Flexible Solar Panel 100W 12V Monocrystalline Bendable - 100 Watt 12Volt Semi-Flexible Solar Panels Charger Off-Grid for RV Boat Cabin Van Car Uneven Surfaces

I have been testing it now for almost a year. The "special" surface does indeed improve the efficiency. My tests make me believe that at any sun angle more than 30 deg above the horizon, the panel puts out almost exactly the same power whether laid flat or raised up to direct line with the sun. I have other panels that clearly need to be tracking the sun to get full efficiency. I read a lot of reviews where the people claim they don't put out full rated power. Something to remember. The Solar controller is only going to produce enough to supply the load. I built a test rig with a a bunch of different LED bulbs of different wattages so I could put customize load on the system and watch to see when the load started taking power form the battery. On clear full sun days between 10:30 Am and about 2:30 pm I could reliably get 90-95 watts from the panel laying flat. If I had run the 75 ah AGM down to near inverter (11.5 volts) cutoff the night before, the panel would have it back to full charge by 11:30 or 12 o'clock. I have 2 more panels on order and the 3 will get put flat on the roof of a Ram Promaster van to provide day time power to a small fridge (1.3 amps 120 VAC max averaging about .75 amps AC over time) and still give me over 10 AMPS charge to my battery bank. I will try to remember to report back.

This product is durable, easy to use, portable, and well worth the price tag.

I bought 2 of these panels to explore how I might use these in a mobile, off-grid setup. I paired them with a Renogy Wanderer Li 30A 12V PWM, charging an ECI Power 12V 50Ah Lithium LiFePO4 battery.The panels appear to be well-built and durable. They also look quite nice as well.My issue with these panels is that I was not able to generate acceptable output amperage, where I was only able to get between 3.0 and 3.4 amps for each panel. I tested these panels side by side with my Newpowa 100 Watts 12 Volts Polycrystalline Solar Panel using the Renogy PWM. With all the panels at the same angle and using the same PWM, I was able to generate 5.6 amps of current (around 75 watts) with my NewPowa, but each of these panels were only generating about 3.2 amps (around 43 watts).Next, I connected these 2 panels in parallel, to compare them to my ALLPOWERS 200W Portable Solar Panel. The ALLPOWERS generated 126 watts with around 9.25 amps. These panels were only capable of generating 95 watts at around 6.9 to 7 amps.I am returning these panels for a refund, after benchmarking them for several days. It's a shame because I really like the build and the look of these panels, but at the end of the day I need the PV output to be higher.Based on the output of these panels, I can only give it 2 stars. If the output were just a bit better ( say 4.5 amps under the same test conditions used) I could have given 3 or 4 stars.

I can only get a max of 52 watts from this panel...they look very well built. Very sad!!!

I purchased 4 of these panels they have survived a cruising season so far around Florida and the Bahamas. However, these panels have never output over 63 watts each. They are parallel installed to the victron 100/50 controller (my 2nd controller) by 10awg tinned, soldered, marine shrink-wires. I've plugged each panel in one at a time... my main panels twin 330watt panels put out 345watts in the sane sun.

As background... I owned a solar electric business for 33 years and have installed around 400 off-grid systems. These modules are chosen for their light weight because we are aboard a high speed trimaran where gear taken aboard MUST be kept minimal and very light. She sails 300 mile days in cruising weight mode so if very agile.I recieved the modules shipped by the Amazon Wearhouse in the USA to New Zealand during Covid-times very quickly packaged in a box that was HUGE and could have held another 15 modules inside it (kind of stupid considering the international shipping costs). It was difficult to get Amazon to get our customs import number and TIE on the shipment.We are on a 40' Farrier F36/39 Trimaran that has sailed to New Zealand from the Pacific Northwest Canada. We are replacing failed HQST brand 100 watt flexible modules and forced to replace with almost exactly the same size module due to space and racking design. We carry 600 watts of PV permanently mounted and another 200 watts in modules that we store below and put out on deck (tied down) when the insolation is poor. ALL these flexible modules have relatively short lives, consider them 'disposable'! There is no brand that will last as well as a glass fronted and aluminum framed module. If you can aford the weight ALWAYS purchase Glass fronted Aluminum framed modules of high quality manufacture for sailing use.The best flexible modules for marine use are made by "SUNPOWER" get these if you must use flexible ones, when we departed on our circumnavigation, they were not yet available. We can't fit them now because they are a bit longer length.I will report back on this modules durability in a year or so.My only comments are that they are significantly shorter in Length than specified and also narrower. We can accommodate this but it may be a problem for others, they also weigh a bit more than specified, probably 30% heavier than the modules they replaced (@1.2 pounds more).I would NOT pull off that front sheet of plastic! If it's peeling you are kind of F@@@@ed. Some of the modules with smooth fronts and non ETFE front sheets use this to prevent scratches in shipping and it must be removed before use, these do not have this. The heavily textured fronts on this modules front sheet is interesting and I hope it holds up but my 'gut' tells me it is a weak point. Possibly a deal killer (we will see)

handy reserve

Delivery of parts not accordingly with the order. I got the 2 panels, but never received the charger and wires.Don’t know if it’s coming on separate parcels, but panels were received more than 2 weeks ago, and still no news about the missing parts.
