Set name: P-Type 100W 2pcs
Overall I am satisfied with these 100 watt panels. Packaging has been consistent without any damage after I have purchased a total of 8 panels. My panels are mounted flat on top of my camper. With four panels, I have seen as much as 350 watts at a non ideal mounting angle. This is 87 watts a panel. I've since moved to 7 JJN panels on my camper. I cannot comment yet on total power output as it's been cloudy. However, if I can manage 87 watts a panel, I'm expecting 600 watts. Crossing my fingers for 700 watts. I've yet to see 100+ watts from the 100 watt panels like some reviewers. However, this could be due to angle. Mine are all wired in parallel. Lastly, I have 1 panel (8th jjn 100 watt panel) powering my seldom used shed. It getting the job done for led lighting purposes and light duty power usage. All my panels are on MPPT controllers with appropriately sized wiring and limited voltage drop. Overall, I'm happy with my panels vs price paid. I'm curious to try the 200 watt panel and maybe move my 8th 100 watt to my camper. I will update this review with any relevant information at a later date. UPDATE- 5/26/23 Installed an 8th 100watt panel. I produced 720 watts of solar power yesterday in not ideal conditions. Intermittent cloud cover, non ideal solar panel angles due to being mounted on camper roof. This is 90 percent of total advertised output. I am certain at this point that if all panels were pointed at ideal angles vs sun position, they would produce the 800 watts or more. Overall, I am very satisfied with these panels. Now off to upgrading my battery bank. Update 10/21/23 Upgraded to 10 panels (1000) watts on my camper. I am currently only able to achieve 65% of rated output. Please keep in mind that in June I was able to get up to 95% output and this is on a flat roof, no angle. I tested all my panels at 3.5 amps with a short circuit test via a fluke clamp DMM. Consistent output readings were observed. I then took 2 panels and angled them until I got max output facing the sun and achieved 5.5 amps. It's obvious that angle and direction in relation to the sun can make a drastic difference. 3.5 amps at 20 volts = 70 watts (70%) 5.5 amps at 20 volts = 110 watts (110%) It did not take voltage readings, so I'm going with a ballpark voltage of 20. However, panel angle at optimum made a difference of 63%. All this to say, the panels checked out and are working correctly. Panel angle makes a drastic difference. I will say my latest shipment of two panels I did experience slight shipping damage and the glass has light scratching. Update 3/2024. Still utilizing a non ideal angle. It is early spring in Texas (Northern Hemisphere) and the sun is not at maximum height/ angle to provide max solar power conditions. I have 10 JJN 100 watt panels, I am currently producing 810 watts out of 100 watts of panels. For a total output by percent of 81%. I suspect this may go up in late spring into summer. I will post a screen shot of my output. Which shows .81 KW or 810 watts. Still impressed and happy in 2024. Stay tuned for an additional 2 panels in the future. Update 4/19/24 Later spring now in southeast Texas. Partly cloudy day with intermittent sun. Was able to produce 980 watts (.98kw) on historic chart with an instantaneous reading of 920 watts (.92kw). This is 92% of the 1000 watt rated output with panels lying mostly flat. To give you some insight into what I am able to accomplish with this. I have a 48volt 300AH power bank of Lifepo4. I live in my camper currently full time. Fully charged at 58 volt, I have about 17.4kwh of power storage. 48 volts is not full capacity on 12voltX4 bank of Lifepo4. I run my microwave, phones, refrigerator, blow dryer, laptop, cellphone charging, vacuum, lights, tv, Xbox, PC, exhaust fan, etc off my system. I do not run my AC or water heater off solar. Future plans though. By midday on sunny day, I have completely recharged my batteries. Excellent performance. Update- 4/21/24 Cold front came in on a cloudy day, clouds broke to full sun. I was able to achieve 1060 watts (1.06KW) on ten 100 watt panels (1000 watts). This wasn't short lived as I was able to achieve 1040 watts a few minutes earlier. Typically, it would be much hotter in April here. Current ambient temperature is 62F at around 1pm. I believe this set the stage for a perfect environment of cooler temperatures and full sun . With all this being said, I was able to achieve 106% of rated power at non ideal solar panel angle. They are nearly flat and oriented North/South almost perfectly. With all this being said, I should have upgraded my review rating to 5 stars long ago. Unless the panels produce a crazy high number, this likely concludes my updates. Please don't hesitate to use these panels. Photos of all outputs have been uploaded and verified with secondary shunt based power monitor.

Had Them For a While... Back... Before You Needed Medical Attention For Your @nus From The Artificial Inflation... and The Hidden Taxation Scheme Through The Tarriffs... They Have Worked Great So Far... and Can Output More Than 450 Watts On a Great Solar Day... and if You Have The Right MPPT and Wire Rated For The Output... I am Glad I Got Them... But Wish I Had Enough To Buy Bulk Panels... I Could Have Got about 2100Watts Worth Of Panels instead Of 1200Watts... Glad I Bought Them Though... Unless Your Selling Your Neighbor To The Meatwagon...

These 200-watt JJN bifacial solar panels are an excellent value for the money. I have 4 panels now (and plan to add 4 more), and I use them to charge a portable solar generator. In good sunlight, I have seen the 4 panels generate 880 watts of power, which equates to 220 watts per panel, and is well above the stated 200-watt rating. This makes charging my generators even quicker than normal. They are high quality, durable, and are easy to install. The MC4 connectors make it easy to connect to my existing system. They are relatively lightweight and easier to manage than 400 watt panels. I would highly recommend these panels.

I was looking for some rigid solar panels for my power stations to replace the portable ones I was using. I decided on JJN panels because the reviews were so good. I first bought 2-200 watt bifacial panels and found they put out more power then the 220 watt bifacial portable panels I had. I bought a larger power station and bought 2pcs 425 watt bifacial panels and found they out out much more power then the 2-400 watt portable panels I also had. We have been having many days of over 100 degrees weather and these panels exceeded my expectations by the amount of power they generated but what really impressed me is even on very cloudy days these panels still put out power, not much, but my other panels did not put out any power during cloud cover. If I decide to buy more solar panels I will definitely buy JJN panels again.

I'm using this array as a ground mount array to power my Ecoflow battery generators. I have used portable solar panels in the past but wanted a semi-permanent solution. These seem to do the job. I'm currently taking advantage of the summer sun and laying the panels flat. AFAIK, per the ap readouts, I'm getting 80%+ of the 200w rating during cloudless conditons from 10a to 3p. Panels look durable and arrived in good shape via UPS delivery. This was a prime day purchase but wouldn't hesitate to purchase from this company at full price.

This is a very good solar panel. It really does hit 425 watts and beyond. During the Atlanta summer it seems to generally stay more around 380 watts, but it has hit 430 watts. I liked it enough to buy another one and it hit 450 watts. These are very heavy, so not portable, and also big, so I don't even think I could fit them in my car (a compact SUV). I have them in my driveway now and hopefully can install them on the roof in the Fall. JJN includes some good information about installation and both panels arrived quickly and without damage.

Mine is a 400 watt panel and it is one of the best solar panels I have ever owned I love it very heavy but impeccable quality and performance I will definitely buy it again I just recently purchased a 200 watt solar panel and thought I ordered the same manufacturer but it was different and I was very disappointed with the quality and quality

I installed two of the 425W panels in parallel in different locations, extending my solar window to 8 hours. I am consistently measuring 425W delivered to my EcoFlow Solar inputs. I have a pair of EcoFlow 400W portables as well, but they only put out 320W and cost more. I mounted the two panels using renogy 50inch panel mount kit, it fits well and looks good. These panels seem durable and easy to maintain, highly recommend them.
