ACOPOWER 200 watt Solar Panels,High Efficiency Black PV Module Power 200W Mono RV Solar Panel for 12 Volt System,RV Marine Boat Cabin and Other Off Grid System

Good 200 watt panel!, The best thing it's made in the USA not China !!! I'm going to buy more !!

The media could not be loaded.  The unit I got seemed like it was a return because the package was double taped. It also appears that it was returned because the silicone applied between the panel and the frame was done poorly. The long sides of the aluminum pulled away from the frame. I used window weld to secure the glass panel back to the frame. I also created gusset and crossbars out of aluminum to rivet to the backside of it for when I mounted it in my roof rack for a mobile application. It was below average sturdy before but it is very sturdy now.I would have returned it to get a different unit without the problems but none were available. I like the color of this unit, the size of this unit, and the fact that it works fine. I’ve never received the full wattage that it advertises but I understand this is normal for every solar panel and that they only get the maximum advertise wattage when the stars align and the circumstances are just right.

Unit was packaged very well, arrived in perfect condition, and mounted easily on my frame. My only gripe is that even under very nearly ideal conditions (Sun at zenith, mid summer day in deep south with panel pointed exactly face-on to the Sun) the panel has only produced 160W at best, and generally hovers at or a bit below 150W. I had been hoping for a at least consistent 175W to 180W or so under real-world conditions at peak charging time. Although I have the panel mounted so that it gets airflow, it's still possible the high summer temps are impacting efficiency. Temps have been in the low to mid 90s during these measurements. Nevertheless, I'm please with the unit and have ordered another to add to my system.

I bought the panel because it was $40 cheaper than their competitors they look identical and I happen to own 4 of the other brand. Same output ratings on either but the holes for the brackets are off by slightly over 1 inch. I now run 5 200 watt panels and get about a easy 40-42 amp charge rate now for my 300 amps worth of batteries, I added the 5th one to make up for the loss of the Sunlight in the winter. Over all with my 80 feet of wire I still get around 8 amps per panel at the MPPT.

Put two of these on our travel trailer. They work well. However, not as much output as I would expect from 200 watt panels. No panel ever puts out the tested amount but these only did about 150 each mounted as shown. This was in bright June sun in Utah. It would have been better if they were facing directly at the sun but still not close to 200 to claim that rating.

mounted on top of my carpet cleaning van to power my rockpals power station and refrigerator and keep my dewalt batteries charged.. wanted to make use of them when i wasnt camping.. panels gets 9w power in the shade and 120w in direct sunlight (85 degrees out) pros: value for money power out put is more than expected, very easy to install. cons: one panel frame was slightly bent at corner, power not likely as much as advertised, didnt come wiyh mounting hardware

I purchased two panels and tested both. I was concerned with one of the reviews here that the panels were not 200 watt panels. But after testing I no longer have concerns, one panel was right on the money was producing 200.44 watts, the other ended up producing a little more at 209.14 watts. Both were tested in the same spot, same angle within 5 mins apart during the suns peak in 76f.Update: After installing the panels I'm getting a consistent combined 230-250 watts, at the suns peak the max I've been able to get was around 340 watts which lasted about 30mins or so. I have about close to 2000 miles with them and they have been holding up pretty well. No complaints.

Seems to be of good quality. Charged up my deep cycle battery quickly using a decent MPTT controller designed for 12vDC systems and my battery type. Panel is a good size for my vintage van conversion and I like that the panel has pre-drilled mounting holes on both sides of the frame for easy, secure mounting. You can remove the back plate to reveal the soldered connection inside. If careful, you can replace the leads. The positive is on the right and negative is on the left when looking at the junction box on the back of the panel. Double check with a vote meter before connecting to your charge controller. Replacing the two diodes is possible on this panel if that's ever needed.
