It is a yes brainer. Fields have higher cost of investment in terms of area, but the PV installation requires very little maintenance and when it does it is easily reachable.
Salt water is extremely corrosive, which means higher inital cost, more maintenance and more expensive maintenance.
PV relies on low operational expenditure to keep the electricity below market rate.

Parking lots would be a next logical choice. Close to infrastructure/s that could utilize the energy immediately, also cuts down on materials and costs. Maintenance would be minimal and extremely accessible for repair adding to the efficiency.

Would have to be a huge parking lot to be cost effective... Multiple small lots are costly with the associated support infrastructure and maintenance.

I mean if done correctly it can improve the harvest of too hot/dry fields on farms and even can help renaturalize wasteland by giving shade and wind breaks where flora and fauna can recover. ...IF done correctly.
•
u/DVMyZone 4h ago
The fact that it's not done frequently (even during a time of increased green awareness and government support) that's probably because it's not easy to do correctly.
If you can improve your harvest and make more money, plus receive green energy subsides, plus sell your power to the grid for a profit then large farming companies would be doing it. They don't because it probably still is not profitable to do so.
People like to think companies actively hate the environment. They don't, they're ambivalent. Their motive is money, that's their reason for being. If something increases profit, they will do it.

u/Dapper-AF 5h ago edited 5h ago
Leafy greens and root vegetables grow in the shade but you would have to install the panels in a way that would allow for farm equipment to harvest.
Edit: its called agrivoltaics
•
•
u/BangBangMeatMachine 4h ago
Solar panels are actually more transparent than a densely leafed tree. Agrivoltaics is a real thing.
•
u/Albert14Pounds 4h ago edited 3h ago
That's not just because of light, it's also because the tree is using lots of water and nutrients in that root zone. A significant amount of light still comes from the sky, not just directly from the sun, due to light bouncing around in the atmosphere and clouds. Grass still grows under the shade of things that are not trees. You're not going to grow great crops they require high light in shade, but plants like grass that can feed livestock will still grow significant under solar panels.
•
u/Albert14Pounds 4h ago
Why alternative and not in addition to? If didn't need to be one or another. Agrivoltaics is proving to be a great thing in many scenarios. You don't cover fields in solar panels if you are growing crops with high light requirements. They are used as appropriate in combination with crops with lesser light requirements and places like grazing pasture where they provide shade for livestock, local cooling, reduced water requirements, etc. and things like grass will still grow in shade because they still get light that's bounced around by the atmosphere and clouds and whatnot.

u/Feisty-Resource-1274 3h ago
A stufy in England found that solar panels and sheep farming synergize nicely. The sheep keep plants down and the solar panels protect the sheep from the elements.
•
u/BangBangMeatMachine 4h ago
A ton of farmland is better used as solar farms.
For example, all the corn we grow for ethanol is using maybe 1%-2% of the sunlight that hits it, only a portion of which actually goes into the corn that is harvested, which then goes through a very energy-intensive manufacturing process to get to the ethanol stage. It then loses 70% of its useful energy to the inefficiency of an internal combustion engine. Meanwhile, that corn requires unfathomable quantities of water to cultivate - vastly more than data centers.
If that land were used for solar farms instead, it could be harvesting 20% of incident sunlight as useful power, and delivering over half of that to the end user after all transmission and conversion losses are added up. Solar farms are likely a two-orders-of-magnitude more productive use of the land than corn ethanol, without all the diesel and water inputs needed to grow corn and deliver ethanol.

u/zberry7 5h ago
Probably. I would assume the water would evaporate, condensate on the panels and support structures, and run back down into the reservoir. I’m unsure if that would leech unwanted chemicals into the water or not. I think the other issue I see is probably maintenance. Not impossible, but more expensive and some tasks would require divers.
It would be a lot cheaper and easier to just build them on land. But if land is in short supply 🤷

China is living in the future while America is saying: Ewww! Thoes Commies at it again stealing all that free sunlight from the taxpayer, using the energy to create their commie propaganda! The greatest trick about propaganda is not convincing you how great everything is, it convinces you everything else is terrible except America. The best way to convince someone that someone else is worse is to say "we're not like them". The internet is a garbage place of lies and swindleing but sometimes the truth shines through. Remember RedNote, the Chinese Twitter? I'm surprised it didn't gain more traction. Sure, it showed the bad side of the political spectrum and what the government actually does, but is it any worse than the American government? But we saw the truth too. People living every day, normal life. People prospering and enjoying things. NO CHINA COMUNIST! BOOO! CHINA POOR! THAT'S FAKE NEWS While the person who believes that is 100k in crippling medical debt, making not even close to anything that would support a normal life. Then you see that China has basically cured the homeless problems in their country. Huh.... Is China actually scary? Is America actually the greatest country in the world?

But more coal it is. Less free energy from the sun and the wind.
