A cheapie solar blanket, there's 2 styles, long and narrow, or square. Only buy this if you're willing to return it, it may be a total dud.. Be mindful you generally get what you pay for with this sort of gear, DON'T expect high quality…

I've been debating whether I should post this because there's no chance it will produce anywhere near 200w, maybe 100w, 120w max, if it produces more than that I'd be surprised at the price… It's cheap enough to take a gamble on I think…

The listing claims poly and mono panels in different spots, the usual BS specs, they appear to be poly.. The output is likely to vary a bit depending if you use the included cheapie PWM solar controller or a better MPPT, or if you use the included tiny 5m cable or something better… A rough measurement from the photos it appears there's close to 1 square meter of panels on the square version which in theory should give 150 to 200w, but at this price you really cant expect that IMO… Looking around at Amazon US reviews I found 1 person claiming they only got 33% of rated output, and another that claims 165w on a hazy day, both are possible… https://www.amazon.com/LVYUAN-Monocrystalline-Efficiency-Adv…

I just purchased one of the '200W-ditan' square versions to occy strap to the top of the canopy on a tinny, if it's under 100w I'll happily return it…

Includes: 20A PWM Solar Controller, 5m Anderson cable, 1m Anderson to alligator clip cable,10cm Anderson to XT60 cable. (The 5m cable appears to be very small wire, the losses 'may' be quite high, it 'may' be wise not to use it)

There's a second store with the same price: https://www.ebay.com.au/itm/396228708195

    They processed my 10pm Friday order just after I placed it and sent a tracking number… It's being sent with "PF Logistics" with a "NEXAU######" tracking number…

    My last order that had this kind of shipping was placed on Saturday March 1st, it was processed in Syd on Monday the 3rd, and it was delivered to Hobart on Friday the 8th, it was fairly snappy…

    Be very careful with cheap 200w solar blankets… They would be lucky to get 79 watts….
    Make sure you measure and see years of the actual units.

    I think ops estimates may be optimistic… Happy to be proven wrong.

    • Malik Nasser on 15/03/2025 - 08:23

      It is quite easy to do a basic calculation to get an approximate estimation of output.
      Most of the cheap solar panels on eBay are generally about half of the rated output, but this one seems about right.

      All you have to do is calculate the solar panel area (in m2), use an irradiance value of 1000W/m2, and assume a panel efficiency of about 20%.
      To calculate for these panels:
      Panel 1 is 2.43m x 0.58m which is equal to 1.4094m2. So multiply this by 1000W/m2, and multiply by 0.2 (20% efficiency), which then equals to about 280W.
      Panel 2 is 1.423m x 1.135m which is equal to 1.615m2. Multiplying this by 1000W/m2 and 0.2, equal to about 323W.

      This is a rough calculation only as the panel sizes are actually smaller than the overall dimensions listed.
      However the calculated values are well in excess of 200W, so the listing looks accurate.

      Now look on eBay and check out some of the other solar panel listings. You will notice their calculated area is much less than 1m2, yet they boast a panel rating above 200W. This is not possible for panels with an efficiency of around 20%.

      • King Tightarse on 15/03/2025 - 12:02

        I use the 'real world' guide of (approximately) 125w per M2 for good quality solar blankets.
        It is a rough sketch only but quickly sorts all the fake 'impossible' eBay listings. As such, I would only expect less than 180w from either of these in ideal conditions, if they were good quality. As they are 'mystery quality' I will be really interested to see what figures people get.

    • willyroo on 15/03/2025 - 09:53

      We have a "200 watt" blanket, and it occasionally gets into triple digits on my Victron MPPT regulator.

      In less than perfect conditions, it's a steep drop off.

      The blanket is useful due to its compact folded size, and it can sit on the windscreen charging the battery in the back of the wagon.

      Our 160 watt Kings folding panels are true to label, occasionally hitting over 160 watts. Again using a Victron regulator.

      Of course - YMMV :)

          I have exactly the same ones. I have two of them. I immediately tossed the rubbish PWM regulators they came with, and used a HardKorr branded one. I generally around 6-6.5amps per blanket in good conditions. But they were so stupidly cheap I am happy with that. I think I paid around $60 each from ebay a couple of years ago. I can't find them anywhere anymore.

