Renogy Flexible Solar Panel 175 Watt 12 Volt Monocrystalline

Korrektur:
Die Messung mit der Powerstation gibt vernnftigere Werte.
14:45 sonnig und klar/liegend gemessen.
P1. 58W. P2. 59W.
In Reihe 110W…das ist ok…der Kratzer scheint keinen Unterschied zu machen.

Offenbar hat der Victronregler o. das Solarkabel ein Problem.

1 Pt. Abzug wegen dem Kratzer.

Schnelle Lieferung, Verpackung i.o. Panel 1 hat deutliche Kratzer und wirkt staubig, Panel 2 einen kleinen. Keine Schutzfolie. Qualittskontrolle wo?

Diese Ergebnisse haben sich als falsch erwiesen. Ich lasse Sie aber aus Transparenzgrnden stehen. Vielleicht hilft es ja mal jemandem, der ein hnliches Problem hat.

Werde nochmals testen wenn die Powerstation da ist und gebe dann ein Update.

Just received the 175w panel, just did some quick test to make sure everything is working. Max watts I’ve seen so far is 135 watts charging my EB3A. The pack was almost charged so would like to test it again with it at a lower percentage. Also a slightly hazy day. Plan to run this panel on a van. Build quality seems good. The panel doesn’t like partial shade and watts drop off to around 15-20w.

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 .

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 CrimpingTool 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.

Bought these for emergency after-hurricane power and changed my mind to use them continuously. Super thin and light and I am getting very nearly 700W from 4 in series. Now just have to paint my flat roof and put them up there haha

I bought this to charge a solar generator and I thought should hold up better than the suitcase/folding panels they generally sell for that purpose. Laid flat on the ground (was trying it out on a windy day) I was getting 150watts of generation, really good considering my latitude and not leaning into the sun.

Eigentlich habe ich mir dieses Panel nur als “Notlsung” fr meine Bluetti EB70 gekauft, whrend ich auf die “richtigen” Panels warte. Die Bewertungen waren ja sehr “durchwachsen” und ich war mir ein wenig unsicher. Aber heute bei strahlendem Sonnenschein Mitte Mrz liefert das Panel grob ausgerichtet (d.h. auf dem Balkontisch ein wenig angewinkelt grob zur Sonne) 82 Watt Ladeleistung bei meiner Bluetti EB70. Finde ich gut und reicht erstmal aus. Allerdings glaube ich nicht, dass das Panel Bypass Dioden verbaut hat – die Leistung bricht bei leichter Abschattung doch ziemlich ein, daher nur 4 Sterne beim Preis-Leistungsverhltnis. Ist mir aber erstmal egal, werde das mal beobachten. Im Moment 5 Sterne, Lieferung war gewohnt schnell.

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.

Got this on sale and bonus, it works well even when it isn’t at the perfect angle to the sun. Great as a portable panel while camping in the shade.
We got ours in late 2020, the one we got is 48″ x 21.6″.

So I bought this 175watt panel to mount on the roof of my Tahoe. I read that flex panels aren’t as reliable as solid ones so I purposely got one that had more watts than I needed.

On an overcast day here in Cali I average between 15-50watts. On a sunny day the most I’ve gotten is 110watts. Please note that I just installed these in December of 2020 and haven’t used them in the summer/ spring yet and so far I’m happy with the performance.

I use it primarily to power my refrigerator and to recharge my devices.

I use solar to power a fridge in my work vehicle, my previous panels finally wore out. It was difficult to find replacements of suitable dimensions, until i found Renogy. The new ones were delivered promptly and as described. They have been installed now and they are working well. Happy customer.

Reasonably flexible with terminals on the upper surface allowing it to lie completely flat means that it is really easy to install and connect. Output was very effective, even under limited or man-made light source. the textured surface really does make a difference to light collection and utilisation.

I originally purchased a 200 watt Goal Zero briefcase but it is too bulky and heavy for me to use so I purchased 2 of the 100 watt Renogy flexible monocrystalline panels based on the good reviews here on Amazon. With the goal zero 200 watt briefcase, the most I got was 127 watts. The Renogy set gave 157 watts max (but that was with the MPPT charge controller) though they mostly hovered around the 140’s watt input which I think is pretty good. I tried just one panel plugged into the standard charger (without the MPPT charge controller) and it actually pulled 61 watts at one point but then dropped and hovered around 50-55 watts. This was about 4pm, Mid August, in Sunny San Diego. I’m happy with the purchase because they are so lightweight and they work pretty darn good so far on this first day trying it out in the backyard. The only thing I don’t understand is why Renogy made the positive cables so short. As they are, I cannot lay the panels side by side unless they are head to head on the short side of their rectangular shape. I will have to purchase some type of extension cable. Why in the world do they make them this way? I wonder if I will lose wattage after installing the extension cable. All in all, I am satisfied with this purchase and if they hold up over time, I will purchase again. Mine came with 3 grommets along each side of the panels, a total of 6 grommets on each panel.

Sturdy build even though they are flexible, bit more pricey than some other panels but worth the extra cost, they perform well in sunny conditions even when flat they are giving 70 to 80 watts.
Would recommend.
