I picked up these 4 - 100w panels for about $50.00 each on a Black Friday deal, thinking they would make a nice addition to my Express van camper. They shipped quickly, but only 2 of the 4 arrived initially, the 2 went back, and the 4 finally arrived. I tested each panel, one at a time, connecting them to my Delta 2 while on my balcony. I was looking for consistent performance from each panel, and how they would perform, flat versus tilted, in So Cal on a sunny December day. The panels each delivered 20 - 30 watts flat, and about 35-45 watts tilted around 30 degrees. Performance was about what I expected and reinforced my plans to incorporate some kind of tilt mechanism when mounted on my vans roof. Then while fiddling with a panel, a gust of wind caught it, I lost my grip, and watched my panel crash to the ground, fortunately it hit on a corner and stuck into the sod. After rinsing it off, inspecting for damage, finding nothing visible, I tested it out again and was surprised to find it working just fine. These things are well built. It is now 2 months later, they are mounted on the roof of my van, with my homemade tilt mount mechanism, and the days are getting longer. The panels are mounted in a serial - parallel manner and I am happily getting as high as 300-315 watts on a good day. Overall, I am pleased with the purchase, performance, and the price. As spring approaches, I may get a few more watts yet, as I tinker with my tilt angles.

First, I admit this was a purchase based on price. Four, 100-watt panels cost about $52 each. That's pretty good. And it wasn't an impulse buy, I had these in my cart for a week before I made the purchase. They arrived a few days sooner than estimated, which was cool. But I still had to wait a few days for some good sun to test them out. The packaging was pretty good, as long as they weren't mistreated. they came 2 in a box, back-to-back, panels facing out, with a piece of sturdy foam about 1/2 inch thick. That wouldn't do much but keep them from scratching. The carton wasn't particularly rigid, but both boxes arrived in good shape, no damage or scratches to either panel. There was some amazing corner piece though. Instead of foam corners like I've seen in other purchases, these were thick rigid plastic, that actually could contribute to a temporary installation. I say temporary because the odds are they won't last. UV can damage plastic in under a year, IMHO. With a relatively bright winter sun, I got 23.5 volts from all four of these. I look forward to further experimentation.

Having had these for about eight months now, they lasted through the worst heat, and several ice storms. The voltage remains unaffected, and they are still performing as expected. I thought, for the price, that water and ice might work its way under the frame and bend it, but no visible bends or wear are found. With the right charge controller, you'll get some juice out of these all day. My neighbor has a barn light, and its close enough that I even read an output in the dead of night. Granted, its not enough for the charge controller to bother with. But these are a good purchase.

I have no complaints. Work better than expected. I've seen 17amps of charge coming from 2 panels which is more power than advertised which is not ideal. I overloaded a 20 amp solar controller with 3 panels. These panels should not have been able to overload my controller based on the power specs

Packaged and shipped very well, showed at my door step with no damage. Hooked up to my Eco-Flow Delta and was pulling 85 watts on a single panel on a mostly sunny day. Defiantly designed to be a permeant set and endure the elements. Overall would definitely recommend and buy again to expand my solar system.!

Deceptive advertising. These are not 100w panels as they only put out a max of 75w. I purchased 16 of these and unfortunately had already installed 8 of them before realizing that my control charger was only getting 300w per 4 panels, 600w total… in full sun. My other brand 100w panels (set of 4) was doing 400w. These are mounted 8 inches from the Eco-worthy panels capturing the same sun. The separate reading were from 2 BougeRV 30 Amp Chargers also sitting side by side on my power board and switching inputs between the chargers.

Montato su una pilotina di circa 7 metri , ha dato energia X gestire il mantenimento di carica X due batterie da 80 amp anche durante le lunghe soste invernali dove tra nuvole e brutto tempo di sole c'è ne poco, ho trovato le batterie sempre pronte e in forma, ottimo investimento tenendo conto che mediamente dopo ogni inverno di sosta sempre qualche batteria si perdeva a causa della scarica eccessiva.

Deja 3 commandés et ils sont a la hauteur de mes attentes. Test un jour de soleil en novembre 2016: Voltage moyen 19,8V Intensité moyenne: 4,9A Puissance réelle: 97W Les 100W sont a portée sans problème. Merci pour ce rapport qualité/prix probablement imbattable! Le chassis en alu est très resistant, la connectique est nickel Je recommande

Purchased a 100 w solar panels from Eco worthy to power a 300amp solar generator with 500 watt capabilities aboard my boat...The panel has performed well on winter overcast days averaging 10-15% charge with zero sun ...Overcast days it gives an average of 70% full recharge with the panel operating at 57 watts ...If I plug my solar generator into the mains it can only draw 59 watts which is it's max ... Yesterday in February sunshine ,and sun still low on the horizon the panel drew 91watts for a few seconds which I didn't think possible..but was averaging 59% to 79% most of the day...worth mentioning the first day I installed it on top of my boats canopy the Atlantic winter gusts blew it clean off the roof where it landed on the gang planks ripping the Anderson connector out of the solar generator as it took flight ...there was only minimum damage and the cables were so strong I reinstalled it the next day with no problems or disconnections..I would advise an Anderson adapter to MC4 connecters fir this if powering a solar generator and that needs to purchased separately...A marvelous sturdy panel which deserves nothing but the best review.

Función bien desde que lo instalé, no había instalado ninguna placa solar en la vida pero es un sistema sencillo. La única pega es su robustez, es un tanto débil, hay que amarrarlo bien con soportes adecuados o con lo que construyas tu mismo.

Im Laufe des letzten Jahres betreibe ich meine kleine Solaranlage mittlerweile mit 6 Modulen à 100W (12 Volt), sowie mehreren Steca-Ladereglern und verschiedenen Blei- und Gel-Batterien. Auslöser war, dass ich auf einem Hanggrundstück ein bis dato sehr trockenes, terrassiertes Gemüsebeet habe. Und da das Objekt nicht permanent bewohnt wird, wollte ich nicht das Hauswasserwerk am Strom lassen, wenn ich nicht da bin. Die Bewässerung mit einer 12V-Kreiselpumpe und Zeitschaltuhr funktioniert schon seit einem Jahr tadellos. Weitere Einsatzvarianten: Zwangslüftung im Keller mit einem 12V- Computerventilator, Frühbeetheizung mit 12V/120W-Heizkabel und Betrieb der 12V-LED-Beleuchtung der Terrasse am Abend. 2 ganz wichtige Tipps noch für alle anderen Solar-Interessenten: 1) Unbedingt darauf achten, dass das Modul richtig ausgerichtet ist und keinesfalls abgeschattet wird! Wenn unvermeidbar, dann besser eine Spalte, als eine Zeile abschatten. Letzteres bewirkt nämlich einen Leistungsabfall auf 25% (kein Witz!). Und ich kenne mittlerweile jede Menge Leute mit Solaranlagen vom "Fachmann", die sich nur wundern, welch hohe Leistung ich aus den Modulen heraushole. Vergessen sie alle Datenblätter! Das sind "peanuts" im Vergleich zu schlechter Montage. 2) Bei den Ladereglern benutze ich verschiedene Modelle von Steca. Bei diesen kann man mit einem Zusatzgerät oder gegen Gebühr die Ladecharakteristik an Blei- oder Gel-Batterien anpassen. Das erhöht die Lebensdauer der Batterie ganz gewaltig und senkt somit Kosten. Und, weil es immer wieder Leute gibt, die danach "How-to"-Mails verfassen: Das ist eine Rezension und keine Kunden-/Lebensberatung.
