I got these on a whim after thinking about making my own solar USB chargers. After a bit of research, I settled on these and set to it. After wiring in parallel, and connecting diodes to prevent current shading, three panels reliably gets me ≈400ma-420ma. Yes, that’s less than the USB standard, but as proof-of-concept I was happy with these results. As seen in the pictures, I used six of the ten panels building two working units. The remaining four will be used together for a higher output of ≈560ma, which is slightly better than the USB standard. Not PD, I know…but as a beginner’s project I’m satisfied. Recommended.

These are a good size and well made. They come at a good value saving you money. They perform their job well once installed.

I found nothing to dislike, Worked perfectly in my project.

I’ve fallen a little behind on projects that I have planned, so I’ve only done a few experiments with these solar panels thus far. They are very durable with a good thickness, so I believe that they will work out very well for what I have planned. They look like they will work very well when exposed to the elements, as long as I have good seals to protect the electronics. My plan is to use these on some solar racers, so once I have something, I’ll try to remember to come back here and post an update.
I also have plans for a charging system by day, fun lighting at night, but that is a much longer term project. These panels should work great for both projects. The waterproof coating on the surface looks like it will hold up for many years. One of those projects is for a home street number board that I will design with 3D prints. Sudo black (clear with dark background) on white during the day, lighted at night.
That makes be think about a solar powered mailbox as well. More projects…

UNBIASED
Amazon Vine reviewers are not paid for reviews, be it positive or negative. I will never recommend a product I would not buy myself.
PERFORMANCE
I think most would agree we need to do more that watch a screen, especially as a kiddo. These little solar cells are so much fun to play with for all. It is fun to problem solve, it keeps our minds active. These cells give the feeling of discovery and the satisfaction of capturing sunlight and making electricity. A pack of these cells, tiny electric motors, wire leds etc and let them go at it. I owe so much to my cigar box of such things and it took me farther than I could have ever imagine. Solar cells can teach so much. They are a byproduct of the space race and after all this time it just might have the capability to get the kids to drop the game controller longer than 5 minutes. Have some fun and be a kid again yourself as well.
The cells are of high quality with good large areas to solder. I think some ideas, just a little manual or onsite sources on ways to use the cells will help with project ideas
VALUE
Performance Vs Cost Equals Value. Some reviews are harder than others but this one is hard to deny, both quality and price are very good.
BUY OR PASS
BUY, BUY, BUY – Without hesitation for the DIYer or future scientist.

I am new to the solar energy field. been looking for affordable ways to test and learn about solar energy. These panels had some good reviews so I decided to try them out.
Highlight:
– Design: Doesn’t seem to reflect light at all makes me feel like they adsorb light well.
– Durability: These panels seem to be able to bend or be flexible more then traditional panels or mono-crystalline cells. Which should suggest they are more durable,they should not easily not crack, and should be reliable.
Note:
– Output the Voltages and amperage will vary a bit between panels as it seems on most Budget panels. From the panels I got it I can see a around 10% difference of what they pull, But overall they still seem measure in around the manufacture spec output.
Overall I will give them 5 stars they seem to be decent panels even with there being room for improvement, and they make great panels for hobbyist or people looking for something to power or recharge small electronics.

these have been great for making diy smart home outdoor devices with out the use of single use batteries or drilling holes in to my home.

Haven’t done much with these beyond attaching a set of electrical wires and testing the solar power with an LED bulb. These are small and won’t provide too much charging power as single units, but I believe you can daisy chain them together to make them work in unison. Once I figure out the proper configuration, I plan to make a small solar charging table for my deck, with a USB charging port or two for phones, power banks and other devices. These are rigid, weighty panels, not flexible and light. Keep that in mind if you want to use them to power small cars and other things that move. Other than that, your imagination is the limit! These are great for teaching kids about solar energy and letting them experiment.
