Nice very well made, big watts which is what you want, easy to install, nice and sturdy, well made very sharp makes a nice output , highly recommend

I was debating whether I wanted to add Solar to my battery backup system for emergencies. The price of these came down low enough ($0.50/W) that I figured I should just do it. I saw some mixed comments about their performance, but decided that for the price I didn't care if they got to the full rated power. I have a set of 8 of these in series with a MPPT system at 30 deg N latitude in July. The peak power out I've managed to achieve so far is 600 W (rated 800), but I don't have them mounted at the perfect angle at this point, and while it's pretty clear, there may be some high thin clouds, so I'd say that's pretty close to specs. I will say they are _extremely_ sensitive to shading. Shading even one cell in one panel causes a very significant power drop in this configuration, but that behavior is pretty much expected for this type of setup. Assuming you can get these well mounted they are absolutely reasonable for a budget solar setup, and at 18V, you can get them working with the newer high voltage MPPT systems with a small number of cells. I'm very satisfied.

Solid product. Got on sale and worth every penny. I upgraded my old system with these

These solar panels have been put through some harsh temperatures and storms while I cleared my property out to build a cabin and they have worked amazing for 4 months and have been holding up great 👍

Great price and they work great. I bought 3 of these (12 panels) and they work as they should hooked up to my Eco Worthy 48V 5000W AIO system. I had them temporarily hooked up just laying flat on the ground when there was a flash flood. Even under water they were working fine and producing power! They were partially or completely under water for 3 days working and producing power as normal. They still worked fine after digging them out of the mud. I now have 4 of the panels hooked to my 12V system and they work great there too.

Got one with broken clips and one that does not power. Eco told me to deal with Amazon. Amazon needs all 4 back to replace the 2. But I'm using the other two and I'm over 2 hours from a return point. So, if it's only 50% reliable out of the box, how long do I have to last the other 50%? Not happy. Returns for some people and some things are actual WORK. It takes time and money. I'm not here to TEST your panels, I needed them for a project and I got half what I needed. Unless Eco can fix this, I wouldn't buy their stuff.

Good quality, put out between 80 to 85 percent watts per 100 watts panel .as expected. Excellent packaging.I have total of 8 panels.
