SP027 100W Foldable Solar Panel,23% Efficient IP67 Waterproof for Power Station, Camping, RV&Home Use, Compact Portable Design（SP027-100W

2021 AllPowers 120 watt Solar Panel I already have an AllPowers 372Wh Power Station Generator. Which works great. I have used it to power lights and fans during a power outage. Also used it to power Christmas lights on my pontoon boat this year. The Power Station is easy to use, well built and even supports Bluetooth connectivity through an app on my iPhone. I compared many brands before choosing Allpowers. In the end AllPowers offered the most features, quality and value for the price. Very glad I made the Allpowers choice and highly recommended it. I am an AllPowers fan. Anytime I have contacted AllPowers support they have been quick to respond, knowledgeable about their products and very willing to engage on resolving my issues. Now I am trying the new AllPowers 120 watt Solar Panel, to charge my AllPowers power station generator. This panel is capable of charging any Brand of generator/power station or other project needing solar power; As it comes with a wide variety of connectors and adapters. My AP power station can use AC wall power, a DC 5.5 x 2.1mm barrel plug or an Anderson connector to charge. This panel comes with both DC5521 and Anderson connected, as well as adapters for many other needs. It’s size and weight is what surprised me the most. At 22 x 14.2 x 2 when folded, it is just two notebook paper pages tall by a little more than one sheet of notebook paper (landscape) wide. When fully open it is 22 x 60 inches, much smaller than similar wattage panels. I believe this is because this newer panel is more solar efficient than older style panels @ (21%). Ultimately this means this panel has a faster charge time, is lighter weight and is smaller size than similar older panels on the market. It comes with a built in charge controller that manages the various voltage and amperage power out of the panel. For example the MP4 solar connector provides 21v at 20A, DC ports provide 12v at 10amps, USB ports provide 5v at 2.4amps and DC 18v at 3amps for a laptop. You can also chain two of theses panels together to get more amperage for even more power and faster charging times. All right out of the box. Overall this is an impressive foldable solar panel with all of the features and adapters you may need, faster charge times, better solar efficiency, lighter weight and smaller size than comparable panels. I continue to be amazed at the AllPowers products. The quality and features they offer are first rate and are offered at a very reasonable price point.

I wish I could give this 4.5 stars because this is a great value that does what it is supposed to, but isn't as universal as some may think. For the record, this review is as much information sharing as anything. 2024 UPDATE: More details on watts produced TL;DR: Works with Bluetti power station but you need to buy an XT60 adaptor or use the cables provided with the power station if you have them. Panels are wired in parallel which is good for partial shade. Was able to get 60W in less than ideal situation so you can charge a 500Wh power station throughout the day. Best output watts I have seen is ~80W Good value, but not flawless. I bought this for $125 to use with my Bluetti EB55. I didn't want to pay $500 for 200W panels from the manufacturer, but wanted a bit more than what the knock off 100W panels offered. This was a good compromise. Despite having lots of different adaptors in the box, I had to purchase an Anderson to XT60 adaptor to get this to work on my unit. Allpowers provides a barrel plug that fits the input for the Bluetti, but that particular jack requires 20V to work and this panel wasn't able to provide it. By going with the Anderson to XT60 (I originally thought they were the same thing, but they are not), I was able to get things working. (Edit to add: I later realized my power station came with the cables needed.) Two important details about these panels that are worth noting: crystalline structure and parallel vs series wiring. First, these panels use polycrystalline silicon instead of monocrystalline like some of the more expensive models. Essentially it is a bunch of small pieces instead of one big one. People talk about mono being more efficient, but in my experience that has more to do with surface area required than with anything else. Since poly is cheaper, if you want to save a few bucks you can use it, but you will need slightly larger panels to get the same wattage. But if you are purchasing based on output and price, it doesn't matter. The second item is related to how the individual panels are wired -- either in series or parallel. Without getting too technical, if a multi panel unit like this one is wired in series, then if one panel is partially 50% shaded then the overall output will be 50% less even if the other panels are in the full sun. However, if say a 4 panel design is wired in parallel, and one panel is 50% shaded, your output power will only drop by about 12.5% if all the others are in full sun. These panels are wired in parallel which is great and something I was originally worried about. Now let's talk about output. It is winter here as I am reviewing this. The sun never gets very high in the sky, it is hazy, the days are short, and since I live in the woods, everything has at least some shade from leafless branches. It is close to worse case scenario for a "sunny day" I will encounter. In these circumstances I am about 60W just setting things up quickly and not being too particular about alignment. 