Jeff over at Voltaic recently posted the first part of a five part tutorial on how solar chargers work. In this first tutorial, you’ll learn how to measure Open Circuit Voltage and Short Circuit Current. You’ll then move on to learn about measuring total power output, how to store power, how charge circuits protect the battery, and how to use stored power to charger a device. This is the perfect introduction to solar chargers for anyone interested in adding solar to their project. [Thanks, Jeff!]
