   Working great, will report back next season on its condition after leaving it outdoor.
   Was able to get 1.2A of charge current into a 18650 at Vmpp 17.5V at the input.

   When shaded, it dropped to 100-120mA, still very usable.

   I have used this panel for about a year, has stood up to the elements well. Nice size and easy to handle, installation was easy.

   Like any solar panel, I was expecting to see maybe 75% of advertised wattage in absolute perfect conditions … especially considering these are the less efficient Polycrystalline panels. The construction feels sturdy and I set them out on my truck bed today over lunch just to see what power they’d produce. This was mid-day sun but also in the middle of the winter. I also didn’t have them mounted perfectly to get all the sun, just laid them out on my trunk and I was getting ~37 watts from each. (21.92V @ 1.677A) I didn’t have my charge controller on-hand but that would translate to over 3A @ 12v! Combined these will out charge my plugin! Perfect addition to my boat to keep batteries topped off. Very pleased.

   I had an old 50W solar panel from the mid-80’s on top of the RV I just bought and it had degraded to the point of just putting out less than 5W in full sunlight. I replaced it with this panel, ran new wires through a new controller, and used 3M 4950 VHB tape with Renogy mounting brackets to mount in a better place on the roof. This panel already has pre-drilled mounting holes, so I just had to install the brackets and stick it to the roof. (NOTE – You also have to install the connector of your choice on – I used the MC4 connectors that come with the panel). In full sunlight this 30W panel puts out a consistent 25W, and will keep my house battery fully charged. The only reason for 4 stars is the panel drops to 3W in the tiniest bit of shade… (IE – shade one corner of the panel).

   The solar panel’s performance metrics consistently match the manufacturer’s specifications, delivering reliable power output even under varying weather conditions. Unlike several other models I’ve tested that fell short of their advertised capabilities, this unit efficiently converts sunlight to electricity, making it a trustworthy choice for residential and RV solar installations. The real-world energy generation aligns perfectly with the rated capacity, demonstrating exceptional value for the investment.

   I installed on my battery powered gate opener. This 35 watt unit replaced the original 10 watt solar panel. I had to splice panel wires into battery wires. I was able to use the same aluminum installation bracket. I purchased a new battery at same time as new solar panel. It’s been 4 months and working perfect. Update: it’s been 8 months since installation and still no problems. Gate opens every time and no depleted battery like before with the original 10 watt panel. The weather is cloudy and rainy most of the time and the original 10 watt panel was not cutting it. I’m very happy with this 35 watt panel. Highly recommend!

    Puts out just about the current specified. Looks well made. Should work for my solar fence-charger project just fine.

    My order came very fast and we installed it on our sailboat to charge the battery. Amazingly it was easy to install and it started to charge right away.

    This 10W panel does indeed produce 10 Watts in full sun.
    Produces about 200mA in weak morning sun.

    Wires are a bit short. No mounting bracket is included.

    There is a blocking diode installed inside the small black cover.

    Works well with my small charge controller.

    Good value at $18.
