Newpowa 100W Flexible Solar Panel Portable Bendable 12 Volts 10BB Mono Cell for Uneven Surfaces Marine Camping Home Boat RV Surface Black

I bought 4 of these panels earlier than I needed for a camper I am building because of the black friday price that was too good to pass up. I set them up temporarily to test them and was very pleased to see on a full sun day the 4 panels peaked at 375 watts according to the charge controller I am using. What is important to understand is that I am in Minnesota and the shortest days of winter are happening right now. That is an impressive amount of power for winter sun here. I have been running them for 30 days now and they have performed great on what little sun we have gotten. I have had days of 100 watts from the 4 panels with overcast skies not a bit of blue sky in sight. They are connected to a bougerv 40 amp mppt controller and 2 100ah lifepo4 batteries. I have been using a pure 2000w sine wave power inverter to power tools building my camper. I don't know how long they will last, but time will tell. For the worst part of winter they have performed well. Can't wait for summer to see how well they do. For the small size, I expected less output, and maybe during summer they won't do any better due to the temp rise that will happen. I will be buying more as my project gets further to max out the roof area of this camper. Update, 9 February 2025. Have added 2 more panels as I had planned for a total of 600 watts for my RV project. February in Minnesota and my test setup of all 6 panels with winter sunshine has produced 539 watts. Today, I started breaking in 2 100ah Lifepo4 batteries that recommend 3 total charge discharge cycles. Started charging at 10:30 am at 0% charge and after 2 hours they are 50% charged. This time of year up here we only get about 4 hours of good charge time so panel performance is very important. I highly recommend these panels. The other thing I like about them is the small size compared to other 100 watt panels. It will be interesting to see how they perform once mounted on the RV as 2 will be on flat roof area and 4 at about 22 degrees. Fixed panels on an RV roof never see ideal angles to the sun so good performing panels are a must.

These are great solar panels and I really like that they are compact!.. I’m getting ready to put solar on my truck camper and I can fit one of these in between a roof vent and the AC.. A large one would not fit… I would recommend these to anyone!.. The sellers are very nice and if you have a question, they will respond quick! EDIT.. DO NOT Mix-Match panels! Mix-matching panels of different wattages and voltages is not allowed. If they are of the same wattage and voltage, it is recommended that you ask the customer service staff for confirmation before proceeding. Because the difference in parameters may not be apparent in a short time, but will appear after long-term use, which may affect the product performance and warranty. NewPowa’s technical team has been very helpful !.. They care for their customers explaining the dangers of mix-matching solar panels!... They are very nice and they answered every question I had and replied quickly to my messages instead of having to wait 2 days for a response!.. I will recommend NewPowa to anyone!

I am not a solar power expert by any means. I hooked this panel up along with a Bateria Power Intelligent Portable Solar Panel Controller To maintain the batteries in my quad and my side by side. It is actually hooked to three 12 Volt batteries and is working absolutely flawlessly so far. Even on cloudy days it takes the battery voltage up to 13.5 volts and overnight the batteries drop to normal range of 12.5 volts. This is exactly what I wanted it to do. Hopefully I won't be buying a battery every year because they don't make it through the winter now. This is by far the great value for a solar panel this size and strength. I do recommend it.

I’m not very experienced with solar panels, so take this review with a grain of salt. The size is very nice, it’s smaller than some of its competitors in its dimensions and fits on the roof of my Prius very nicely sideways so I could fit two of them up there if I wanted. The max output I’m getting is only 71 watts. I’m not sure if that is because it is so hot, but if the sun is high overhead it’s going to usually be hot. Maybe at a cooler higher altitude it would perform better? It would probably do better with better ventilation. Still, it seems to be enough for my use case. I only need about 0.5 kWh a day in the summer. Much less in the winter. Great for powering my portable fridge.

High power output. Almost "too" flexible, but I won't take off for that because they're supposed to be flexible. Well packaged.

Still producing well! I expected failure because of extreme environment, but wow, still strong. 4 x 100w flex panels glued n screwed on top of my van. Ice n snow in winter and 125f/51c in summer. 300w right now with dusty panels not direct sun.

Just installed, so far so good. Even though it's raining right now it is still pushing current into my solar roller. How fun is that. Edit: I've been using it for about 400 miles now and it's doing great. I get about 15-20 miles per day of charge. My commute is 10 miles total so it's plenty. I've used solar for different applications for a long time but this is by far the most exciting application so far. I mean, my gosh man. Low effort transportation that is fun and fuel/energy independent, not efficient, independant! It's like riding around with your own oil pump and refinery. Or your own corn crop and distillery. Or a horse that you never have to feed. You don't have to eat more food to offset the calories burned by riding a regular bike. It's not a tesla.. it's not a pickup truck.. but in the function of transporting your body to and from work and doing the weekly grocery shopping the requirements are fulfilled and you keep the daily wear and tear off of your larger vehicle. A single 100w solar panel does all of that!!!

Per il tempo che ho avuto modo di provarlo sembra un buon prodotto. Certo d'inverno con poco sole non si può pretendere, ma in momenti di luce abbastanza forte anche senza ricevere i raggi solari riusciva a mandare una leggera carica alla batteria.

Habe mittlerweile ein zweites 100 Watt-Modul angeschafft. Die beiden Module bringen (im Moment*) bei maximaler Sonneneinstrahlung einen gemessenen Wirkungsgrad von knapp 88 %. Das ist deutlich mehr als erwartet. *(Der Standort lag dabei Mitte Januar auf einem Breitengrad von 38° 20‘ 25“, die Module stehen fix in einem Winkel von ca. 25° an einer Hauswand. Die Luft ist sauber, die Paneele könnten bei optimaler Ausrichtung vlt. noch mehr bringen. Für meine Zwecke reicht es aber gut aus. Auch bei bedecktem Himmel liefern die Module noch erstaunliche 6 % an den Solarregler ab. Mein bisher verwendetes 180-Watt-Modul war etwas sperrig beim Transport und dort waren auch andere Zellen verbaut. Der Wirkungsgrad lag 2-3 % bei höchster Einstrahlung darunter, bei Schwachlicht mehr als 5 %.

Muy eficiente, rebasó mi expectativa.

Étonnant même par couche nuageuse bon rendement prochainement à commander pour plus d'autonomie

Te dice.... Fabricado en México, las células de importación y non-chinese celdas???? = Si fabricado en China !!!!!!!! pero bien echo, funcióna bien.
