Renogy Solar Panel 100W 12V Lightweight Semi Flexible Black Division Monocrystalline Bendable Mono Off-Grid Charger Bundle | With 10Ft Extension Cables

It quickly became clear to me that reviewing a solar panel is more involved than reviewing a toaster! I have a "decent" basic knowledge of electricity, but I must say I've learned a LOT more since purchasing my four 175 watt (@ 20 volts, 9 amps each) Renogy Solar Panels for my Promaster Van.1) Order "Must Have" Items to attach to van/RV roof without drilling holes and allow future removal :Eternabond 3"×50" 1 roll - use sparingly.Velcro,15' x 2" Industrial Self Sticking, 1 box per panel. See pictures. OK, You will probably need to drill ONE necessary hole to bring the final two cables to the inside- also get an entry gland for that. The Velcro should be attached in strips on the raised roof ridges. Renogy says an insulated layer is unnecessary. After 3 months of searing heat, and some rain, all four panels are still secure.2) Purchase the max wattage, and max # of Panels that will fit up on your van/RV roof. Get the BEST and as MANY Solar Panels (and MC4 connectors, cable, and Y branch adapter) you can afford- you don't want to regret your buying decision on every future road trip, especially after all your work installing these panels. A good crimper like the WISS Solar PV Cable Crimping Tool will help a lot. Incidentally, Renogy has EXCELLENT Customer Support. Contact them with ANY questions.3) Install an EVEN NUMBER of panels, so you can connect your setup in a "series and parallel combination"(Google that to view examples). Per Renogy, they should all be of equal size/power.4) With 4 175 watt panels, I put 1 pair in series, I put the other pair also in series, then I put these two sets of pairs in parallel, so I now had a series parallel COMBINATION that yields 40 volts @ 700 watts, but only 17 amps, going to the Yeti or charge controller. Always Remember, WAV: Watts=Amps x Volts. (My 3000X Yeti will allow a max of 50 volts and about 1000 watts of charge). If you put ALL 4 of your 175 watt panels in parallel, you'll have an output of only 20 volts and 37 amps, and your panels won't start to charge your batteries until direct sunlight hits them. The high amperage will also cause your cables to get very hot. If you use the series AND parallel combination, you'll get 40 volts and only 17 amps, which means you can use smaller wiring (10 gauge) that won't overheat. You will also see charging as soon as daylight starts until dusk. You'll achieve the SAME charge rate of rated watts either way! Speaking of advertised panel wattage claims, you'll find that the time of year, where you are parked, air quality (smog/haze), and of course, time of day, WILL AFFECT the rate of charge. Don't panic if you don't get the listed wattage, it's a fact of life! Realistically, expect about 80% of the listed watts rating, on average. It definitely helps to keep them clean. Hose off and squeegee them after it rains. The dust does not disappear after rainstorms, but instead makes a muddy layer up there. Do not get hung up on "positive" and "negative" ends when you build your 'array' of panels, just have your multimeter with you the whole time and make sure you correctly identify the positive and negative final ends that are connected to the batteries.5) If your Van/RV has 6 or 8 little T posts on the roof, you'll get a LOT of peace of mind attaching each panel to the posts. Use some 1/16" wire rope cables to connect to a grommet anywhere on the panels parameters that you can. After driving around with these 4 Renogy Flexible Solar Panels on my Promaster for 2 months +, I am very happy overall. Their super thin, light design makes them ideal for zero wind drag, and they are absolutely INVISIBLE from ground level. They are a solidly built and well performing panel, and I am glad I made the investment to get the best Solar Panels available.

The panels perform well seem durable and are flexible. I’m very pleased with them. They fit the bill for my application. Small amounts of shade do not seem to significantly impact the panels’ output, unlike some i’ve used.I needed low-profile flexible panels to fit on my truck’s topper, between the roof racks. The size of the panels are a perfect fit, and allow 2 to be installed on my roof. I wanted the installation to be easily removable, but to also easily handle highway speeds without me worrying about panels flying off. Utilizing the grommets on the panels allowed me to use M6 tee nuts and M6 machine screws and 1” M6 threaded plastic knobs to hold the panels in place. The grommet placement on the 2 panels I received were identical. I fit the machine screws through holes drilled in the topper. The screws (and large washers) are on the inside of the topper, with the tee nuts on the outside. The screws and nuts are snugly tightened, which allows the plastic knobs to be loosened and tightened without someone inside the topper holding a screwdriver to keep the screws from loosening. I used RTV to seal the holes, which also helps hold the screws and nuts in place without turning. I’ve used similar combos on truck toppers for 30+ years and have never had water leaks. I also attached heavy duty velcro around the edges of the panels, and attached velcro to the topper. The velcro alone holds the panels very well, but I wanted more security for highway speeds, hence the tee nuts and machine screws. I also put a “carbon fiber” looking vinyl wrap on the topper where the panels fit, for abrasion protection. Insulation can be placed under the panels to insulate the topper from the panels, which can get hot. 5 mm foam insulation is what I use.

