Operating a LED with solar energy

Principle

Small photovoltaic systems are used e.g. for the direct supply of small devices or for lighting purposes. In general, this applications require higher voltages than the ones that a cell can provide. Therefore, several cells are connected in series. In most of the cases, LEDs are used in solar lamps. The aim of this experiment is to determine the voltage that is necessary to light a LED with a solar cell.

Benefits

• Part of a system solution - Easily expandable for further experiments
• easy teaching by using the demo board for demonstration
• Simplified implementation: all pre-settings already prepared
