How we calculate, match, and maintain transparency

Market Data & Consumer Protection Analysis

Beyond calculator tools, this platform provides objective market intelligence derived from public government sources to help consumers identify risks in the battery market.

Data Sources (All Public Records)

-Clean Energy Council (CEC): Official registry of approved products including approval and expiry dates
-ACCC Product Safety: Recalls, safety notices, and consumer protection enforcement
-ASIC Business Registry: ABN verification, insolvency notices, director information
-Court Records: Class actions, bankruptcy proceedings, commercial disputes
-Synergy SSL: WA rebate qualification and VPP eligibility

Market Maturity Scoring Methodology

Each manufacturer receives a Market Maturity Score (0-100 points) based on six objective, publicly verifiable factors:

30 pts

Market Tenure

Years on CEC registry

20 pts

Market Stability

Product listing velocity

20 pts

Track Record

Installation history

15 pts

Product Range

CEC-approved models

15 pts

Local Presence

AU office & warranty

Penalty

Negative Events

Recalls, safety incidents

Cross-Product Solar History Bonus

Manufacturers with established history making other solar products (inverters, panels) receive a bonus within the Market Tenure category, recognising their broader industry experience:

-+10 pts: Both inverter and panel manufacturing history (3+ years each)
-+8 pts: Inverter manufacturing history only (3+ years)
-+5 pts: Panel manufacturing history only (3+ years)

This bonus is capped at the Market Tenure category maximum of 30 points.

Transparency Note

Market Maturity Scores reflect a manufacturer's observable presence and tenure in the Australian market. They are not product quality judgments, performance ratings, or purchase recommendations. A lower score may simply indicate a newer market entrant, not an inferior product.

What We Do NOT Do

- Provide subjective opinions, product ratings, or endorsements
- Make quality assessments or performance predictions
- Use proprietary or non-public data sources
- Accept payments or sponsorships from manufacturers

Calculator Assumptions

DEBS Export Rates	10c/kWh (3-9pm), 2c/kWh other times, max 50 kWh/day
A1 Retail Tariff	~32.37 c/kWh (Synergy, effective 1 Jul 2025)
Federal STCs	8.4 STCs/kWh at ~$39.9 each (Jan-Apr 2026), capacity taper from May 2026
WA Rebate	$$130/kWh up to $$1,300 via Synergy (10kWh max eligible); interest-free loan up to $10,000 for eligible households
VPP Credits	Conservative estimates based on 20-30 events/year
Efficiency	Battery-specific round-trip (typically 89-95%)

Results are illustrative and depend on your actual usage patterns, solar generation, and future tariff changes. We do not guarantee payback periods or savings amounts.

Installer Matching Criteria