          I have no experience with Bluetti's but from a quick look it appears you should be ok, just plug the solar blanket straight into the Bluetti solar/PV port using the included XT60 cable, you wont need to use the solar controller included with the blanket because the Bluetti has an inbuilt one…

      I was trying to be realistic and keep expectations in check, they could be terrible or they could be acceptable…

      With the popularity of power-stations and LiFePO4 batteries these days I figured it's a cheap foot in the door for people to get started with solar…

  • cornflakes on 15/03/2025 - 12:47

    Looking through the seller's eBay feedback:

    One person who bought the 400W panels said: "the most I have been able to get out of each set is around ~280w with usual production around 200w"

    Another: " I opened it up and connected it to my Bluetti power station and it was charging at 175 watts just laying on the ground. Very nice price for a 300 watt folding solar panel "

    So probably 100W average for these 200W panels shrugs

    • FLICKIT on 16/03/2025 - 00:29

      The cheap ones like this would probably perish in time, blankets are more just a portable temporary thing… There's compromises with these for portability…

      You'd be much better off with a rigid panel if you need a more permanent solution, a single one or folding pair, they tend to be cheaper per watt, more efficient, and even the cheap ones last an easy decade, 20 years for better ones…

      mine arrived too - plugged into the bluetti ac2a I'm getting an input of 100w so far - not really positioned ideally tbh - just laid flat rather than facing the sun…

      • FLICKIT on 20/03/2025 - 15:24

        Excellent, that's about what I expected, odds are you'll get more with it angled well, 120W or maybe a little more… Considering the price I think this is reasonable but there was a worry it might be a total dud and be less than 100W, lol…

        Are you using the 5m cable that came with it?

        Mine probably wont arrive until Saturday or Monday…

        • evanssm2jp on 20/03/2025 - 15:37
          +1

          Yes using the included cable - I think the main anderson connector is about 5m then the 10cm xt60 adapter..

          I also came with battery clips and a 20a charge controller which I likely won't use but for the $79.99 price I think well worth having

          • FLICKIT on 20/03/2025 - 15:58

            @evanssm2jp: The 5m Anderson to Anderson cable looks very thin, there's a good chance it will cause a 5% or more loss… When mine arrives I'll test it compared to a beefier cable and report back….

            The cheapie PWM controllers are fairly inefficient, good for a spare and that's about it, modern style MPPT controllers and the ones included in things likely the Bluetti would be significantly better I think… I'll test that also and compare it to a Victron…

            Due to the price I took the gamble and order 2 of the square ones to use in my tinny to help top up a 200Ah battery, so I'm pleased to hear you're getting 100w, that was the minimum I'd be content with…

            • evanssm2jp on 20/03/2025 - 17:03

              @FLICKIT: Yeah - it's a fairly thin flat cable and I did notice it getting a little warm just where the cable join is before the fuse so another cable wouldn't be a bad idea I guess…

              • FLICKIT on 20/03/2025 - 17:21
                +1

                @evanssm2jp: Heat = significant losses, that cable will be fine if you're not chasing best performance, but in an ideal world a beefier cable would be good…

                Copper is expensive, so you get what you pay for..

    Noticed that Kings had their 200w folding panel yesterday for $149. Apparently it DOES get quite close to the claimed 200w. Signing up to their newsletter will give you another $10 off. Seems like a good deal @ $139 if you can travel with the folding panels instead of the blankets.

    • FLICKIT on 20/03/2025 - 17:04
      +1

      Ahhh, that's a rigid folding panel, 700mm x 800mm folded, rigid panels always do significantly better than blankets, the glass lets more light through and such, usually better quality in general…

      I assume it's this one:
      https://pricewatcher.au/4wdsupa/kings-200w-folding-solar-pan…
      https://www.4wdsupacentre.com.au/solar-power/folding-solar-p…
      They charge more for the storage bag… Bundled with the bag it looks like the cheapest it has been is $198..
      https://pricewatcher.au/4wdsupa/kings-200w-folding-solar-pan…

      I have lots of rigid panels but I needed a couple with a small packed size for tinny trips, and so I can throw one on top of a soft Bimini canopy on a tinny… (plus cheap was important because they're likely to get damaged in time, lol)

      • HappyPants on 20/03/2025 - 17:21
        +1

        Yeah that is the one. Absolutely understand this is not what you are looking for, just thought it might help someone. It was definitely $149 yesterday, but without the bag. Excellent watt per $ value, but yeah, if you need a blanket you need a blanket.

