I don't mind buying from china, as long as they're not irreplaceable essentials (like oil). Solar panels and -batteries are fine as long as they meet safety standards and don't have backdoors, and for all the fearmongering that Chinese made tech has backdoors in them, nobody seems to have found any evidence of that. And since it's electronics, any chip and any software can be investigated and taken apart by both amateur hackers and government funded (IT) security bureaus. Nothing. Unless I missed it, but I don't think something as big as that would go by quietly.
