This extra power boost adds significant value to its already stellar performance, ensuring you get the most out of your solar investment. The efficiency of the 100-Watt Solar Panel is truly commendable. It efficiently converts sunlight into electricity, ensuring a steady and dependable power supply. This is especially crucial for those relying on solar energy for off-grid setups or emergency power sources. What sets this panel apart is its durability and build quality. Crafted with high-quality materials, it not only provides exceptional performance but also withstands various weather conditions. I'm pleased to share that it arrived in perfect condition, undamaged during shipping. The robust design ensures the panel's longevity, making it a smart investment for anyone looking to harness solar energy for an extended period. In conclusion, the 100-Watt Solar Panel not only lives up to its name but also surpasses expectations. Its impressive power output, efficiency, and durability, combined with the bonus of 102 watts on sunny days and damage-free shipping, make it an excellent choice for anyone seeking a reliable solar solution. I wholeheartedly recommend this panel to those looking to embrace solar energy with confidence.

I bought three of these back in August 2023 and connected them in series. I consistently get between 350 and 420 watts out of them, and I always get at least something useful even on the cloudiest days. They were easy to install too. Not tiny like the 100 watt panels on the market today but small enough for one person to easily handle during installation. They're durable too since they survived three hail storms one of which damaged other panels that were installed in my general area.

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!

Totally understood that these panels, regardless of brand, rarely ever put out their rated wattage, but this single one has been averaging more like 90 watts on a clear, sunny day. Still, great value for the price point and it serves it's purpose. The panel doesn't feel cheap or flimsy and construction is made of quality materials. My use case: Currently charging my Anker Solix C1000x, which powers my fridge and while camping, my kettle and Starlink Mini while keeping all of my devices charged.

Excellent and very efficient

These panels put out!!! They put out 848 + on a good day and are excellent on cloudy days also I installed 4 of them on my 19' RV and a REDODO charge controller, Redodo 40 Amp MPPT 12V/24V DC Input Solar Charge Controller with Built-in Bluetooth Module, Parameter Adjustable LCD Display LED Indicators , to a set of 2 each ECO-WORTHY 12V 280Ah 2 Pack LiFePO4 Lithium Battery with Bluetooth, Low-Temp Protection, 6000+ Deep Cycles, 7168Wh Energy, Support in Series/Parallel, panels use 10 Ga wire . They put out 848 + watts on a good day , they are installed kind of tight to my roof so the backside does not do as well as it could if they were raised up more, which is not practical due to wind and Gas mileage implications when towing , They do put out more then 200 watts each and are well made they go with a 24Volt system and 24 volt DC to 120 VAC Giandel 24V Pure Sine Wave Power Inverter 3000 Watt Approved by ETL converts DC 24V to AC 120V with Dual AC Outlets with Remote Control 2.4A USB and LED Display , I can run heaters and or my roof top AC for many hrs using this setup..

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.

The panel had one dented side. Everything else was in great shape, and the dent wasn't obstructing the frame integrity. I mounted this to an EcoWorthy 40inch+ adjustable angle ground mount and have it on the ground outside the house in my backyard. I am pretty impressed with the panel on overcast and rainy days. Full sun in winter - Max I pulled was 181 watts out of 200. (I expect this to increase during summertime.) Overcast with little to no sun in winter - Max I pulled was 40 watts out of 200. Pouring rain - Max I pulled was 12 watts out of 200. (Expected 0 TBH.) POSITIVE: Overall, getting ANY wattage from a storm with pouring rain all day is enough to sell me on this panel. Essentially a trickle charger for my Bluetti EB70s on rainy days. NEGATIVE: Offical specs show the VOC max to be 28.1v, which exceeds the EB70s limits. I have had this out on a cold day, pushing upwards of 28.6v. The back of the translucent panel is also a laminated plastic-ish coating, and I wonder how long this will hold up before yellowing or deteriorating from element exposure. OVERALL: I rolled the dice and plugged it into the Bluetti EB70s since the generator has a kick-off for over-voltage protection over 28v, and even at 28.6 VOC, it didn't trigger or stop the unit from absorbing solar. The unit still pushed in great wattage, and as the sun warmed the panel up, it quickly dropped to 27.1 VOC and below. I think this is one of the best-performing panels I have tested for a 200w. Again, I have not used this in the Summer sun or Summer heat, so only time will tell. 4/5 Stars since it came with a small dent and went on sale immediately after I purchased it. (lowest I have seen was $190 on black Friday.)
