Qimoo 10Pcs Mini Solar Panels for Solar Power, 5V 60mA Mini Solar Panel Kit DIY Electric Toy Photovoltaic Cells Solar Epoxy Cell Charger Plastic Base Plate 3.15"*1.77"(80mm*45mm)

Good quality, voltage output is slightly higher than rated, works very well. I replaced a failing older solar panel on and exterior light and the new panel charges the battery to where the light stays on the entire night and into the morning.

I am in the process of building a charger with these solar panels. I did want to at least give my basic review so far. I connected these in parallel to keep the voltage around 5.5 volts and increase the output current. Even in moderate sunlight, they produce an honest 5.5 volts. In direct sunlight, the voltage goes up to almost 6 volts. In putting a load on the output, the 5 panels produce a little over 500mA with the voltage sagging just a little. I'm working on circuitry to maintaining a constant voltage and charge rate. I'll update review when I am further along with the project.

This is easily nearly double the side of what they have listed. I have a deadline that I now am not able to reach because people don’t know how to measure. SMH Just terrible

The solar cells seem a little roughly made. They have the appearance of being used, but I don't think these have been. They came with an adhesive protector on the cell surface and the connecting pads on the back are clean with no marks. But, the back itself looks roughly made like it didn't get a good clean coat of epoxy on it or something. The back layer is plenty thick enough though.They appear to be constructed of 4 cells in series. On one of mine, one of the cell wires was not solidly soldered to the pad, but that was an easy fix since I was soldering on lead wires anyway.In the late afternoon, around 4 PM in the winter, I measured 5.9 to 6.0 volts output. So at least in terms of voltage, they perform well. I don't have a way to measure milliamp output.

These came in a 5-pack (not 10 like the product description states), but they are well made and durable. They are mini solar panels that are great for solar powered projects. I do not expect them to be high-powered due to the size of them and the maximum being only 5 volts. They were packaged in a plastic bag but do have protective plastic on each side of each one, making them protected well enough even when together.
