146 reviews for 100 Watts 100W Solar Panel 12V – 18V Poly Off Grid Battery Charger for RV

  1. Glen Fournier

    I’m using the panel to keep my house batteries in my van topped off. It does a great job for the money!

  2. Paul B

    They seem OK if a little flimsy. But I think they are solid enough once they are mounted, which is all that really matters. You won’t get anything close to 100 watts out of them. It’s slightly hazy and I’m seeing 62. I’ll edit the review if it goes above 70 but I doubt it will. As long as you know you are buying a 70 watt panel then you’ll be happy but I gave three stars to penalize them for lying.

  3. LJLJ

    I just got around to installing these panels in parallel for a 400w systems charging 3 – 12v batteries (127 ah). The panels were in storage for several months. Only took a couple hours to bring batteries up to full. I recommend these panels for a small solar generator system.

  5. joshua Roush

    Works great

  6. Debbie Mays

    Good quality for money

  7. Kendall Kelly

    I love the panels would like to order more but for some reason you have been out for over a month do I need to look elsewhere or will you be getting the issue fixed

  8. sandy cooper

    It works all right

  9. Thomas R.

    I use these to charge my solar power stations during power outages. Later on I want to install my own solar system and will be buying more of these as I can afford to until I reach the wattage output I need. The extremely high price of batteries is the only thing preventing me from having a system to power air conditioning at this point. I can afford these panels though even if I have to buy one each month. They put out 98 to 102 watts in full sun!

  10. Bob

    2 panels– Controller said 15.5 and keeps battierys at 14.4 until dark 2 – 6 v. Deep cell and 1 -12v deep cell used 12v light s all night. tv ECT never ran out of power for a week at beach . Great I would buy again

  11. Web Customer

    For a backup system and easy to install…

  12. J R BURDEN

    It’s everything I expected and wanted!

  13. Isaac Truelson

    Waiting for return, will update.

  14. Robin L Crosby

    Works well for what we needed it for!

    12v battery charger

  16. Tuell

    Good for off grid living or hunting shack. Use heavy gauge wire for best results and performance. I got 4,excellent price.

  17. Joseph Richburg

    still working

  18. shan bailey

    Everything was perfect. I have purchased 15of them no issues that’s why I keep buying them

  19. Jonathan Mortenson

    Perfect for my needs. Great price

  20. Web Customer

    Awesome panels well made and a good price

  21. Rivermark

    It actually charge my golf cart batteries when the other ones did not

  22. Dennis

    Works well. Have 3 of them. Usually about 3a of current

  23. Abigail Lee

    I received the solar panel as a gift, and mounted it on top of my shed to bring in some power. I find that it generates a good amount of electricity to charge up the various solar generators that I keep around the house for back up any emergencies. On a bright day at around noon I can get about 60 whites at the peak when using this. I think that is pretty good since no panel is ever going to reach 100% of the rated output. Looking at the pricing, I think it’s very reasonable and it does the job well. I think there are definitely fancy your panels out there but this one gets the job done just fine I received the solar panel as a gift, and mounted it on top of my shed to bring in some power. I find that it generates a good amount of electricity to charge up the various solar generators that I keep around the house for back up any emergencies. On a bright day at around noon I can get about 60 once at the peak when using this. I think that is pretty good since no panel is ever going to reach 100% of the rate it I’ll put. Looking at the pricing, I think it’s very reasonable and it does the job well. I think there are definitely fancier panels out there but this one gets the job done just fine. It does not include any mounting hardware, but it is pretty easy to mount on wood since there are holes in the bottom of the panel or you can also buy L brackets to mount it. Cable length is just fine for most applications

  24. S. Tracy

    I first purchased 150 w panels so decided to purchase some of these as well. They perform awesome. With the right atmosphere they actually over perform. Will definitely purchase more.

  25. Dalbert E. Bailey

    These are quite impressively sturdy and well made, they came shipped in containers which were very sturdy and no damage was found. However, I cannot state their power or ease of setup. I didnt notice that they are in a solid aluminum frame and had thought they were flexible. I’ll try to sell them later, or use them somehow. Still, a good purchase value in all regards.

  26. PRIME SHOPPER in the USA

    100 watts of Sun… Great Product, Very Happy with Shipping. Very happy

  27. Frank D.

    Worked as stated

  28. Gary Nelson

    I put one on the top of my Bronco. It’s on the rack in top. I have two refrigerate running off it . We go out camping and in the back country. It keeps everything up to change. We run lights and all kind of things at night. As long as the sun shines my system stays changed

  29. Smiths

    Works great. Replaced a flexible panel that twice failed (once from hail once possibly from a branch strike). This panel has been hit by many a low hanging branch and still no cracks or scratcher or change in performance after a year. Very happy with it.

  30. Web Customer

    The price is best I could find for a product that works great. Have 4 of these powering my off grid party palace.

