Watching Youtube I noticed a few people hosing down their solar panels with water in the hot sun.
I wanted to find out what kind of effect this was having on the efficiency of my panel setup.
This was the start of SAM.

I have a 15w panel I used on my solar truck project and a 60W panel by Aleko from Amazon.
I'd like to build a system to track the sun and monitor the output, as well as automate some outdoor things.

In some further testing I managed to gain about 3W with a 10C drop in temp 50C to 40C
Cooling might be an option during the summer months, the panels easily reach 50C in good summer sun.
I could build a gravity system or a pumped systrem, but with winter around the corner, I should work on other aspects of the larger picture.
