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…

      It was free to your part of Hobart. eBay wants to charge $40 to deliver this to some parts of Hobart (e.g. Lauderdale, Midway Point).

  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.

    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%.
