Question

Could a lead barrier protect us from the solar wind?

Answer

Yes. In fact, that is a technology which has been tested on the International Space Station to keep the astronauts safe if the solar wind should flare up. In fact, they don't tend to use lead because lead is so heavy and obviously, weight is very important in the International Space Station. But a thin layer of metal or plastic is enough to deflect the particles.
