Good morning all, I am trying to put a little project together where I used a 1 watt, 6v solar panel in conjunction with a 0.9V - 5V to 5V DC to DC boost converter. I hooked up the solar panel to a multimeter and tested it in dim lighting and it was outputting about 3.5V and 130mA. 3.3V is well within the tolerance for the boost converter so I hooked it up to the boost converter.
I took a volt reading at the connection point and now the voltage dropped to about 0.2V. I have tried this with multiple panels and regardless of the no load voltage, it seems to drop to about 0.2V.
The boost converter also has a USB output and when I plug it in to my phone, nothing happens. I have confirmed the boost converter works because when I attach the dc inputs to a 1.5V alkaline, the system powers up. What do you guys think the issue is? Do I need to input a stable voltage/current?
