small off grid solar

[Pastorcasper 2.0]

So, I'm looking at solar power to get for a friend out on the Navajo Reservation (Arizona US). It would need to be quite durable as they have lots of small sandstorms, whirlwinds and sometimes hail. It doesn't need to have to be able to put out lots of power, it just needs to be able to charge a few devices off of USB. I have so far found this...

1) does what i have found look like it would work well and give enough power etc.
2) is it worth the price
3) are there better alternatives

I think you're spending a bit too much on the panel, you can get more power for less with a proper roof mount panel. Plus those are designed to survive the environment for 25 years on average. https://www.wholesalesolar.com/shop/solar-panels 

 

As for that battery, I tend to think you're spending too much there as well, but I'm not sure. Batteries are generally expensive per Wh, but I bet you could find or build a cheaper option.

the only problems there, are getting someone to install it, and wether the roof can even have something mounted on

they also currently have a kit from harbor freight (i heard those arent that great), but they had a whirlwind that picked it up and threw it a bit and its all cracked. it still works somewhat but obviously not as well which is why the ones i sent could work well. I am however looking here to see if there is a better alternative. *shrug*