  31. kerry johnston

    Love it

  32. Scott Winterringer

    These panels are a fantastic bang for buck. However something to note. There are two different sizes being sold under this item. One has the branding on the front and is larger than the new? Smaller panels. There is a energy difference that is noticable.

  33. Richard295

    I have 4 of these solar panels mounted on 2 poles. They feed a Victron MPPT controller into AGM batteries. The level of performance they provide for the price is without equal.

  34. Robert Young

    Needed to replace my 18 year old panel since it was barely charging a new marine battery over a full day of sun. This unit has the battery charged by mid-morning on cloudy, rainy days. Solid frame, came with pre-installed MC4 cables, had it up and running 10 minutes after it was delivered. Very satisfied with this unit.

  35. Web Customer

    The panels produce 22.4 volts and 5.3 amps in full sun. This is what I wanted and at a lower cost than many of the other types of solar panels cost.

  36. The Electrician

    1 of the 4 I ordered was slightly bent.. Probably from shipping.. It wasn’t enough to crack the glass although it is a visible bow in the frame.. It doesn’t effect power output so I kept it.. Not sure how to make a product bulletproof enough to survive the monkey attacks that shipment puts on them but so far everything is working good

  37. Desmond Bradley

    Arrived as expected.

  38. Kent

    Was very impressed with construction quality and how fast it was shipped. 1/3 of the time it took to get connectors and wires.

  39. James C.

    Haven’t used it so far except for a test but appears to be well constructed.

  40. SERGIO TARRAGO

    Excellent product!

  41. Jeffrey Karrow

    Great price. I set the horizontal axis of rotation manually by observing the watts it output. Found you don’t need to rotate the vertical axis. I’m pulling in at least 52 watts at 10 am in Georgia in early April even with the morning sun at an oblique angle. I can’t measure the total output yet until I get a meter, but I can charge two 330 watt Zoombros batteries in one day. Last night the power went off in a storm, but not mine! Did not have to fumble for a flashlight. Panels are light, strong, and clean.

  42. Jake

    I am buying more of these soon!

  43. Ficht Etienne

    No problem

  44. Review4You

    After buying 10 of them, you average 1 in 10 is a dud, not worth it totally and the company is a bit evasive. Typical of drop shippers. They are as all now, overrated and false claimed, thats the new China Math in watts, actual is 72 to 75 watts with the best MPPT controllers. But all of these cheap panels are that, CHEAP!

  45. Jezabel Negron

    Me gusto mucho

  46. Mark Browning

    Great product!

  47. Woody

    Works great for charging my homemade power generator.

  48. Deanna Rice

    My diode broke today but until now has worked great

  49. Richard J. Grant

    Easy to set up, plug in leads, connect to charge controller that is already connected to the battery and done.

  50. Steven V.

    So 1st thing, I am personally new to the whole solar energy game, 1st thing I noticed is you NEED to buy the wires to connect to the plugs on the back of the solar panel, to connect to your controller. I had asked the question if you needed something like this to connect it before I bought it, but none responded to me so, I found out the hard way. The wires are not expensive but you do NEED them. Other than that is was in great shape when I opened the box. It had no cracks and was not broken in any way. I was a little surprised that the packaging wasn’t alot more secure from the manufacturer. Seems to me something made of glass would have ALOT of protection around it. But as I said it was in great shape when I opened it. But I did see in a couple of the other reviews, that people had received them broken.

  51. PJB

    Am novice and at a remote place, takes a month to get physical mail or freight Ordered some more wires we will see

  52. Kenny M.

    Works great

  53. William D.

    The workman ship was not of the best quality.

  54. CH

    We made a portable stand for solar panels with long cord so we can move it where the sun is. Works great!

  55. Web Customer

    Excellent value. Used to power a remote irrigation system

  56. Web Customer

    The mounting of it, doesn’t come with a stand.

  57. Pam

    These panels were the right size for me to lift and mount above my head. If they were and bigger or heavier It would have been tough to handle. Also the supplied mc4 conector wire were long enough that I was able to series connect pairs of panels to the parallel connect with 8 wire connector with no extentions needed. I then ran a red and black wire to my batter/controler/inverter cabinet. For mounting, the holes on the aluminum frame were uniform so that made mounting go fast. If you are doing big system you might want bigger panels. Well made and I am quite haply with these.

  58. Charles Brothers

    I installed this panel on the roof of my high top Astrovan. Its been working great. I’ve seen 75 watts so far and I’m happy with that. Be aware it comes with no mounting hardware what so ever and you will need to buy or fabricate mounting brackets. I bought those z brackets and used the additional set as a back up washer to get a good grip around the mounting holes. I used #14 x 1/2 inch screws to get a good bite into the fiberglass roof.

