Solar Specialist Platform Level 1

Pass your “Level 1” first before attempting “Level 2”. Level 2 is more advanced than the “Level 1” test and requires a more complex knowledge of principles and calculations.

Level 2A Test Categories

With the “Level 2” there are 12 categories in the test

  1. Electrical Theory
  2. Module technology
  3. Irradiation
  4. Surge Protection and Earthing
  5. Power and Energy
  6. Temperature Co-efficients
  7. Mounting structures
  8. Electrical Switching & Safety
  9. Batteries
  10. Standards & Safety
  11. System Sizing
  12. Drawings and diagrams

Preparation for the test

Most candidates display varying levels of skill and theoretical knowledge. Some installers have attended multiple courses and others may have spent countless hours doing research without having ever attended any courses. Disparate research and training activities have resulted in consumers not really being able to distinguish between knowledgeable, experienced and or hoax contractors. The SSP is a scale-able quality assurance platform that allows all stakeholders to participate in the initiative.

Most training providers that offer training for solar PV installers, should be able to provide the required information within their training material in order for students to pass the test. For a list of training centres aligned to the curriculum of AREP, please contact us via e-mail.
