ECO-WORTHY Solar Panel 25W 18V Monocrystalline Waterproof Panel for Charging 12V Battery of RV Boat Trailer ATV Car or Powering 12V Light, Charing 12V Battery Pack and Other Off-Grid Applications

It works so worth it for me8

This 10 watt solar panel is great for small powered projects around the house. If you require 10W or less, 1/2A, 12V power to something outside and there is no electricity near, you can always power it with an added solar controller & 10Ah,12V battery.

Have purchased several over past 2 years. So far good results. I use them on gate operators. Works as they should. Quality product

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.

This little solar panel is amazing I use 2 of them with my 100 watts solar panel to charge my ecoflow river 2 and they output the full 10 watts each which most solar panels output less then they say they do. The price is worth the purchase for sure.

We use these for science lab activities and they work very well!

The media could not be loaded. It’s great. Voltmeter shows 22V open circuit as advertised. Actual performance is ~15 Watts up to 20 watts of power in full sun.The glass is durable and the junction box is waterproof. The corner edges are sharp, I dulled the corners and wrapped the corners in electrical tape for safety.I use this for 3.7V lithium cells, I recommend EcoWorthy pv modules for battery chargeing.I will possibly be buying more

Works great
