  • Perfect!
Size: 100W Single Panel Color: 0 Ah
I have over 200 panels, and these I'd give an A+.

  • Great output and nice size
Size: 100W Single Panel Color: 0 Ah
I bought two Acopower 12 volt, 100 watt monocrystalline panels to charge my Ecoflow power stations. I built an adjustable rack so I could easily move them and orientate them correctly to the sun. I connected the two panels in series and expected the typical lower output per panel like many of them but was pleasantly surprised to see between 195 and 207 watts. This was in perfect sunny conditions. Their size and weight is excellent and makes them easier to handle. They look nice and seem well built. I'll update if they start having issues, but so far, I'm very pleased after two months of use. I live in hurricane alley so I am planning to buy two more to double my emergency power. ... show more

  • 5 stars Love these panels and will not buy any other.
Size: 100W Single Panel Color: 0 Ah
These are great. Had for one year now and no problem. Output power is great and keeps my battery bank charged. I will purchase no other panel except for these. Absolutely great price. Don't fall for other manufacturers panels. All powers are one of the best in my opinion.

  • You can self install. Just be thoughtful and deliberate
Size: 400W MPPT40A Color: 0 Ah
Just finished install of 400 w mono crystaline panel kit on my 24 ft travel trailer.. Order arrived a week ahead of schedule! Packaging of panels and accessories was very secure. All listed parts were included. For a 4 panel system you will need to order extra MC4 connectors for the long cable runs. I bought a kit that also included the crimper. GET THE CRIMPER and DO THESE CORRECTLY! (The crimp goes on the stripped bare wire not over the plactic wire insulation!) The supplied 10 ga cable was adequate but I needed just a bit more of the 8 gauge wire from controller to battery. ( Routing this system for a travel trailer is more challenging than on 5th wheel or Motor home) You will need to supply tape mastic and sealant for installing panel mounting brackets and roof gland. I also added a 30 AMP circuit breaker in the postive line before the controller. Also a 40 amp circuit breaker on positive line between the controller and battery. I installed the controller in the front bedroom and ran cable to battery through a hollow compartment below, drilled throught the floor and tied up the cable to the frame 'till it reached the battery. I used plastic surface mount conduit to cover the wire from the ceiling to the controller. Also used a plastic box to hide the 30 amp circuit breaker. The 40 amp breaker is hidden in my hollow compartment below. I also added a 10 amp blade fuse in an inline holder to the positive line of each panel. ( you might see the red wire and fuse holders in my roof wire runs. After I had it all working I put the roof cable in plastic split loom type tubing for neatness and extra protection. Then fastened it all with cable ties to available brackets and points. When I plugged it all in and turned it on, Presto! It Worked! Making good connections is important. I ended up re-making most of my MC4 conections for my 10 amp fuses and long wire runs after discovering I had done thm incorrectly! Same with connections to controller. The wire is stiff. Only finished today. We will give it a 6 day trial run next week. We are in cloudy Oregon so I do't expect big amperage output till the sun comes out. ... show more

  • Reliable Power
Size: 100W Single Panel Color: 0 Ah
I've been using it to charge a 12V 20AH LiFeO4 battery to power a refrigerated cooler. The setup keeps the cooler running night and day. I've had it for about a year and it knocked it around a bit, still works great

  • 300 watts to go! Mounting on the roof of a camper van.
Size: 100W Single Panel Color: 0 Ah
I’ve been searching for a solar panel solution for the roof rack on my DIY minivan camper. I have battery power station running a 12v fridge freezer, some fans, a small coffee pot, small microwave, a blender and a few other comfort items. So I needed more than the typical 100 watt panel. I looked at 300+ watt panels made for houses, but they weren’t the right size for my application. I finally purchased 3 of the 100 watt black-frame panels from ACO Power. They had good reviews and they look better than any other panels out there. The black frames are very sleek. I got 160+ watts on first test, but the sun was hiding and the angle wasn’t ideal. In full sun directly overhead I was able to get 275+ watts which awesome. Having tested the panels, it was time to mount them. I bolted the panels together (side by side), then mounted a small metal conduit pole to serve as a ‘hinge’ so I can tilt it as needed. I have mounted steel eyebolts on my roof rack that the ends of the poles will slide into. That’s as far as I’ve gotten. I’ll post an update after I finish mounting and do some highway road-tests. But I’m happy with the panels so far. They look great, they don’t weigh too much and they produce plenty of watts. ... show more
