zoo, and Rutgers University? There's also solar canopies in Omaha, Kansas City, Chicago, and Denver that you probably have never heard of.
Don't feel bad for not knowing about them either; these kinds of project simply aren't newsworthy unless they are tied to some major project or entity.
The real reason you don't see parking lot solar a lot is that it's far more expensive than just slapping some panels up in an empty field. For parking covering, the structures supporting the panels are taller, so they need to be more robust. You also have to worry about increased maintenance. Someone is going to ram a support pillar a truck once in awhile. There are far fewer people driving through empty fields. And whether to repair damage or simply to clean the panels off, there are advantages to open fields. Instead of having your panels scattered across a hundred small parking lots, they're all in one spot. Much easier to arrange maintenance and cleaning. Not only do you save the drive, but bigger facilities can invest in cheaper solutions like panel cleaning robots.
The parking lot structures have the advantage of not taking up any additional land. But the construction and operation costs are sufficiently magnified that just building panels in an empty field is more cost competitive. Hell, if nothing else, panels in remote farm fields are maintained by rural labor, which tends to be cheaper than labor in expensive cities.
We also have massive, massive untapped pumped hydro capacity to use as storage. It's literally just the oil lobby. Nationalize the remaining oil companies after allowing them to spin off their refineries and chemical processing plants (still useful, can also use biomass feedstock). Not rocket science, just intractable politics (because of Citizens United).
Farms could power their entire operation with panels above or adjacent to crops, selling excess power as well as produce.
they don't do this already?
Canadian farms run 100% on solar for water pumps and sprinklers.

If we converted the land used for growing corn, specifically to be made into ethanol fuel, to house solar panels that alone would create more energy than the US is currently using. Then you can plant cash crops that need more shade, but have higher profit margins, in the same fields as the solar panels and still maintain the land's agricultural importance
I don't think you're thinking this through. How would the corpos turn a profit between now and when those panels are up? You're not thinking about the short term loss of profits. It could render and entire family vacation without champaign! Downright unamerican.
I heard about that in a technology connections video. Apparently it's eight times the current US electricity consumption, even though those fields are mostly in the higher latitudes.
I'm using second hand panels I got for free. They are 25 years old, made in Germany and they are still at +95% health. They produce 255 Kw per panel, modern panels are twice as efficient. But still, this is pretty impressive.

I'm doing my part! I have a small set on my house and it pays for almost my entire bill in the summer.
Same. I'm working on electrifying everything. I have geothermal HVAC, a heat pump water heater, and an EV running off the solar panels. Only the gas stove remains.
Gas stove was one of my first - when it’s time, definitely consider induction. My pots and pans really do heat up faster than gas! (And way faster than electric resistive).
It’s a good kind of strange that my stovetop itself never heats up.
As soon as I bought my house I installed maximum solar panels and battery on it. Through all of summer I kept both my air conditioners on day and night at 23 degrees and never once imported from the grid, only used solar and battery power.
The credits I get from the power company for my excess exported power is pretty paltry, so I do what I can to use up my own solar. I bought a large food dehydrator and have started dehydrating my own hiking foods like soup, protein bars, biltong, ect and making little MRE-style hiking food packs. I have a spidergro grow light which I might use to set up a little greenhouse and grow some more delicate culinary plants some time soon too. Plus I can run a big stack of home lab servers and stuff at home without needing to consider the power cost. It's pretty great.

Yeah same. 400W on the greenhouse. Pretty sick backup power. Would probably run the freezer with the batteries I have, as it is just runs fans, stereo, irrigation, chicken heater and water barrel heaters in the winter. But would be good enough for charging and a few other things on a pinch. Tempted to DIY for the house cause this system was so easy. Need to get an electric car to use for battery storage first though. Thinking of getting an old Nissan leaf to make into an off-road/hunting toy.

Energy supplier hate this, because the sun shines on every roof. They can't sell us their product anymore.
And petro-men hate this as well, because their business model is collapsing. That's why they are shrieking so loud.
Well yeah, solar is free energy.
It wasn't a foregone conclusion until recently. Thanks to the engineers who made it incrementally more viable over the years.

Solar electric and heating is the ultimate because you can definetly cool down the panels and keep your well insulated house nice and warm.
In general solar electric is great because you can use it for anything, heating, cooling, battery charging, chemical processing, etc.
Good! Take that sellers of energy. Nobody owns the sun. Where's your profit now?
Inb4 Sam Altman talks about Dyson Sphere-ing the sun to power his Orphan Crushing machine.
Have I gone mad with power?
No, it's a perfectly reasonable plan to dream of stealing the Sun.
Sun in intermittent. Let our salespeople introduce you to our ASSymetric Hybrid OveralL Energy plan: for a modest monthly premium, you will be allowed to draw a quota of electricity from the grid that you can replenish by sending back your own excess of production. Of course sending back too much won't increase your quota. If you exceeds your quota by drawing too much, a reasonabe penalty will be applied to your rate, as an incentive to moderate your production and make the world greener.
On a side note, you'll be happy to learn our revenues have kept growing this year, and you can rely on us for years to come in our very fruitful partnership.
With love!
