Car Charger Schematic

Designing a Solar Phone Charger

Grades:
7-12
Learning Goal(s):
1. Students will be able to design a device that can charge a phone with 4 hours of sun a day. 2. Students will use collected data and be able to support their design – i.e. the data will show that the unit will produce enough energy to charge a phone given it receives 4 hours of sun a day. 3. Students will also be able to calculate efficiency from their power calculations. 4. Students will be able to compare efficiencies of their circuit to others tested in this unit. 5. Students can calculate how much energy 4 hours of sunlight can produce on the solar modules they will use.
