Frequently asked questions
How accurate are the production forecasts?
Forecasts combine live weather and irradiance data (Open-Meteo), long-term climate averages (NASA POWER) and PV modelling (PVGIS, Forecast.Solar), tuned to your panel tilt, azimuth and type. They are planning estimates — actual production also depends on equipment condition, shading and soiling. See our Terms for details.
Does the app work without an account?
Yes. There is no account system at all. Your installations and production records are stored only on your device. See the Privacy Policy.
How do I manage or cancel my Premium subscription?
Subscriptions are handled by Apple. Open Settings → your Apple ID → Subscriptions on your iPhone, select Helios Premium, and manage or cancel there. Cancelling at least 24 hours before the renewal date prevents the next charge.
How do I restore my purchase on a new device?
Open the app, go to the Premium screen and tap Restore Purchases. Make sure you are signed in with the same Apple ID used for the original purchase.
The widget shows no data — what should I do?
Open the app once so it can refresh and share data with the widget. If it persists, remove the widget from your home screen and add it again.
How do I delete all my data?
In the app, go to Settings → Data & Privacy → Delete All Data. Because nothing is stored on our servers, this removes everything. Deleting the app has the same effect.
Which languages are supported? / Hangi diller destekleniyor?
English, Türkçe, Deutsch, Français, Español, Italiano, Português (BR), हिन्दी, العربية and English (UK). The app follows your device language.
