These are mere ideas:

How to measure charge in batteries:
Is it not so that the mass fraction of lead is roughly proportional
to the state of charge? If so, ultrasound or magnetic fields or natural frequency
of vibrations or pH of the electrolyte could be used to meter the charge.

how to utilize solar power:
instead of using a narrow bandwith in solar cells, with a low
efficiency of energy conversion, why not just focus the sunrays
to create a large temperature difference, and apply an appropriate
heat engine?  The total efficience from sunlight to rotating wheels
should approach 60%.
