Make data-driven decisions about solar, battery storage, and electricity tariffs
Compare the costs and savings of different PV and battery sizes and see which electricity tariff suits your business. Use your own load profile or a reference profile.
Plan
PV & battery storage
Compare PV and battery combinations based on your business consumption, budget and chosen goal.
- Compare upfront costs with ongoing savings
- Compare self-consumption, grid imports and demand charges across system sizes
- Calculate when the investment pays back under your chosen assumptions

Add
battery storage
Compare battery capacities and power ratings using your load profile and chosen goal. The simulation evaluates battery operation for reducing demand peaks.
- Calculate the effects on demand peaks and demand charges
- Compare upfront costs and savings for each battery size
- Calculate when adding storage pays back under your chosen assumptions

Compare
electricity tariffs
Compare fixed and dynamic electricity tariffs using your load profile and historical prices. Both totals include the complete annual electricity bill, excluding VAT.
- Compare quarter-hourly consumption with historical market prices
- Compare annual costs including network charges, taxes and levies
- See which tariff would have been cheaper in the reference year
