I have to put together a small solar system for a college project.
I have solar cells with an output of 3.65A and 0.6V. Now if I paralel two groups of two cells connected in series I will double the amps and volts. And the output power will be like 8W.
The question is, do a 1.2V panel really work? Can I charge a 12V battery? I mean the panel will be 8W and high amperage low voltage.
Do I need to have a minimum 12V panel to charge battery? This means I will have to put in series 20 cells to obtain 12V.
Are there high voltage low amperage solar cells so I don't need to put together so many cells?