  59. Tri

    Works real well for me to keep the fridge running with 5 panels for the last 5 weeks. Will buy more

  60. Perry Hornkohl

    It did not come ready to use. I have tried contacting seller. Willing to buy what I need to use this properly. Oh well I’ll find out eventually

  61. acemike

    Works great

  62. richard

    appears to be a quality product . I would recommend this company.

  63. J. Ellington

    Bought this for my shed and with the exception of just having one of the MC4 connectors literally fell off, its been a good panel. Turns out the negative wire to MC4 connector was barely an 1/8 of an inch long and not properly crimped. Will have to replace it but other than that I like it. No damage what so ever to the package when I received it. More than enough voltage and amps to keep my 2 deep cycle batteries charged while running my fountain during the day and low voltage lighting at night.

  64. Mekidbrat

    When it starts getting anytime of light it start produce power even if it’s at one tenth of an amp

  65. mitch chapman

    ????????????☉☉

  66. chrisgreenwx

    What a great solar panel for the price. I am up to 5 and not even close to done. Wish I would have bought all these.

  67. RH

    Great quality of construction, meets or exceeds all specifications, price is great. Why pay more for a panel that was most likely manufactured by the same factory. Beware of reviewers that have little to no electrical background or have never worked with pv’s.

  68. Web Customer

    Have not used yet as panels don’t connect to each other with out buying more stuff, y-splitter to hook panels together. No brackets to mount panels . More money spent, had to wait to complete job. Next time I will look for panels that come with everything needed. Time is money,

  69. Web Customer

    Seems fine. Took a reading and it was up to specs. Time will tell…

  70. Vicente A. Rivera

    Exellent.

  74. George Rivera

    Great system. Keeps my boat batteries charged all the time.

  75. Lynn

    I can get more solor power, but it never gets up to a hundred watts on my battery, I have 2 30w and they never get to 30 either. I have a Goal Zero and had to buy a cord to connect this panel to my Goal Zero battery.

  76. Trey

    Would by again

  77. Kindle Customer

    Easy to use product, good quality. Arrived on time and in good condition.

  78. Liyanid

    Son buenas resistentes y duraderas llevan unos 3 menes en mi azotea y han cumplido con su labor. Vendré a compras mas.

  79. P. Mullin

    Installed on our shed to charge a battery used for lighting. Works very well. Good weight to it and easily installed.

  80. Angie Loving

    Awesome

  81. jumpingrantflash

    It’s a nice unit and works well I just didn’t like that there’s no stand or folding legs or anything. We used it to charge our camper battery and it worked well with minimal sun on our camp site. Know that you need special tools to wire the clips that you’ll need to plug this thing in.

  82. Sam

    I purchased four of these and added them to a 200 amp hour system. I live in Alaska so the sun right now (June) is up about 18 hours a day so I do have a bit of an advantage. However, we get a considerable amount of cloudy days and when we do we get very thick cloud cover. I have been really happy with all of my results this far. The advertised amperage is accurate and so far the durability seems to be good. If all goes well this winter and they survive the -30 temperatures and 3 hours of sunlight a day will likely double my system. If you are looking for a good solid panel and are not needing to use as little space as possible this is what you want. UPDATE*** Still all of the original panels working and I am getting more every month to add to the system. No failures all positive for me!

  83. gordon b

    good solar I will by more

  84. jwins

    I have bought two of these and they work great for our camper.

  89. Bobby L Brady

    Great solar panel

  90. tbonetone

    Works good. Packaging could have been better. Puts out 22v at noon. Would have given 5 stars for better packaging. Will order more later.

  91. Sue P.

    I am now off the grid with these panels.

  92. David

    I have 4 of these now, i plan on adding more. Great panels!

  93. Orlando Ayuso

    I bought this solar panel for my Parents in P.R. And they are using for last 5 months and work very well!!

  94. Joel

    Pretty nice. Fit perfect on my Dodge Grand Caravan. Would give 5 stars but both of my panels had banged up and damaged corners. Worked great when I got them and a month into use, working great still.

  95. Deshawn

    Very nice design. Will be installing them hopefully tomorrow it’s snowing today!

  96. Dave J

    A most reasonable cost for the watts, and reasonable efficiency.

  97. iansingh

    Good very good

  98. Frankie Beech

    These work great. No problems. Light Weight and sturdy.

  99. NOE CABRERA TORRES

    Excelente product

  100. john

    Hard to see how good it works since its been snowing and cloudy since I got the panel. It still makes energy when cloudy. Im still in planning stage of how and where it will be placed.

  101. Inductive Soul

    The solar panel seems to work fine, but it came with minor scratches on the glass & a little bent frame… shipping material could be better I was disappointed in how this solar panel was shipped as I am fairly confident that, that is the reason for the scratched and bent frame. Aside from that its seems to be a good 100W panel, I have not tested its amperage output but it seems to work fine with my 30A solar charge controller hooked up to a 12V deep cycle battery, and is charging the battery back up after I boiled some water for some tea with an inverter.

