Use a full-sized solar panel to power a large battery
Use the large battery to power a raspberry pi.
Use the large battery to power a small laser through a voltage regulator that reports available power.
Add an on/off switch to the laser circuit that is controlled by the pi.
Point the laser at a diffraction lens that illuminates a small solar panel.
Power a small battery with the small solar panel.
Use the small battery to power an arduino through a voltage regulator that reports the available power.

Remember: we regulate the voltage, everywhere. Only voltage can force current where it is not wanted.

Can we keep the arduino powered 24/7?

Gear

laser goggles
100W solar panel
solar power regulator - I have no idea if this will do the job yet... but it's on the way!
Raspberry Pi 3
$45 300mW laser
Arduino Uno
Breadboards
Multimeters (two hand-held, two usb inline)

More gear that we may not need

cheap <$1 5mW laser
Raspberry Pi 3
Arduino Uno
