Let this solar panel bask in the sun and it will generate DC power
It can directly drive a small DC fan or other DC equipment whose voltage requirements are not very stable
/p>< p> If you connect an external battery to charge the battery, you can generate electricity and charge it into the battery during the day, and use it to turn on lights and charge mobile phones at night.
If you add an inverter, you can drive household appliances.
I've said a lot, but I still don't know what the V is on your board? What power ?
If you know, I can offer you a more reasonable method.
