Flat panel mounting and water pooling

Post by raysun »

Our solar panels are mounted essentially horizontal, on a roof with less than 3% pitch. It was simple to mount them in this orientation, and at 19° N latitude, practical for a fixed array.

A disadvantage is water pooling on the lower edge of the portrait-oriented array.

Recently, an article appeared in PV Magazine describing a small plastic clip manufactured by a company, Solarud ( https://www.solarud.eu/ ), in Portugal.

The design is very simple. Maybe too simple, but I was intrigued and ordered some to try. Installation was literally a snap, and I am happy to say they actually work.

Interesting - the article says for angles 0° to 20° - less than mine are at in summer. I have some dirt accumulation but mostly at the edge where the cells aren't obstructed, the dirt never gets much higher. https://www.pv-magazine.com/2022/05/05/ ... v-systems/

...and I do wash them eventually.

Yes, its not a big issue overall. Its not that the panels get that dirty. I'm just systemically opposed to standing water anywhere on the property due to mosquitos. They are a year-round bane here.

this are printed on a 3D printer. try to find the material used as some of the plastic used in 3D printing is not good for high temperature or exposure to sun.

I don't know their production process, but 3D printing is certainly a possibility. Being 1st generation products from a startup company, I'd expect improvements in the future. They are already teasing a Gen 2 product.

Will these last 20 years in the sub-tropics? I'd be surprised.

Its a pretty small startup, I'd think. Word of mouth is a big deal in the early stages.

I mostly bought the product because I thought the design showed some creative thinking. It seems to be taking advantage of water surface tension. Its very "Japanese" in its seeming simplicity demonstrating a complex phenomenon.

if you have a 3D printer you could print them yourself.
here are couple similar clips that you can download and print:

Can one find 3D printer material made of recycled plastic and UV protectant?

Crank us out a few of those thingiverse things and we can compare!

I have an old printer that I haven't used for a while. not sure if is compatible with PETG. I have lots of PLA filaments but they got old and brittle.
Don't need the clips for my panels and too busy with other projects.

Might be a good hobby to get a 3D printer and if you have more people around you that need the clips you could get some money back.

😆 Yes! Just what I need! A $1000 hobby to produce a $2 part. 😆

Now, if I could find one of those doohickies that could 3D print bacon, I might be interested.

I think there is printer that can print synthetic bacon or meat made in a lab.

this is a bit related to it:
