Flat panel mounting and water pooling
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.

Re: Flat panel mounting and water pooling
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.

Re: Flat panel mounting and water pooling
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.raysun wrote: ↑Tue May 24, 2022 1:08 pm Our solar panels are mounted essentially horizontal, on a roof with less than 3% pitch.

Re: Flat panel mounting and water pooling
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.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.
Will these last 20 years in the sub-tropics? I'd be surprised.

Ray, you even made their testimonial page. Creative product.

Re: Flat panel mounting and water pooling
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.

Re: Flat panel mounting and water pooling
if you have a 3D printer you could print them yourself.
here are couple similar clips that you can download and print:

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.

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

Re: Flat panel mounting and water pooling
I think there is printer that can print synthetic bacon or meat made in a lab.
this is a bit related to it:

this is more on target:
