Question 4: How to judge the Solar Cell?

Answer:

Check the Appearance color, good solar cell the color almost the same.

second check the wire if it has some broken, third using device to test the power of the solar.

Question 5: When I buy your products, How to ship?

Answer:

If you buy a few cartons, DHL/FedEx/TNT/EMS will be better, if you buy container, shipped by sea
