Size: 200w Bifacial
Below is my original review. I thought it would be best to post an update for those that are considering these panels. I’ve had them for enough time and through a season to update with real specs: See my photo! These panels deliver FULL wattage to your storage and loads. I have these in series/parallel for my 24v controller and inverter. It’s summer 2024 and the other day we had a power outage affecting 5k homes in the area. My shop was running as if nothing happened. Full on AC, compressor, lights, power tools, chargers. These panels pushed 15a @24v with no problems. The panels are staggered in age yet they all perform the same and deliver to my storage array and grid. 4 of these are enough to power my shop for 6+ hours. The next day, my storage was full by 8am. Granted this is summer, however this is the ideal time to rate these and judge them for what they can do. Some other reviewers state they don’t deliver but I can assure you that my panels deliver equally, efficiently and are working well with the environment they are in. I hope this update helps inform you to the longevity of these panels. I purchased these panels 2 at a time last summer and I now own 8 total. It’s been more than six months post deployment and I have to say that I am extremely overjoyed by the results of these panels. One did arrive completely shattered but the customer support is amazing and I had another panel on my door in a few days. These are durable to a point but they are made of glass so if you get a broken one, don’t sweat it! I configured my panels to work as series/parallel to a solar combiner box. From my solar combiner, I send the combined power to a controller that then sends the power over to a bank of LiON batteries @1200ah 24vdc. In turn, a mega beefy 240v@60hz inverter draws from the batteries at 24vdc and sends two phase AC over to the ATS (Auto Transfer Switch) that controls the balance between line and inverter. This winter, the biggest draw was my electric shop heater which runs on a timer. Most of the winter months, I managed to see a daily use of pure solar to power my entire shop. Only a few days in January did I see the switch trip over to line power. Thanks to these panels, I can run my shop exclusively on solar! My compressor, lights, tools and even my welder all are powered by solar! The whole situation would be impossible if it were not for the affordable cost of these panels. I plan to add a few more and push my luck with charging an EV using solar. I just need more storage and I’m golden! This is a fantastic purchase and the price is cutting the competition in half!

UPDATE 10/10/2024 Definitely worth buying these panels. I was able to setup the panels at the proper angle for this time of year and was able to achieve above the rated 400 watts of my two 200 watt panels. I was able to reach 422 watts. Very happy with these panels. I will be purchasing the new updated version of these 200w bifacial panels. Thank you JJN Original Review: Just picked up a pair of the JJN bifacial 200w panels and so far so good. They arrived packaged well with no damage. They look great with the black aluminum frame. They seem to be well made both panels looked very consistent in build quality. The panel size is manageable to maneuver and install. They are functioning as intended, I snapped a screenshot at the highest I saw which was 393w and that was not even trying to aim the panels properly. Good value for the money when they are on sale. I will be picking up another pair on the next sale.

Very happy with this JJN Bifacial 200 watt Solar panel. Most panels are lucky to produce 70-80% of their rating. This one has produced as high as 220 watts (110%) and just under 15 amps when everything is just right. In full sun I am getting 195 watts consistently. You'll notice the gig a built, it is on wheels and easily adjusts the inclination which allows me to follow the sun pretty well; adjusting it about 6 times a day (I am retired). Which is a part of the consistent performance I am getting. I live in Phoenix AZ, as luck would have it shortly after getting the panel I had several overcast days. I was surprised that the panel still was producing 90 - 100 watts and just under 7 amps anyway. Which was as much as the 120 watt portable panel I replaced did in FULL Sun. I suspect the effective results are also a function of the HQST MPPT 20 amp solar controller I am using combined with as high as 25 volts from the panel (higher than the 23.4 optimum operating voltage spec of JJN). Believe I would have lost watts with a PWM controller. Good MPPT controllers maximize these extra volts into watts. The 10BB nature of the panel is likely also part of the excellent results. The bifacial feature may also be helping, although I would point out I did not attempt to try to do anything special behind the panel (the house is white and that may have helped a bit). This is a backup system for losing power. I have successfully been running a 5 cubit foot chest freezer with an inverter and a 54 quart 12 volt portable refrigerator directly, for about a week even with the 3 of the days being overcast. I am using a DJLBERMPW 12V 100Ah LiFePO4 Lithium Battery and the solar panel to keep it charged. Interested what I will get here in summer 5 more hours of more direct Sunlight. (PS: If you noticed the bricks, I originally built it for the 120 watt portable panel I mentioned. Going from the 7 lb. portable to a 24 lb (normal for it's size) 200 watt panel required a new frame and counter weighting the increase in weight of the 200 watt panel with those bricks. If you want to build something similar make your you buy locking wheels for underneath)
