I’ll be brutally honest, you are not gonna get a cheap solar panel cheaper than this.That produces this well,That doesn’t mean they’re perfect,That doesn’t mean they’re efficient,But for the price you cannot complain,And if you go used there can always be problems.So, this is the best solution for a brand new price.Each Panel produces 2-4 AMPStotal Per panel Wattage 100-200 maxishIn Winter okayIn Summer GoodBut in general, if you want a good panel, you will have to put more money down, that’s just the way technology is right now.Also, customer support is perfect. If your customer support is bad.It’s because you’re not patient, and you’re not reaching them properly.Everyone have a blessed year, Goodbye

We recently had hurricanes in Florida lucky not much happen where live except the neighbors lost power because our retention pond flooded the road and up our front lawns it flooded theirs on the ground transformer but it didn’t flood our on the ground transformer so we didn’t lose power.I was lucky but made me think about next season and the fact my wife is recovering from a stroke in bedridden until she gets back use of right side at least her mind ok, slow recovery.But in the past, we been days without power and once 12 days without power but had lots of sun after storm passes.So getting some panels and a Solar power station (EcoFlow Delta 2 Max $950 on sale) that I can run some stuff for her like the TV and Fans and adjustable bed and a few mini fridges until power comes back online.I order first set and got them working with the power station, the power station can take 2 solar inputs so order another 2 set of these.The power station input is 11-60 volt and 15amp max so I can put 2 panel in series with 44 volts 5.5 amp max and then put 2 set of series in parallel for 44 volts 11 amps max I was getting real world 338 watts input to the power station so that like 84% of 400watts rated in full sunlight not bad at all.I only need 1 more set but I bought another smaller power station that only has one solar input because the DEAL on it was too good to pass a 1024ah 1800w output EcoFlow Delta 2 black Friday for $399.So now I have 1200 watts max but really real word more like 1000+ to change my two power stations.1 set of 4 $199, the next 2 sets of 4 $189.They are very well made and sturdy and are package really well, I only had to file down a few spots at the corners that had little sharp edge to it other than that Great Panels.

In answer to the question of โwhy are my solar panels underperforming their rated capacityโ I have some information that you might find useful. The rated capacity of these 4 panels is 400 watts. You probably already know that panel angle and whether the weather is sunny or cloudy can have a effect on power output. What you may not know is that how you connect your solar panels to the power station can also have a huge effect.My power station is rated at having 500 watts maximum solar input power so I assumed that I should have no problem connecting it to 400 watts of solar panels, but my power station has maximum solar input voltage of 60 volts and maximum solar input current of 15 amps. Each of the 4 solar panels has normal output voltage of not more than 12 volts but a peak output voltage of 19.5 volts and peak output current of 8.33 amps.If you connect the panels in parallel (positive of one panel to positive of the next panel and negative to negative of the next panel), the peak output voltage would stay at 19.5 volts but the peak output current would be 33.32 amps which exceeds the input current capacity of the power station. The power station would reject the current over 15 amps, so power output would be reduced by a little more than half and the excessive current could damage the power station. If you connect the panels together in series (positive of one panel to negative of the next panel), the peak output voltage of the 4 panels would be 78 volts and the peak output current would stay at 8.33 amps which exceeds the input voltage capacity of the power station. Power output would be reduced by about a quarter and you would again risk damage to the power station.In this example, I should be able to maximize power output by connecting the panels in series using a solar power controller. There are two types of solar power controllers, PWN and MPPT. PWN controllers are cheaper but they only reduce the voltage without a corresponding increase in the amperage so you lose power output. The MPPT controllers cost more but they increase amperage as they decrease voltage with no loss in power output. I have ordered an MPPT controller and am optimistic of getting optimal power production.

Decent product. Voltage is 22.

I bought 8 of them. Either all are faulty, they only read 0.03 amps, No matter how much sunlight I give them, or the angle. I connected four in series, and I only got about 0.2 amps that’s crazy! Disappointed as I was really excited to try them out.

these panels were very affordable. some other panel might be a little better,but a greater expense.I am new to this type of power ackup, so didn’t want tospend a lot of money learning the ins and outs,so these panels worked out great.

I highly recommend.I ordered four 100 watt solar panels. Sadly my first order., only two of the panels only arrived, I suspect it was the Amazon driver who stole two of the four panels because he did not leave a picture of the delivery. Two other items were delivered from Amazon and those the driver took pictures of but not the picture of the panels. I communicated this to Amazon and to the supplier and they refunded my money. I had to return the product but gave them a chance and reordered it, I am glad to say that all four panels arrived and they are excellent in quality and build. I appreciate the customer service and will definitely be ordering more products from this company. I highly recommend.

91 watts in February in Ireland!!!!
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.

Pannello dalla buona resa anche con poco sole e durante L inverno
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’รจ 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.

EFICAZ PERO ALGO DรBIL
Funciรณn bien desde que lo instalรฉ, no habรญa instalado ninguna placa solar en la vida pero es un sistema sencillo. La รบnica pega es su robustez, es un tanto dรฉbil, hay que amarrarlo bien con soportes adecuados o con lo que construyas tu mismo.