  102. Ant Farmer

    Not very different from the 100w HQST and Renology panels I installed previously, except that the packaging of the Mighty Max was substandard. Box arrived with holes in it, glass not protected by a foam sheet, corner foam things were thin and damaged in transport, aluminum frame was bent in two places. The panel was okay, but the way they packaged this was irresponsible and just plain dumb. I bought this brand because it was a few bucks cheaper than the others, but whatever I saved was wasted by the disappointment of having bent up frames. The frame size was about a quarter inch or so bigger than the other panels, so visually it sticks out a bit in an annoying way. Output seemed similar to the other 100w panels.

  103. VALERIE GREEN

    100 Watt 12-18v solar panel: The panel arrived quickly, but there was an obvious penetration to the packaging. Upon opening the package, I discovered a pretty significant dent in the aluminum panel. No cracks in the glass or cells, but I was concerned. I needed this panel for the weekend. I tested it quickly with my meter and it appeared fully functional. After setting it up, it was charging my battery bank and working great! So, I can tell you that these are some tough panels, this one took a beating and still performed. Yes I wish it was not dented, but that is really the delivery carrier’s fault, as the panel was packaged very well. Very happy with seller!

  104. dkeener

    I was skeptical at first when buying a solar panel with a name that sounds like what a 3 year old will play with along with his tonka trucks… But sometimes you gotta risk it to get the biscuit. So I bought it. After installing it, and testing it I was impressed to say the least. Impressive output. It does what the label says. I have since bought more of these panels, and have recommended to other people. So quit reading and click Add to cart. Join the Mighty Max club. You wont be disappointed.

  105. Butch Wells

    Works ok. Will buy more.

  106. John

  112. coldcoffee

    Sturdy construction. Installed in my RV with a Renogy 30A charge controller. Even in this cloudy winter sun it is keeping the battery charged with the gas heater running all day. Can’t wait to see what it can do in the high country south of the Grand Canyon this summer.

  113. Customer1029

    At first I was a little skeptical about this panel, but after having it hooked up for four days, I can safely say that the description is accurate. On an average day it usually puts out a little over 6 amps, on a cloudy one I can get around 2. Overall i’m pretty satisfied with this purchase as this is one of the few panels iv’e seen that cost only a dollar a watt, versus most others that are $1.30-1.60 per watt.

  114. mrs042515

    Produces PLENTY of power for my outdoor movie theater! I’d highly recommend!

  115. M

    I love this panel this is the third one I buy came in handy after hurricane Maria hit us hard in PR. This panel give me and my family the energy to power up the house ( lights, fans, celphone, laptop,etc. for these past 3 month

    WOW getting 5.5 amps with winter sun ….. gotta be careful though cause I almost blew out a 185 watt Li-on solar storage battery …. too much amps for it.

  122. K. Roach

    coming down in price. can’t have enough solar panels when living off the grid; use why less fossil fuel.

  128. richard como

    It’s working out very well

  129. Mike Johnston

    Works great and to specs. The frame has warped slightly after about 3 months but I don’t see any change in performance.

  130. Bill W.

    It’s only been installed 3 days but appears to be working just fine. Make sure to get the mounting brackets and special connectors before going to hook everything up.

  131. Mr.FixItTop Contributor: Camping

    Good solar panel for the money! I easily get over 5 amps out of it and it’s still winter, I can’t wait to see what it puts out in the summer. Unit is well made, durable aluminum frame and nice glass that has already survived a pea sized hail storm. About the only gripe I have is that the unit was packed in very thin packing and the frame had 2 small dents in it. These luckily didn’t affect its operations and I always seal my panels w/ silicone so no big deal. I just wish they use more packing so they arrive in good shape. All in all, well worth the money.

  132. Manuel Gutierrez

    This is a ul listed 100 watt 12v solar panel works great !

  135. Space Design Warehouse Youtube Channel

    I was a little nervous because I didnt recognize the brand, and I’m pairing a couple of these with a few Renogy 100w panels, but now I have a sneaking suspicion that maybe they all come from the same place. It puts out the same 18ish volts, and married to my system with no problems whatsoever. Im extremely happy.

  136. william a.

    Panels work great but they are 18.2 volts not 12 volts like stated.

  137. jeff1965

  138. G. Cash

    Seems to be working fine and a very good deal for the money.

  139. LAH

    Nice price for this well constructed, the 100 Watt is under perfect conditions. normal December sunlight testing gave a max estimated of 92Watts so not too shabby for the price. Now I just need 19 more…

  140. Ron

    Works great, intact I love it so much I have already ordered 2 more! Unfortunately after running it for a week now I think I could have gotten by with only ordering one more, but I’m sure I will find a use for the 3 one somewhere.
