Good price. Fulfills.

Nice little battery charging pad. Works well. I love the pre-installed Anderson Power Pole connectors. Just had to change the orientation for my setup.

Pros
  • Permanent test results
Cons

Solar and wind energy

After a few months, the panel stopped producing. Contact their support team. They asked for photos confirming that the panel was not outputting any voltage. Sent some photos. Now I have to give it back to them so they can make sure it's dead and then they send me a replacement.

Pros
  • Not long enough for a beautiful package
Cons
  • There are nuances

Odor OK using solar and wind power

Seems to meet performance specification. Durable aluminum frame. The junction box is not completely waterproof. I installed a plastic screen in the back of the open frame above to protect the junction box from rain and water. I also drilled 2 drainage holes in the bottom of the frame to allow any rain that collects there to drain. Be careful not to hit the glass pane with the drill! Otherwise I like it and will buy it more often. Mounts it on an old DISH antenna mount so it's very easy to…

Pros
  • Great design
Cons
  • Cable is shorter than other options

Decent quality panel for 15 watts

They were physically small for a 20 watt solar panel so I bothered to check them out. They put out about 1/3 less power than other 20 watt single crystal panels I have. They really should be sold as 15W solar panels given the performance they have. Now I don't have a standard Sun outlet to test with, so they may actually match the advertised rating, but they're a bit smaller than any competitor I've bought before. I like power pole connectors. They came from. I wear that anyway. They showed the

Pros
  • Everything is fine!
Cons
  • Minor issues

Overall Satisfaction Achieved

To be honest the best I've seen on a clear October day in 2021 was 25 volts at 5.5 amps. I'll refine this result by saying that the panels were flat and not tilted towards the sun. I suspect that if I tilted them I could see upwards of 8-9 amps, maybe the full 10 amps this panel is rated for. The panel weighs 35 pounds and measures approximately 3 feet by 4.5 feet. It's big and a person of average strength shouldn't have a problem with it. I bought it thinking it was the best price per watt and
