They are great for yard ornament

I did not take my time when ordering these I made a mistake. My fault not theirs, but quality seems to be high and I will find a use for somewhere at some point.

Lo que esperaba, necesitaba levantar una mini bomba de agua de ardunio de 3-6 voltios y sirvió perfectamente, el único detalle es que en la superficie de las celdas tiene como unos plásticos con aire, pero es solo superficial, casi imperceptible y no afecta su función. Volvería a comprarlo

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

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.

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.

First, be aware that these are very low power. They are not going to provide a lot of power but are good for situations like trickle-charging trail cameras or LED string lights, etc… They are durable and easy to work with. I’ve not seen any discoloration or fogging of the solar panels so far.
