Understanding the Tesla Installer Performance Score (TIPS)

Tesla Installer Performance Score Logo on a black background

Tesla has launched the Tesla Installer Performance Score (TIPS), a new, data-driven framework aimed at assessing and acknowledging the technical excellence and customer satisfaction of its installation partners. For certified technicians and installers, this system offers a clear perspective on how installation quality and customer experience can be translated into measurable performance.

TIPS is more than just a score; it serves as a collaborative framework for achieving mutual success. It helps Tesla and its partners align around consistent standards of quality, reliability, and customer satisfaction.

Contents

The Tesla Installer Performance Score (TIPS) is a comprehensive measurement system that combines technical metrics and customer feedback to produce a single, objective performance score. It represents an evolution of Tesla’s earlier Pro Score program, integrating lessons learned to offer a more balanced and transparent approach.

Purpose of TIPS:

How the Score Works

Step 1: The Installer Score

Each installer’s score is calculated based on four key metrics, weighted to reflect their importance in overall quality:

Metric
Weight
Description
Installer Certification
22.5%
Completion and passing of the Powerwall 3 Final Exam in Tesla Workforce Management.
Device Commissioning Tests
26.25%
Successful completion of Backup, Internet, and Metering tests within 48 hours of commissioning.
Device Diagnostics
26.25%
Absence of post-installation errors such as negative load, solar disconnection, or wiring issues.
Customer Activation
25%
Timely registration of the system to the customer’s account and app login within 7 days.

Each technician’s weighted average contributes to the overall company score, with more installs giving proportionally greater impact.

Step 2: The Company Score

The Company Score is a weighted combination of:

  • Installer Average (80%) — reflecting overall technical excellence.

  • Customer Satisfaction (20%) — based on post-installation survey results converted to a 100-point scale.

This approach ensures a balance between technical performance and customer experience — rewarding both precision and professionalism

The Five Core Metrics Explained

  • Installer Certification:
    Confirms that each installer has passed the required Powerwall 3 competency exam. This ensures technical readiness and contributes to a perfect score on this metric.

  • Device Commissioning Tests:
    Measures success in system setup and commissioning. Passing the Backup, Internet, and Metering tests within 48 hours ensures reliability from day one.

  • Device Diagnostics:
    Tracks early system performance to identify issues like negative loads or Powerwall disconnections during the first operational week.

  • Customer Activation:
    Evaluates how smoothly the system is transferred to the homeowner. Key indicators include timely registration and the customer’s first app login.

  • Customer Satisfaction:
    Based on customer survey feedback collected 30 days post-commissioning. Reflects the overall experience across sales, installation, and aftercare

Implementation Timeline & ACCESS

  • October 2025: Initial communications and training resources.

  • Late 2025: Access to score previews and installer dashboards.

  • Q1 2026: Official launch of the TIPS program across all accredited partners

The early announcement gives teams more than 90 days to familiarise themselves with the new metrics and prepare before the system goes live. Initially, installers will receive performance insights through their Tesla Account Managers, who will share dashboards and score breakdowns during regular reviews.

Later in the rollout:

Partner Portal: A new dashboard will offer real-time access to company-wide and installer-level scores.

Tesla One App: Individual installers will be able to view their own performance metrics directly in the app

Support and Resources

Training and Certification: Available through Tesla Workforce Management.

Technical Documentation: Found in the Partner Portal and Energy Library.

Tesla Installer Performance Score: Quick Reference Guide (official)

Dedicated Support: Email questions to [email protected], copying your Account Manager on all inquiries

The Tesla Installer Performance Score (TIPS) is an important development aimed at aligning installation standards with Tesla’s commitment to quality and customer satisfaction. While there is no immediate action required, understanding how this system functions will help accredited technicians and installers prepare for its official launch in early 2026.

TIPS serves as a partnership tool—it measures excellence, recognises achievements, and ensures that every installation meets the high quality that Tesla customers expect.

2026 Operational Objectives & Target Plan — Internal Briefing

Introduction — strategic context for 2026

Reference: PSW-PLN-HSEQ-02 (Version 2, 05/11/2025).

This briefing outlines the operational objectives and targeted plan detailed in PSW-PLN-HSEQ-02, presenting a clear roadmap for our department for 2026. The plan is centred on five strategic pillars that collectively promote sustainable growth.

Contents

Each pillar includes specific targets, ownership details, and action steps to ensure measurement and accountability through July 2026, which is the document’s deadline. The targets are based on evidence and address recognised challenges, including cost drivers (such as rework and incidents), revenue enhancers (like customer satisfaction and throughput), regulatory risks (compliance), and the need for long-term operational resilience (via renewable energy and a strong Integrated Management System).

Below, we present each operational objective along with its measurable target, the key performance indicators (KPIs) for monitoring progress, the required data and reporting frequency, the assigned ownership, and the rationale for prioritising each objective.

Monitoring, Reporting & Accountability

Governance: Management is explicitly identified as the lead for the majority of blue-highlighted, management-monitored items in the plan. The document sets July 2026 as the reporting horizon for these objectives.

