Analyse Energy Costs and Solar Savings Together

The electricity bill and the solar installer quote sit in different spreadsheets, and most homeowners never connect them properly. Working out the real financial case for solar — or for shifting consumption to off-peak hours — requires combining two data sources that are rarely seen together.

Using both electricity_prices and solar_estimate together lets you model what your bill would look like under different scenarios: solar only, battery storage, time-of-use shifting, or a combination. You can calculate exactly how much of your solar generation you would self-consume versus export, and what each scenario saves against today's tariff.

Energy-conscious homeowners building the business case for investment, housing associations modelling whole-estate energy upgrades, and financial advisers helping clients evaluate green energy decisions all use this combined approach to get to a number they can act on.
