Renogy200W Portable Solar Panel, IP65 Waterproof Foldable Solar Panel Power Backup, Solar Charger for Power Station RV Camping Off Grid

I bought two, 100 watt panels. Why not just buy the single 200w? I wanted higher voltage. I'm running in series (be careful with this) to achieve the higher voltage = lower line losses and perhaps better MPPT efficiency. AND, I have an Anker C-1000 power station that clips to 10a at lower voltage. So, buying one 200w panel (low voltage) or running two 100w panels in parallel still would clip at 10a even when the panel(s) supply more than the 10a. So, for me, running in parallel wastes some power. Not good.So.. the two 100w matched pair are delivering, at max solar irradiance, about 38v and the 5.34a to the MPPT which is max rated at 12.5a @ 60v -- so I'm well under the ceiling of the power station. BUT this would not be so with some other power stations, so be careful to read specs as you could over-volt your power station and ruin it.My setup for camping: The two panels, the Anker C-1000, 10' 12ga solar MC4 to XT60 connector. (No coupling cables needed for series.) Net output (input at solar station) after panels heat up, is 195 watts. This *could* mean the panels are under spec-ed just a little since I'd expect more like 180 - 185 watts.I'm mostly powering a 12v fridge that has an average draw of about 25 watts. In my state, depending (hugely dependent) on solar irradiance, could hit 1.2kw / day. *Could.* This means I can tolerate a rainy day here and there and still be above water - or perhaps just net-zero, which would be fine, since the power station has 1,000 watts and the watt-hours for the fridge is 600w / 24 hours. So, after about 40 hours and no solar power, I'm out of power. Redundant plan: Two days of rain, I drive to some place and do a fast charge on the power station.These are nice panels for very low cost. IP65, nicely built, great performance, light weight, very easy to deploy. On the IP65, probably not the best idea to get those USB jacks wet.Lastly on the deploy, I stake them out to avoid a gust of wind blowing them over and killing output or worse, destroying the panels.

The panel is great. But, is it for you? That depends....It is well built, reasonably small and portable, it has magnets in the handles, so it snaps shut. There is no carrying case like with the large glass Renogy panels, but it doesn't need one. I charged a 10k power bank with this, a laptop, a camera, a large Anker C1000X power station and it works really well, and given the price I think this is a really good value. The pocket where the hookups are zips on three sides and the zipper is shielded (not fully waterproof, but pretty tight seal, similar to what you see on a high quality rain jacket.). I only wish the pocket was bigger to accommodate larger power banks.This is a 5th Renogy portable panel we have in the house and all of them work flawlessly - we also have the big and heavy 200W Renogy Briefcase panels, which are amazing, but super heavy. I also have a 400W version of this light panel, which is equally amazing and puts out juice close to its rated capacity - I was able to bet 385W from it.That cannot be said of this 100W panel - no matter what I do, I never get over 87W, even on a beautiful clear day with sun directly overhead. That's not the main issue though, it is to be expected as the panel heats up it slightly drops its output and I've yet to find affordable portable panels which reach over 80% of their rated capacity on a clear summer day here in Chicago area. The panel comes with permanently mounted MC4 cable, which is only 3 feet long, give or take. No other cables or adapters are included, so if you power station takes a 9mm barrel, XT60, Anderson, or any other type of solar input socket, be sure to also buy a proper MC4 adapter with this panel... My stations take XT60, but I luckily already had one on hand, yet I bought extras. This is a low voltage panel (See attached pictures for specs) with VOC of 23.4V, so good for charging 12V systems, but not much more than that. And since this is a low voltage panel, if you are planning to buy a long MC4 extension cable to keep the panel in the sun and your device farther away in the shade, get the heaviest and thickest MC4 cable you can stomach. You will thank me for it later. I have a 30 ft 10 gauge pure copper cable and my wattage drop at that distance is less than 10 watts. I also tried a 14 gauge and was barely getting half of the rated power. So, if you buy an MC4 extension, go as short as you possibly can and as heavy gauge as you can afford. 30 feet is way too long for a 20V panel, I know... I bought it, because I double our other panels in series to 45V and get much less power loss. Still the 10ga 30 foot cable weighs almost as much as this panel! So, that's something to consider too, if you wre weight conscious...What I absolutely love about this Renogy 100W is the size and light weight. Would I take it backpacking? No. Would I take it car camping, backyard partying, afternoon picnic or a weekend trip? Any day... and when paired with a decent power station, like my Anker C1000X, this thing can be thrown in the trunk or a car seat and go with you anywhere your car goes.While you are at it, get some bungee cords and ground stakes. The panel has two flimsy adjustable bendy legs, which keep it tilted, but if it gets windy, you will need to stake this down. Because as light as it is, this thing will become a sail on a windy day. Don't ask how I know...What is much more concerning for you as a potential buyer is the output from USB. If you think you can easily power your MacBook Pro with this, don't be fooled. The 100W output is available only via the MC4 connectors, what you will get from the USB-C is 45W (I was never able to get it over 40W) and the other two USB-A ports are less than 15W each when hooked up to a shunt and tested. So, the only way to power a hungry laptop is to have good power station hooked to your laptop and the solar panel charging that station via the MC4 cables at the same time. A clumsy solution, but workable.Would I recommend this panel, despite these shortcomings? 100% yes, any day. I would buy a second one, if I actually needed one. Of course, you could buy cheaper knock offs, which look jut like this, but I'm not sure about their quality, let alone being able to claim any warranty.

Works great with my EcoFlow battery. Kept our EcoFlow charged up to run a starlink and some appliances. Super sturdy, stows easily, and lightweight.

These panels are far better than the Bluetti disasters I bought. They're definitely not hitting 200 W or anywhere near it but they are bringing in around 150W - which is fine for me. They're also nice and light. My only beef is the ridiculous clingly pads on the backs of the panel that the legs, when they are not upright, attach to.Putting these panels up is a chore because once you put one side up, the other legs flop down and get stuck to the pads - so you move to the other end to unstick the pads - only to have the others flop down and get attached to the pads.I can't imagine that whoever put these together field-tested them. It's about the worst design I can think of. (I'm going to cover the stickum pads with tape.Otherwise they're must better than the Bluettis. and I'm fine with them.

Cheaper in price but has all the functionality and value as others. Full sun exposure was 168watts on average. It’s nice that it has some usb ports on it for direct charging. Wish it came with the cord to plug directly into your battery system but they’re cheap enough on their own. Has been holding its own, even with some rough handling. Happy with this purchase.

I love this setup work amazing with RV setup, allows me to point the panel at the sun all day. Easy to fold, lightweight,. Produces great wattage in direct sun

Nice and light and does a great jobPlus plug ins for USB to charge items