60W out of panels advertised for 140W doesn't sound very good, but it was much better than I was expecting given the circumstances. Since the EB55 is 537Wh unit, I know that even in less than ideal situations, this will be enough to charge it over the course of a day. UPDATE: Running these in full sun near the solstice at mid day, I was getting outputs of around 75-85 watts, so that is what I am using for best case scenario. Given that ~500Wh power stations cost $500 on their own, I was not eager to basically double that amount to add solar functionality. I am very pleased to be able to recharge every day while spending less than $150. Since this is technically a review, let me drop a few other quick thoughts on the unit. - There are lots of adaptors you can use that come with the panel, but don't assume that just because it fits it will meet the needs of your device. - The alligator clips they include are basically useless since it can be dangerous to try and charge a battery without a power control unit. - The USB controller is nice and having it work with USB-A and USB-C is a perk. Can't really think of a situation where I would bring this but not my Bluetti, but still a good perk. - The pouch is nice to have to keep all the wires. - I like that if I decide I do need more power, I can buy another unit and wire it together with this one. - It is a bit heavier and bigger than expected, but not burdensome. Final verdict: Great value if you want solar charging and can work around the limitations.

Panels, especially folding ones, never meet my expectations as far as output, until I realized REAL WORLD output and RATED POWER are two different things. This applies to ALL PV (Solar) PANELS not just All Power. More below but first the overall impression. ALL POWER comes with a good variety of useful accessories and the design is good, quality is very good for price. I got it for $239. That is a good price compared to other brands that may cost $400-$800. Are the other brands better? IDK? You would expect more for the price, but not necessarily. The fold out kickstands works well. I like how they have a pocked for the panel output cables and accessories YES the power cables leads are short which is fine with me, so the cables can store in pocket.... They use high quality cable and connectors. I have extension power cables so my devices are in the sade... panel in sun. RATED POWER - The big variable besides sunlight hitting the panel, no shade even just a corner kills output, aiming the panel at sun, how hot the panel, is what is the panel connected to. What are you trying to power (Load/Drain). Typically it is a battery you are charging to provide power to the devices you want to power. More accurately it is a BATTERY CHARGER or battery controller you connect the panel to. Sometimes those are a discreate device, other times integrated in a POWER STATION with the battery. Not all controllers love DC power direct from a PV (Photovoltaic) Solar Panel. Some battery charging controllers are optimized for one solar panels but may not be optimal for another brand of solar panel. Does not mean the panel is bad, just mis-matched. Spoiler Alert, ALL POWER does meet it's rating 200W, but for my actual usage I could only extract about 125W for my application. This is normal. I compared All Power to two 100W high end ridged panels (big and heavy) in parallel, they do the same thing in my application. Although the ridged panels consistently had about 10% to 12% more Real World output. Not a big deal. The point being both panels did not make 200W in my application... but both tested to their rated 200W. RATED POWER... How to measure. In strong full sunlight mid day w/ panels angled right at sun, using a volt meter check open voltage. This is with no device connected. You will see 20V give or take. Then check shorted amps, with an Amp meter able to measure at least 12 Amps DC (you can do this in series with meter leads or clamp on DC Amp Meter). I measured 20V open and 10.18Amps Short. (NOTE WHEN YOU SHORT THE + and - YOU WILL GET A SPARK. IT IS OK). ALL POWER, 203.4 Watts under the conditions it was tested under... However when connected to REAL WORLD load the actual power it is normal to get less Wattage due to mismatch with controller and that solar panel design. I DO NOT KNOW if $800 panel similarly rated will do much better. I would hope so, but who knows. My application is a 500W POWER STATION to run a 12V Frig/Freeze when camping. The Frig in moderate outside temps can run 24 hours on the Power station, about 24Watts an hour. The charge controller in my power station LIKES 24V, and limits charging to 125 watts (to protect the internal batteries). Voltage can be from 12v to 30v but anything under 20 volts the charging drops off. I tried to charge the power station off car's 12v jack (13-14v) and it was pathetic. So it is not all the Solar panels fault. Most panels open circuit make 20 volts, but under load the volts drop to 14-17 volts... this is normal and some charging controllers don't like lower voltages. *That is why I use a boost converter to charge my Power Station from Solar panels.