Adjust the sliders to match your home. We'll estimate your annual bill savings, export income and self-sufficiency — based on real North West solar yields. It's an instant guide; your free survey gives the exact numbers.
Estimate only — costs vary by property. Your free, no-obligation survey gives the exact figures and payback for your home.
What your panels would generate each month against what your home uses. Hover or tap a month for the detail.
We assume around 900 kWh generated per year for every kW of panels — a realistic figure for Lancashire and the wider North West, with cloud and seasonal variation already factored in. A 4 kW system works out at roughly 3,600 kWh a year.
Solar saves you most when you use power as it's generated. We model a typical household demand curve — lower overnight, higher in the morning and evening — so the split between electricity used at home and exported reflects real life.
Adding a battery stores surplus daytime generation instead of exporting it, then powers your home through the expensive evening peak — pushing the share of solar you actually use up sharply. Many customers also charge the battery on cheap overnight rates for extra savings.
Defaults use a typical import rate of 24p/kWh and a 15p/kWh Smart Export Guarantee rate, but you can change both under "Advanced" to match your own tariff. MCS-certified installs mean domestic solar is zero-rated for VAT.
