PV Modules & Cell Technology (Topic 1) in Module 3 – Solar-PV-NABCEP-Associate (BG)

PV Modules & Cell Technology

A PV module is made of many cells wired together and packaged for durability outdoors. The exam typically focuses on what module ratings mean and how conditions affect output.

Common ratings

  • Pmp (or Pmax): rated maximum power (W)
  • Vmp / Imp: voltage/current at maximum power point
  • Voc / Isc: open-circuit voltage / short-circuit current

Real-world effects

  • Higher irradiance generally increases current and power.
  • Higher temperature generally decreases voltage (and can reduce power).
