SUNYIMA 10pcs Mini Monocrystalline Solar Cells Solar System Kit 50mm X 50mm/1.96" X 1.96" 2V 160MA for DIY Charge Solar Panels

Works as advertised on my stem NSF project for my students. Thanks!

I soldered (easily) a pair of leads onto the panel, attached my voltmeter and headed into the sun. voltage was pushing 3 volts open circuit easily. I build little solar devices for my garden, and these panels keep the batteries charged even on cloudy days for all-night operation. Excellent for DIY repairs and hobbies.

Good panels. Good value

I tested all 10 solar cells and they were good. It was a perfect replacement part for my solar garden lights.

No way to test them, but giving 5 Stars anyway

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.

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.

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

Repaired my solar lantern

Thanks thanks

Pratique pour réaliser quelques lampes d'ambiance extérieures totalement autonomes. Associé à un accu, un ruban de led et un contrôleur de led.

1,2 V e 160mA più che sufficienti per ricaricare Ni-Cd da 1000mA e oltre per catene LED da giardino e altri usi. 100% soddisfatto.

Små men fina paneler.
