Renogy 100 Watt 12 Volt Extremely Flexible Monocrystalline Solar Panel - ETFE Layer, Ultra Lightweight, Ultra Thin, up to 248 Degree Arc, for Motorhome, Caravan, Camper, Boats, Roofs, Uneven Surfaces

Genuinely capable of yielding the advertised 100W.It's robust and flexible. Slightly larger than expected - but an excellent product, small enough to be used as a portable solar panel.Some solar panels offering 100W and above have an open circuit output voltage that's slightly too high for smaller power banks (power banks around 300 Wh or less), so they trip out the power bank. But this gives you 100W without tripping out your power bank.You can connect to any power bank that has a DC 5.5mm input - just use an MC4 to DC 5.5mm converter cable.No voltage regulator needed! You just need the panel, your power bank and the convertor cable and then you can easily set it up anywhere.You can leave this outside, it's fully waterproof. (Your power bank obviously needs to be in a watertight and sunproof container if it's outside).I've tested lots of panels - and this offers the best balance of quality, power, portability, strength, flexibility with a low enough open circuit output voltage to be compatible with small or large portable power banks.Highly recommended, buy with confidence.

The edges need protection.A plastic or rubber seal to fit all the way around the panel. Cable ties for hanging up . I am going to ge a bag to carry it in .I think you should have extension solar cables 6-10 metres to add in line. + 2 pairs of solar connectors .

Have got this rigged up in our 1978 VW bay campervan. It fits across the inside of the windscreen perfectly so it doubles up as curtains! We just put the sun visors down to keep it in place.It's mega lightweight so we can move it around the van without issue. It keeps us and the tunes running for days and tops up the leisure batter a treat.Thoroughly recommend.

They're quoting short-circuit current as standard output.The actual stats are well down even in direct sunlight.They may be honestly quoting output that is possible if you're literally baking alive on the equator at 50Centigrade under sun that would cook and egg in your hand, it's hard to tell fact from fiction.The holes on the side of the panel are put on by guessing and are all over the place - if you want to anchor two of these panels side by side using the fixing holes from both adjacent panels on the same bolt lug then forget it. I tried and failed as they were 7mm out in both the X and Y axis.For your money there are much better panels on the market, anything from LG for example - as LG are 'defacto' for a lot of home installations.However, if you must have low drag coefficient and/or curved surface mounting, then they are not the worst, but perhaps think about doubling your power estimates. Their claims of the coating (basically little pseudo microlenses bonded on the surface in a sheet) achieving higher performance when the panel isn't directly pointing at the sun are optimistic at best. If you didn't have the beads, the panel would probably work better when actually pointing at the sun.22% efficient conversion rate? Nah. No way in my optinion. The top panels on the market struggle to get anywhere near that, so there is no way they have achieved that in this form-factor.While I don't have sceintific measurement devices, I did a side-by-side comparison with my friends RV who came and parked next to me. He has two 'solid' 200watt LG panels, which wiped the floor with 4 of these 100watt ones.I would recomend just install them in series to multiply the voltages, and let the MPPT convert 'any' input voltage * amps, to your desired charge current.I get around 80 volts * 2.5 amps from 4 of these in series (reported by the MPPT), which the MPPT steps down to 24 volts * 7-10amps, to charge my 24 battery. (Usually it's around 2-4 amps in all but the strongest sunlight).Most battery chargers will be 6-10 amps, so this is a reasonably comparable output to a modest automotie battery charger?Configuring these panels in parallel will just give the MPPT more work to do, but if you had full parallel configuration (requiring loads more (and much thicker) wire and connectors on your vehicle roof), you'd get perhaps get a peak of 10 amps into 20 volts on the input to the MPPT, which would probaly convert it to 8 amps * 24 volts (in my case anyway, so pointless). Only get if you need bendy panels and double you calculated estimates. This company are just 'a-another' shady Chinese vendor with a very plausable, but ultimately non-existent UK office.When I ordered the panel, I got slapped with $40 import tax on top of this already grossly overpriced 'amazon prime' delivery, so factor that into your cost-benefit calculation.

I’ve just put this on my pop topcamper but the positive cable is only about 4 inches long I don’t get why renogy would not put a longer cable so on a pop top you can feed underneath and easily connect cables underneath where it’s dry and better fot a wire connection. .very strange.

We have two of these mounted on our Bimini year round on our boat in the Med. We have them lashed using the eyelets and they’ve survived 50kts+ winds so the build quality is excellent. A little corrosion of the eyes but that’s the only evident wear. During summer we regularly see the panels produce the rated power of 100W on a cloudless day with midday sun. When these finally give up the ghost we’ll be investing in more. Amazing value and essential kit when cruising.

The output looks good (4.5A) on a sunny English day but why oh why is the positive cable only 6" long. Means I have to put a connection on top of the van whereas the negative can be extended inside the van where it's dry.

Bought this to replace a Photonics Universe one that had failed. Immediately noticed the far better quality. Puts a good charge into the leisure battery even in low sunlight cloudy conditions. Mounted directly onto campervan roof using Sikaflex keeps my 110 leisure battery topped up .....in recent hot sunny weather I had fridge running together with inverter running fans and panel was putting out 18-20 volts. Extremely impressed and with the guarantee you can buy in confidence. Will be my first choice for my next camper project. 5 STARS