        By my rough maths if these folding blankets do 100w then that is $0.80 per watt.
        The Kings folding panels, lets say they do 180w (and by most reviews they do this easily) then its roughly $0.77c per watt.

        It's just an option, thought I would throw it out there. It was only a 1 day sale, but as we all know, that price will be back for sure, normally don't have to wait very long.

        Definitely would have to manufacture some sort of bag though, to protect the glass panels.

      You really don't need to use the cheap PWM solar charge controller, you can plug the panel straight into the Bluetti, as per page 15 of the Bluetti manual:
      https://cdn.shopify.com/s/files/1/0558/1199/7864/files/AC2A_…
      "Voc: 12V-28V Current: 8.2A Max. Power: 200W Max", … The panel max voltage is only like 24v, so you're all good….

      With using the cheap PWM charge controller, they're quite inefficient, and the Bluetti has it's own built in MPPT solar charge controller, so you'd be getting decent losses by going through both, they may even fight against each other, I'm not sure… (I'd only use those cheap charge controllers as a last resort, they're so cheap and nasty I dont really trust them, lol)

      Edit: More info here:
      https://www.bluettipower.eu/blogs/news/mppt-solar-charge-con…

    • FLICKIT on 21/03/2025 - 15:41

      To add… Looking at the readings from the PWM controller in your video, and looking at a manual for the same generic controllers, it appears the PWM controller has detected you have a 24v battery, and set the float voltage to 27.4v for a lead-acid battery, so it would probably just be passing through the full solar voltage which is well below at ~16v…. (a PWM controller cant increase the voltage)

      • Gomo on 21/03/2025 - 16:18

        Gotcha, regardless if I connect the unit directly the output power was the same 😅

        • FLICKIT on 21/03/2025 - 16:49

          Yeh, if the PWM was set to a 12v battery then it would have been hacking the ~16v-18v down to ~14v and that's where the losses would come into it…

          I still wouldn't use it though, lol

          • Gomo on 21/03/2025 - 23:02

    I just unpacked my square ones for a quick look… They're mono panels, 12 x half cells per segment = 108 total, the 9 segments are about 345mm square each, so 1.07m2 of panel surface…

    My initial impression is they look good considering the price, better than I expected, you wouldn't call them high quality but they're good for the price… From a quick look the cell connecting tracks and such are a little rough in spots, odd imperfections and such, but that's probably fairly standard for cheaper panels…

    I cant really test the output right now because my lithium batteries are all charged up ready for going away in the morning, so I'll test them while away and test the cable and PWM controller when I get back…

    I was a bit nervous about the PFL shipping (PF Logistics - Freightster), they seem to have a bit of a bad reputation, but the boxes weren't knocked around or anything, very slight denting on the corners but it certainly doesn't appear the boxes have been thrown around or anything, which is something I was worried about… .

    So far I'll class this as a win, lol, time will tell though…

    • FLICKIT on 24/03/2025 - 16:54

      To add to this… Tighten the screw terminals on the PWM solar controller if you're going to use it, they're not really tight… All the terminals on both of mine you could near call loose ;)

    I haven't done any real testing yet but I threw one of my square blankets on top of the Bimini canopy on my tinny and left it there for a few days, heavy dews every morning and a day of rain, it handled it all fine… Laying flat like that it averaged 100w to 125w most the time when it was sunny, I saw peaks around 150w at times and according to the Victron solar controller it peaked at 173w… Over the 6 days or so I had it up it produced 2450Wh, about 200AH… A couple of days were very overcast/rainy and I was often in shadow due to poking up a steep river valley, but I'm happy with it…

    The square version has small lightweight tiedown loops which don't seem very sturdy, I cant see them lasting doing what I'm doing, I might sew some decent webbing straps with eyelets onto it eventually…

