Requirements

  • Basic electrical or solar foundation recommended
  • Familiarity with AC power systems (voltage, current, frequency)

Description

Bridge the gap between residential setups and heavy commercial/industrial infrastructure. Learn three-phase 415V/480V electrical distribution, commercial cable sizing, roof structural integrity checks, and mini-grid architecture.

The course takes students from the fundamentals of solar energy and photovoltaic technology through the identification and application of major solar-system components, electrical load assessment, power auditing, roof characteristics, and the factors that influence solar-system design and installation.

A dedicated Solar Companion Technical Reference provides additional high-level engineering knowledge covering solar inverters, batteries, solar panels, and solar charge controllers, including their ratings, characteristics, sizing considerations, configurations, and applications.

Who this course is for:

  • Solar technicians aiming to enter commercial and industrial sectors
  • Industrial facility managers and plant engineers
  • Renewable energy project coordinators
