SEC 120 Watt 12 Volt Poly Kit, High Efficiency Solar Panel, Charge Controller and 15ft mc4 Cable Ideal for RV Marine Boat Off Grid

This was my second try at getting these panels. The first set arrived with the panels shattered. They were not boxed well and were easily damaged in shipping. The box showed obvious damage. The box for the replacement set looked ok and the voltage measured good. But, on closer inspection I fount that the caulking job used to bed the panels in their aluminum frame was very sloppy. Although this has no effect on the panel operation it is poor workmanship. The aluminum frames had multiple dents which looked like someone had taken a ball peen hammer an smacked them - hard. Some of the dents are about 1/4” deep. Again, the box showed no damage so I can only assume the dents happened prior to boxing and the panels were shipped to me damaged. I chose to keep the panels since I don’t have time to wait on another set and they do function. I don’t recommend buying these panels. Pay a little more and get panels that are assembled and boxed properly from undamaged materials.

I don't have a lot of experience with solar panels so all I can do is tell you what I saw as far as a comparison with some similar panels of friends. This panel seems to put out less wattage then my friends 150w panel. Not by much, and I think he paid more then me also.Packaging was sub par although my panel wasn't damages but there were spots on the box without padding where I could tell is was close to damage.So far I've had it about 5 months and it seems to be holding up though. Only thing that I really didn't like was the mounting holes, although I think this is similar on most panels. They really need to make a better way to attach these things to rv roofs.

Strong durable engineering sets this apart from other panels of similar price...cable length is acceptable.

Panel seemed to have good output. Quality control is lacking, cells were not positioned in frame evenly ( not sure if this lack of quality control will effect longevity). Panels were poorly packaged and damaged. I had to send them back.

Very easy to install. I install it in a class A mobile home with no issues. They came in as scheduled with no issues. The price was right. Strong material with excellent construction.

My husband bought this panel (120W) for his overlanding rig and installed it on the roof. With a clean panel at high altitude and the sun directly overhead, the *highest* output our Victron charge controller has recorded is 68W. So this panels is rated for 120W but is about 55% efficient.

Seems well made, fairly lightweight, mounted on my a-frame pop up. Don't like those MC4 connectors but an adapter at the ends of them convert it to the much easier to handle SAE connectors from there on out.

These panels put out 160 watts and are the same size as my original 85 watt panels. They charge in dusk hours where my old ones had to have full sun. I would recommend them to anybody that needs to go off grid or to go camping.
