Students will become familiar with circuits, cells, batteries, and photovoltaic cells, then plan, build, test, modify, and re-test a small solar battery charger designed to maintain batteries from a particular device.
Students will build series, parallel, and parallel series circuits from a schematic diagram. Students will master the basic concept of battery charging. Students will be able to plan and build solar battery chargers for a given battery system. Intermediate students will calculate time to charge a depleted battery to its full capacity given specifications of a solar module. Students will be able to explain how a solar cell works with diagrams and words. Students will use a digital multi-meter to measure voltage, current, resistance, and diode polarity.
