Adjust the assumptions and see how the indicative results respond. This is an educational calculator, not a quotation or guarantee.
All fields are editable. Estimates update instantly. Import and export rates are examples; enter your actual tariff rates.
Model assumptions: 950 kWh per kWp for an unshaded south-facing reference system, adjusted by your roof selections; simplified annual self-consumption estimate. No battery degradation, standing charges, installation costs, export eligibility or half-hourly usage profile modelled. Not a substitute for a professional design.
Solar generation is measured in kWh. The financial benefit depends on how much you use at home, what you avoid buying from the grid and any eligible export payments.
Battery storage can shift some solar electricity to later hours. Actual value depends on charging patterns, usable capacity, round-trip losses, consumption and tariffs.
Two roofs with the same panel count can generate different amounts because of direction, tilt, shading and local conditions.
Access, scaffolding, electrical work, inverter choice, battery size and network requirements all affect a final quotation.
