Solar used at home reduces electricity imports. Exported solar earns the entered export rate; it does not reduce household demand. Heat-pump electricity is included in the upgraded figures.

This explorer is an annual energy-balance model with illustrative starting values. The starting home has no existing solar, battery, or heat pump. Enter your own consumption, tariffs, and upgrade costs to explore a scenario.

Annual saving = current bill − upgraded net bill
Simple payback = installed cost ÷ annual saving
Net result after N years = N × annual saving − installed cost

This is not a quote, an eligibility check, or a building assessment. Default prices and reduction percentages are illustrative, not verified local data. Installation suitability, ventilation requirements, climate, shading, cooling changes, and occupant behaviour are not assessed. Projections exclude finance, grants, maintenance, replacement, degradation, inflation, and discounting. Use professional assessment and local quotes before committing to work.
