CPCPPS5023 — Design solar water heating systems

1 Evaluate design

• 1.1Establish scope of work for solar water heating system design using codes, plans, specifications manufacturer requirements and client brief.
• 1.2Assess locations of solar collectors and evaluate effect of each location on efficiency.
• 1.3Analyse and identify statutory and regulatory requirements and relevant Australian Standards and codes for the design of solar water heating systems.
• 1.4Establish performance requirements considering safety of system users or building occupants.
• 1.5Evaluate environmental and community benefits of solar water heating systems.
• 1.6Apply sustainability principles and concepts as part of the design process.
• 1.7Conduct research including a desktop study to outline design parameters.
• 1.8Determine factors that contribute to quality, safety and time efficiency.
• 1.9Conduct cost-benefit analysis to compare a range of materials and system designs.

2 Plan and detail system components.

• 2.1Plan layout of pipework systems including type and location of fittings and valves.
• 2.2Select and evaluate the configuration and application of a range of proprietary solar heated water systems, materials and valves.
• 2.3Perform calculations for solar water heating systems.
• 2.4Plan and detail typical configuration of a hydraulic circuit (flow and return) and its components for a pumped-storage solar water heating system.
• 2.5Specify water quality and water pre-treatment methods.
• 2.6Specify suitable types and levels of insulation for system components and detail a range of methods to protect from freezing and over performance.
• 2.7Calculate pipe size, velocity, flow and pressure for a range of applications.
• 2.8Plan pipe supports for a range of applications.
• 2.9Specify approved materials, jointing methods and installation requirements.
• 2.10Provide allowance for expansion and contraction.

3 Design and size systems.

• 3.1Select solar collectors to meet identified installation requirements.
• 3.2Design and size solar water heating, solar pre-heat and solar pool and spa heating systems to meet requirements.
• 3.3Consider legionella bacteria mitigation design principles in the design of solar water heating systems.

4 Prepare documentation.

• 4.1Prepare a return client brief for the preferred design.
• 4.2Prepare plans and specifications for solar water heating systems.
• 4.3Prepare testing and commissioning schedule.
• 4.4Produce operation and maintenance manual.

What does an assessment tool for CPCPPS5023 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPCPPS5023 needs to address all 45 unit components: 4 elements with 26 performance criteria, 7 performance evidence requirements, 12 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for CPCPPS5023?

Auditori pulls the current release of CPCPPS5023 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for CPCPPS5023 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPCPPS5023 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of CPCPPS5023, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
