PROJECT LCP Solar
Design areas included:
• Irradiance calculations
• Module layout design
• Inverter room layout design
• Design of inverter and charge controller mounting framework
• AC and DC electrical design and calculations
• AC main cable design
The Certificate of Compliance( CoC) and its test report required substantial effort, especially after the withdrawal of SANS 10142-1-2, which was initially introduced to expand on the SANS 10142-1 standard for low-voltage electrical systems and included a test report for PV systems. However, due to issues with the standard, it was withdrawn shortly after its release. This left the industry without an official PV test report, and many companies resorted to creating their own.
Before this project, LCP Solar developed a comprehensive PV test report from scratch, investing over 100 hours refining and expanding it. This report is now used on our projects and will serve as a reference for future inspections. As a result, we are recognised as an authority on this subject.
For safety and quality reasons, the property’ s main kiosk supply breakers and secondary distribution board, initially out of scope, were rewired, and new switchgear was installed.
