This $270 solar panel has replaced my $500 gas generator when I camp. Using the gas generator costs me about $30 a day in gas. This solar panel will have paid for itself in 9 days!!! No more smelly, expensive and noisy generator interrupting nature and my camp!! No more getting up at 2AM because the generator is out of gas. Lying flat, it produces 10-13 amps an hour for at least 6 hours per day, plenty for a small camper. Plenty more electric is produced throughout the days hours as well. Easy to use, being my first large solar panel, I was worried about correct installation. From opening the packaging to hooking it up to the charge controller took me about 10 minutes. One last benefit- it is large enough to cover a substantial part of my camper roof and it gives me shade and a cooler camper. Easy, cheap, powerful solar panel!!!

Update: I repaired an mca connection and the panel started to work. It was producing 9 amps so I decided to keep it. Put it on the roof and now it’s producing 15 amps in direct sunlight. I am impressed. Purchased to renogy 200 watt flux panels and this is producing almost double the power. I upgraded to 5 stars because of the price difference. I will see how long this thing last though. Update: Amazon returned three and sent out one replacement. I was extremely happy that the replacement produced 9 amps, which is still underperforming of what the stated specs were. But, I thought maybe the first set were part of a bad batch. Not even a week later the new one has failed. I talked to several companies about this issue to understand better what could cause this issue. One of the companies I spoke with was Renogy and I decided to try them out. If their panels fail then it’s something with my equipment. If they don’t fail, then, these companies selling solar panels should be investigated. I will update any new information on this situation. I ordered two panels previously to ordering one from this company. The first worked but only produced about 140 watts of power. I was going to keep it because of the price even though it was a pain to get up on the roof. The third came in and didn’t produce any amperage. Yes, I know to switch my leads over on a multimeter. After this, I immediately tested the second only to discover it as well didn’t produce any amperage. I contacted Amazon for their number on file and it wasn’t in service. I have no choice but to repackage all of them and send these back.

Fit nicely on top of my 04 sienna. Had to remove the rails on top tho. Another thing, when I first used it i was getting around 350w peak which is amazing, however lately Its stayed sunny and and zero cloud coverage but im only getting around 240w average and ive owned this panel for about a week or two. Not sure if its the angle of the panel since its sitting flat on my roof. Ill test it out properly later on and see how many watts I can get. So leaving it 4 stars for now since I was able to get 350w at some point.

Product is ok but seller is awful. One of the two panels.does not work . I messaged amazon and the seller about this. Seller said they would send a single replacement panel. I took photo of the faulty panel and sent to them as requested. Seller then stated a replacement was ordered and they would provide tracking info as soon as it was available. A few days went by with nothing so I message again seller apologize and said it was ordered and tracking would be provided when available. Few more days went by then nothing, seller ignored all communication. Amazon initiated a return but being a 2 pack they scheduled both to be returned. One is mounted on the roof and in use. Amazon won't return just 1

I ordered 2 sets of 2 panels each. Order arrived within 1 week, drivers carefully unloaded 2 boxes onto their cart and wheeled into my garage. One of the four panels (coincidentally the one at the very bottom, as they layed them flat) was all broken. I contacted the seller, and they have an outstanding service, so they sent me a replacement panel for free. It arrived in 3 days. Pros: Size is slightly smaller than 4x6ft but only by a couple of inches, makes the panel movable by one tall person; Pretty solid, but my suggestion - don't try to bend, and handle with care + 2 people is better than 1; Voltage/power is about 80-90% of what is claimed, which is good and still a big value. Cables are long, very convenient. Cons: Don't order 2, they ship in one box and aren't wrapped as good as single ones. Single ones are packed better. Surface seems to be fragile, might not stand up to small hail. Might need to figure out how to cover these. Overall, well worth it!

Nice product, the plastic casting is sub par so it took modification to make all the pieces fit together, the carrying bag was damaged out of the box (strap ripped off) those teo things are the reason for 3 stars, but once assembled the quality seems nice, the panels are thin so they will seem flimsy-ish but still good quality, was getting over 150w per 200w array so im happy. Like i said they arent perfect, but once you get them setup they are pretty decent. Be warned the tripod is small so windy situations will not be your friend!

Purchased 2 of these now. Have them in parallel but will run in series when I get a more powerful inverter. I'm getting 550 watts out of the pair with less than ideal (extremely long cabling) at the lower 36vdc level. Once I shorten the cabling and put in series I'm certain these will crank out full power. They are are big and somewhat heavy but would rather have less panels and the wiring that comes with that. Neither we damaged in transit and feel they are a good value.
