> solar panel installed doesn’t disappear if China changes their stance
Most countries have days to, at most, months of imports of oil in reserve. In contrast, a panel embargo wouldn’t have disastrous effects for years. But reliance it is the same. If you’re dependent on Chinese panels, China can cap your energy growth at whim. The degradation will be slow thereafter, but present nevertheless.
Using foreign panels for anything other than bootstrapping domestic or allied production would be the EU repeating its follies first with Russia and then with American LNG.
Stopping new panels in some hypothetical scenario is very different than stopping fossil fuel delivery when ch can stop ongoing energy production - it not even in the same timescale of problem
What are the alternatives for Europe? Continue to import oil and gas? Have some of your most important economic inputs price and supply controlled by the dumbest egomaniacs alive?
Nuclear? Good luck building it on time and on budget. Also where exactly are you getting that Uranium from? I’m not necessarily against nuclear I just don’t think there’s much you can do in five or ten years to move the needle with Nuclear.
Wind? Actually a good option as it has a strong domestic supply chain.
Solar? Buy China’s cheap panels as long as they are selling. If they stop selling figure out how to do it yourself. It’s not some big mystery how panels get made, China just had the foresight to invest in the scale required to drive prices down.
Coal? I mean at least it’s local. But solar + batteries are either beating it now or will be in the next few years if the same trends that have held for the last 30 years continue for the next 2-5. So you’d be investing in a more expensive, dirtier technology for what end?
There is no world where you get to not make a decision and the risk just disappears. I think renewables have the clear advantage here and have very manageable risks.
> Also where exactly are you getting that Uranium from?
Uranium can be stockpiled relatively easily (france had 4-5 years of uranium stockpiled). Since it is about 1% of the energy cost, that’s pretty inexpensive.
Also, uranium comes from suppliers on 4 different continents, there is little chance that it becomes unavailable overnight.
Importantly, it used to be Germany which had all the expertise, until the CDU government destroyed much of the German solar industry over night. It's funny how everyone always talks about Germany stopping Nuclear energy but nobody ever talks about the fact that subsequent German governments destroyed the renewables industry twice (and they are talking about it again), largely due to lobbying from the coal, Nuclear and car industries. Definitely an interesting what if
The EU has the talent to ramp local production of panels and batteries in years, which as the parent said is how long a panel or battery embargo would take to really cause a crisis.
I mean the EU has ASML, the Large Hadron Collider, and ITER, among other things. There is no engineering talent problem.
I’m more concerned that we do not have the supply chain. Like, sure, we have people who can build solar panels, but are the components local? I wouldn’t expect so, we would very likely import from china. Developing effective supply chains takes decades, it’s not really something you can do right away with the level of precision required by modern technology
Power electronics shall never be connected to the "Internet".
Any such installations of solar panels, batteries and the like must be interconnected only in a private network without Internet access.
For remote monitoring and control a proxy mini-PC must be used, to which one should use an authenticated and encrypted connection.
For any competent person, this is trivial to do today, to ensure that even if some electronic device includes a backdoor for its vendor that backdoor cannot be accessed.
If there exists any kind of wireless connection provided by the vendor for a device, it must be disabled, e.g. by removing any internal or external antennas. Unlike wired connections that can be filtered externally, wireless connections cannot be secured.
My Chinese built inverter functions just fine without Internet, but I'd have to take over doing what Amber Energy are doing if I lost access to the cloud.
But that's residential scale: at grid scale these things wouldn't be online in the same way anyway.
Not the panel itself, but the firmware of the solar panel charge controller and inverter that's connected to the Internet because there's an app to monitor the system. I wouldn't bet that there aren't remote kill switches deep inside that firmware.

If they couldn’t do it it’s a political problem.

But there is some valid concern around internet-connected PV / battery power electronics getting bricked remotely.
Power electronics shall never be connected to the "Internet".
Any such installations of solar panels, batteries and the like must be interconnected only in a private network without Internet access.
For remote monitoring and control a proxy mini-PC must be used, to which one should use an authenticated and encrypted connection.

It can stop working properly if the chinese panel is encryption locked to a chinese cloud which is the case with many residential installations.
My Chinese built inverter functions just fine without Internet, but I'd have to take over doing what Amber Energy are doing if I lost access to the cloud.

Not the panel itself, but the firmware of the solar panel charge controller and inverter that's connected to the Internet because there's an app to monitor the system. I wouldn't bet that there aren't remote kill switches deep inside that firmware.
The panels and controllers are mostly interchangeable are they not?
They've found some of those in the wild. They weren't that deep.