I mounted it on the roof of our Nissan Xterra - found it very easy to mount (with magnets) and I’ve been happy with output. Had it for three years and even though it gets its share of abuse (dust, sand, etc) it’s held up perfectly

Since I don't have any other solar panel to compare it to, I cannot give it a 5 star rating. It has performed without incident since I purchased it. It gives a sustainable trickle charge to my battery bank. It is not big enough to fully charge my bank with heavy use but on a full sun day it is very good in sustaining power.

The Renogy Flexible Solar Panel is an excellent option for anyone who needs a reliable, flexible solar panel for off-grid use. I purchased this panel for my RV, and I have been extremely impressed with its performance. The monocrystalline semi-flexible design allows it to be easily installed on uneven surfaces, and the 50 watt output is more than enough to power all of my devices. The panel is also lightweight and durable, which makes it easy to transport and use in a variety of different settings. I love that it's designed specifically for marine, RV, cabin, van, and car use, which means that it's perfectly suited to my needs. Overall, I would highly recommend the Renogy Flexible Solar Panel to anyone who needs a reliable and efficient power source for off-grid use. It's an excellent investment that will pay off in the long run.

Installed on a sailboat with a Victron controller. Very easy to install, and the Victron App is excellent. Purchases 2 of the 175 watt panels, which fit perfectly on the foredeck of our Grand Soleil 44. They are lightweight and flexible. When anchored, we are getting 20 amps to our batteries, at full sunlight. On a cloudy afternoon, we are still getting 10 to 20 amps. Our 5, 95 amp batteries are at fully charged in just a few hours. We are delivering power to a wine chiller, a refrigerator/freezer, a microwave, lights, and all the phones and devices. These panels are perfect for cruising. However, need to run the engine for hot water (30 minutes). Looking at electric water heaters…

It worked great. On a sunny day I was pulling in 2.2 amps. I use this for charging my portable charger and phone and it works well! I just wish the positive cord was longer.

Die Lieferung erfolgte in einer recht großen und flachen Kartonage. Im Lieferumfang befinden sich das Solarpanel und eine Anleitung. Wir haben zwei Mal die Variante mit 50W gekauft.Das monokristalline und biegsame Panel hat eine Maximalleistung von 50W. Wir nutzen beide Panels in einer Reihenschaltung auf dem Vordach unseres Hauses. Uns waren die Abmessungen und das geringe Gewicht besonders wichtig. Etwas merkwürdig ist die Tatsache, dass wir zwei ähnliche, aber eben nicht identische Panels erhalten haben. Die Leistungsangaben sind identisch, aber die Abmessungen und das Gewicht unterscheiden sich geringfügig. Ein Panel ist rund 5cm breiter, 3cm kürzer und 0,05kg leichter. Das ist für uns ok, da man die Panels auf dem Vordach nicht sieht, aber so etwas sollte grundsätzlich nicht vorkommen.Das Anschlussterminal sitzt auf der Oberseite und verfügt über MC4 Steckverbindungen. Die Kabel sitzen links und rechts. Wer die Panels, so wie wir, nicht verklebt, kann die Befestigungsösen in den Ecken nutzen. Wir betreiben beide 50W Panel an einem Hoymiles Wechselrichter. An einem sehr sonnigen Tag Anfang Mai haben wir bei nahezu horizontaler Montage Werte um 80W erreicht. Das liegt unterhalb der Leistungsangabe, ist aber zu einem sehr hohen Grad der fehlenden Ausrichtung/Aufstellung zur Sonne geschuldet.Die Verarbeitung der Panels ist gut. Die Herstellung erfolgte in China.In Summe ein kompaktes und funktionales Solarpanel.

We hebben 2 panelen extra gelegd op onze camper. Deze paste perfect op de bestaande installatie.

Great product but just bare in mind - any solar energy is seriously diminished when you put the panel behind glass.
