Certification: 2026, Perth Solar Warehouse ›
Origins
Certified installer to strategic partner. Perth Solar Warehouse entered the Tesla Energy Certified Installer network in 2019. The early years (2020–2021) established operational foundations: training, compliance, and product familiarisation within Tesla’s structured onboarding framework.
By 2022, Tesla elevated Perth Solar Warehouse to Premium Certified Installer status, a distinction awarded to the top 5% of Tesla’s certified installer network in Australia. Premium Certified status introduced mandatory project-level auditing, where every installation is documented and remotely assessed against Tesla’s internal quality benchmarks. In 2023, Perth Solar Warehouse scored 95% across all jobs assessed under this framework.
The distinction matters. Standard certified installers are authorised to sell and install Tesla products. Premium Certified Installers operate under continuous performance monitoring, maintain access to priority product allocation, and are positioned by Tesla as its most trusted brand partners. There are currently only four Tesla Premium Certified Powerwall Installers in Western Australia. PSW Energy, Perth Solar Warehouse is one of them.
Premium Certified status earned and retained
Tesla reassesses Premium Certified status annually. It is never guaranteed, regardless of prior performance. PSW Energy, Perth Solar Warehouse must consistently demonstrate alignment across five criteria:
- Exceptional installation quality — Every installation is submitted for Tesla's remote assessment and ranked against standardised benchmarks, creating an ongoing quality scorecard that directly informs certification decisions.
- Deep product knowledge — Staff maintain current proficiency across the full Tesla Energy product suite (Powerwall 3, Gateway, Wall Connector, Tesla app ecosystem). Training requirements evolve with each product release.
- Distinguished customer experience — Tesla independently monitors customer satisfaction. Perth Solar Warehouse has maintained a 4.8 out of 5 rating across Tesla's internal audit process, assessed beyond the point of sale through the full lifecycle from consultation to aftercare.
- Longevity and depth of relationship — Seven years of collaboration and five consecutive years at Premium Certified level represent sustained bilateral investment, not short-term performance spikes.
- Alignment with Tesla's mission — Tesla's mission to accelerate the world's transition to sustainable energy is directly paralleled by McKercher Corporation's focus on improving sustainable energy adoption through digitalisation and customer-centric implementation.

Staff Takeaway
The Tesla Energy relationship touches every department involved in Tesla product delivery. Sales and administration teams operate within Tesla’s Partner Portal and maintain the product knowledge standards Tesla audits. Applications and projects teams manage documentation and submission workflows feeding Tesla’s remote assessment process. Installation teams follow Tesla’s protocols, with every job contributing to the quality scorecard. Aftercare teams manage the post-installation experience that Tesla independently monitors.
The 4.8/5 satisfaction rating, 95% audit scores, and five consecutive years of Premium Certified recognition are collective achievements — the direct output of every team within Perth Solar Warehouse contributing to a standard Tesla reassesses annually.
As McKercher Corporation Director Derek McKercher noted: “A direct relationship over an enduring period has allowed PSW to assist Tesla’s mission towards broader adoption of sustainable energy products for more. Customers prefer fewer layers of complexity, especially where warranty concerns arise.”
What this means for customers
For homeowners engaging Perth Solar Warehouse for Tesla products, Premium Certified status provides specific assurances:
- Manufacturer-backed quality verification: Every Tesla installation undergoes Tesla's internal auditing process. Standard certified installers are not held to this standard.
- Enhanced warranty confidence: Tesla product warranties require installations to meet Tesla's strict standards. Premium Certified Installers operate under the highest level of manufacturer-verified compliance.
- Priority product access: Perth Solar Warehouse receives priority allocation for new Tesla products. This is how the team received the first Powerwall 3 in Western Australia and represented at the national launch.
- Local expertise with manufacturer alignment: Seven years of Tesla Energy experience combined with detailed understanding of Western Australian energy regulations, Western Power grid requirements, and state-specific compliance.
- Continuity and accountability: Backed by McKercher Corporation's 20-year business history in energy services, Perth Solar Warehouse offers long-term local presence that extends support well beyond the point of sale.
The year ahead
The partnership enters 2026 with established momentum. The relationship has evolved from a standard commercial arrangement into a strategic collaboration defined by co-hosted events, shared performance metrics, product launch participation, and mutual investment in customer outcomes.
McKercher Corporation views this partnership as a model for how manufacturer–installer relationships should function: built on transparency, sustained performance, and a shared commitment to enabling broader energy independence for Australian households.
