  2. Course Complexity

    • This 2 day online advanced solar PV design-and-install course was created to address the need for organisations or small businesses that require in-depth information on sizing, assessing and the installation of solar PV Systems. The content is ideal for experienced installers, engineers and or electricians involved with solar PV technology design and installation.
  3. Course Assessment

    • An assessment in the form of an online test is done after the course has been completed. The test is done in the students own time and is additional to the time allocated to attending the course. Students are expected to register for the online test at the following address. (AREP P4 Level 2 test - 4 hours)

  4. Introduction and overview of course content

4.1.Overview of a SPD & LPS system

What we need to know about surge and lightning protection from a solar PV from an installation point of view – How to determine when to use surge protection vs lightning protection. During the overview we look at what surges are, where they come from and how equipment could potentially be protected.

  • Sources of surges
  • Why we need SPD’s and what the Standards say.
  • Protection against surges - What are we trying to protect against?
    • Surges caused by direct / indirect events
  • Two types of surge protection systems (Internal & External)
  • Mechanical forces of electrical surges

4.2.SPD requirements according to the Standards

  • SANS10313
  • SANS1042-1 (Lightning Flash Density)
  • SANS60364-7-712
  • Co-ordination

4.3.Inside a Surge arrestor

  • How are SPD’s labelled?
  • How are SPD’s rated? - 8/20 & 10/350 & KA

4.4.Lightning Protection Systems (LPS)

  • The 2 types of LPS (Bonded & Isolated)
  • When to use a LPS system with PV
  • Lightning Flash Density

4.5.Risk Analysis & Risk Calculations

  • Understanding the terminology
  • Understanding the equipment
  • Sources of damage
  • Damage results
  • Risks for the specific source
  • Step and touch potential

4.6.Lightning

  • Understanding lightning in greater detail
  • Formation of lightning
  • Upwards leaders and downward streamers
  • Limit losses

4.7.Lightning Protection Systems

  • Air termination (Rolling sphere, Mesh & Angle of protection method)
  • Down conductors
  • Earth termination (Type A & Type B)

4.8.Bonding vs Earthing

  • What is the difference?
  • Bonding a bonded system

4.9.Electromagnetic Impulses

  • EMP & LEMP (Separation distances)

4.10.Circuit Breakers & Fuses

  • Trip curves
  • Fuses for modules & batteries

4.11.Mounting Structures – General Considerations

  • Ballasted mounting structure
  • Short rail and expansion (Thermal breaks)
  • Mounting Structure Guidelines
  • Dead / wind / hail loads
  • Inspect and Maintain the Mounting Structure
  • Portrait vs Landscape Mounting
  • Clamping Zones
  • Bending Ratios and Radius
  • Do’s and Don’ts for mounting structures

4.12.Mounting Structures - Environmental Conditions

  • Hail Frequency
  • Wind Pressures
  • Terrain
  • Negative & Positive Pressure
  • Uplift and downforce loads
  • Oscillation
  • Lift and drag forces
  • Flat roofs
  • Increased loads near edges / parapet
  • Row shielding

4.13.Regulations and Standards

  • Electrical Installation Regulations
  • Electrical Machinery Regulations
  • NRS097
  • SANS 10142-1-2 – Maintenance

4.14.Registration with the D.o.L.

  • Electrical Tester for single phase
  • Electrical Installation Electrician

4.15.Calculations & Factors

  • Climatic Zones
  • String Calculations
  • Module Coefficients & Factors
  • Load Profiles
  • Conductor Calculations
  • Inverter Sizing (23kW Grid tied System)
  • Storage Calculations
  • Fuse Calculations
