How can I hook up a generator?

I am building a green home – solar panels on the roof, etc. I was wondering if it was possible to use an exercise bike to generate electricity in connexion with a generator. If so, does anyone know how to do such a thing? I am looking to store any electricity generated to help light my home.

What is better, generator or solar panels for camping? We have just bought a camper van whats best?

We are looking at getting a solar panel for camping what does it involve? how much do they usually cost? Are they hard to transport? Are generators easier?
