I am thinking of getting some portable solar panels to power my pop-up camper and had a few questions.

The panels will not be mounted to the camper because of the hassle of wiring the pop-up portion of the camper. The new Four Wheel campers come prewired for solar but mine is too old for that. Right now I have a gasoline generator I plug into the AC inlet on the outside, a automobile battery charger I plug into to the AC outlet on the inside, and then the DC output from the battery charger goes into my camper battery.

I think all I need is a portable solar panel that has about 100w AC output and plug that into the AC inlet on the outside of the camper. It would either power AC directly or DC through the battery charger and battery.

I am planning on putting the solar panels either on the ground or propped up against the truck or a tree. How should I secure the solar panels from theft?

Any suggestions as to brand or models of solar panels? I have been reading the reviews on Supertopo but the only ones I saw were for household use or for charging small portable devices. Where should I go to see reviews of RV solar panels of about 100w? What online retailers do you reccomend?

Any RV parts site should have what you need.

I have 4 30w rigid Goal Zero solar panels and two of their big battery packs. If you are an employee in the govt. or outdoor retail you can get Goal Zero stuff at 50% off retail through www.promotive.com. I use my system for heating and cooling, lights, stereo, charging cameras and have used it once to recharge my truck battery when I left the headlights on all day. Some of their smaller panels I have not been too pleased with but their Boulder 30 panels that I have are great.

Batrock, thanks for that info on Goal Zero and Promotive. A couple of questions, how fragile are the Boulder 30s? How do you transport them? Do they have anywhere you can pass a cable through so you could lock them up?
I would have to find somewhere to put them in my camper or pickup truck when not in use.

They are pretty stout but the corners are hella sharp and have cut my leg on them a few times until I taped them up. There are holes that are used to connect the panels that you could pass a cable through if you needed to. For transport I stand them on their sided and wrap them in a thick towel. I'm pretty happy with them overall.

for 110 ac you will need a power inverter.

You will also need a solar controller to prolong battery life.

check ebay, get monocrystaline. I see some German made 100watts currently there. panel brands are not all equal performance.

I'm a solar contractor and I just happen to own an older Four Wheel Camper rig. Adding solar wasn't that hard. You can drill through the aluminum frame behind the rear hinge and fish the wires from fridge area. It's pretty hard to protect the hole so I used boat cable which has thicker insulation although it's more expensive and a bit tougher to find. The top was easy. Drill a hole and fish the wire down the bay. I poked a small hole in the fabric at the rear and used a fish to pull the wire. It helps if you remove the vent frame. Be patient with the wire, it took me about 2 hours to get it from the top to my charge controller.

Try to buy a good quality panel. Sharp would be good but it's getting hard to find quality panels in the 100 to 130 watt range without paying through the nose. Do not buy from Costco, Lowes, RV stores, etc, etc. Be careful buying from Ebay. Lots of used, old technology panels on that site. If you're lucky you live near a lake with big houseboats. Find out who does the solar. If the're like me they will probably have good used panels for sale. Houseboat owners have more money than sense and frequently upgrade perfectly good systems when the guy on the next dock gets one better then theirs.

For this type of application I like Morningstar charge controllers. 5 year warranty, good performance, price and customer service. I've installed quite a few....

If you buy new panels don't mount them with L brackets. Some panel manufactures are refusing to warranty panels with holes drilled in the sides.

Worry about the weight. The top gets harder to open with a panel mounted on it. I'm going to add a strut lift system when I replace my current panel with a 175 watter.
