Instructions The case study submission can only be made by a provisionally accredited person seeking to upgrade to full accreditation or by a fully accredited person seeking points as part of the CPD program. If you are applying for a Design Only or Design & Install accreditation then your name is the only name that can be present on the circuit design drawings and Performance estimate forms. (Design forms and /or drawings designed by others will not be accepted) If you are applying for any type of Install accreditation you must be the person who undertook the installation (you cannot sub-contract to others) therefore your name shall be the one appearing on all relevant documentation including Installation & Commissioning Sheets. All Photographs, design information and installation & commissioning sheets must be from the same installation. Multiple installation pictures will render the case study void and a new case study will be required. CASE STUDY ASSESSMENT RATINGS Competent / Not-Yet Competent / Fail Competent: An applicant will be deemed competent when the assessor is satisfied that there is sufficient evidence that the installation has been conducted to all current and relevant standards and guidelines and that supporting evidence has been sighted as evidence of this compliance. Not yet Competent : An applicant will be deemed not yet competent when the assessor is not satisfied that there is sufficient evidence that the installation has been conducted to all current and relevant standards and guidelines and that insufficient supporting evidence has been sighted as evidence of this compliance. Failed: An applicant will be deemed failed/ rejected in the following circumstances: The applicant has repeatedly failed to submit the required information A Fail result will require the applicant to make a new submission and additional charges will apply. The Assessor deems that the evidence provided shows a PV installation that may be mechanically or electrically un-safe and may cause physical harm to people or property. The applicant has submitted a false electrical license or is not licensed to carry out the work. The applicant has not met the minimal training standard / completed the necessary training units as required to make the CS application. The assessor deems that the PV installation is in clear breach of AS/NZS 3000 wiring rules.

Accreditation Case Study overview The Accreditation process requires that case studies are submitted when moving from Provisional to Full Accreditation AND when renewing Full Accreditation. This is to ensure compliance with current Australian Standards and that Design/Installation skills are maintained. The power system must: have a minimum rating of 450W PV or 1kWh/day for systems utilising other energy sources have been designed and installed in the previous two years have a load design base on a variable load i.e. not a telecommunications system, battery back-up (UPS) be for a fixed structure i.e. not a mobile structure, boat, caravan, trailer, etc. not have been previously submitted to the CEC for accreditation purposes Case studies should be submitted separately (as the installations are completed) before the due date to enable case study assessors to assist with any non-compliance. Stand-alone power systems (SPS) case studies The AS/NZS 4509.2 Design Guidelines must be used as the basis for all SPS design work. This DOES NOT preclude the use of commercial design software or purpose-built spreadsheets, BUT the designer must be aware of any requirements or recommendations that are not directly addressed by the software used. Additional information is required to cover all aspects of AS/NZS 4509.2 System Design The power system installation must comply in ALL respects to relevant standards, legislation and regulations. Directly applicable standards are: AS/NZS 3000 Wiring Rules AS/NZS 4509.1 SPS Safety and Installations AS/NZS 4509.2 SPS System Design AS 4086 Secondary Batteries for use with SPS installation and maintenance AS/NZS 5033 Installation of photovoltaic (PV) arrays AS 2676 Guide to installation, maintenance of secondary batteries in buildings AS 3011 Electrical Installations Secondary batteries installed in buildings (LV batteries) AS/NZS 3010 Electrical Installations Generating sets NOTES 1. Accredited personnel must be up-to-date and familiar with all Standards and Guidelines. 2. The case study documentation must also include: Case study form/s completed all installed equipment listed System Performance Load Design AS/NZS 4509.2 Section 5 Appendix A major system parameters. This information must be included as part of the design documentation. A copy of the System Commissioning checklist, covering all applicable standards and guidelines should be provided with the case study documentation.

Installation, Testing & Commissioning Sheet General WARNING: Where short circuit currents are required, follow AS/NZS 5033 Appendix D for the steps that shall be undertaken to measure the short circuit current safely. NOTE: Some projects require that short circuit currents are recorded as part of the contractual commissioning; otherwise a record of the actual operating current of each string is sufficient. This could be done by using the meter on the inverter or by using a clamp meter when the system is operational. Testing of the battery load currents could be done by using the meter on the inverter or by using a clamp meter when the system is operational. Insulation resistance measurement WARNING: PV array dc circuits are live during daylight and, unlike a conventional ac circuit, cannot be isolated before performing this test. Follow AS/NZS 5033 Appendix D4 for the steps that shall be undertaken to measure the insulation resistance safely.

Document D-06 Example Wiring Diagram
Document D-07 System Performance Estimate Under the CEC design guidelines the designer has many responsibilities and one of the main responsibilities is in providing: A site specific full system design including all shading issues, orientation and tilt, along with the system s site specific energy yield, including average daily performance estimate in kwh for each month of solar generation. And Ensure array configuration is compatible with the inverter specification. Sources: You can use the detailed formulae available from the CEC design guidelines to help with these design calculations. Alternatively you may use the free online CEC Performance Calculator, available to all currently accredited designers/installers, using your installer login at www.solaraccreditation.com.au There are many commercial tools available to assist in calculating energy yield, for example PV-GC, SunEye, PVSyst, Solar Pathfinder, PV Watts, SolarPlus, etc. Some of these make an allowance for shading. Please note that many inverter manufacturers software will not provide sufficient detail in terms of monthly generation figures. (Install Only Applicants: Please obtain the above information from your system designer) Example of acceptable data from CEC Performance Estimator:
