So far I only looked at the first one I pulled out of the box. I soldered leads on it and took it outside for some measurements in the hot Florida sun. 6.6V @ 66 mA in South Florida Summer mid-afternoon sun. This exceeds the advertised 6V 50mA, which is probably what you’d get further away from the equator.

Tutto nelle previsioni. Come desideravo.

Die Module kommen in einer kleinen Pappschachtel. Zum Schutz vor Transportschäden ist auf der Kollektoren-Seite eine Folie aufgebracht.
Die Lötpunkte auf der Rückseite sind sehr großzügig dimensioniert und auch die Beschriftung ist eindeutig.
In einem hellen Zimmer konnte ich ca 2.6 bis 3.5V messen, am Fenster 5V und in der Sonne bis zu 6.2V – jeweils ohne Verbraucher.

I’d say they’re worth every dollar, and they don’t cost many of those.
The quality and consistency is a bit iffy. You can tell just by looking at some of them that the PCB/Traces underneath are varying amounts of crooked. Doesn’t seem to harm their functionality any.
One of them, the solder pad came loose. Upon closer inspection, the trace itself detached from the PCB. I could have sunk too much heat in to it, or it could be crappy traces. Hard to say. Not a huge deal though. I can always solder straight to the contacts on the outside edges and recover that one.
I’m using them to keep an esp32 device charged up and after a week’s worth of measurements, I believe it’ll do that just fine.
It seems to meet/exceed its specifications. I’ve measured as high as 65ma out of it so far in peaks, 20ma when a cloud rolls by but its still an overall sunny day. Less as the days get worse, of course. Without perfect placement I’d judge its average around 40ma or so.
Minus 1 star mostly from the minor nitpicks and a general “nothing is perfect” rating. But I’d give it a 10/10 just based on “would I buy this again for a project it’s specifications meet.”

Used these to make a solar hat.

Low current requires these to be run in series and parallel

ok

Other then a few factory hot drips and scrapes… performs well.

Arrived on time, and all read at correct voltage in direct sunlight.

Ce lot est composé de 10 mini panneaux solaire de 8cm sur 4.5cm. Ils sont livrés bien emballés dans une boite avec un plastique de protection sur la face solaire.
Les points de soudures sont bien accessibles pour y fixer les câbles. Ils sont donnés pour 6v et 50mA, et j’ai mesuré 6.2V pour 187mA, surprenant cette intensité 3 fois supérieur. En branchant 2 panneaux la tension monte à 464mA. Parfait pour les montages DIY pour alimenter de petit appareil ou recharger des batteries.
