How TrySolar models electricity plan results

TrySolar provides indicative modelling only. The dashboard turns your plan rates and household assumptions into estimates so you can compare scenarios, not guaranteed savings or advice.

Purpose

TrySolar helps New Zealand households model how electricity plans may perform against their usage, solar, battery, EV, and location settings. It is designed to make plan trade-offs easier to see before you enter your own bill or provider rates.

Data sources

The example provider presets are based on publicly available plan information and reasonable assumptions. Many rates depend on your address, meter, region, or eligibility, so presets are not a live price-comparison service.

Calculation methodology

The app models monthly energy use, seasonal solar output, how much solar you use directly, battery storage, EV charging, export earnings, free-power windows, fixed daily charges, and location adjustments. Results are projected over a year from the plan and settings you choose.

Known limitations

TrySolar does not confirm eligibility, current retailer pricing, discount rules, meter setup, installer design, shading, hardware performance, plan availability, or tax treatment. Actual costs and solar or battery performance can be quite different from the estimates shown.

Provider non-affiliation

TrySolar is not an electricity retailer and is not affiliated with the providers represented in example presets. Rankings are based on modelled results from the rates and assumptions in the app, not paid placement.

Disclaimer

TrySolar provides estimates only. Results are based on the rates, usage, solar output, battery, EV, location, and pricing settings entered into the app. Electricity prices, export rates, eligibility, discounts, GST, meter setup, and retailer terms can change. Solar and battery performance varies by site, hardware, weather, shading, orientation, installer design, and household behaviour. TrySolar is not financial, legal, tax, engineering, electrical, or retailer advice. Check rates and settings with your provider, installer, or qualified adviser before switching plans or purchasing equipment.

Limitations to check

  • Provider rates and export earnings can change after a preset is reviewed.
  • Exact rates often require your address, meter number, or an eligibility check from the provider.
  • Solar output depends on site design, weather, shading, orientation, losses, and household behaviour.
  • Battery and EV results depend on charging patterns, usable capacity, charging and discharging losses, and the settings you choose.
