I am considering solar panels on my roof rack as well as the hood. This is great.
What panels did you go with? Can you share a link? What did you use for a controller or battery storage?
Purchased controller and panels at Harbor Freight. The panels were part of a kit: 3 15 watt panels, 2 12v flourescent light mounts with bulbs, wiring, charge controller, pvc rack. Purchased 3 kits (9 panels in all, totaling 135 watts) Kept the panels and 12v flourescents, threw everything else away as junk. Purchased a 700watt charge controller with auto low volt alarm. Waited until I got a 20%off coupon, then went to town, the panel kits were $150 each, charge controller was $50. Spent another $50 on heavy gauge wiring, connectors, etc. Bought 2 deep cycle 12v batteries for $90 each from OReilleys auto. Made custom cast roof mount spacers for panels to screw to. Another $20 or so for misc fasteners, clips, switches, etc.
I think that I will eventually go to a 6 volt battery array, series to 12v. (should have done that from the getgo)
All together, I think that I was just under $800 and about 4 hours of work
