Proven. Local.
Nothing short of brilliant. Quoted a very reasonable price for a solar system and the guys were efficient and informative when they installed it. Perth Solar Warehouse did all the liasing with Synergy to make sure our connection ran smoothly, I didn't have to do much of anything. They also communicated with me very well, so impressed. We are building a new house now and I will certainly look to them to install solar there.
Leanne Ziarkievicz - Google ⭐⭐⭐⭐⭐
We had a solar system installed in December 2022. It has generated over excessive energy every day, except on partly cloudy days, when it generated around a fraction less. We are extremely happy with our solar power system choice. Perth Solar Warehouse were very transparent and extremely helpful and patient with us while we were deciding on the best option for our needs. They gave us a range of systems to choose from. The installation was done very carefully and professionally. I would highly recommend them for solar power systems.

After extensive research, we decided to go with Perth Solar Warehouse. Their pricing is competitive and represents great value for money. The entire process was seamless, transparent and professional. From the initial quote, countless questions which they were more than happy to answer all the way through to installation.
Their in-house installers Joel and Dan were efficient and friendly and did a great job cleaning up after the installation. Highly recommended!

Why 32 kW of solar panels on an 24 kW inverter?
Western Power may limit inverter capacity in certain network locations to no more than 24 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.
24 kW Inverter capacity (24) ÷ 0.75 = 32 kW of solar panels.

How much will I save from 30 kW of solar panels?
This depends on you. A 32 kW solar energy system with an 24 kW inverter will generate an annual daily average of 135 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:
30 kW = $10,347
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 30 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:
- 31.825 kW = $10,028 – 2025 installation
- 31.825 kW = $8,357 – 2026 installation
For your convenience, advertised 30 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 30 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 32 kW on an 24 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.
