I think the problem might be that our car parks just aren’t all that big, and there’s other infrastructure that needs to be built to accompany DC grid sources like this, they don’t just plug straight in.
There’s lots of normal sized car parks dotted all over, very few of them are really of any particular size, and the ones that are are usually multi storey car parks to save on footprint anyway.
Bonus effect is it helps keep customers cars at a cooler temperature
Plastering agricultural land with parking lots and suburban sprawl is a crime against humanity. This wasteful land use needs to end.
I’ve done a ton of biking in my area over the last 15 years, and it’s been depressing seeing how much former farmland and unused wild area is getting gobbled up by the fucking McMansions and “high 700s” McTownhouses. The townhouses are especially sad - like, you’re out in the middle of fucking nowhere (no town in sight) and yet you’re jammed in with neighbors on both walls?
Efficiency doesn’t care how big your country is, sprawl would be as inefficient in Cyprus as in Russia, you spread your services and infrastructure over an unnecessarily large area, to huge economic and environmental cost, and forcing people to rely on a car to move around
It also has to be protected from vandals and morons protesting it.
Also, just for laughs, make the support bars too low for modern pickup trucks haha!
Not all agriculture is done in full sun. Ginseng, coffee and other important crops do best in shade. And you can put the panels up on grazing land. The critters often appreciate the shade which approximates a savanna environment.
And things like vertical bifacial solar panels can work especially amazingly on grazing land that isn’t suitable for crops.
Counter-intuitive as they may look, they actually have a number of benefits:
- The panels face east and west, meaning they generate peak power in the morning and evening, which corresponds to peak demand => less need for energy storage to bridge the gap between the mid-day peak in production from traditional PV and the aforementioned morning and evening demand peaks.
- The panels are vertical, which makes them easier and cheaper to maintain, as dust, snow, and rain naturally shed from their surfaces.
- The panels get less direct energy during mid-day, keeping their surfaces cooler. Turns out cooler solar panels are more efficient at converting light energy into electrical energy.
- The arrangement lends itself very naturally to agrivoltaics, which means you can derive more yields from a given piece of land and use less land overall than if you had segregated uses.
- The compatibility with agrivoltaics allows farmers to diversify their incomes streams and/or become energy self-sufficient.
Solar fencing produces 3% more yield and 30% more revenue than rooftop.
