Panel setup for a camp for three months?

I couldn't figure out how to lift that 250W monster on the roof with just a ladder. Thought of lifting it on the ropes and pulleys, but then decided to call neighbors at the camp. They didn't mind, snowbirds have nothing else to do.

Yes, people normally install more than 100W on RV roofs. Some of them are tilted, and can be build similarly on the ground. In fact, much easier, - on the ground you just stake it down with pegs or anchors. No messing with tapping screws and sealant. With so many solar farms in rural areas there should be commercial racking solutions too.

Do you mean a temporary structure on the grounds of the Renaissance Fair for week end use,
You can't spend the weekend in your RV ?

You can get far more than 100 watts on the roof.

(BTW I put my 225w panels up on the roof myself)

Flexible panels are not an easy material to build anything. Go rigid.

I don't see a problem building a rack of 1/8" or 3/16" aluminum angle, with vertical arms on the North side and horizontal struts connecting the bottom of the arms with the front of the panel. Assembled on screws or pins, and panels fastened with the same. Horizontal struts would be staked to the ground. Shouldn't take more than a few hours to assemble every time.

Theft possibility? With prices of big panels approaching prices of 4x8 plywood - not very likely to find somebody THAT desperate. Use rivet-nuts and tamper-resistant screws if you're worried about this. McMaster have some very tricky screws that fit only their proprietary screwdriver.

I've seen this kind of rack on a top of a van, was made of rusty steel slotted angle and cheap fasteners. The whole contraption was attached to his roofrack as I recall.

Westend here has made something along these lines (of aluminum and stainless hardware) on top of his trailer, ask him about photos.

Of course, if you will have the whole weekend to build it every time, you can build it from 2x4 from a local store.

I hope you realize that each 250W panel weighs 42 lbs and requires 3 people to lift it to any roof over 6ft height - 2 people lifting and one grabbing it from the top.

Buy a used two wheel trailer and build the solar system on that, then you can always lock it to a MH or a camper.Plus when you are there you can move it around to get the most sun.
