Sunnix Transparency

Saved data

• Precise geographic coordinates (latitude and longitude) are those you select on the map, or those automatically returned by the geocoding system starting from the entered address
• Session type (simulation or configuration)
• Whether you are using the Google Solar API or not
• Session status (created or completed)
• ID of the associated simulation or configuration (if completed)

Retention period

Sessions are kept for a maximum of 30 days, then automatically deleted

Example

If you enter an address, Sunnix shows you the map. You click the correct roof (if not already selected), and the precise coordinates of that point are saved (e.g., latitude 45.071, longitude 7.686). These coordinates remain only in the session logs and are deleted after 30 days

Saved data

• Entered address
• Precise geographic coordinates of the point selected on the map (same as the session)
• Maximum desired power for the system to simulate (kWp) and actual simulated power
• Chosen panel (generic, from a partner company, or custom)
• Estimated annual and monthly production (kWh)
• Total number of panels and occupied area
• Total cost of panels (if calculated, depends on whether the price per watt for the panel is present)
• Creation date
• Accuracy of the estimate: year-on-year standard deviation of production, irradiation on the module plane and the breakdown of losses, as PVGIS returns them
• Other data present in the summary are automatically calculated by the page, but are not saved

Retention period

Simulations are kept for 48 hours, then automatically deleted.

Example

If you perform a simulation for a 3kWp system on your roof, Sunnix saves the estimated production data and the chosen power. After 2 days, the simulation is automatically deleted.

Saved data

• Entered address
• Precise geographic coordinates of the point selected on the map (same as the session)
• Maximum desired power for the system to simulate (kWp) and actual simulated power
• Chosen panel (generic, from a partner company, or custom)
• Data of the created pitches (surface area, tilt, orientation)
• Estimated annual and monthly production (kWh)
• Total number of panels and occupied area
• Total cost of panels (if calculated, depends on whether the price per watt for the panel is present)
• Creation date
• Accuracy of the estimate: year-on-year standard deviation of production, irradiation on the module plane and the breakdown of losses, aggregated across the roof surfaces
• Other data present in the summary are automatically calculated by the page, but are not saved

Retention period

Configurations are kept for 48 hours, then automatically deleted

Example

If you configure a 4 kWp system with a certain type of panels and add battery storage in the summary, Sunnix saves the configuration data but not the storage. If you send a contact request, the storage is included only in that single request

How it works

• Sunnix saves a snapshot of your simulation or configuration (with the reference to the simulation or configuration and any extras filled out in the summary)
• The request goes to the Sunnix team
• If an available partner company exists, the request is forwarded to them. In any case, your data is never shared with others without your consent.

Saved data

• Account email address (stored encrypted with AES-256-GCM)
• Geographic coordinates of the system (latitude and longitude)
• Total system power (kWp), number of panels, panel type and inverter
• Characteristics of each roof slope (orientation, tilt, power, mounting type)
• Energy price entered for savings calculation (€/kWh)
• Daily simulation logs: date, estimated production (kWh), estimated savings (€), weather conditions, full result (hourly curve, model breakdown)
• Digital twin calibration factors by type of day (clear, mixed, overcast) — computed automatically by the system

How it works

• Create an account with your email and register your system with location, power, and roof slope characteristics
• Upload your production history (CSV from your inverter portal) to calibrate the model — or enter data day by day
• Every day Sunnix simulates expected production using real weather data (irradiance, temperature, cloud cover) and compares it with your data
• If an anomaly is detected, the system identifies the probable cause and calculates the economic loss. You can delete your account at any time.

Retention period

System data, simulation logs, and calibration are kept for the duration of the active subscription. After cancellation, data is maintained read-only until the paid period expires, then deleted within 30 days.

Example

You register a 6 kWp south-facing system in Milan. You upload last year's CSV history from your inverter portal. Sunnix calibrates the digital twin on your real data and, from that point on, compares expected production with actual production every day. If on a full-sun day the system produces 30% less than expected, Sunnix flags the anomaly, the probable cause (e.g. dirty panels), and the economic loss.

Here are all the average cost items on Sunnix

How it works

• In that case, we only save your email, the subscription date, and your status (subscribed, unsubscribed)
• It is used exclusively to send you updates about Sunnix
• You can unsubscribe at any time using the link at the bottom of every email sent by Sunnix

What is sent to Google Gemini

• Chosen panel: name, power and efficiency
• System power in kWp and number of modules
• Estimated annual production and the summer/winter split
• Orientation and tilt of the roof surfaces you drew
• Storage capacity, if you added one

What is not sent

Address, coordinates, email and anything else that could point back to you: they are not in the text we send.

Why we keep it

Google's answer is cached and indexed on the coordinates, so a second visit to the same building does not trigger the request again. It is data about the building, not about you: it contains nothing personal.

What is stored

• One record per simulated day: expected production, real production if you reported it, the weather used, any anomaly and its probable cause
• The plant's three calibration factors — sunny, mixed, cloudy — updated at every real reading
• The plant diary: the entries you write (cleaning, maintenance, faults, free notes) with date and optional cost
• The checks you declare you have done after a day flagged as anomalous
• The API keys you generate so an external system can report production: of each we keep only the cryptographic fingerprint, never the key itself

Email

The report arrives every day, every Monday or never: you choose from the plant preferences, and every email carries the link to turn it off. Turning it off stops the sending only — the simulation continues and the records stay.

It is like this with Sunnix, because:

• We never ask for more data than necessary to provide you with the service
• We never sell your data to third parties
• We never use your data for targeted advertising
• We never save data beyond the necessary time
