Eco-worthy 10w Solar Panel 10 Watt 12 Volt Pv Solar Module,solar Cell Panel, New

Use this to change a gate opener battery and it does great. I have used it for several years and it keeps the battery charged and ready to go all year even in cold weather.

I would definitely recommend.I bought two of these to put on the light pole for my solar street light. The integrated panel of the street light is only putting 5W (not these panels) into the batteries which is not enough to charge & keep charged a 25Ah battery.When they came in, I immediately grabbed my Klein mm720 multi-meter & headed outside. It was a perfect day for solar panels. I propped each panel up at 45deg & pointed directly at the sun. Both panels showed about 22.1V to 22.2V @ 0.57A to 0.59A, for about 12.5W to 13W output.Build quality seems great, power cable is fairly short, just over 3ft, but enough there to add whatever length of wire you need, and is 18ga.So refreshing to find a product listed with real spec's!!!!CON's: Does not come with any mounting hardware.

I had one of these before, but the one that came with a charge controller. I decided to buy just the panel alone to wire in parallel and use to charge/maintain two 12v sealed batteries of 9 AH and 20 AH respectively. I initially connected them to a Schneider c40 and got 19+v from the PV panels, but the C40 wasn't working so it didn't charge the batteries - I also wanted to test the C40 since I suspected it wasn't working. I connected the panels to another charge controller but it only registers in the 12.5v range for the panels but the days have been somewhat cloudy. I used to use the charge controller that came with the other panel, but the space between slots for panel, batteries and load is very narrow and what with moving it up and down the wires came a bit loose and adjacent ones touched and sparked! Have ordered another charge controller and will connect and see what voltage I get and how quickly it charges the batteries to maximum. Panels seem well made, are fairly light, not sure how water proof the connection box at the back is though. The hole in the box for the wires can hold speaker type wire, doubt it could take anything of a thicker gauge, even the strain relief has a very narrow diameter space and short screws.The back of the panel has 4 holes in the frame for attachment to roof or support. I bought some brackets but not sure if I'll use them yet.I'm currently resting them on an old shoe rack with wheels so that I can easily move it into and out of the house to get sun. Am toying with using the brackets I bought to install on roof but I like the idea of being able to move the panels around so I might not.UPDATE Oct 2018I mounted them on the edge of the roof and have had them connected to one of the inexpensive blue fronted PWM 20A charge controllers sold on Amazon. I put in a fuse from the wire on the roof to the charge controller as well. I run two DC bulbs from the charge controller, I think I used two 7w ones and used the timer on the controller to turn them on and off after about 6 hours. I also hooked up a mini voltmeter display to the batteries and the 2 panels keep the batteries fully charged with the light load it's running. They've been through some very heavy rain and seem to be holding up okay.

I combine this with a Schottky diode and a 20 volt Black and Decker Lithium battery.It powers my small QRP amateur radio in full sun and you can receive, without a battery connected or charge the battery simultaneously. The panel fits well on a bicycle where you may need portable power. If you use any oneof the Black and Decker tools, it could well come in handy. Sturdy and good quality, it has survived dropping. rain and direct sun producing 22 volts. peak You can reposition to gain maximum sun. The output of the unit is normal for a panel and you should always purchase a panel twice the power you need. Or go 4 times if you don't get desert sun! The ratings on panels are lab ratings and to learn more about this Google the topic. It's a good panel and does well for me.

I use this panel to power a "12V-24V DC Dry-run Protection Brushless Submersible Water Pump, 410GPH, for Solar Fountain, Fish Pond, and Aquarium" and it works great! I've had this panel for over a year and it has performed well. Obviously direct and clear sunlight works best.
