3 x 400W panels outside 24x7 for 125 days straight

We have had 3 of the 400W solar panels outside for 125 days straight, rain, snow, hail, high winds, and no issues. They actually can stand up to sustained use in weather !
I've had them flat on the ground and now on the side of a small rise. Running them in serial. I've gotten up to 960w, yesterday I got 940w late morning.
For 2 months they powered our seedling far in the water shed (pictured to the right in the photo) . Lately they power up all our battery recharging operations - our water filtration and our freeze drier.

Hoked up a single 400 watt panel. I live in orlando florida so sun is always available
With some adjustment it was pushing 300-325. I purchased a second panel but havn’t tried them in series yet. I hope to get 600-700 watts. I think it will do the job with an extra battery.

These panels have far exceeded my expectations. I use these panels in conjunction with my Honda ES2200 to charge my Ecoflow Pro which in turn supplies power to my RV Trailer. The panels typically supply 250 to 275 watts on a sunny day leaning against my trailer. When laid out more flat to the ground I've seen as much as 380 watts.
These panels are heavy and a little pricey, but I believe it's money well spent and plan to purchase at least one more set..

I tried out this 400W solar panel with one of my Delta Pros yesterday. It was a partly sunny day, so the wattage input varied greatly. However, I was able to get up to 367 W of input at one point, and was able to charge from 30% up to 61% within an afternoon. I’m happy with that!

I live in Japan and purchased the Delta Pro / Solar Panel combo. I set up the solar panel by myself and found it quite a cumbersome process. The case is to be used as a "stand" but it was rather tedious to get the panel connected at the 4 attachment points AND attempt to get the panel to sit correctly in the case-stand. After connecting the carabiners to the grommets I feel like there is quite a bit of tension/stress placed on the grommets and I would be concerned about long-term regular use. Seems like a weak point in the design but hey - I'm not a design Engineer. Directions say to zip up the case to adjust the angle of the panel but I'm in a location where I can just leave it completely unzipped. I didn't attempt but I would imagine trying to zip up the already flimsy case while holding the panel would be very frustrating. Two people working together would stand a better chance at not feeling like they deserved an ice-cold beer after wrestling with it alone. Overall build quality seems excellent and I'm glad I have it in case I need it but I hope someone can improve on the design moving forward. Cheers.

Super easy to use flat or even with the included stand.
Charging in a zip too.
You can PARALLEL connect 4 on the Delta Pro.
I would recommend this to a friend!
