    Voltage Regulator and Solar Panel

    In addition - the spec sheet for the small solar panel states 330mA at 6v output. I'm guessing it needs to be angled right at the sun rather than the 45 degrees I did my testing on. Still not enough though.

    Voltage Regulator and Solar Panel

    Testing using the smaller panel - I attempted to charge my 2000mah LiPo battery and it was on the window sill all day in full NZ sun from dawn to dusk and was still not fully charged. I had to plug in the mains plug pack (which is 500mA) to finish it off. Not ideal. The original plan was for...

    Voltage Regulator and Solar Panel

    These photos show my larger 12v panel attached to the meter both with and without the voltage regulator attached. Please excuse the crudity of the regulator lead, the wires to the plug were far too short to make it any tidier.

    Voltage Regulator and Solar Panel

    I have attached images of my smaller Solar Panel attached to meter. This one is unregulated and gives off 6v. It connects to a LiPo battery charger designed for solar power input that then charges a 2000mA LiPo battery. This then plugs into my iPhone and charges that. This panel works...

    Voltage Regulator and Solar Panel

    Thank you for your reply, Under ambient light the solar panel only produces 0.03ma - I think this may be the problem, I need to test it in sunlight. Despite it reading over 12v prior to connection to regulator. Only data I could find on the panel is here...

    Voltage Regulator and Solar Panel

    I have a 12v solar panel that I need to step down to 5-6v I have a voltage regulator 7805CT which when I connect to a 6v battery pack outputs 5v without a problem. However when I connect the 12v solar panel to it the input voltage (output from panel) drops instantly to 2-3v and the...
