How much will it cost me to install solar panels and is it worth it?

My home is all electric and the rates just keep going up, up, and up,
I paid 0 for Jan – Feb this year and froze my tail off keeping it that
low. If I install solar panels, will it cost me less then what I’m paying
for electric? If you’re currently using solar panels can you tell me what
the pluses and minus’s are for going this route.
