Solar Energy

I live in an area that does not get a chance to see much sunlight. Granted, for our couple of months of summer we have a lot of sun exposure but really it is very minimal throughout most parts of the year. Is there something that I can to use off grid solar for energy through my house? Is there a way to store excess energy and use it during a time that I really need it? I want to increase my dependency on renewable energy instead of on something that will not be along long term unless we do something about it now.
