This is a most excellent place for technology news and articles.
Start putting solar canopies over all these goddamn mostly empty parking lots we have everywhere. Completely wasted space otherwise and it’d provide some cover from the rain for people coming and going from their cars.
Plus you'd lower the temperature of the vehicles, reducing air conditioning and decreasing fuel/battery use, which would further decrease emissions
No one ever brings this up, but the heat island effect might be diminished? Not sure how the math works out there.
Possibly? But either way, cooling the panels will increase their service life with a slight net increase in output as well. It should reduce the heating of parking lots by as much of the power it makes.
Or abandon the min parking reqs so developers can build something else there. But also solar panels where we actually need parking space
Most of those minimum parking requirements are based on bullshit anyways.
Yeah, build something other than a parking lot, and put a solar panel on top of that! 🧠
This is one that seriously gets me as to why we don't do this more, it would make so much sense. Obvious benefits are power generation, but also when you consider, it would significantly reduce how scorching hot large carparks get in the sun, depending on the style of the solar canopy being built it could also massively reduce the amount of water flow onto the ground reducing some wear on the tarmac in addition to some hazards.
Also for places like the UK where we typically don't have huge amounts/extended periods of snow, as long as the canopy is sufficiently designed for the additional weight, you could ameliorate the need to salt the car parks, once again increasing the life of the tarmac.
It would also keep people's cars much cooler, in the sun, and make things generally a lot cooler below the canopy.
"Its too hard to maintain."
"What if someone hits the pole holding up the panels?"
"It costs more than clear cutting a forest to put the panels in." (True story)
Lots of bullshit reason.
That’s where a properly functioning government would be able to step in. Parking lot taxes are going up x%, but if you install solar panels, you get an x% tax break.
That and add a steep tax for single purpose solar fields.
It’s not that it’s too hard to maintain, but that in order to make sense it would have to be cheaper than building and maintaining the solar panels on some larger and less valuable patch of land 30 minutes out of town.
I work in municipal development.
If it costs a quarter-penny more to build a better product, a developer will do anything they can to avoid it.
I've had them flip out and demand to the City Manager that I be fired because they had to paint parking stripes. More than once.
This seems to largely be a "retelling" of an original story from NPR from 2021. The original has significantly more information from actually interviewing the owner of the project.
This is harder than it looks.
See those rows of crops? On most farms, you need to be able to drive a tractor through them. I don't mean a riding mower, I mean a giant thing that pulls a tool that's working on 5-10 rows at a time doing things like tilling, seeding, fertilizing, harvesting, etc. If there's big metal pillars every row or every other row, that tool can't be used.
Thus, as pictured, those kinds of panels can only be used on a farm that's not using large multi-row agriculture machinery. That means it'll work for small family farms but not the large ag operations where this sort of tech could really kick ass.
What I would really love to see is more solar over commercial parking lots. That means a million little projects instead of a few huge ones, but think about how much surface area that is overall. It's huge.
The key to doing that is twofold- 1. create a few cookie-cutter designs for the frameworks that can be tweaked for individual projects, and 2. remove red tape from their implementation.
It should be possible for a business to buy off the shelf plans for such a thing, have a local engineer tweak them for the project specifics, and then have a local contractor do the installation, and have this happen in under 6 months.
As it stands, building anything above where humans will be involves a nightmare of engineering and insurance and liability, making it cost-prohibitive for most companies. That needs to get easier. I believe every parking lot should have solar above it- that not only will produce a ton of power, but it'll keep the cars cooler in summer.
There are plenty of crops that have to be tended and harvested by hand: Most green leafy vegetables for example.
This opens those fields to dual use alongside power generation, which might reduce agricultural use of fossil fuels, and provide shade for field workers which is especially dangerous with climate change raising heat levels.
So we need levitating solar panels. Got it.
Might be a crazy idea but maybe they can just use smaller tractors. I'm not sure if we have the technology to build Smaller tractors. But since they are needed maybe there could be a Lot of R&D to make a tractor that fits under the space available in these installations.
Small tractors are easy. The issue is efficiency. The big tractor is big because the tool it pulls behind it covers ~10 rows per pass. You can easily build a small tractor that does 1-2 rows per pass, but that means you need a lot more passes, which means doing anything takes a lot longer.
Agro-solar is a win win. Solar is the fastest and the most economic energy to deploy.
Agrivoltaics is the combined use of solar panels and agriculture under the panels that together use less energy and produce more crops. It can also provide shade for livestock.
As this is not mentioned, is it possible to extend the system by collecting rainwater falling on solar panels ?
The rainwater would fall off the slanted panels and fall onto the plants.
This is so cool!
