6.65kW Solar And 40kWh Battery System Installation in Point Cook Home
For this Point Cook homeowner, the objective was to build a more efficient and energy-independent home by combining 6.65kW solar PV system with substantial 40kWh battery storage, with an estimated annual solar production of 8,534kWh.
This system is expected to deliver approximately $1,159.53 in annual energy savings. Eligible solar and battery STCs provide $7,550 in government incentives, helping reduce the overall upfront investment while improving the home’s long-term energy solutions.
Solar & Battery System Specifications — Point Cook Installation
Our SSA-certified installation team designed and installed an integrated solar and battery system combining 14 solar panels with a GoodWe inverter and battery technology. The system is grid-connected, allowing the home to generate, store and use renewable energy efficiently while reducing reliance on grid electricity.
| Installation Details | Specification |
| Solar Panels | Trina Solar TSM-475NEG9RH.28 |
| Solar Capacity | 14 Panels | 6.65kW Total Capacity |

Save $7,550 With Eligible Solar & Battery Government Incentives
Government incentives played an important role in reducing the upfront cost of this solar and battery installation. Most importantly, rebate eligibility and incentive values vary by system, property and applicable program requirements, so homeowners should have their eligibility assessed individually rather than assuming the same incentive amount; however, in this case the total rebates are
| Government Rebates | |
|---|---|
| 39 STCs 7 × $38.00 | −$1,482.00 |
| 164 Battery STCs 7, 8 × $37.00 | −$6,068.00 |
| Total Rebates | $7,550.00 |
The system is estimated to produce 8,534 kWh annually, with projected energy savings of approximately $1,159.53 per year.
Point Cook Solar Installation: Switchboard, Isolation & Safety Compliance Done Right
The electrical work included a complete switchboard upgrade to safely integrate the new solar and battery system. A dedicated Clipsal enclosure was installed with clearly labelled circuits for PV, PV DP (DC isolation), and ES (battery energy storage), along with EV-ready provisions for future charger integration.
The main distribution board was upgraded with new circuit breakers, isolators and compliant solar and battery warning signage. A secondary sub-board was also installed with dedicated battery isolation switches and system labeling. The meter box was upgraded with a digital smart meter to support accurate solar export and energy consumption monitoring, delivering a compliant, inspection-ready installation.