Cadence: Monthly operational reviews should include KPI dashboards covering: client satisfaction, profitability, rework rate, incident reporting compliance, inspection completions, environmental incidents, renewable generation %, audit adherence, and action-closure rate. Quarterly reviews supplement monthly reporting with deeper trend analysis (e.g., RCA trends, energy performance).

Escalation: Triggers for escalation should be defined at the KPI level (examples): rework rate >10% for two consecutive months; incident reporting compliance <100% in any month; action closure rate <80% for two consecutive months. Escalations should route to Management with clear corrective action plans and deadlines.

Data-driven justification (summary)

Quality & Profitability: Targets (90% client satisfaction; +$[x] profitability; <10% rework) are interdependent — improving quality (lower rework) and throughput increases margins and customer lifetime value.

Safety & Compliance: Achieving 100% reporting within 24 hours, quarterly inspections, and 100% legal compliance reduces risk (injury, fines, shutdowns) that materially affect costs and reputation.

Environment & Resilience: A 70% self-generated energy target and zero environmental incidents lower long-term operating cost and signal sustainability leadership to customers and partners.

System Discipline: Targets for audit adherence and timeous action closure, maintain controls, and make improvement efforts reliable and measurable.

Next steps for Department Heads

To translate these targets into operational plans, department heads should deliver the following by July 2026 (consistent with the plan):

  1. Confirm ownership & lead contacts for each KPI listed above in your area (single point of accountability).
  2. Establish or validate measurement baselines (e.g., jobs per installer, current rework rate, and current percentage of self-generated energy) and submit the baseline data to Management for consolidation.
  3. Produce a 90-day implementation plan that describes how your team will achieve assigned actions (training schedule, inspection calendar, audit slots, toolbox talks, energy projects, RCA processes).
  4. Define report formats and cadence for your team’s KPIs (to align with the monthly operational review). Provide a sample KPI dashboard.
  5. Identify resource gaps (training, tools, metering, personnel) and submit requests by the next monthly management meeting so resourcing can be prioritised.
  6. Implement corrective actions and escalation procedures aligned with the triggers noted above, ensuring timely closure and evidence capture for audit purposes.

Closing — organisational commitment

The 2026 operational plan for McKercher Corporation and PSW establishes clear and measurable targets in key areas, including quality, safety, compliance, sustainability, and the effectiveness of management systems. Specific objectives include achieving a 90% client satisfaction rate, increasing profitability by an additional $[x], reducing rework to less than 10%, ensuring zero environmental incidents, and generating 70% of energy from renewable sources. This level of specificity enables each department to align its activities with measurable outcomes. Management will monitor these key items and conduct monthly reviews to track progress, identify barriers, and allocate resources as needed. Department heads should use this briefing to finalise baselines, assign accountability, and begin executing the outlined action plans.

Important Notice: Sigenergy Recall (8, 10, 12 kW) Single-Phase Controllers

Affected Sigen Energy Controller highlighted represented the affected component from the Sigenergy recall in Australia 2025

Sigenergy Technology Co., Ltd. has issued a voluntary recall of certain single-phase Energy Controllers (8 kW, 10 kW, 12 kW) and SigenStor EC inverters that were sold throughout Australia. This decision follows the product change notice issued in October 2025 and demonstrates Sigenergy’s commitment to working with the ACCC, Clean Energy Council, and Clean Energy Regulator to ensure the highest standards of safety and performance.

Contents

What's Happening

Sigenergy has identified that some AC plugs on earlier single-phase inverter models may be susceptible to damage if installation procedures were not followed precisely.
Although the products themselves meet all design and safety standards, improper cable termination during installation can cause overheating at the AC connection under high load.

To address this, Sigenergy has:

  • Introduced a new, ferrule-free AC plug design,
  • Issued a firmware update adding real-time monitoring and automatic power adjustment under sustained load, and
  • Launched a nationwide replacement program for all affected units.

Are My Products Affected?

Models included in this voluntary recall:

  • SigenStor EC 8.0 SP / 10.0 SP / 12.0 SP
  • Sigen Hybrid 8.0 SP / 10.0 SP / 12.0 SP

No three-phase models are affected.
Units with the green-dot label on packaging already feature the updated AC plug and are not subject to recall.

What Customers Should Do?

If you’ve already received a firmware update notification, your system is operating under enhanced safety parameters until your replacement is scheduled.

For InstallerS

  • Do not install or recommission any affected single-phase units.
  • Register replacements through Sigenergy’s national service portal.
  • A $500 service subsidy applies to approved replacements.

Ongoing Commitment

McKercher Corporation subsidiaries and Sigenergy are working closely with Australian regulators to ensure all affected units are replaced promptly and transparently. The voluntary Sigenergy recall underscores our shared commitment to safety, quality, and customer trust.

