Ich verwende die Zellen für kleinere Projekte. Sind gut, man sollte sich aber nicht zuviel erwarten.

Li ho utilizzati per ripristinare i miei vecchi lampioncini del giardino….sono ben rifiniti con bordi arrotondati belli veramente facili da montare e resistenti molto contento del risultato

Works great. A little pricey but seem to be worth it as they’ve held up well so far.

Leider stimmen hier die technischen Angaben nicht. Der maximale Strom liegt bei ca. 60-80mA, aber ganz sicher KEINE 160mA. Das mag für die LEDs im Garten irrelevant sein, aber wenn man ein technisch komplexeres Projekt plant, dann sollte man sich auch auf die Angaben vom Hersteller verlassen können.

2.3v in full sunlight, these are probably seconds because the encapsulated grid is shifted a little in each, but they work just fine. Very usable.

Not much to say but they work and I think they were the same brand that I was replacing, it was definitely cheaper to replace the solar panels then to buy new lights, and I love fixing things then just throwing out and bying new.

I used these to replace 75 x 75mm cells in old vinyl fence post lights. Measured in full sun, central Florida, 3:30 PM, mid May, open circuit voltage 2.43v, closed circuit current 190ma. The 75 x 75mm cells produced a little less current and voltage, but to be fair, they were several years old. I designed and printed new housings that angle the cells at 25 degrees (best angle for my latitude) vs. the old cells which were horizontal. It will be interesting to see what condition they are in a year from now in the hot Florida sun.
Edit: One year later and all the cells are still working like new. I would buy again if I needed more of these.

I received 10pcs of Sunyima 50×50 mm Monocrystalline 160 ma. Two of them has broken conductor line. I do test under full sun, current is reduced by more than 50% (Fluke 87 read 76ma) Seller please check your product before send it to buyer. Thanks!

I’m working on an automatic watering system. I’ll use 2 panels to keep a 18650 battery charged. I’m using a boost converter to drive the latching solenoid valve. Of course a CPU to control everything.
The output power was not quite what was advertised. Full sun in California, 100mA. Still, not bad at all. Nice solder pads on the bottom to work with. Happy with the purchase.

The epoxy coating turned yellow and opaque in less than 6 months. Why would they make solar panels that don’t last in the sun? I won’t buy this brand ever again.

The best MA output in direct sunlight was 114.
