With attached wires and the stands it is easy and very quick to set up...
Go to a sunny area, without obstacles to block the sun.
Unfold the panels. Face the sun and it will start producing a power output.
Adjust the solar panel to get maximum sunlight during the whole day for most power output. For proper direction use the kickstands.
Read the safety instructions before putting the 70 watt foldable solar panel kit into operation.
See that battery clip connection is done properly. This is to avoid any short circuits.
Remember obstacles that cover the surface of the 70 watt solar panel kit reduce output.
Dust and dirt can some times cover the surface of solar
panels. Remove it, it can decrease efficiency.
Now you can clean using a soft brush. Remove the remaining dust and dirt with a damp cloth.
It is good to have a USB charge port, but it will only work when you connect to a battery.
Some people suggest Acopower to change the LED color from blue to red. Seeing the lights will be so much easier then, no matter how bright it is outside.
