## Questions & Answers

**Q: Will this be good for mounting it on my roof**
A: You could but would need to think about waterproofing the port.

**Q: Can this be left outside through out the year, I'm think of fixing it on my roof thanks**
A: It is very robust and the waterproofing is a kind of solid plastic coating that look excellent.  The problem would be the USB interface wear you plug in your cable. If moisture gets in it could rust and corrode. If you can work around it should be good. Be mindful its not huge.

### ⭐ Broken after just a few uses
*by R***R on 5 August 2024*

This is a great solar panel when it comes to fast charging. Works well and even in cloudy conditions. Looks great and Packs really well as well. But... On the inside it's a cheap poor manufactured product. I am on my second panel and both of them broke just after several uses. Apparently where they fold, there's a circuit misconection which comes apart and now it works only after loads of fiddling it in awkward positions. It looks like it's a common defect from other reviews, so. It's just poor design /manufacturing on the inside.
