    Build quality is good and it almost match the 3W/6V specification at ideal conditions. I have ordered 5pcs for some robotic project and they come well packaged in bubble wrap and quite fast. If you cut track on the back side you can re-solder the cell in different way to double the current sacrificing the voltage (see picture)

    items tested with a multimeter, putting out around 5.7 volts in cloudy overcast British weather, no doubts what so ever that they will perform even better in direct sunlight. should work well as part of self powered bird cam project. Note positive and negative not marked, but multimeter soon shows polarity.

    Good quality

    The panel comes bare, so you probably need to solder on cables yourself, but if you need one of these, you want to wire up more in series or parallel with a diode at the end. The quality is excellent, and consistent in all the 8 solarpanels I bought. Delivery was fast, surprisingly fast, considering it was sent from China to Norway. I think it took just over a week.

    I bought these cells twice for a total of 6 elements. They are very valuable monocrystalline cells, especially compared to similar, same dimension, policrystalline (145x145mm) banggood 12v 250mA cells. They could erogate 6~6.5V and up to ~400mA short-circuit current in full sun, so the real power is about 2~2.4W, but I really appreciate them anyway!

    панель пришла целой и за короткий срок. брал для самоделки. остался доволен. сделано хорошо.

    Received the panels quickly and they worked well. However, in order to trickle charge a 6V lead acid battery, you need about 6.75V. This panel only puts out that voltage when there is full sun directly on it. It doesn't generate enough voltage to charge with cloudy skies. If it doesn't keep the battery up, I'll have to add another panel. My application is charging the battery for an automatic fish feeder.

    The solar cell is of solid construction and quality. I wasn't able to get the full specified power out of it but I only tested in the afternoon, when the sun has not the maximum radiation intensity. Only negative point so far was a sticky film on the surface after removing the protective foil. I could remove it with cleaning benzine. (Thats minus one star)
