Energy from the Sun Workshop

Introduction to Photovoltaics

electricity basics
Electricity Basics
  • Electrical Current – how many electrons
  • Voltage – how hard they’re pushed
  • Power – what they can accomplish
  • Circuit – where they can go
  • Series Circuit – one pathway only
  • Parallel Circuit – so many choices!
parallel vs series circuits
Parallel vs. Series Circuits

Parallel circuits

  • maintain potential (voltage is constant)
  • Current is divided among components
  • If one light goes out, the others stay lit

Series circuits

  • maintain electrical flow (current is constant)
  • Voltage is divided among components
  • Easy to open circuit quickly
dc vs ac
DC vs. AC

Direct Current

  • “Battery power”
  • Electronics use
  • Requires prohibitively high voltage to transmit over long distance

Alternating Current

  • EASY to generate
  • Can be transformed in voltage
  • Can be limited while keeping voltage high
  • Can be transmitted over long distance without super-high voltage
