Newpowa180W(Watt) 10BB Solar Panel 12V Monocrystalline High Efficiency PV Module Off Grid for RV Trailer Camper Rooftop

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

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.

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 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 purchased this back in October. It sat for a couple months until the van conversion was ready for it. After installing it I noticed the solar charger was only reading .3-.5amps. I disconnected from the charger and read .7-.9amps from a multimeter. There customer service asked me to get into the junction box. Unfortunately the junction box isn’t the easiest thing to get into and I began to get a little frustrated.There customer service has been pretty responsive and considerate though. They are sending me another panel at the moment and have given me the option to send the other panel back in the box I receive. I’m hoping it functions much better🤞🏼Again I haven’t experienced the panel working but I plan to update this review when the new one comes in.

I bought these panels specifically to try to get close to the max power of 500 watts on my Bluetti EB150. In order to stay within the maximum open circuit voltage of 68 volts I found that many the Newpowa panels have an open circuit voltage of around 20 volts. I chose to go with the 180 watt panels and the voltage of 3 stayed below 60 volts open circuit. Each panel separately gave me 151 watts connected to my EB150. 2 panels in series gave 320 watts and 3 in series gave me 465 on one day and 475 watts on a slightly better sunny day. The EB240 has the same solar input specs in should do about the same. I uploaded a picture of the EB150 screen showing the input power with the 3 panels in series.

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.

I installed 4 ea Newpowa 180 watt panels on roof in series/parallel for 24vdc to a Victron 100/50 amp mppt. They charge two 300ah lithium batteries. Batteries are connected to 12vdc system and 4000 watt sinewave inverter. System works very well for last two years.
