> Solar ... Except during the night, or winter.

Do you consider this a novel insight? A factor that needs drawing attention to? Something that isn't being taken account of, and there aren't existing solutions to?

Seriously, what are you adding to the discussion of Solar + Battery systems hereby?

In a race metaphor I'd say it is a car that has a higher top speed, is already travelling faster than competitors but is still accelerating. However it is still laps behind some competitors that had a head start.

Is that "winning"? I'd say no, but is it going to win? Yes, obviously.

Solar is not less than revolution in Pakistan. Almost every home and factory has solar installed on their roofs. More affluent houses have almost gone off grid; others are selling back to grid and others who can't afford has their own small scale 12V solar panels to run fans in the scorching summer of Pakistan to save electricity bills. It is all done by people independently without much support from the government a…

The US can have this too if it stops demonizing China.

Have what? The US uses far more solar energy per capita than Pakistan.

It is genuninely insane (in a good way!) I've encountered some degree of apprehension and disbelief from people in Western countries when I told them, that countries considered poor and backwards often are further along in the transition to renewables, and even for the everyman, installing solar and having (a usually Chinese) EV just makes sense - economically, and not only in terms of saving the planet. The markup o…

Yes, that's drive me insane, west which is biggest advocator of climate change and preaches renewable energy has not done as much as a poor country like Pakistan has done. And Pakistan is the one who is affected the most by the climate change. From September to February Pakistan AQI is basically unbreathable. Rain pattern is disturbed, winter has become shorter and summer has become longer, basically there is no spri…

It's not like Pakistan doesn't have these regulations, or doesn't try to tax solar power. It's just that the Chinese-Pakistan border is open and nobody's paying import taxes or listening to government regulations.

So the problem in Western Europe is simply that government is actually effective. This generates surprising differences with Pakistan. The government is effective at forcing employers to actually pay their employees. The government is effective at giving women their rights. The government is effective at taxing solar power.

All 3 differences are the same effect, really.

Might be a noob question, but why can't EVs have solar panels on them directly so they can get charged just by moving around? Or why can't we have SVs(Solar Vehicles)? Why do we have to use solar panels on EV stations rather than just having them on the vehicles themselves?

Aptera has this planned but not sure if they ever reach market maturity. There also was a project car from the Nordics I think. Can't recall the name though. Main problem is the large amount of energy a car needs vs what kind of surface area you have and efficiency we get. An ideal (100% effiwncy) solar cell of 5m² would still need 20 hours to charge a 100kWh battery. And we are way off on area an efficiency in reali…

Well but that would be a problem for keeping the car infinitely running with only solar power. But what about just passively charging it while idle? Cars sit idle most of the time.

The problem solar will create is that solar doesn't work for highrises. It works for suburbs. Electricity companies will be forced (more and more) to tax suburbs for nothing (for the sun, Louis XVI-style) to keep reasonable energy prices in cities.

Unless of course, cities think ahead for once and city hall gets large solar collectors (at least the physical area) along power lines NOW.

My understanding is that when buying a car you are dealing with an oligopoly. You might think that you have a lot of options, but they all come from the same source. Furthermore, big money control not only car production, but oil too. If they allow the ceo of a car company to come with such a car, they loose billions in the oil industry. So they have no incentive to do that.

New options do appear on the market like the new toyota prius with solar panel, but if you look at it you will see that they didn't even try to maximize the solar panel size. Still it gets 2 km extra range in bad conditions. Triple that and you have 6 km, in real conditions. If you use your car every other day, you will never charge it, ever. If you get average or above sun, you can drive it daily and not charge it ever. A big problem if you sell oil.

The problem with green energy is that it is very democratic and hard to control. Nobody with big money is interested in that.

To understand who controls your life, see all the draconian measures taken against electric scooters: cheap, not poluting, democratic, don't need a lot of space and so on. Everyone with money said: we can't allow that. Write defamatory articles in the media they control, pass laws against it and so on.

Especially for hot and sunny areas solar is insane. At mid day, max heat, you get the peak production and can run your AC at full throttle. That enables you to efficiently work at nice temperatures.

Heat reduces solar production, ideally you have very sunny environment with about 25C / 77F.

Marginally. Between 77F and 100F you only lose about 5%, so you still get 95% of the stated max efficiency. It’s basically negligible and not really relevant.

The energy transition in Germany sucks because they are replacing nuclear with solar when they should have been replacing coal with solar. That doesn't mean renewables are bad, it just means that turning off already built nuclear plants is bad... Which is an entirely different matter. If you look at China, they are building so much more solar than they are building nuclear, and they have no anti-nuclear sentiment. Th…

Theyre replacing both with solar.

Germany never had a huge amount of nuclear power anyway and keeping it going was expensive. Fukushima was just what pushed them over the edge.

Meanwhile in the UK rate payers are being forced to subsidize nuclear power with a guaranteed strike price that is ~4x what they have to pay for the same amount of power from solar and wind.

Remove the lavish subsidies and make nuclear pay for its own catastrophe insurance and it'd be dead in the water. Those subsidies would be put to far better use on storage, wind and solar.

Truly, you got to hand it to them. China has done the world a great service.
