SunTally
Your inverter shows production. SolarSelf shows the money.
Self-consumption %, feed-in value and payback for your solar.
Why SunTally exists
Inverter and balcony-PV apps show how much you produced but never the economics — how much you actually saved, your self-consumption rate, or your payback. SolarSelf models your tariff and feed-in rate to answer those questions, all on-device.
What SunTally does
- System profile: PV peak, install cost, feed-in and grid tariffs
- Log production, consumption and self-consumed kWh per day or month
- Self-consumption %, self-sufficiency %, € saved and simple payback
- "Add a battery?" what-if with revised payback estimate
- Optional local inverter / Home Assistant LAN read (off by default)
- CSV import for production and consumption data
- Export everything to CSV or JSON
- Fully offline — no account, no subscription

Privacy and local storage
SolarSelf keeps all energy data on your device. Consumption patterns can be sensitive, so nothing is uploaded. The optional inverter/HA read stays on your own LAN; no telemetry, no account.
