Solar chargers use solar energy to power my electronics, neat! How do they work?
Short answer: Sunlight hits solar panels -> solar panels generate electricity -> electricity flows into battery -> battery outputs clean power on demand to your device
Long answer: We’ve created a five part tutorial to take you through every stage of the process. Solar is obviously much less predictable than plugging into the grid so we’ll be focusing both on specifications and what to expect in the real world. Bring along a multimeter and some parts from Radio Shack and you can get a pretty good idea of how exactly how solar charger work.
