Solar Panel and Boron

Has anyone tried using one of these solar panels with the Boron?

I’m assuming this comes with some type of voltage regulator.

BUILT-IN 3300mAh CAPACITY BATTERY INSIDE OF BRACKET: solar panel kit come with built-in rechargeable battery, don’t need extral rechargeable batteries

If combined with the Boron battery, this good be a really nice setup ?! Thoughts?

You can just take the output from a solar panel assuming the output is within the voltage range and use the PMIC on the Boron to charge the LiPo battery - I’m sure you can use this as well.
