Materials List: Concentrating on the Sun with Photovoltaic Solar Panels

Each group needs:

  • mini PV panel ($10-30; available online; do a product search for "small solar panel" or see the Solar Panel Source Information attachment in the Photovoltaic Efficiency unit)
  • alligator clips
  • wires
  • multimeter ($10; available online; see the Solar Multimeter Source Information attachment in the Photovoltaic Efficiency unit) (experiment can be run with either one or two multimeters per group, see Procedure section for details)
  • cardboard, a 2 ft x 2 ft (.6 m x .6 m) piece
  • scissors
  • protractor (or use attached Protractor Printout, two per sheet, print out and cut apart)
  • aluminum foil
  • Investigation Worksheet, one per person
  • (if not using the sun as light source) clamp or desk lamp with 100W incandescent bulb (~$8; best for each group to have their own, but teams can share if necessary)

To share with the entire class:

  • duct or masking tape
  • paper and pencils, for drawing and sharing design ideas

Note: The non-expendable items (mini PV panels, multimeters, wires with alligator clamps, lamp and light bulb) are reusable for the entire four-lesson unit, as well as other projects.
