Here we have strong sun all year so it could work fine!
Have you tried any solar panel set up?
I dont really know much about it, thats why im looking for information from peopme
Yes.
I have one very small system that runs a few LED lights in a shed, which just uses a lead acid car battery and a cheap PWM charge controller, so I can also charge anything that uses a USB cable. I think the PV panel is just 25W, but it is fine for trickle charging the battery. I also have a small inverter with it to charge a laptop.
It is not very portable though.
In this case the flash flish works as inversor and battery at the same time, i seem it really funtionable combined with a solar panel
