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 great as replacement in solar yard lights.

Easy to use. Good value. Better power output than expected. Great for little projects.

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

Good panels. Good value

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.

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

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.

No way to test them, but giving 5 Stars anyway
