solar power contractors

Is it worth buying solar power for a home?

My dad is retiring in a few years, and he is looking into this. I know that this is what one of my teachers did when he retired, but I don’t really want to ask him how it’s been goin ;)

So, what are the pros and cons of buying solar power for a house?

P.S. I live in Canada and I live on the bay, so it is only sunny like 50-60% of the time.
