## Description

desertcart.com : Sunnytech 1pc 3W 12V 250ma Mini Small Solar Panel Module DIY Polysilicon Solar Epoxy Cell Charger B047 : Patio, Lawn & Garden

Review: Perfect - Works perfect to power a 12v fan for the black waste vent on my camper during the hot summer months.
Review: Works, but not getting full output yet - No issues so far. I'm using this with a charging circuit for a 18650 battery for a data collecting application. It's doing the job, but even in full Florida sun, I'm not hitting the advertised output. There could be a host of reasons for this (including operator error). I've picked up cheaper panels from eBay with similar output, but was hoping that the slight premium meant higher output.

## Questions & Answers

**Q: WHich character is positive and which is negative?**
A: If you are looking at the back of the panel, just above "Solar Panel", positive is the one on the left.  (I used Google Translate App to figure that out. The first character looks like part of a plus sign.)

**Q: Does the panel have outlets of some kind or is it to be wired?**
A: Mine came with no wires. On the back of the panel are two copper pads to solder the output wires to. On mine the positive was on the right, negative on the left.

**Q: Could it work ,with a small 12v battery**
A: The solar panel is 12 volts... You can use it with a battery charger... You would have to check the specs, to see if you can charge your battery... Does this answer your question?

**Q: Can i use this for a trail cam that has 8 aa batteries**
A: 8 aa batteries equals 12 volts, it should maintain the batteries as the 12 volt panels that are sold for trail cameras

### ⭐⭐⭐⭐⭐ Perfect
*by B***N on August 18, 2018*

Works perfect to power a 12v fan for the black waste vent on my camper during the hot summer months.

### ⭐⭐⭐⭐ Works, but not getting full output yet
*by K***E on June 16, 2020*

No issues so far. I'm using this with a charging circuit for a 18650 battery for a data collecting application. It's doing the job, but even in full Florida sun, I'm not hitting the advertised output. There could be a host of reasons for this (including operator error).

### ⭐⭐⭐⭐⭐ Great for what they are
*by M***S on May 27, 2022*

These are DIRT cheap 3W panels. I've gotten a handful of themn over the last year or so. Typically I hook up two in parallel to a USB buck converter for making a little phone/powerbank charger, and they work great for that. One panel is more than enough to power little microcontroller applications/low energy demand stuff. Lots of fun DIY projects to be had with this, I'm hoping Sunnytech makes more of this model available. (I just bought another 7, but there's only a few left in stock as of this writing). If you're reading this though, Sunnytech, you'd make me reeeeal happy if you made a single panel that was 12V 6W. Would definitely make 3D printed enclosures easier. :P
