Flexible Solar 40 Watt

My first Scamp Solar Panel arrived. For now I'm just placing it on the roof to see how it behaves. Though I knew it would be a tenth of inch thick, it's amazing to see how thin it is. The backing is a thin sheet of aluminum. Of course the connector is thicker than the panel.

Norm,
Can you tell us again where you got the panel? Thanx
Never mind, I think I found it-Sunflex- correct?
What about the tape-where did you find that?

Solar Panel and Tape

You are correct about the solar panel, it is Sunflex. I tried it and it seems to work. It's nice that it comes with wiring and a water tight connection. The packing was very secure.

Tomorrow I'll get my controller out and see how it actually works charging the battery.

I haven't figured out how to get the wires into the trailer yet. I suppose I could drill a small hole through the roof into a closet.

Sunflex Solar and Alternative/Renewable Energy - About us

I bought the tape on Amazon. I was buying my great (double meaning) niece a camera and saw the tape and bought it. I'm not sure I bought an appropriate tape but I'm going to give it a try on something else first.

Amazon.com: Scotch Permanent Outdoor Mounting Tape, 1 Inch x 450 Inches (4011-LONG): Office Products

If I don't find it acceptable I'll get something stronger.

That tape looks like it may work and I'm intrigued by the solar panel.

Norm,
I use a boat fitting designed for where the coax antenna cable penetrates the hull.
Most marine stores carry them and there only about $5.00.
The base is about the size of a .50 peice and has a compression fitting with a rubber gromet the wire goes through to seal out the water.
I use rivets to attach the base to the roof.
If the wire is to small for the fitting I just stuff the compression fitting with butyl putty.
John

Thanks, I'll take a look for one.

you got the solar panel direct from sunflex? the picture on their site shows a different size for the 40 watt, looks like a square unit versus what you have will this fit on your rock shield thats where i want to place my next panel

another suggestion would be to use industrial velcro all four corners then when you travel take it down i have installed a permanent 80 watt panel to my roof and have two marine ports one on front and back for a portable panel that i move to when its needed i want to get a flexible unit for my rock guard use the velcro for a temp install and take down when traveling i have the hardware set up for both the front and rear window so i can change the rock guard position for shade you can use pvc pipes at different lengths to catch the sun better to angle the rock guard up or down

Sunflex

We did get our panel directly from Sunflex. They were pretty quick getting it here and it was packaged really well.

I agree that the Sunflex picture looks relatively square. In reality the product matches the specs shown under the description of the 40 watt unit. It's closer to 2 to 1 than 1 to 1, actually 1.7 to 1.

I believe a single panel would fit on the rock shield. We plan to have two of the 40 watters and they would not fit on the rock shield.

We are generally opposed to doing temporary mounts. We don't carry coolers, chairs or anything like that inside the trailer. Our goal is for everything to have a place and not have to be moved to set up or live.

We like our setup to be as quick and simple as possible. Next year we'll be on the road for 300 days, meaning that we'd probably have to setup 70-100 times. For this reason we'll probably permanently mount our panels. As well we don't carry a ladder to make temporary roof installation a possibility on the roof. We depend on occasionally borrowing a ladder as we travel.

We do like the thinness and lightness of the panel. We don't think it will interfer with the slippery-ness of the Scamp. I will say that though they are called flexible panels, they are not nearly as flexible as the UniSolar panels. You almost have to think of them as sheets of 0.050 thick aluminum panels or greater. They bend but are not floppy in any sense.

I am seriously considering the marine fitting idea, plan to check them out when (if) the rain stops. (I had hoped to give the panel a test today but it's been a downpour all day.)

I have never considered rear mounting the rock guard but I do use plastic pipes with bungees down the center for rock guard support. I've occasionally considered window awnings because they look easy to do but neither of us consider them a necessity. We haven't had them in all our RV years, we simply close the curtains when necessary.

Thanks for the thoughts, it lookslike the marine fitting is a go.

I think the thickness dimension you quoted is off by a factor of 10. The Sunflex panel in the link you provided is listed as being 2.5mm thick. Assuming the web site is correct, then 2.5mm equals 0.098 inches, rounding off that is one hundredth of an inch thick, or a little less than the thickness of 3 sheets of paper.

Woops, I stand corrected, when rounded it is a tenth of an inch thick.

here is a picture of the plug and panel with the connector they twist connect forming a tight seal i have one port on the front and one in the back with 20 feet of cable to use if I'm in the shade. I don't need this when I'm at the beach

two addl pictures from another scamp owner who showed me her set up

i also have a vertical wind generator that's just about ready for use so i will be at over 200 plus watts my rig is total green solar, propane and soon wind

i use the same plug and adapter for my wind generator

Solar Panel Under Test

I taped the panel to the roof, wired it thru a solar controller and began testing it. Though it's very overcast, it's producing 21.5 volts open circuit right in line with it's specification.

You can see I simply used blue painter's tape to hold it down for the test. We get an afternoon sea breeze and I wouldn't want it to blow away; it is very light.

I mounted it in the long direction because it sits flatter and when I add a second panel there will be no interference with the rivet caps.

The purpose of the test is to determine that the panel works as specified and to determine what temperature the roof reaches.

I took a closer look at the construction and the back of the panel is a thin piece of Lexan or the like, followed by a thin sheet of aluminum, then a thin insulating sheet, the cells and finally covered with a sheet of clear Tedlar. This is all bonded together into a watertight unit. The Lexan makes up the bulk of the thickness.

Here it is taped to the roof.
