Spec looks good, although this FAQ question gave me pause:

Most solar cell manufacturers warrant a 25 year service life for things like rooftop modules. The 4 to 5 years specified by Blitzwolf seems very short in that context. Is there a reason why the service life for this portable panel is so much shorter?

I believe it’s because these portable panels are subject to more use and abuse being stuffed in a backpack, folded and unfolded numerous times and are generally put in harm’s way much more often than a rooftop panel. True, rooftop panels must contend with weather, but they aren’t being physically manipulated over and over. My thoughts anyway.

Interested if the price is right.

PET, polyethylene, is going to get damaged by the sun. You’re not going to see much of that on roofs.

Good point, that makes sense.

The problem’s not the solar panel as such, it’s the tradeoff between PET encapsulation being lighter and less fragile but subject to UV damage, or toughened glass being UV proof but very heavy.

I already have various panels with PET encapsulation, and I haven’t seen any degradation yet, so that puts my mind at rest. It also occurs to me that UV damage tends to be concentrated near the surface of a material, so it may well be possible to use an abrasive polish to repair the PET by removing the surface layer if it does start to yellow under UV. An experiment to try, if I ever need to :slight_smile:

All very true, but those effects tend to cause sudden failure, whereas the FAQ seemed to be implying gradual failure over time. The gradual failure aspect was the thing that piqued my curiosity.

Is there a review available around? I'm interested if it has autocoding for output, if it reaches 2 or 2+Amp on a single output, and if it has autorestart if sun recovers after a situation of overcast.

Years ago mjlorton tested all these functions and compared them for various model in a pretty controlled enviroment in a youtube video.

It is a brand new product. Review should be available a few weeks after sale starts.

According to their FAQ no.7.

When moving the BW-L3 from shade to sunlight, you need to reinitiate charging by disconnecting and reconnecting the device. If the device is not disconnected and reconnected, it can take up to 10 minutes for the BW-L3 to resume charging the device. The exception to this procedure is the iPhone; you do not need to reinitiate, it will quickly resume charging when moved back into the sunlight.


I'm interested.

It’s for preorder now @Banggood for US$49.98; do we get a better price via this groupbuy!?…

Lets hope so, I’m not interested at that price…
