Intro: Combining Small Solar Panels
I have a trickle charger that I rarely used. Then I have a solar panel to a motion security light, that the motion sensor to the light quit working.
So I combined the two panels to increase the output. Using silicone, I attached the panels to a piece of thick plexiglass.
I hooked up the panels in parallel and the connector and lead from the trickle charger to a set of battery clips.
The main lead is hooked up to the plug that was originally plugged into the security light.
The combination easily out 9 to 10 volts.
The plug on the lead from the panel to the security lights fits perfect in the plug on my O2 Cool fan.
I have the fan pulling cooler air into my camper through an storage tube that was intended to store a small sewer hose (which it never has stored a sewer hose).
The plug also fits perfectly into a rechargeable flashlight that uses a 6 volt dry cell battery.
Found one thing that was odd.....
The wire leads running from the black panel are crossed. The wire with the white stripe is negative. so I had to change around the leads coming from both panels and both connectors/plugs
