Perth Solar Warehouse, the residential solar subsidiary of McKercher Corporation Pty Ltd, received four awards at the 2026 SunWiz Awards, presented at the Smart Energy Conference in Sydney in May 2026. The results are compiled independently by SunWiz from installation volumes and verified customer review data across the 2025 calendar year.
The Four AwardS
- ESS Top 5 WA: one of Western Australia's five highest-volume battery storage installers
- PV Top 5 WA: one of the state's five highest-volume solar PV installers
- Most Popular #2 WA: ranked on verified customer review volume and rating across major platforms
- #1 Local Solar Hero, Perth South West: the highest residential installation volume in the region for 2025. This is the second consecutive year Perth Solar Warehouse has held the result.
How the results are determined
SunWiz is an independent Australian solar market analyst. The annual awards draw on installation data and verified customer reviews rather than self-description.
The Most Popular category applies the strictest filter. Only companies with 50 or more verified reviews averaging 4.8 stars or higher are eligible, and by SunWiz’s published methodology that threshold alone places the eligible field within the top 2.5% of solar businesses in Australia. Perth Solar Warehouse ranked second in Western Australia against that field.
Interpretation for our customers
Customers researching the company behind Perth Solar Warehouse can read the four results as independent measures rather than marketing claims. Volume rankings indicate scale. Review rankings indicate how that scale is delivered.
The Local Solar Hero result is the most local of the four: more households in Perth South West chose Perth Solar Warehouse than any other installer in 2025, in the region the company serves from its Bibra Lake base. Perth Solar Warehouse was established in 2013 and is part of a business that has operated in Western Australian electrification since 2004.
Recognition of the team
Awards of this kind are earned at the level of individual installations. Every system counted in the 2025 data was designed, installed, and supported by McKercher Corporation staff working from the Bibra Lake and Neerabup bases: installation crews, system designers, service technicians, and the office team that coordinates each job.
The same applies to the review data. An average of 4.8 stars or higher across more than 50 verified reviews is the cumulative record of how individual customers were treated, one installation at a time. The company has acknowledged both groups: the customers who chose Perth Solar Warehouse in 2025, and the employees whose work the awards measure.
Group context
McKercher Corporation Pty Ltd is the Western Australian clean energy group behind Perth Solar Warehouse and PSW Energy. The group is Bureau Veritas Certified ISO 9001/14001/45001 and holds WA Electrical Contractor Licence EC010771.
