The term "run" was actually a question of how much does it cost? I should have been more specific. I use too much slang.


Well featured 30 amp is $375. I assume the 20 amp would be less but not that much. WAG $300-$325.

It is going to be up high anyway. It is also adjustable for angle, so I can use it to deflect the wind. I can also leave it level if I choose to. Either way, it needs to be strong enough to withstand the wind forces going by it. I'm not attaching it to the roof of the camper.

I'd be careful with that. Perhaps there's a wind load spec on the panel itself.. not the frame, the cells themselves.

If I use it also as a wind diverted it won't be at a real sharp angle. I just need the frame strong enough to support it.

Sorry to hear that one of the panels was damaged. I can't wait to see the numbers you get. Was the free shipping a limited offer?

The free shipping on the second panel wasn't a limited time offer. FedEx charges them the same amount whether they ship one panel or two panels. That is why I chose the second panel. Shipping is $100 for one panel. The panel was only $212.

Exactly my experience with the shipping, two are as cheap as one. That is a great price on the Sharp module, BTW, sorry to hear one was damaged.

Glad to hear that I wasn't the only one thinking of using a module to deflect wind. I was thinking of mounting a module on the rear of my truck cap to accomplish the same thing. After looking at the amount of work involved with terminations and my expected use, I put that project on the back burner. If you look at the better modules, you'll see that the ratings for wind and impact resistance are very high, higher than typical residential roofs, even. I think they can accomplish this by the acetates used in the module construction. FWIW, I've had the module on my TT tilted while in storage. It has been in 60 MPH gusts, endured a brief light hail event, and is still going strong. I made the 4-way tilting brackets from architectural 6061 aluminum, for the most part, nothing thicker than 1/8".

Here's a picture for inspiration:

My tilted panels have been in 40+mph winds with no ill effects.. except scaring me to death!

BTW, why is this thread still in TT?

westend, I like your solar panel mount. I'm doing something similar where I am making an entire 1-1/4" aluminum square tube reinforcement frame that my solar panel aluminum frame will mount to on all sides, and then I am making it hinge off of my aluminum trailer bracket. My tilt will only be a maximum of about 30 degrees down when traveling down the road so it isn't real extreme. The reason I'm making the extra frame is to keep the solar panel from flexing since I'm mounting it above the trailer tongue.

I finally have the 1-1/4" aluminum frame attached to the bottom of the solar panel. It really stiffens up the panel. I have it partially mounted to the trailer, but I won't have a chance to finish it for a couple of weeks. It seems like it will give me a good aerodynamic shape up front since I can adjust the angle.

I have two 250 watt 24 volt Sharp panels and I am probably going to try one of the Eco Worthy MPPT controllers. I'm thinking about hanging the second panel on the side of the trailer so I can swing it out for shade while also using it for more solar capacity. Has anyone used two of these controllers, one for each large 24 volt, 250 watt panels?
