    Solar noob

    As the title suggests I know nothing about solar power.

    Got myself a 120w panel to attach to my roof rack on a permanent basis.

    What else do I need.

    p.s. remember keep it simple I have no idea at all.

    Do you know if it has a regulator at the back of the panel?

    If you want a good simple but excellent reference book, then grab a copy of Collyn Rivers book called 'Solar that Really Works'. He also does one on Camper Trailers that explains it all as well. Find it online at his website.

    However, the simplest system just needs the panel, regulator and appropriate cabling and lugs to link it to your battery. Your 120W panel is a good minimum starting point for most, but your required solar capacity really depends on your usage (how many items draw from your battery).

    You will need a Charge Controller AKA Solar Regulator for that panel.
    A 10 amp one will suffice unless you plan on adding more panels.

    I find that 120 Watts of Panel more than covers my camping needs but everyone is different

    Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

    We have 2 50l fridges and a coleman hot water on demand unit. We camp for up to a week and a half at a time.

    If needed we will get a folding panel and this controller thing comes in 10/20 and 30 amp.

    I agree with FNQGU. for a simple set up you will need a regulator and cabling. You need to add up how much amps you are drawing from all your equipment as well as knowing your battery capacity to start with. Just remember that you only get about 5 - 6 hours a day a good light in ideal conditions to calculate your amps in from your panel. Yours will make approx 36amp/h per day in ideal light conditions with that panel. If you are using more than that then add another panel. Don't let your battery run down more than 50% or it will shorten the life of the battery considerably. If you get the book it will explain all this in lamens terms.

    Not convinced mounting them on the roof is a perfect setup.
    reason being you need to park the Patrol in the sun for the Panels to do their thing.
    Any fridge inside will be working harder to remain cool, something to think about.
    If you have them free standing atleast you can "CHASE" the sun better during the day.

    Have to agree with 3d here. My bro ended up removing his from his roof rack and uses brackets now.

    He was not getting sufficient charge mounted under the rack directly pointing upwards.

    Under the roof rack though is really not ideal because once you get a little bit of shadow on the panels they really drop in their efficiency.
