180W Mono Solar Panel

works great have 5 on rv for 925 wats of solar

I elected this size for two reasons. It covered the chicken coop roof well as well as provided me with 180W of energy.It was connected to a cheap solar controller as well as an AGM batter 12V 35amh. It should charge this battery in about 3 hrs. The panel came well packaged. Seem to be very good quality. Sealed with a glass on top. Made in Vietnam.It did not have the cord that attaches to the clip on leads to be able to attach to the solar controller. I found about a 9" ones for about $6 (otherwise, I would have to cut the male and female clips and expose the wire and I did not want to do that). I also bought the universal NewPowa roof attachment kit that worked well. You can buy a kit that has all these but it was a lot more than if you buy all of these separately.

I ordered ten 175W panels from Newpowa for a solar project at our summer House in Michigan. I had previously purchased two 25W panels from Newpowa and I was impressed by their quality which is why I chose Newpowa panels for my larger project.I received the panels but discovered that one of them was damaged and requested a replacement. Newpowa promptly offered either a refund or a replacement panel. They shipped the replacement via Fedex and I received it in 3 days I installed the 10 panels in two 5 panel arrays on the roof and they are producing 1000-1300 watts consistently. I couldn't be more pleased with the panels and the service provided by the seller.They make a great product at a competitive price. I would recommend Newpowa panels to anyone considering a solar project.

Shipping was pretty slow, but the unit arrived as expected. Like the other reviewer, this unit was placed on the roof of my Kia Sedona van and run down through a charge controller and out to a battery pack made up of two Nissan Leaf batteries wired up in series. The load on the charge controller powers 12 volt items and USB plugs for various phones, tablets.The solar panel's frame is solid and had holes already drilled into the frame. I placed washers on the top and bottom of a bolt that ran to an L-bar cut about 12 inches in each of the screw hole sections. Into those I ran u bolts around the bars in my roof rack. And just for extra safety I added zip ties in case one of the bolts worked out.The connectors on the end fit perfectly in my standard MC4 connectors. The wires were thick. I have not seen more than 110 watts out of the panel, but normally my batteries are recharged before the mid day's sun. And my panels are flat on the roof. You can literally hang off the frame edge and it does not flex.

I wish I had done my research before going the harbor freight route, but it was an affordable entry into solar. These panels are way more efficient. I will buy this product again.

Good panel for RV. Added this to my existing ones.

These panels do not have the power they are advertised at. I have a MPPT charger and excellent cables. I was only able to pull about 60-70 watts in direct sunlight (~2-3 amps). I am experienced with solar panels and these panels seem more like 100 watt panels. However, they do work and the frames and junction boxes are well built so I am giving them 3 stars. Perhaps in perfect conditions and latitude they might get higher power, but under the conditions I am using them they should easily be breaking 100 watts.

If you have an ac180 you'll know it's hard to get to the maximum 500 watts with solar panels without going over the 60v 10a limit. I previously bought 2 pv200 bluetti brand panels, a third would go over the 60v limit. They only gave me 250 watts on a perfect day.Now on to these newpowa panels. I was able to get 3 because the voc is 19.84. Wired them up in series and voila. These are the only panels that let you get close to, or in my case actually hit my 500 watt goal! I'm so happy.As for the shipping I was worried that they would be damaged on route. Many other companies use very little to protect their panels. Well newpowa does an amazing job with protection almost too good. It got a little annoying removing all that protective wrapping and cardboard. Anyways buy these panels they are great... so far. I'll update if my opinion changes for the worse.
