The Honest Critique –
I have two solar panel charging systems, one on both of my boats. I use this solar panel on both. It is matched with a Uxcell Intelligent PWM 30A Solar Panel Charge Controller 12V-24V Battery Regulator PV2430 and it keeps my batteries constantly topped off. I do not turn the systems off at night. Both systems are twelve volt but both have multiple 12volt 1,000amp/hr batteries wired is parallel.

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.

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.

Mounted two of these on the roof of my travel trailer, a Blue Sky SB3000i Solar Boost MPPT Solar Charge Controller, a GIANDEL 3000W Heavy Duty Power Inverter, a Honeywell 525 CFM Indoor Outdoor Portable Evaporative Cooler, and 2 Optima Deep-Cycle batteries. Along with my “urine-diverting composting toilet” to save water, I am almost entirely self-contained: “dry camping in comfort”. Not beholden to anyone (RV park or government) and only need Honda generators on rare occasions. All bought at Amazon (they love me!)

I bought 4 – 170 watt panels from Newport and then added a fifth – 175 watt panel. They all work great. I have them running into a Tristan MPPT 60 amp charge controller. Keeps my battery bank fully charged on my Newmar Bay Star. The four panels did the job but added fifth so I wouldn’t have to tilt the panels. Good quality, work as advertised.

Panel in well built and has withstood higher winds with no problems. Overall output is net the %70 percent range at peak times that is expected from this class of solar panel(same or above several other common name brands). Bought as a test. Starts producing power with little light early in day and late evenings. Works well with partial shading and is only slightly larger then 100w panels. Planning to buy several more to add to the test system and see how they perform in serial connections. Only complaints are packaging. Had very slight cosmetic damage to frame due to flimsy box it is shipped in.

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.

We mounted four of these on our sailboat a few weeks ago. Because they are mounted flat, and there are numerous shade-producing elements, I was expecting perhaps 400 watts from the array – but we’re getting more like 550 watts, and the array produces usable power at very low sun angles (early and late in the day). I’m very impressed with their performance, along with our Victron MPPT controller.
