Does not work (even exchange did not help).

Bought for a school project, unfortunately does not work. Worked with Revain, got a replacement that didn't work either. We have several other designs from other sellers that work great.

Pros
  • Solar panels
Cons
  • I will add later

Didn't come with attached cables.

I soldered the wires and the contact strip came loose. I didn't re-solder the contacts to the tape and it seems to be holding, but it would be much better if it came with the wires attached. On the positive side, the panel met or exceeded the advertised specifications.

Pros
  • Solar and wind power
Cons
  • High price

This is really a great product. Well made and very handsome

This is a really great product. Well made and very handsome. The output matched my meter. I had to solder two wires to the back, which turned out to be easy. There was a good set of copper traces on the back for soldering, similar to soldering circuit boards. I cannot praise this product and price enough and will definitely buy again! I also received a very pleasant letter from the seller and a free rectifier at the output. The only advice I would give is to pay close attention to the position…

Pros
  • Generators and Portable Power Supplies
Cons
  • Secret