    I'm using it to charge a 200AH battery setup I built for the Electric trolling motor: https://imgur.com/a/8HOdace

    When I get a decent sunny day down here I'll hang a blanket up at a good angle and do some decent testing, just out of interest…

      Nothing special, just some random footage to show how I'm using mine, excuse the mumbling and errors, I don't prep and generally don't narrate: https://youtu.be/vGIrULVZA0U

      Can I please ask which size Toolpro case are you using there? I think they are on special at Supercheap at the moment. Looks incredibly neat. Would love to copy it. I have almost the exact same components ready to go, just not quite the confidence yet to carry it out. 😬🤔

      Edit: Looks like you have a total of 4 input/outputs, is that correct? Two Andersons on each side?

        It's the extra large: https://www.supercheapauto.com.au/p/toolpro-toolpro-safe-cas…
        External Dimensions: 560 (W) x 430 (D) x 215mm(H)
        Internal Dimensions: 500 (W) x 350 (D) x 190mm (H)

        It's a bit on the big side really but all the smaller cases at SCA and Bunnings weren't quite big enough… I also looked at other tool boxes, eski's, and such but this case was the only one big enough and semi-suitable for the 200AH…

        I went overboard with the battery mounts due to using it in the tinny with the jarring and bouncing around, for general use you could just strap the battery in fairly basically…

        I also added a strap inside because the top of the case was bowing up due to the ~20kg weight when I picked it up by the handle: https://imgur.com/DtMYZcp

        In the top there's a piece of 10mm thick white cutting board plastic which I screwed the shunt and such to… The posts for the mega-fuse are just countersunk 8mm bolts mounted through the plastic with a washer and nut on top, then another washer and nut on top of the lugs, you can buy proper studs and such but I was just using what I had on hand…

        Those anderson sockets are quite good for the price, $22 for 2 x doubles: https://www.ebay.com.au/itm/396182574616

        I usually solder lugs and anderson terminals but being lazy I just used a cheap ebay manual hex crimpers for the lugs, it did the job fine, I might solder them also later if I can be bothered: https://www.ebay.com.au/itm/167236904502 (in the past I've purchased 2 of those cheap yellow hydraulic hex crimpers but they were pretty crappy, one the dies didn't line up and it mangled the crimps, the other leaked oil)…

        It's best not to buy cheap ebay lug terminals, they're really thin and crap, they tend to crack if you bend them and such, electrical/electrican supply stores sell good quality ones for about $1 each, just google > electrical supplier in your area < to find them…

        Fun project ;)

        Edit: in regard to your edit… Yeh, just the 2 x 50amp andersons each side, they're apparently ok for up to 120amps if you dont unplug them under load, more than enough for my current needs… Down the track if I ever buy like a 2000w inverter or such I might install a 170amp Anderson for it…

        I haven't added fuses or breakers for the individual Andersons because everything I'll be plugging into it has it's own protection… I figure the battery BMS protection and the 300A fuse are adequate to protect the battery and wiring…

          I love the whole build. Everything you need, but nothing you don't. Thanks for your complex reply too. It'll help me to just get stuck in and started.
          I enjoyed watching the video on the panels too. A beautiful spot, especially the last few moments in the vid. All that preparation is worth it for a view like that.

            @HappyPants: Thanks… I considered mounting a DC-DC charger and/or MPPT in there but space was tight and I really didn't want the heat from them in the sealed box with the battery, I considered external heat-sinks and such but it wouldn't be ideal… Using it in the boat vents and fans aren't an option…

            That's up the Gordon River in remote Western Tasmania, World Heritage Area, I LOVE it up there, rain forests, huon pines, and lots of history to hunt out and poke around, convict, piner, and Hydo history, it's where they wanted to build the Gordon Below Franklin hydro dam in the 80's which sparked huge protests and such… https://en.wikipedia.org/wiki/Franklin_Dam_controversy

            @HappyPants: I just noticed that ebay listing for the crimpers has gone up to $24 from the $20 I paid, so if you go for crimpers like that search around and find a cheaper listing..

            The die on those crimpers is fairly narrow so you have to do 2 crimps, like: https://www.powerandcables.com/wp-content/uploads/2018/09/He…
