🌞【 ULTRA FLEXIBLE 】 Flexible solar panels works as great options for installation and transportation application such as RVs , boats and curved place. Bendable design make it a great solutions for off-grid system such as Roof top, Campers, Trailers, Boats, Cabins, Sheds, Tents, Yachts and any curvy or uneven surfaces.
🌞【 HIGH EFFICIENT 】 Constructed of premium monocrystalline solar cells with max 23% efficiency; Advanced ETFE material helps to reduce light reflection and enhances solar light capture and electrical performance. The multi-layered ETFE lamination also enhanced the cell performance and extended lifespan, can last for years !
🌞【 MPPT CHARGE CONTROLLER 】 Equipped with an intelligent MPPT charge controller to charge multiple 12 volt batteries including AGM, Gel, Flooded and Lithium Battery. The solar controller also built-in internal protection system to provide full protection for the battery from over charge, over dis-charge, over voltage, over current, voltage, short-circuit etc. The visual LCD display helps to monitor the real time working status of the solar panels and battery condition.
🌞【 LIGHTWEIGHT & DURABLE】Super thin of 0.18inch and lightweight, which is only a quarter of its traditional 100 watt solar panels allowing transportation and installation a breeze. IP67-rated junction box to effectively block water splashes and dust from outside, great for out door use. Durable and weatherproof material enabling it to withstand up to 5400 Pa of heavy snow load and up to 2400 Pa of high wind.
🌞【 WIDELY APPLICATION 】The box includes a full sets of flexible solar panels 100w, MPPT charge controller, 2 SAE connector extension cable with alligator clip cable and o-ring terminal, great flexible solar for outdoor activities like camping, off-grid road trip and unexpected power outages, etc. SAE connector, quickly connect or disconnect. compatible with most of the SAE adapters on the market.

So far had it out a couple times and in mostly direct sunlight I was able to get around 45 to 50 watts output from the charger controller charging an LFP battery, haven’t tested the output directly. Not as light as a flexible full size panel but more portable.

Upon receiving the panel it was almost as if it had not been fully completed? It works as described.

I was going to use this to power my portable fridge/freezer but it is nowhere near the 55 watts its says it can produce. now if it was like 40-45 watts then I would say that’s good enough for the price but the most I saw from this panel was 23 watts in direct sun at noon. That’s not even half of the advertised amount. This panel will not produce any power unless it is direct sun and facing it. If there is the smallest cloud or its not perfectly parallel to the sun you get even less watts or even nothing.

Because of the limited charging capacity, I plan to purchase another one to connect in parallel. This combination will maintain my 12 volt agm battery will powering my electronics and a fan during an extended power outage.

I’ve mostly used this to charge batteries: and for this it works perfectly. What I like: 1) quality (it feels solid, and looks like it will last being carted around), 2) the carrying case is not some flimsy grocery plastic bag quality case – it’s a real cloth stitched, 3) a plethora of cords for every connection type, 4) the fact that it’s two pieces and can be angled towards the sun is very useful. What could be better: there could be a pouch on the carry case for all the cords, and 2) possibly the efficiency of the panels could be better (when it was sunny and light was direct, the output was great / when it was cloudy it seemed to struggle a little with the current. It still did charge both my snowmobile and motorcycle battery in a couple of hours. If it did this – it should be overkill for things like cell-phones and other battery-backup generators. Overall I am pleased.

I was looking for a reliable portable soar panel for mixed use (charge auto battery, phone, tablet, & other portable devices). I have installed fixed panels on my RV’s since 2004 and enjoyed the freedom they provided. The portable panel had a high bar to meet for me to like it. I purchased several “cheap” systems in the 30 to 60 W range and 3 were junk (but they were really cheap). The 4th system was reasonably good but not easily portable and not cheap. The Allto Solar system while not cheap ticked all the boxes and had some bonus points. The folding system is a reasonable size and comes with most of the cables you would need (except the USB charging cables which came with those devices). When I connected a USB-C phone it was charged at hi power, and my tablet didn’t complain about “low power charging”. Using the supplied cables & controller I was able to get a charge rate of 2.4A into a small battery that was almost dead. This was done in February in Florida on a sunny day (which was better than any of the other systems I tested). In my short time test, this is the system I will take on this summers trip to Alaska to keep the phones & tablet charged to take that load off the RV’s batteries. A long term report will need to wait about 6 months but the prospects look very good. The quality and thought that went into the product is evident and worth the price. Their solar controller was flexible enough that I ordered a second one for use in another system I have.

55 Watt 12 Volt Monocrystalline The Dimensions of the panel is just about the size I needed to fit, 26 INCH X 19 INCH Having the flexibility and no sharp aluminum corners to gouge the dash is very nice. The Dimensions of the panel is better for removing out of the front windshield during driving I like that it will keep most of the sun and heat out of my truck. Off Roding in my 4×4, I can use the panel to get some more life out of the long trail rides, with heavy power use or just using more electronics’ at the camp ground. 55 Watt is good for the size of the panel, 4 grommets at the corner making it easy to mount. The connectors did not match my controller, I will need to get a pig tail. I will get some suction cups for mounting it using the 4 grommets.

Overall construction seems pretty good but the panel dropped down to 6.4w@13vdc after 3 months of intermittent use. Out of the box it tested at 65w@13vdc in full overhead sun at noon. I cannot find a way to contact the seller through Amazon and an internet search found a company with a similar name that stated “Alto Solar Inc. does NOT sell any products on Amazon. If the product you are inquiring about is not on our web-shop, it is not our product.” Seems like a common problem.
Update: The seller reached out and was able to refund the purchase.
