Tests of output volts and amps produced before and after removing the blinking LED. Both overcast sky and bright sunshine. I hook up a DC to DC Buck Converter and explain it a bit. I run a USB charging port, I charge a camera and a cell phone. I use the panel to make a batch of colloidal silver. I test the panel with a simple solar charge controller. I charge a 12v- 3ah lead acid battery. This solar panel is not weather proof because it’s designed to be used on the dash of an enclosed vehicle.
