We went with solar panels, but not from Solar City. We went through Apex Solar Solutions, and our solar panels are made by the Hyundai group. After two months, our electric bill is significantly less than what it was in the past years, but it really matters how your house is situated. You've got the option to lease or to outright buy. It's important to do your due diligence on the company installing, as well as seeing what the warranties and guarantees are on the panels. Don't take the salesman's word for it, but demand everything in writing. Should you go for it, get names, numbers and contact information, and don't sign anything until you research the hell out of it. You will not be able to escape th electric company and go off grid (unless you already are) but you can sell back your excess electricity and either get a check at the end of the year or some other deal they're offering (I forget what the options were.)
