Newpowa 100W 12V Monocrystalline Solar Panel - Classic Compact Design, High Efficiency Module for RV, Marine, Boat, Off Grid (100W / Mounts)

I love the smaller size 100w mono cryst panel, I mean brilliant in compact size & still get 75-80w you get from the larger panel! I scored! You could truly ad them almost anywhere, for my Alpenlite camper it's just PERFECT! Fits perfectly on the sloping cap of camper the (newpowa) brackets are so well made snug clean connection, & nice height to keep them cool & they are secured to full alum frame, & nice all weather waterproof clips! getting 74-80w in full sun cool day60-70f, hot day 82-90f THE SAME! That's the brackets, they are designed for 'their' panels with real engineering smarts, highly recommend their brackets! So 6 months in all is perfection, I'm using Rich solar 20amp mppt ( I had store credit with them) & I use their portables b 4 I got my roof panel on, Rich black glass mono cryst100 watt portables, case with controller & wires another excellent score! 6 months & no change but an increase in watts after 2 months! That's another good sign of a good panel, Newpowa has also increased after the 1st 3 weeks in exact temps & sun, so I have an exact measurement another great thing about California, same weather same temps this time of year over several weeks. Yes Newpowa are fully worth it, I do know '6 gun 12 volt' out of Sparks uses newpowa as of this past year & they recommend so you can't get a better recom. All the best & happy trails to ya all! ****UPDATE AFTER 5BB & NOW 9BB small panels. Both panels at about 60w cool winter day Feb in Calif, so of course I'm disappointed all panels drop off after 6 months it's quit a pisser since I have my new PQ lithium batts 100A 12v LifPo & now 2 panels it's enough for my camper but damn I sure wish panels were so well made they would hold power for years as Home panels do, maybe thats the answer ..SOMEONE MAKE HIGH QUALITY HOME PANELS FOR RV'S! We will pay the extra$$ if it means we don't have to have that lousy feeling of (how much more are they gonna drop?)

I have purchased 1, 100 watt compact 5 buss bar, and 16 of the compact 9 BB and they all perform about the same. For the price, size, and weight they are great. As soon as it's light they start producing and during peak sunlight they'll occasionally make 80 watts. I haven't seen 100 watts like some people claim, but I can tell you if you multiply hours of peak sunlight (4 to 6 hours) times total rated wattage, you will have an accurate idea of what you will produce for the day. So my little 100 watt, 10 amp PWM controller system makes around 600 watts per day in the summer and my 16 panel system makes around 9600 watts/day in the summer. I have ran 7, 100 watt panels in series for around 105 volts at 5 amps, but as soon as I added an eighth, the voltage went up to over 150 volts, so I could not run it on my Bluetti AC 200 max. I currently am running 2 strings of 6 on my 900 watt input and 2 strings of 2 on my 500 watt input without any problems.Update: I don't know why I'm listed as a Vine Voice on this - I have not received anything free. I am up to 28 of the 9 BB 100 watt panels, and still love them. Going larger would have been cheaper, but I don't like to wrestle with things and these panels work. I have received broken panels, and panels without the diodes connected, and the company immediately sent replacement panels. I have 3 small systems and will eventually have something much larger. These are affordable and light, and the delivery is free, so if you are like me and wanted to slowly learn and build, they are great.

I will have to spend another $19.95 for extension cord.

Heavy solid construction producing power claimed in bright sun.

I bought this to power my 12 volts devices and I'm really satisfied with the performance. When I first installed it my battery was almost full so the charge controller was not pulling as much power from it, I was getting 90 watts peak power. Then next morning my battery was at 20% SOC, then I saw this panel power peak to 107 watts with 6.1 amps. If your system (load/battery) do not need 100 watts or more your charge controller would not pull 100 watts and you my think the panel is not performing as it should. Even on a cloudy day it reached 106 watts. I'm ordering 7 more of these, 1 more for my '12 volt devices' system and 6 for my larger "main" system.Components Used:- 40 Feet 10AWG Solar Extension Cable- 100 Volts / 20 Amps Solar Charge Controller- 12V 50Ah Lithium LiFePO4 Battery

Great for the price. Check the dimensions before you buy a panel. I was surprised how big they were.Measured it at 20v and 4amps in direct sunlight. Keep in mind that the device you are charging may not be able to take 80w. Mine maxes out at 57 through the DC input. At first I thought it was the panel until I measured it with a multimeter.

I've purchased several Newpowa panels in the past and have been quite satisfied. However, these "compact" 100W panels do not live up to their rating. Sure, they are smaller and lighter than their other 100W panels but the price you pay is output. In direct overhead sunlight on a clear day I have gotten a max of 72W out of these panels. Needless to say, that's a far cry from the 100W rating. When it comes to solar panels, size does matter and there's no free lunch. With current technology, you need the square inches to get the power and these just don't have it.If you need 75W panels to fit into a tight space, these are for you. If you need 100W panels, get something else.

Purchased 4 and installed them in series as an addition to our existing Newpowa panels on our sailboat. Just as the others did, they perform better than expected. With the 800 watt array and now this 400 watt array we routinely get 1300 watts during best conditions. We could not be happier with panels that produce more power than advertised!
