Space based solar power is going to be a lot more expensive than ground based solar power.

The issues that it solve are distribution and night time production. I think we can solve those with a combination of various types of renewables and storage in a much cheaper way if we really wanted to.

It's an interesting technology but it's way too expensive and it might have unknown consequences. Like the other poster said, I also don't think it's a great idea to add massive amounts of energy from space to earth. It would probably be better than fossils that we dig out of the ground and turn into energy, but it's still introduce energy and thereby heat into our atmosphere.