* TIP I USE A BOOST (bucking type) Converter to get voltage to 24V regardless of input voltage (output from panels). The panels are going to be well below their OPEN voltage, often in 15v-17v range. Better more advanced (expensive) power stations may be more flexible. So my charger sees 24 volts and at what ever the current (Amps) are and charges most efficiently. If there are clouds and panel drops too low the booster drops out and you are no longer charging. It really is great in that with low morning or late afternoon light it continues to charge without dropping off as it does when panels are directly connected to Pwr Station. My Renogy 2x 100W panels behave in a similar way with this power station as the All Power panel. Some combination of power station and panels do better than others. SIDE BY SIDE COMPARISON WITH ALL POWER (portable folding) and TWO Ridged 100W Renogy panels in parallel. The Renogy panels were better, typically 12% give or take, about 9 to 12 watts more. This is to be expected being ridged panels. But ALL POWER surprised me and did better than I thought. I had other 200W folding panels and they could only muster 80W... All power was doing 117W. NOTE One advantage of having two 100W panels (Renogy) is you can put them in series and double voltage and cut Amps in half saving "IR" loss. The HIGHER VOLTS the LOWER AMPS for same POWER (watts). This means less loss over extension cable. I have long extensions (V x Amps = Watts). This is why the power grid bring power to your home is very high volts like 100,000 volts, but AC. I have another converter or BUCK converter to take the 38volts from the Renogy panels in series and drop down to 24 Watts (ideal volts for my Pwr Station controller). My power station is limited to 30V max. I can not run the two panels in series directly. So I have a BOOST converter and a BUCK (or drop down) converter. Note you can run to ALL POWERS in parallel and get more power (double). SIZE MATTERS... Clearly stored the ALL POWER is a winner. It is about 25" x 20" folded and fairly thin. However unfolded it is 25" x 80" = 2000 sq-in or 13.8 sq-ft it is large.... The ridged Renogy 100W panels size are 41"x 20" = 820 sq-in each, 1640 sq-in for two, or 11.4 sq-ft. However when the two Renogy panels are stored in their cardboard shipping box, it is awkward and heavy to move. The Renogy panels are about 1.5 inch thick, so two in packing box is about 5" deep. The thickness of the All Power panels are thin. However not too thin they are too floppy. The All Power I think is about 10 lbs less than th ridged Renogy. Add a handle, less weight, thin compact the All Power is easy to move around.. However folded out the ALL POWER IS BIG... The KICK Stand is nice. In wind take care it does not blow down or away. People expect to ALWAYS to get rated power no matter what. That is of course not possible. In fact it is unlikely you will ever get more than 50%-70% unless everything is optimal. Besides the mismatch between battery charger I explored above, obviously sunlight can be filtered (cloudy), panels not ideally aimed at sun, hot temperatures, all produce less power than rated. However if testing the panels under standard testing criteria, they produce rated power, current, volts. However real world is not test conditions. ALL PANELS DO THE SAME THING. I need to generate about 500 watts per day to keep my good sized portable 12V DC refrigerator/freezer running by charging the battery station fully before sunset. I can expect to make that over a 8-10 hr sunny day easy and then some. Overnight, say 12 hours my Frig uses about 250 watts. I need to keep the Rrig running and charging battery (250W + 250W = 500W) throughout the day before nightfall. 200Watt panels that make 120W to 140W real world with no clouds is plenty. However if cloudy more panel may make the difference. I tried to lay them flat on roof luggage rack. It was marginal. Angling them makes a huge difference. Also on marginal day bigger or more capacity panels helps a lot. I found a sweet spot for my camping Frig, but you never can have too much power. I would do well to get more panels and1000W power stations but price and weight goes up significantly. Right now I am good enough and still have room to spare for charging phones. HOT DAYS AND 12V FRIG. Last time I was camping a full week it was mid 90's, I was using much more power (Frig running much longer due to not getting to set temp during peak temp of day). I had to run the Regurgitator at 38F verses 32F so it ran a little less. Drinks are still cold at 38F, especially when it is in the high 90's. Also even though set at 38F it is colder at bottom of Frig is close to 32F. Guess where the beer went?

