Why 13 kW solar on an 10 kW inverter?
Western Power may restrict inverter capacity in certain network locations to no more than 10 kW inverter output capacity.
Most leading inverter brands state that their inverters can endure solar array oversizing by up to 50%. The Clean Energy Regulator has had its say on this topic and capped the oversizing of solar inverters to 33% without a battery.
10 kW Inverter capacity (10) ÷ 0.75 = 13.33 kW of solar panels.

How much will I save from 10 kW of solar panels?
This depends on you. A 13 kW solar energy system with a 10 kW inverter will generate an annual daily average of 60 units⁸ (kWh).
Maximum energy saving: The ability to shift appliance operation in line with solar production, consuming only the variable system energy yield. Considering a Northern roof aspect (0°) with a 25° roof pitch, located in Perth (6000) and environmentally derated to 70% generation at Standard Test Conditions, your energy savings on the Synergy Home Plan A1 tariff in 2025 at 30c per kWh would calculate to:
13 kW = $4599
Suppose you choose to opt out of a battery. In that case, these savings reflect unobstructed daylight hours within a variable solar bell curve period, 8 am to 5 pm, and are presented as unit-for-unit savings.
It’s important to note that every installation is unique and requires a location-specific energy yield report for informed decision-making. We’ve made getting your free yield report easy. Request a hassle-free quote, and we’ll send your complimentary energy yield report.
How much is the rebate for 13 kW of solar panels in Perth, Western Australia?
Perth and Bunbury [region] WA: $38 STC (Small Technology Certificate) value and a 475W solar panel size for multiplication:
System sizes | Installation year | Rebate value |
|---|---|---|
13.3 kW | 2025 | $4,191 |
13.3 kW | 2026 | $3,492 |
For your convenience, advertised 13 kW solar package prices by Perth Solar Warehouse include the zone 3 STC solar rebate deducted as a point of sale discount to be redeemed by Perth Solar Warehouse after installation, recovering the total system value.

Do I still receive a feed-in tariff from Synergy with 13 kW of solar panels?
Systems greater than 5kW inverter capacity are exempt from the Synergy Distributed Energy Buyback Scheme (DEBS). Here’s PSW’s guide to navigating the Synergy solar feed-in-tariff with ease: Read More ›
Feed-in tariff or none, solar energy is most valuable when used directly or stored in a battery for later use. Consider a battery and ensure your new energy saving appliance does the whole job.
Can I increase my solar array size beyond 13 kW on an 10 kW inverter if I add a battery?
Yes. However, this more likely depends on your available rooftop surface area and ideal product combination.
Different inverter/all-in-on battery specifications range in maximum inverter over-driving capabilities. To increase your energy yield from solar, seek out a quote by Perth Solar Warehouse to understand the maximum solar array/inverter/battery combination to suit you.
*Pricing & installation conditions:
1. Advertised prices and rebates. Displayed prices apply to the product shown on this page and are subject to eligibility for applicable rebates. Solar PV pricing assumes eligibility for Small-scale Technology Certificates (STCs). Battery pricing assumes eligibility for the WA Residential Battery Scheme (if applicable) and/or the federal Cheaper Home Batteries Program. Unless stated otherwise, prices are based on an Eligible Structure and Base Installation Criteria. Prices include GST and are shown with eligible rebates applied as point-of-sale discounts (where specified). Additional installation costs may apply; see “Additional installation costs”.
2. Eligible Structure. Displayed pricing assumes a simplified residential installation: single-storey, single-roof face for solar panel arrays (where applicable), and a non-detached dwelling with suitable access and existing switchboard capacity/provisions to accommodate required additional circuitry and/or metering.
3. Base Installation Criteria – Solar PV. Base-package solar PV pricing assumes the PV system is installed with a CEC-approved inverter (or an integrated storage system that includes an eligible inverter). Where stated as “post-STC,” the displayed price includes a point-of-sale discount based on the Zone 3 STC value. Additional installation costs may apply.
4. Base Installation Criteria – Inverter/Battery. Base-package pricing assumes the primary inverter and/or primary (AC-coupled) battery is installed within 15 metres of the main electrical switchboard. Expansion (DC-coupled) batteries must be vertically integrated with the primary unit or installed within 3 metres of the primary battery/inverter (as applicable). Additional installation costs may apply.
5. Small-scale Technology Certificates (STCs). Where STCs are included, the STC value is applied as a point-of-sale discount calculated at $38 per certificate from the GST-inclusive total. Displayed prices that reference STCs are shown after this STC discount.
6. WA Residential Battery Scheme (WA Battery Rebate). Where applicable, the WA rebate is applied as a point-of-sale discount, calculated at $130 per usable kWh, up to a maximum of 10 kWh of usable capacity. Participation requirements include joining an eligible Virtual Power Plant (VPP), such as Synergy or Plico (as applicable). Customers may choose to opt out of the WA Residential Battery Scheme (where permitted), in which case the battery price will increase by the amount of the rebate.
7. Cheaper Home Batteries Program (Federal Battery Rebate). Where included, the value of any national battery incentive is applied as a point-of-sale discount calculated at $38 per certificate (net of trading fees). Because eligibility and net value can vary, request a preliminary quote for the full GST-inclusive system cost and the itemised incentive value applied to your configuration.
8. Performance and generation estimates. Any generation figures shown are indicative only and do not represent guaranteed output. Site-specific modelling is recommended; contact Sales Support for an estimate based on your address and roof design.
