You’ve decided on a Tesla Powerwall, or you’re seriously considering one. Now comes the part that’s harder to research: who should install it?
It’s a fair question. There are many quality solar and battery installers in Perth, and most of them will tell you they can install a Powerwall. The good news is that Tesla has built a certification framework that makes it easier to compare. Every Tesla Certified Installer in Australia has met Tesla’s training and compliance requirements, which means choosing any certified installer gives you a solid foundation of product knowledge and installation capability.
Within that network, Tesla recognises a smaller group as Premium Certified Installers, the top 5% of the certified installer base. Perth Solar Warehouse is one of them, and has been for five consecutive years.
We’re proud of that. But this post isn’t just about us; it’s designed to help you understand Tesla’s certification levels, what to look for when comparing installers, and how to make the most informed decision for your home. PSW certificate 2026 ›

Tesla’s Certified Installer program exists to ensure that homeowners receive a consistent standard of product knowledge, installation quality, and aftercare, regardless of which installer they choose. Every Tesla Certified Installer in Australia has completed Tesla’s training requirements and is authorised to sell and install Tesla Energy products. That’s a meaningful baseline, and it means that choosing any Tesla Certified Installer puts you in good hands relative to the broader market.
Within that network, Tesla recognises a smaller group as Premium Certified Installers, the top 5% of the certified installer base. Premium Certified status introduces a higher level of ongoing accountability, including mandatory project-level auditing where every installation is documented and submitted to Tesla for remote quality assessment. Tesla reviews the work against their internal benchmarks and scores each project. This auditing cycle is continuous and forms part of an annual reassessment that determines whether the Premium designation is retained.
It’s important to note: Premium Certified status is never guaranteed year to year. It reflects current performance, not past reputation. Achieving it five times in a row means Perth Solar Warehouse has met Tesla’s highest standard across five independent assessment periods.
Perth Solar Warehouse celebrates all businesses that hold Tesla Premium Certified Installer status as quality ambassadors of Tesla Energy products. Achieving and maintaining this recognition is of an elite calibre, and every Premium Certified Installer in Australia contributes to raising the standard of sustainable energy implementation for homeowners nationally. The stronger the Premium Certified network, the better the outcomes for customers everywhere.

When you choose any Tesla Certified Installer, you’re choosing quality. When you choose a Premium Certified Installer, you’re adding a layer of manufacturer-verified assurance. Here’s what that translates to:
Your warranty is protected by verified installation quality.
Tesla’s product warranty requires installations to meet the manufacturer’s specific standards. Premium Certified Installers operate under Tesla’s own auditing process, which independently verifies that installation quality meets those standards on every project. In 2023, Perth Solar Warehouse scored 95% across all Tesla-assessed installations.
Your system is designed for local conditions.
Our team designs Tesla systems optimised for the greater Perth region of Western Australia, factoring in your roof orientation, household energy profile, Western Power grid requirements, and Synergy tariff structure. Seven years of Tesla Energy collaboration in this region have given us a deep understanding of the local nuances that affect system performance and compliance.
You benefit from priority product access.
Premium Certified Installers receive priority access to new products and updates from Tesla. That’s how Perth Solar Warehouse was the first in Western Australia to receive the Tesla Powerwall 3 in September 2024, and among the top 2% of Australian installers invited to represent at the national Powerwall 3 launch in Sydney.
Your experience is independently monitored.
Tesla tracks customer satisfaction for its Premium Certified partners through their own post-installation assessment process. Perth Solar Warehouse has maintained a 4.8 out of 5 rating under this framework.
Your support is long-term.
Perth Solar Warehouse, as part of McKercher Corporation, has been in the energy business for over 20 years. Our southern suburbs showroom is at 3/90 Discovery Drive, Bibra Lake, WA. Our northern suburbs showroom is at 1/42 Pinnacle Drive, Neerabup, WA.

One of the strengths of Tesla’s certification program is the transparency it provides to homeowners. Understanding how Tesla monitors its installers can help you ask better questions when comparing quotes, with PSW or with any Tesla installer.
- Installation auditing. For Premium Certified Installers, Tesla requires documentation of all critical installation points. Tesla remotely assesses each installation and scores it against standardised benchmarks. This process creates an ongoing quality record that directly informs certification decisions.
- Customer satisfaction tracking. Tesla independently monitors the customer experience for its certified partners, not just at the point of sale but throughout the journey, including aftercare. This data feeds into the annual Premium Certified reassessment.
- Performance reviews. Tesla issues periodic performance reports to its certified installers covering sales performance, customer satisfaction, and installation quality. These reports provide measurable, comparable data. Perth Solar Warehouse's Q4 2023 performance review identified 362% year-on-year growth in Powerwall installations, earning the Tesla Energy Performance Excellence Award, one of three awarded nationally that quarter.
- Ongoing training requirements. Tesla's training framework evolves with each product release. Installers must maintain current proficiency across the full Tesla Energy product suite. For Powerwall 3, for example, installers must pass the Powerwall 3 Exam for Installers with a score of 80% or higher before they can install and commission the product.
If you’re comparing Tesla installers, we’d encourage you to ask any certified installer about these metrics. A good Tesla Powerwall installer, Premium Certified or otherwise, will be happy to share their performance data with you. Informed customers make better decisions, and better decisions lead to better outcomes along your sustainable energy journey.
Western Australia has a strong network of Tesla Certified Installers, and Perth homeowners are the beneficiaries. When multiple installers operate within a quality-certified framework, standards rise across the board.
If you’re evaluating your options, a few things are worth noting.
1.
Certification consistency.
There’s a meaningful difference between Tesla Certified and Premium Certified, and within the Premium tier, consecutive years matter. Sustained performance across multiple assessment cycles tells a different story from a single strong period.
2.
Tesla-specific experience.
The Tesla Energy ecosystem, Powerwall 3, Gateway, and Wall Connector, has its own design logic, commissioning requirements, and software integration. An installer who works across the full suite will approach your system differently.
3.
The longer view.
A Powerwall carries a substantial warranty period. The installer you choose today is the one you’ll rely on for aftercare and support years from now. Local presence and business longevity are worth weighing alongside price.
4.
Pricing transparency.
An itemised quote that shows exactly what you’re paying for, including additional installation costs, is something any quality Tesla installer should provide without hesitation.
We welcome the opportunity to be part of your research and encourage you to speak with other Tesla Certified Installers in the Perth region as well. Informed customers make confident decisions, and that’s good for the entire industry.
