How much does solar power panel usually cost?

I was thinking of having some solar panel installed on our rooftop and was wondering if it would be worth the cost? The house is located in Sac, Cali. The panels would face the sun 12 months out of the year and in the summer roughly 14 hours of straight sun. Just looking for a rough idea without having to go through whole of signing up to loads of different contractors before getting a quote.
