Five per cent of all Solar Homes Program installations are audited every year as part of our commitment to safety and quality, and to ensure installations comply with the latest standards (see Audits).

Independent auditors use this checklist when they conduct audit inspections of solar hot water and hot water heat pump installations under our program:
They look at the safety and quality of hot water installations and determine where opportunities for improvement need to be followed up with the authorised retailer.
Analysis of these audits led to Solar Victoria commissioning guidance to help installers comply with all relevant industry standards and regulations when installing solar hot water and heat pump systems under our program.