Edit: 6 months later… I’ve had it for around 6 months and it’s worked well when I’ve used it. I’m still very worried about its longevity - roof mounted panels will last years and years without so much as a scratch…this thing as it’s put up and taken down often…it may last 2 years tops. It is very heavy too. I carry it with one hand but wouldn’t trust most of my family to be able to. I see bubbling under some of the solar modules, and I’m sure it’s effecting performance. Now in full sun I’m lucky to get 300w typically. I will say as far as technical support and warranty are concerned - they sent me a replacement VERY quick after discovering that something shorted out on my panel. The voltage dropped at that time to 1v, but was still existing so it wasn’t an open circuit….ive actually fixed that panel by cutting it all open and replaced a diode and it’s working just as well (but more bubbling under the modules, so I expect it’s just an age thing) Original post: So far, amazing. I have this plugged into a set of homemade extensions (16ga CCA wire) followed by a set of 20ft extensions purchased on Amazon and delivered yesterday - into a bluetti AC200 MAX’s solar input. First day of original setup, I was getting 40-60w while terribly overcast at 5pm, so the sun was super low and ridiculously covered. The second day (full day of high sun, but also ridiculously overcast, picture of said sun and clouds) I was pulling a solid 130w all day long. Not bad considering (funny enough a Solar prediction app I have suggested I’d make so little with the weather that day that it would hardly offset the bluetti operating wattage….it was far exceeding that) TODAY is a sunny day, and so far today I pulled 397 watts for a few minutes…altogether it’s partly cloudy now, so I’ll watch it hit 390 then simmer to 130 or so (I’d say on my setup the 130-150 is about baseline that I can always expect to hit) It’s setup in the yard, pointed directly at the sun, but the wattage peaked to where I wanted it to for sure. Cons: So far it feels fragile…more fragile than I care to admit. This may be a solar suitcase, but these are NOT flexible panels, so if you were to have them drop on something while carrying to setup, you will likely damage them? Not sure, don’t want to find out. Be careful with them. (I’m knocking a star down on portability only for this reason, but it’s almost to be expected this thing is big and fragile) Because of the sheer size and weight, this means the wind can easily take this thing and flip it/flatten it. If so, be careful about what you put underneath it or around it as well as the terrain it’s on. (There are nice little loops to secure it to something if you wish to do so on the top and bottom between the panels) Altogether I got this for a really good deal with discounts and promotions and am EXTREMELY happy with its performance. I full time in an RV, and had yet to get Solar and while I’m building out a legit rooftop array, I purchased this so at least I’m making some production and offset my ‘always on electronics’. This will easily stay in my arsenal and probably purchase a second because the bluetti can take in quite a few more watts of Solar and this thing is worth it that’s for sure. I’ll update after some time owning it for longevity sake!

I purchased the 140W Allpowers solar panel about a year ago, and it worked fine for my needs at the time: camping, re-charging portable generators, cell phone, laptop, etc. I use a powered telescope, and with it the portable generators and laptop. Suffice it to say that the 140W solar panel was adequate. HOWEVER, it is about a year later, and I needed to buy a larger battery pack or generator I could run at night while camping. Hence, I needed more power to recharge said generator/battery pack Seeking affordability, I once again bought the Allpowers 140W solar panel. And then . . . it began. I could see on my batter pack, a Generac GB1000, that my input wattage from a single 140W solar panel was 40W, varying and fluctuating, but also increasing as the day progressed. Prior to connecting the solar panel(s), I measured voltages of each, one panel at about 21VDC, and the other at 20.3VDC. I connected them in series, and measured 38VDC at one point, and then 42VDC at another. I'll chalk this up to the saturation of the solar cells as the day progresses. But to charge the Generac, the specs on the Generac say that the max voltage to charge the Generac is 28VDC. Therefore, charging with the solar panels in series is a no-go. Hence, I had to connect them in parallel, in which case, I measured voltage at 20.2VDC. Connected to the Generac in parallel, the input power indication is 67W, going as high as 77W, but generally holding at 67W. So that's 2 x 140W solar panels in parallel measuring at 67W input to the Generac. Total power, however, with 2 x 140W solar panels should be 280W. However, reading the specs on Amazon for the Allpowers 140W solar panel, they indicate 140W Peak Power. So taking 140W peak power and dividing that by the square