ClearCents provides no warranties and makes no representation that the information provided is appropriate for your particular circumstances or indicates you should follow a particular course of action.
  • System Performance Factors: Estimated utility bill reductions are simulated using fixed historical efficiency brackets based on setup tiering, ranging from a 50% bill drop for a basic 6.6kW solar array up to a 96% offset for a 13.2kW solar system combined with a 40kWh battery storage configuration.
  • Government Incentives & Rebates: Federal rebates combine estimated Small-scale Technology Certificates (STCs) alongside current tiered battery incentive allocations. State rebates are applied natively based on localized criteria, including the Western Australian Synergy Residential Battery Scheme capped strictly at a maximum of $1,300 for qualified configurations.
  • Static Pricing Metrics: Energy consumption values, regional network supply charges, and your base quarterly electricity bill are assumed to remain completely static across the entire 10-year timeline. Calculations do not account for compounding utility grid inflation, energy retail price hikes, or alterations to solar Feed-in Tariffs (FiT).
  • Linear Payback & Maintenance: The return-on-investment timeline relies on a simple linear formula (Net Installation Cost divided by Annualized Bill Savings). Projections assume flawless system uptime and omit hardware degradation over time, battery capacity fade, inverter replacement costs, or routine system maintenance fees.
