Google and SolarQuotes 4.9/5. PSW ranking ›
Synergy excludes solar inverter sizes that exceed 5 kW output capacity from the Distributed Energy Buyback Scheme. If feed in tariff is an important factor in going solar, limit inverter selection to 5 kW
For solar only scenarios, 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.
Therefore, 5 kW Inverter capacity (5) ÷ 0.75 = 6.66 kW of solar panels.
PSW Tip: Forget low value Synergy feed-in tariffs. Size a solar energy system better suited your daily energy consumption.
Increase savings potential and improve system efficiency by overdriving your inverter ›
This depends on you. A 6.6 kW solar energy system with a 5 kW inverter will calculate to generate an annual average of 30 units⁴ (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:
6.6 kW = $2290
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 express quote, and we’ll send your complimentary energy yield report.
Perth and Bunbury [region] WA: $38 STC (Small Technology Certificate) value and a 440W solar panel size for multiplication:
- 6.6 kW = $2,088 – 2025 installation
- 6.6 kW = $1,733 – 2026 installation
For your convenience, advertised 6.6 kW solar package prices by Perth Solar Warehouse include the zone 3 STC solar subsidy deducted as a point of sale discount to be redeemed by Perth Solar Warehouse after installation in recovery to the total system cost.

Most residential 6.6 kW solar arrays installed on a 5 kW inverter will qualify for the Synergy solar feed-in tariff named; DEBS (Distributed Energy Buyback Scheme). This means you can receive:
2c ex GST: off-peak
10c ex GST: peak (3 pm to 9 pm)
2024/25 Synergy solar feed-in tariff update ›
As wholesale energy values vary at different times of the day, the Distributed Energy Buyback Scheme values your excess solar energy with the energy available in the grid at a nominated time. A two-cent valuation during higher ambient light periods reflects a surge of wasted solar power to the grid by a high-volume accumulated systems exporting simultaneously.
Solar energy is most valuable when used directly or stored in a battery for later use. If eligible, the Synergy Distributed Energy Buyback Scheme will only favour your energy bill in a reduced capacity.
