Step 20: Adding the solar panel

Picture of Adding the solar panel
I wanted the solar panel to act as a charger but its only designed to charge 12V lead acid batteries like you would find in a motorbike or ATV. I'm going to look into building a 24V charging circuit for the next version.

For now the panel acts with the voltage regulator to act as an emergency backup power system for the camera in case something goes wrong. If the main battery dies or power is somehow lost the system will switch over to solar for the camera. That way I can at least see where the tank is and whats happening to it. I mounted it with adhesive backed velcro which is great stuff for mounting things you might want to remove often.
