ALLPOWERS SP039 600W Monocrystalline Portable Solar Panel Waterproof IP67 RV Solar Panel Kit with 44V Output Foldable Solar Charger for Outdoor Adventures Power Outage Solar Generator

I’ve had these only 2 weeks, but they seem pretty good. They are huge as one reviewer noted, about 6 feet by 6 feet. I’ll build a pvc stand to get all the correct angles during the day. Straight overhead sun and I was getting 493 watts which is a little over 80%. I’m using this to power up an EcoFlow Delta2 Max and wanted just one panel for one of their two solar inputs. I’ll update my review later as I build the stand and play with the panel a little more.Update 1-22-24: I've had this solar panel for about 5 months and it's done a great job. I built a pvc pipe solar panel stand and I can hook this up and get it in the sun in about 3 minutes. I like the small fabric tie-ups - you can fit a skinny Nite-ize tie down though the fabric loop and then wrap it around the pvc pipe - one on each end, one in the middle - both bottom and top of the solar panel. The fabric loops seem to be secured pretty well - we shall see how they hold up over time.I'm still getting somewhere between 475-500 watts on a clear day. And when it's not that sunny, because it's so big, I'm almost always getting 75-100 watts even on cloudy days. When I put this out it REALLY helps to charge my solar generators a lot, lot faster. My home-made solar panel stand helps 'cos I can adjust it to the optimum angle.At this point, for the cost per watt, the light weight, the ease of opening-closing and carrying, this solar panel is absolutely worth the money. Totally recommend.

I have been using this for a while for camping, and I am not very happy with it. The peak voltage is 53v that my battery can not handle. I use an inline 48v to 24v reducer, and usually get almost 350 watts on a bright day, and that is okay. My 5000 btu air conditioner uses almost the same amount of power, and that is what I wanted it for.However, the problem is with mounting. This is a good product and it would have been so much better if it had a good mounting system of some sort. In its current design, it is just a spineless flap that hangs like pasta. Because of its large size, it sometimes is very tricky to mount it properly to keep all the panels exposed correctly. I have tried hanging it on the side of my vehicle, placing it on windshield and hood, and placing it on the roof. There are problems with that. First, my vehicle has got scratched at a few places where it made contact, more aggressively if I hang it on the side. Second, loops at the edges do not appear to be strong. So, hanging over it is not a good idea.It would have been amazing to have some sort of design improvement that can help in mounting it. Because in monger run, it is making me regret buying it.Also, if you are not very familiar with solar panels, just please know that the these are very sensitive to exposure. If you cover a small part of a just one panel, the overall voltage drops remarkably.

I decided that if I needed to go portable what would be the best solar charging setup for a recently purchased ecoflow delta 2 max. After finding another user on a group was successful with using one I decided to purchase 2. Placing them on my roof pointing South this December they produced over 900 watts at one instance noted. Much more when the sky will be clear, and Sun direct, later in Spring. After proving for a few weeks they will be confidently folded back, and placed in storage for future portable use. I highly recommend this panel setup. Amazing.

UPDATE 7/24- The panel completely stopped working and has fallen apart. They have stopped responding to any emails or messages. They have absolutely refused to do any kind of after sale service. Don't spend your money on this panel, or anything form AllPowers. They are a scam of a company.another update - they are still refusing to honor their warranty even though they said they would send me out a replacement. They have blocked my email and have stopped returned messeges on amazon. They even filter and delete reviews on their website. this company is terrible, stay away from them as much as you can!UPDATE to the last update-The panel has lasted less than a year. I have only used it a handfull of times, otherwise it stays folded up and stored inside my trailer. The power output is about 60-70% of what it used to be and a lot of the stiching has come apart. I have contacted AllPowers about a warranty claim. They are blaiming me for the panel falling apart, saying I've damaged it by dragging it on the ground. I've told them that's an incorrect assumtion a couple times and they've told me that it's not covered under warranty and then have blocked my email instead of providing me with solutions. The panel was nice when it was new, hopefully none of you have to deal with AllPowers about a warranty that they don't stand behind.Update - the manufacturer has reached out to me and we have worked through the problem. It is a nice panel, it's freaking huge, 6ft X 6ft. There's no kick stand or anything so it has to be hung up or laying flat. won't be able to use this for my intended purpose and have to find a slightly smaller panel or one with better dimensions for the roof of my camper.Looking at the pictures in the ad and the dimensions given, I thought this panel would work perfectly. However, it shows up and it's not at all like the pictures or dimensions given.
