Newpowa Solar Panel Mounting Z Bracket with Nuts and Bolts Mini Version Supporting for RV, Boat, Wall, Off Grid Roof Installation A Sets of 4 Units Sliver Aluminum

I have used these since 2016.I use them for solar generator, and for yard lights. They work great, I got me some more.Never had any problems. They are sturdy, and quarter size hail did not damage them.Under good light conditions, they produce up to 98% of their capacity, with fixed orientation.

Was looking for Z brackets to hang house shutters I made from fence boards. These worked perfectly. I did not want to drill holes in the brick or mortar since the house is 57 years old. Sturdy and easily mounted. Used decorative iron screws to mount them to the fascia board. I was pleased with the finished look.

The pictures show my self-tracking frame for my two 100 watt Newpowa solar panels and a screenshot of the panels' output. The 25 watt solar panels on each side of the frame power a linear actuator for positioning the main panels. They do not contribute to the Newpowa output. Today was mostly cloudy and 72 degrees Fahrenheit. I wasn't expecting great results when I plugged this in to my Bluetti AC180 to recharge it. I was monitoring my Bluetti app throughout the morning, showing 50 to 60 watts input under overcast skies.Then the sun peeked out from the clouds... 201 watts ! I had to take a screenshot! It actually went a bit higher after that. :-)I highly recommend these panels.

I bought this for a large solar panel. It did take a bit to figure out the correct installation for the angle that I needed but it wasn't rocket science. It worked well and has been sturdy for the panel which is on the heavier side.

For this form factor and use case, these panels are a great price. They are (or seem) solidly made, work as they should, and I think are a good physical shape for many uses. I bought the 2x set and then bought another to create 2 strings in parallel. We have a very shaded property so I put one in an area that gets good coverage in the morning and the other in an area for the afternoon. Paired with a good MPPT solar charger and a battery you have a simple and effective system for off-grid applications for a range of projects. I use a simple lead acid battery setup (because I already had one lying around otherwise I would definitely purchase a small Lifepo4 battery for the same purpose) mostly as a buffer to imperfect weather conditions so I can charge up and run my electronics with any of the billions of products available for 12v systems (car/rv/boat) while the sun is shining and don't generally drain the battery at night (lead acid batteries are so fragile to use that significantly reducses their lifetime -- this is why I say buy a Lifepo4 battery [and make sure the MPPT charge controller you buy supports lifepo4 like a good victron model] if you don't already have one)Any negatives of these panels are just the inherent limitations and realities of solar power -- like not reaching maximum power, etc. There are situations where these panels wouldn't be the best choice -- like if you wanted something that had a USB port directly or different type of native connectors (like DC5521 instead of the MC4) but then you need to look into portable solar panels or pay attention to getting the right adapter for the MC4 cables. If you need a portable panel then you will pay more for the same power and they will be larger for the same wattage but if that's what you're after then I definitely recommend that instead. I have a 100w portable, foldable panel with USB A and C plus multiple DC outputs and I love it for what it does. Just figure out your use case and buy the right product for it.
