Generation guide
Is 30 kW solar ideal for you?
If available rooftop surface area isn’t a concern, it’s essential to choose a solar energy system that matches your daily energy use. A 30 kW solar system is typically appropriate for an average daily consumption of 25 kWh, with a tolerance of up to 5 kWh. This means that if your daily usage is as high as 30 kWh or as low as 20 kWh, a 6.6 kW system could be a suitable option for you. To determine your daily energy consumption in kWh, check your Synergy bill.
Additional expansion factors should also be considered. If you need less or more power, explore 19 kW or 39 kW solar options x PSW.

Customers should always obtain site-specific average generation report. To obtain this, contact sales support.
Select an inverter.
An inverter converts solar energy into usable energy. When installed without batteries, network and oversizing limits often restrain a 30 kW solar package to a 5 kW inverter output. Here are three of our most popular 5 kW hybrid inverters:
Goodwe
+$2190*
Model: EH 5.0. A hybrid inverter that suits 1-phase power supplies and has a 5 kW maximum power output. Three-phase variations are available at an additional cost. Non-activated hybrid.
Sigenergy
+$3490*
Model: Sigen EC SP 5.0. A hybrid inverter/battery controller suited to 1-phase power supplies and a 5 kW maximum power output requirement. Three-phase variations are available at an additional cost.
Fronius
+$3090*
Model: Fronius Primo GEN24 5.0. A hybrid inverter suited to 1-phase power supplies and a 5 kW maximum power output requirement. Three-phase variations are available at an additional cost. Non-activated hybrid.
Consider a battery?
Some customers are content with a solar-only solution, and we support that. With state and federal battery rebate options, home solar batteries are more affordable than ever.
Battery options.
If required, select a battery to suit your 30 kW solar system. Ideally, an option that stores 5 to 25 kWh daily for evening energy offset. Selected batteries offer blackout protection. Here are three of 2025’s most popular batteries:
Powerwall
+$11,290*
Model: 13.5k kWh, Powerwall 3. No inverter required. An all-in-one battery system with gateway that ideally suits 1-phase power supplies and has a 5-10 kW maximum power output. Three-phase power supply compatible, net metered.
Goodwe
+$5,390*
Model: 16 kWh, Lynx Home F G2. A high-voltage DC-coupled battery compatible with Goodwe EH & ET model inverters.

Sigenergy
+$10,190*
Model: 30 kWh, Sigen Battery module combination. A low-voltage DC-coupled battery compatible with Sigen Energy Controller.

Storage guide
Do you need a battery?
If you consume all of your power during the day, a battery will be less of a consideration. However, if 50% of energy consumption or more is unavoidably evening consumption, a battery completes the likelihood of bill reduction success.
But size matters! For example, a Tesla Powerwall provides 30 kW of storage capacity, approximately half of a 30 kW solar energy system’s daily generation (30 kW = approximately 30 kWh per day).
Your ideal battery size, more often than not, depends on your evening power use.

Charge your car.
Charge your electric vehicle from the sun with 30 kW solar x PSW. Solar-optimised EV chargers can ramp up and down the charge rate to use only excess solar energy that would otherwise be exported to the grid.

EV charge guide
Solar power your electric vehicle
One of the greatest variables is how much charge will your electric vehicle require per day to be powered by the sun effectively.
A recent internal study found a moderate daily commute required approximately 10 units per day. Topping this up daily from the sun in smaller fractions has benefits such as lower energy costs (considering both petrol and grid electricity resources).
In this graph, the EV charge guide (10 kWh) is added to the sum of the Powerwall storage guide (13.5 kWh).

Frequent Questions.
Familiarise yourself with common 30 kW solar questions.
In certain instances, yes. An advertised 30 kW solar package price has a base installation and product combination criteria.
1. Structure: The listed prices refer to single-level, three-phase and single-roof face dwellings with adequate switchboard accessibility/provisions available to accommodate the additional circuitry or associated components.
2. Product/ package: The base nominated price uses an SAJ R5 (10 kW) inverter within PSW Installation Zone 1 after the STC Zone 3 subsidy has been deducted as a point-of-sale discount. Additional installation costs may apply to ensure this package meets your specific expectation.
For the 2024 calendar year, eligible Perth and Bunbury region customers within STC Zone 3 receive a $4852 point-of-sale discount (subsidy) when installing 30 kW of solar panels on a 10 kW inverter. An amount that reduces annually.
Based on 128 Small Technology Certificates, a system incorporating 30 x 440 W solar panels and a $38 STC market value.
128 STC’s x $38 value = $4852 subsidy.
For your convenience, the PSW Energy 24 kW solar package prices include the subsidy already deducted as a point of sale discount (redeemable by PSW Energy after installation).
*Conditions:
2. Structure. The listed prices refer to single-level, single-roof-face (solar panels), non-detached dwellings with adequate switchboard accessibility and provisions available to accommodate the additional circuitry and/or associated metering.
3. Base installation criteria: Solar Panels. For eligible prices, the base package must have an accompanying CEC-approved inverter or integrated storage system. The advertised price is after the [Zone 3] STC rebate has been deducted as a point-of-sale discount. Additional installation costs ›
6. WA Battery Rebate. The value of the Residential Battery Scheme is applied as a $130 per kWh point-of-sale discount up to 10 kWh (usable kWhs) of storage capacity, with a requirement to join the Synergy or Plico VPP. Customers can opt out of this rebate and add the value to the advertised battery price.
7. National Battery Rebate. The National Battery Booster Program’s value is applied as a point-of-sale discount valued at $38 per certificate after trading fees. Request a preliminary quote for the total system cost (including GST) and incorporated pricing for the itemised rebate.
