I’ve had good experiences with Anker and Yeti solar panels. The Yeti definitely works to charge their batteries (I had a Yeti 650 that I had hooked up to solar panels all weekend and it never died and helped my group of 20+ people charge their electronics), but have since downgraded and just have a simple Anker charger:

Solar doesn't work like how you think it works. Solar is like using a dripping faucet to fill a bucket. If you think you're going to charge a phone placing it in the sun for 5 mins you're in for a huge disappointment.
If you plan to basecamp awhile you can get an Anker 21w panel system and a two 13,000mah battery packs.
How this works is... During the day when you're out hiking you position the solar panel in the sun at your base camp. It will roughly take a full day to fully charge a 13aH portable battery if the conditions are good. Now you have 13Ah of power or enough portable battery to charge your phone at least 3 times. You put that in your backpack.
While you're carrying one of those 13,000mah battery packs you put the other on the solar charger at camp so it's fully charged and ready to go when you get back in the evening. When the one you're carrying is dead, you swap it for the charged one.
You never actually plug a phone directly into a solar charger as that's insanely inefficient. Same as houses with solar power, they are not powered by the solar panels they're powered by battery banks that are recharged by the sun.
If you're going on a thru hike without a basecamp or stopping during the day? Solar is not for you. Carry some high capacity portable batteries and limit phone use.
Solar works really really well without a lot of infrastructure or investment. A cheap camping panel, charge controller, and inverter can cost you a couple hundred bucks new, less if you can scavenge, solder and dumpster dive. Add a $80 deep cycle marine battery and you can keep some lights, your usb batteries, and a few devices happy all week.
Stepping back a bit I use one of these https://www.amazon.com/Anker-Charger-PowerPort-iPhone-Galaxy/dp/B012YUJJM8/ref=sr_1_1_sspa?ie=UTF8&qid=1514404002&sr=8-1-spons&keywords=backpack+solar+panel&psc=1
It outputs directly to USB and keeps a couple battery packs I run LEDs off of and a small tablet I use for an occasional late night movie going all week. It's light and folds up into my backpack quite well. It's been going strong for three years now.