root of 2 gives me about 98.99W. So, 67W compared to 98.99 is 67% of that power OR: let's take 67W and change that to a peak value: 67W x the square root of 2= 94.75W. So 94.75W x (100/280) = 33.84% of the rated power with 2 x 140W panels in parallel. Now let's take the 40W value from a single panel, and change that to a peak value: 40W x the square root of 2= 56.57W. So, 56.57 x (100/140)= 40.4% of the rated power of a single panel. Whether we use percentages, or just what we see in the measurement of power, the 140W Allpowers solar panel is not producing 140W peak power. Indeed, there are variables to consider, such as placement of the panels with relation to the sun. Maybe the lead engineer in research and development at Allpowers was having a bad day and happened to be using a broken calculator. Maybe quality assurance at Allpowers doesn't have a strict testing protocol where the outputs are measured. I don't know what the test conditions were in designing or how the manufacturer arrived at 140W peak power, which by the way, is an easy defense for them if one doesn't know how to arrive at these numbers using the right calculations. Just based on my voltage measurements, power indications, and calculations, the Allpowers 140W solar panel is NOT as advertised, and hasn't come close to producing the rated peak power. Take what you will from it, be your best self, do you, and make the decision that works for you. As for me, even if a $1k solar panel produces the advertised rated output, I couldn't afford it anyway. This particular solar panel has been adequate to my needs, albeit OVERRATED and with that, probably OVERPRICED. And in case you're wondering, I have a background as an electronics test technician for aerospace, a background as a robotics technician, a former electronic technician in animation and production, and I am currently an electrical test technician in power utilities (just in case Allpowers has a need to know).

I saw some of the videos about this solar panel array and I knew it would be the best choice for my portable power stations. Not only is it one of the largest Watt portable panels available, it also has impressive charging capabilities in terms of output compared to other panel units. Another great feature is the fact that it is a fully portable unit and can be folded up and moved as needed. The only drawback is you really need a frame or something to hang it off of unless you want to put it down on the ground directly. This is not an issue to me but some have complained a bit about it so I thought I would mention it. Finally, if you can find this unit on Prime Day or another sale like I did, the price point is fantastic. At one time this unit was around 700, but I got it for less than half that and it's usually in the 400's range. Can't beat that.

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 just got it, but on the first test, in Northeast winter sun, about 1:30PM, it was delivering over 300W, it was up to about 298-305. The sun could have been better, but this was my only chance to try it out. I have used many panels and power stations, and know what to expect in my area, during which seasons and times of day.... I give it a five star, because, honestly, I was thinking if under these non=perfect conditions I kicked at 275, it would be a keeper. I am using it on my Oukitel 2000 and it is really drinking in the watts. I also have Jackerys... two 1000s and one 1500. The 1000s can only take in 200W so won't test with this panel, but the 1500 can take 400W. It has its own panels, but putting up just one, though large, will be easier than hooking up four 100W and dragging them around the yard to track the sun. It should work. As for weight, it's pretty heavy, but not horrible. The handle seems solid for carrying. It was not very floppy at all, so the rigidity, likely requires more weight, and the trade off is worth having something fairly solid. Waterproof...I can't tell, but to extend its life I prefer to leave it inside when not in use. I'd think the canvas cover could get soaked, but doesn't seem like it would hurt anything. I have bought and returned another panel, 300W which only did what two 100W jackery panels chained did. I returned that and with discounts and promos, was able to put the money towards this panel, which is by far, way better. We get a lot of power outs, and this panel allows me to charge the Oukitel 2000 in...even these conditions, between 6-7 hours. Less time with better conditions. If I ever expand to a larger battery backup, considering a second 400W panel to link together. The little booklet that is with this explains how. Also it had a lot ao nice adapter ends included. The main cord from the panel is MC4, and the Oukitel's MC4 to Anderson input cable worked perfectly. Very happy....I have been at this for 12 years now and have seen and tried so many panels, and power stations, and this one is Class A...though I have had it only a day, so will have to see how it endures....but not worried...it's very well made.