Update: Falls Emergency Rescue Plan (PSW-PLN-HSEQ-0X)

Department: HSEQ — Health, Safety, Environment & Quality
Document: FALLS EMERGENCY RESCUE PLAN — PSW-PLN-HSEQ-0X
Document (site copy): Falls_emergency_rescue_plan.docx (internal Drive)

This is an official notification to all technical staff regarding the Falls Emergency Rescue Plan (PSW-PLN-HSEQ-0X). The plan has been issued and updated, and it is now the company standard for responding to falls from heights.

Contents

What this update is about

This is an official notification to all technical staff that the Falls Emergency Rescue Plan PSW-PLN-HSEQ-0X has been issued/updated and is now the company standard for responding to falls from height. The plan establishes the required procedures, responsibilities and equipment for safe rescue of personnel suspended in fall arrest systems, and must be used at every site where work at heights (>2 m) is undertaken.

Why this matters

The Plan sets mandatory controls to protect both the injured worker and rescue personnel — including pre-planning, site-specific rescue plans, competence requirements, and emergency response steps. Following the Plan reduces the risk of suspension trauma and other fall-related injuries, ensuring rescues are performed safely and in compliance with our HSEQ obligations.

Summary — purpose, scope & key procedures

Purpose & scope: Defines rescue requirements for falls of two (2) metres and above and requires inclusion of the Plan in risk assessments and SWMS for any applicable work.

Key procedures:

  • Rescue options include self-rescue, assisted self-rescue, mechanically aided rescue, aerial work platform/crane-assisted rescue, and team rescue; all must be pre-planned for the site conditions. 
  • Responsibilities for organisation, rescue personnel and supervisors, plus inspection, assembly and maintenance of rescue equipment. 

 

How it protects personnel: Pre-planning, competent trained rescuers, prescribed equipment, and rehearsal of emergency procedures minimise time suspended, control suspension-trauma risk, and protect rescue teams.

Updated Hammer Drill Operation Procedures – Mandatory PPE & Safe Work Practices

Effective Immediately – Compliance required across all McKercher Corporation sites.

McKercher Corporation has updated its Hammer Drill Operation Procedures to strengthen worker safety, eliminate preventable injuries, and ensure full compliance with AS/NZS safety standards. All team members operating hammer drills must follow these updated procedures and mandatory PPE requirements without exception.

Contents

Why These Updates Matter

Using a hammer drill exposes workers to various hazards, including high-speed debris, excessive noise, and airborne dust, all of which can lead to serious injuries and long-term health problems. These updates aim to:

Your safety, and that of your team, depends on strict adherence to these standards.

Mandatory PPE Requirements

All workers using a hammer drill must wear the following Personal Protective Equipment (PPE). Each item is required for compliance with site and regulatory safety standards.

PPE Item
Purpose / Hazard Mitigated
Safety Glasses (AS/NZS 1337.1:2010)
Protects against high-velocity debris. Sunglasses are not an acceptable substitute.
Hearing Protection (Earplugs or Earmuffs)
Prevents hearing damage from prolonged exposure to high noise levels.
Dust Mask or Respirator
Protects against dust inhalation and respiratory irritation, especially in enclosed or dusty environments.
Gloves
Reduces vibration-related strain and protects hands from abrasion.
High-Visibility Clothing
Ensures visibility to surrounding workers and machinery operators.
Steel-Toe Boots
Protects feet from dropped tools, falling debris, and impact hazards.
Long-Sleeved Shirts and Trousers
Shields skin from dust, debris, and minor abrasions.

Why Sunglasses Are Not Sufficient

  • They do not provide impact resistance against flying debris.
  • They lack side shields, leaving eyes exposed.
  • They do not meet AS/NZS 1337.1:2010 standards for industrial eye protection.

Only certified safety glasses are permitted for hammer drill operations.

Safe Work Practices

Adhering to PPE requirements is only part of safe operation. Every worker must also follow these essential safe work practices:

  • Pre-Work Inspections

    • Inspect all tools and PPE for damage before use.

    • Verify that cords, plugs, and drill bits are intact and secure.

  • Work Area Safety

    • Maintain a clean, organized workspace free of tripping hazards.

    • Keep bystanders clear of the drilling zone.

  • Proper Tool Handling

    • Use the correct drill bit for the material.

    • Do not force the tool; let the hammer action perform the work.

    • Maintain a firm, balanced stance during operation.

  • Breaks & Ergonomics

    • Take regular breaks to minimize fatigue and vibration exposure.

    • Adjust grip and posture to reduce strain on wrists, shoulders, and back.

  • Dust and Ventilation Control

    • Use dust extraction systems or wet drilling where possible.

    • Ensure adequate ventilation when operating indoors.

Compliance Expectations

Effective immediately, all hammer drill operations must comply with the updated personal protective equipment (PPE) and procedural standards. Supervisors are responsible for ensuring compliance. Failure to follow these safety requirements may result in disciplinary action and could lead to removal from site duties.

Safety is Everyone’s Responsibility

Every preventable injury impacts our team’s safety record and the well-being of our people. These updates go beyond compliance; they focus on ensuring everyone returns home safely at the end of each shift.
