[High Efficiency]JJN 300w solar panel kit adopt the 9BB solar panel cell design and are made of excellent Grade A+ cells. The conversion rate is as high as 22% and each solar panel can provide about 1500 Wh of electricity per day (depending on sun availability). It has better quality and efficiency than 5BB and Grade B solar panel cells.
[Upgraded Design]JJN monocrystalline solar panel upgraded the latest half-cut cell technology, which makes the solar panels obtain better and more stable performance. Compared to regular solar panel, half-cut cell technology can reduce power loss, lower solar panel temperature and reduce the impact of shading on performance.
[Easy to Installation]Each 12 Volt solar panel has specially designed pre-drilled holes for easy installation. It can fully meet the installation needs of various applications. It is compatible with JJN’s Z mounting Brackets in the kit. At the same time, we are equipped with two pairs of wires, which can easily connect solar panels, controllers and external batteries. There is no need to choose additional wires.
[What You Get]JJN 300 watt solar panel kit are very friendly to starters. The included 40A charge controller can make this solar system suitable for different 12V batteries, such as Wet, Gel, MF, EFB, and AGM. It can be applied to RV, Camper, boat and home green energy storage.
[Long Warranty]As a professional solar system manufacturer, We promise an extra-long transferable power output warranty of 25 years. Whenever you encounter any problems, JJN Solar Panels Service will actively provide you with professional off grid system solutions.

Overall, it’s a great product. I like the tri-fold design. Compared to the bi-fold designs, its size, when folded, is much smaller. The monocrystalline material makes the product very aesthetically pleasing. The dark, shiny black color looks really nice. On a clear summer day it outputs around 70W power, with the current 4.25A. This is not bad for an affordable solar panel. The power output could have been better, but I guess for this price, I’m okay with the result.
Here comes the deficiencies.
(1) This ALMOST makes me wanted to give only 4 stars instead of 5. Although the solar panel is of good quality, its accessories are not. I have to connect its extension cord and the my power generator’s charging cord through the MC-4 connector. Its MC-4 connecter is stuck with the MC-4 adapter on the other charging cord. I’ve spent hours trying to separate them but it seems that the adapter on this cord was not the right size. No matter how hard I press the pins this adapter won’t let it out. This could be extremely frustrating. Anyway, given this is just an accessory and you can easily buy another one on Amazon, I still decided to give it 5 stars. HOWEVER, future buyers should be aware of this issue.
(2) The Velcros on its bag is not very strong so the bag was always left open. Sometimes things would fall from it unexpectedly.

Hooked these up and was reading 191 watts which is good for the beginning of December. They appear to be good quality overall. My only concern is they have a lot of tiny surface scratches. Not likely to impact performance, but makes me concerned about the surface being easily scratched. It would be nice if the leads were longer.

Easy to set up and they charge fast. We have them charging 3 batteries and they keep them running our camper. Will definitely buy more when we expand our solar. They are built sturdy too but a little heavy.

We got two pair of these jjn solar panels to replace some older ones that I had one that had gone bad and another one that had dislodged itself and flew off not sure how or where.
The first panels we got are now going on about a year and a half to two years old.
The second was around 6 months later.
There are 400 watts total between the two of them and they have performed flawlessly.
I do notice more power in my meter and being on the top of an Airstream they’re not all flat or at the same angle.
Some are on one side some on other so you have angles they’re all at different angles to sun.
Highly recommend them.
I did replace some older style panels same watts, and these are smaller believe it or not for the same power. Total on roof is 600 watts, not all JJN panels.

Really nicely made. Panels heavy duty. It’s so nice all the wiring perfect.
