You can get a combo kit with 100 w panel and controller for pretty cheap. Just get something decent like renology or victron. Mounting the panels and running the wires will require drilling into the roof and chasing the wires. think about where you'll mount the controller in close proximity to the batteries. Many times it's easy to tuck in the back of a cabinet. Just use the proper sealants like dicor to seal up the holes in the roof. I am sure Stir crazy will be on here shortly to provide better details at mounting and using solar.
