Which system would you like to analyse?

Choose your existing system. Next, we assess whether adding storage is worthwhile.

OR
Why does the system type matter?

Your choice determines the technical limits, rules and comparison options used in your calculation.

  • Technology: Inverters limit usable power. For balcony PV, we also distinguish between AC and DC storage connections.
  • Rules: Plug-in solar devices can qualify for simplified procedures under certain conditions. A small regular PV system is not automatically balcony PV.
  • Economics: The balcony-PV path assumes no feed-in remuneration and a compatible consumption sensor for storage.

Our comparison: The balcony-PV path covers only this device, with no additional regular PV or existing storage. This choice does not replace checks of connection, registration or device compatibility. Federal Network Agency guidance

Analyze your existing solar system and consumption patterns, then compare battery configurations using your selected objective

OR
Why We Need Your Consumption Data

Battery sizing is highly dependent on your specific energy usage patterns. With your real data, we can:

  • Compare battery capacities for your needs and selected objective
  • Simulate your self-sufficiency rate with different battery sizes
  • Compare modeled financial returns using your actual consumption
  • Compare the economics of different battery configurations

Data Privacy: Your upload is transferred between your browser and our platform over encrypted HTTPS and processed on our servers in the EU in a session-bound workflow. Your uploaded file is stored only temporarily for technical processing and is deleted automatically afterwards.

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.
