What are the advantages and disadvantagesof using solar power?

Mainly what are the plus/minuses of SOLAR THERMAL DISHES but any information you have on SOLAR POWER would be a great help!

Thanks, 10 points best answer!
Oh, and by the way!
I kinda mean using solar power for companies like as a alternative to using coal, not just for your own use at home by setting up your own private solar powered devices!
