Don't even start with science stuff when it comes to Star Wars. Absolutely EVERYTHING is wrong in these movies in that regard, so it's no use talking about it.
Anyway, because I'm in the mood, I'll answer your question. I didn't see the movie and don't know how exactly that blocking should take place. But in any case, you won't kill a solar system with that. Not even a single planet. Imagine the sund would be blocked, earth would be fine for several years. By "fine" I mean that a lot of the population would die, but anyway. Earth wouldn't be TOTALLY fucked. The planet produces heat itself, which is enough for life in certain regions. On top of that, you can't block gamma rays, so the earth would still get energy in some form. But even if the sun simply disappeared, earth wouldn't go down instantly. The heat would go down with time without a sun, but we're talking about centuries at this point at the very least. So the question is, do they block the sun for good? Or just for a limited time? Say they are blocking the sun for a whole year. The planet would get dark as fuck, sure, but other than that, not too much would happen. If they block the sun for good, yeah, the planet is fucked - in about 10,000 years.
Blowing up a planet is it's own beast. There's no turning back if you do something like that, that's it. Aaaaaaanyway, it's as good as impossible. To literally blow up a planet like earth with a weapon that turns mass perfectly fine into energy (a nuclear reactor has an efficiency of about 1 %, so yeah...) you would need the masses of 10 jupiters - at the very least. It just ain't happening. It would be better to just change the course of a big ass asteroids, of which are plenty in pretty much every solar system, using a gravity tractor.
edit: Oh, and screw both solar power and windmills. Way too inefficient. Nuclear power is the way to go, it's best for humans and nature. We should use our reactors from today until we got nuclear fusion figured out, if you ask me.
