Make data-driven decisions about solar, battery storage, and electricity tariffs
Using real consumption data or synthetic load profiles, you can evaluate modeled scenarios for investment, self-sufficiency, and electricity costs. This shows which configuration ranks best among the tested variants for your goals.
Plan PV & battery storageWhich PV and battery sizes fit your household? Compare modeled yield, self-consumption, and economics before investing.Add battery storageWhich battery size fits your existing PV system? Compare modeled savings, self-sufficiency, and payback using your consumption.Compare electricity tariffsCompare fixed and dynamic electricity tariffs using your consumption profile and historical prices from a selected reference year.
Choose your data basis
Every analysis is based on an energy profile. You can upload consumption, PV, and battery data as CSV or create a synthetic profile from location, household, and system details.
Plan
PV & battery storage
Compare PV and storage combinations using your consumption, budget, and selected objective.
- Compare modeled self-sufficiency and returns
- Put savings based on your consumption profile into context
- Understand the economics and payback of the tested variants

Beta version: feedback welcome
Voltary is still in beta. Some bugs, unexpected visual issues, or occasional delays may occur. Because our calculations are computationally intensive, things can take a little longer, especially when demand is high. Your feedback helps us keep developing Voltary in a focused way.
