Typically, solar panels perform best when facing south with a slope between 15 and 40 degrees.  There are a number of mapping services that will help you determine if your roof is suitable for solar.

The amount of money you can save with solar depends upon how much electricity you consume, the size of your solar energy system, if you choose to buy or lease your system, and how much power it is able to generate given the direction your roof faces and how much sunlight hits it. Your savings also depend on the electricity rates set by your utility and how much the utility will compensate you for the excess solar energy you send back to the grid. Check the National Utility Rate Database to see current electricity rates in your area.
