sadly so far it is very hard to actually charge batteries.

You can find cheap regulators :

I think you are vastly overestimating what Power you will get from a solar panel.

It's all about how much and where you invest off course , but even this old article shows how much potential solar power has :

We could have "free" global solar energy
If you google Gobi desert + solar energy you see the Chinese understand that:

You could pump some water in a high ground reserve and when you need power, use the gravity and water to power hydroturbine! Grin

I laughed. Yeesssss of course.... A kinetic battery, why not?

Let me just pump 10 pool worth of water over my head, to last the night on my S5 Tongue

Thank you all for contribution
