Hi,
I got a 30 watt solar panel that I measured (not in the full sun) that puts out over 20 volts. I have not measured the output in direct sun but I imagine it is around 20 volts still.
My ultimate goal is to charge a bunch of rechargeable D batteries using this 30 watt panel. I found on Amazon a 12v device that charges two pairs of D batteries and I was thinking of getting a few of those devices and hooking them into my 30w panel.
What efficient solution can I use to make the voltage coming out of the panel be 12v so that I can power the battery chargers?
Is there a better method than using the battery chargers to use my 30 watt panel to charge a bunch of batteries?
Any advice would be greatly appreciated!
Thanks
