If you're a family in Western Australia considering solar energy or adding a battery to reduce your power bills, one of your primary concerns might be: "Can I trust this installer to do the job correctly and be available for support in the future?"
The 2025 Solar Nerds Solaris Awards provide an independent, data-driven method to help you evaluate that decision. In their WA Awards Edition, PSW (Perth Solar Warehouse and PSW Energy) received a high ranking in implementation volume.
Top 2: 2nd in Western Australia for home battery installations: 10,398 kWh across 673 installs
Top 5: 4th in Western Australia for total solar installed (systems up to 100kW): 6,128 kW across 724 installs
Solar Nerds’ rankings are built from Clean Energy Regulator REC Registry data (the national certificates created for eligible solar and battery installs). In plain terms: it’s based on real installation activity, not marketing claims. Their WA Awards Edition also notes the figures are estimates derived from registry data, and that recorded dates can lag/shift because STC registrations don’t always match the exact install date.
Why PSW’s result is reassuring for homeowners
- It demonstrates scale—hundreds of households in Western Australia have chosen PSW. With 724 solar installations and 673 battery installations completed in a single year, this is a strong indication of consistent performance. It’s not just a one-time spike; there’s a steady output across homes week after week.
- It showcases proven battery capability, where system design and commissioning quality are crucial. PSW ranked second statewide for battery volume, installing 10,398 kWh across 673 systems. This averages to about 15.5 kWh per battery installation, which aligns with the "whole-home evening coverage" that many families aim for.
- It reflects that you are dealing with an installer operating in a mature and competitive market. In 2025, Western Australia added 269,913 kW of solar power across 30,678 systems and 339,587 kWh of battery capacity across 19,192 systems, indicating there is no shortage of options. In such a crowded market, a top-tier ranking helps distinguish installers with a proven track record from those still trying to establish themselves.
What does this mean in a decision
If your goal is lower bills and less dependence on the grid, PSW’s Solar Nerds recognition translates to a few practical advantages:
• Peace of mind: independent verification that PSW is doing meaningful volume in WA—not just a handful of jobs.
• Better “right-sizing”: experience across hundreds of homes improves the odds your system is sized to your household usage (not overpromised, not underspecified).
• One team for solar + battery: the report shows PSW is installing solar and batteries at similar scale, which matters because the best results come from designing them as one system
If you’re considering solar or a battery in 2026, bring a recent power bill (or two) and tell us what matters most—lowest bills, backup power, EV-readiness, or a blend. We’ll recommend a system size that fits your home and your goals, and we’ll explain the “why” in plain language.
