| Solar Victoria Approved | Solar Victoria requires its approved installers to meet strict quality and safety standards before lodging PV rebate or battery loan applications on a homeowner’s behalf. |
| SAA Certified Installers | SAA certification verifies that every installer on site holds the required Australian electrical licences and has been independently audited for workmanship quality and safety compliance. |
| VEU Approved Provider | VEU accreditation allows GES to offer eligible households additional discounts on heat pumps and hot water systems alongside the solar installation. |
| CEC Accredited Designer | Every GES system is designed by a Clean Energy Council accredited professional, ensuring layout, component selection, and inverter sizing meet Australian standards and maximise output. |
