Renogy Flexible Solar Panel 100 Watt, 240° Ultra Flexible 100W Solar Panel 12 Volt for Marine RV Cabin Van Car Uneven Surfaces Off-Grid Essentials

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.

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…

Its weight makes it very versatile, even though I have never gotten over 125 watts in any condition, I still like it and now have 5 of them. I would recommend it, as that, very durable light 125 watt panel

Very low profile, I stuck to my pop up truck camper roof using 3 lengthwise strips of 1" 3m VHB (very high bond) tape using 3M 94 primer/activator and a strip of flashing tape across the leading edge to prevent possible wind lift. Hooked up to a Renogy 30 amp controller (room to add more if needed) and SLA deep cycle battery it works great. When you first connect it and see your battery voltage and the level of free power being generated its pretty cool! I camped off grid for 4 days and it kept my battery topped up so don't think I need any more. Note that 175 watts is on a perfect sunny day with the sun directly over the panel, with a flat mounted non directional panel and occasional obstructions etc, I still manage at least 100 watts. For each 100 watt panel you need approximately 10 amps of controller/charger. You need the 8 gauge wires with plugs on from Renogy that connect the panel to the controller and a pair of 8 gauge wires to connect the controller to the battery. This is an easy project for your average DIYer.

This is thin enough and light weight so that it will install easily on the top of my A-Frame trailer. I can mount it permanently and not worry about any damage, because it will be on the top surface, not in the way of any potential impacts. The waterproof junction boxes and all weather panel are perfect for keeping my LiFePO4 battery charged and refrigerator running properly while towing. Only problem was that Amazon did not deliver it on the Saturday that I chose under Amazon Day Delivery. It was delivered two days early, which caused a problem for me.

Bought two of these for my Sprinter Van. Happy with the performance. I got 250 to 300 watts on fully sunny days charging 800 Ah CHINS batteries. The reason is that if the batteries are nearly full, my Smart Victron MPPT will reduce the charging current and the observed wattage from solar PV reduced as well. I'm buying more to populate my boat (38' sailing Yacht). Love these panels it starts producing electricity from dawn to dusk. My house solid panels start to produce around 9-10 am.

Disappointed that they would place the connection and electric wires in top of the panel in direct sunlight. Also the didn't mark the positive and negative output wires. They also used black wire for both positive and negative. Sad

Paneel is niet zo flexibel als ze omschrijven. Het paneel moet echt met zorg worden bewogen tijdens de montage. Het haalt niet de 175 watt die men pretendeert. Al met al een redelijk product, fors aan de prijs. Ik heb er 1 koelkast van 60watt, via een 12v-230v omvormer, op staan. Werkt goed als er voldoende zon is, houdt dit paneel de koelkast goed bij.

Tengo dos placas en el techo de mi camper, me dan suciciente potencia para cargar mis baterías de 200Ah. Estoy muy contento con la compra.

UPDATE: I found out that the visible Amp in the display is how much it's sending to the battery, and not what the solar panels are delivering. This means that when it shows 10A, it's probably charging at 10x14V = 140 Watts. Today I got about 200 Watts of charging, but I have my doubts that the controller is accurate. I will report back after I got a good battery shunt. After all the horror reviews for cheaper brands on amazon with panels only delivering a fraction of what they promise I decided to go with Renogy. I ordered 2x175 watts panels for my van and they fit perfectly on the roof. While testing I was pleasantly surprised: * The panels easily deliver the advertised wattage * When the temperature is lower: like 10-15 degrees I sometimes even got up to 400 watts instead of the 350 max. * Even with low standing sun they deliver a decent amount of sun +/- 200 out of 350. * While overcast I still got some solar power. So far I had huge amounts of rain and hail already within 1 week, but they are holding up nicely.

I’ve just put this on my pop top camper 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.

Très bien. Installé derrière un régulateur mppt. Fourni l’amperage annoncé
