## Usage You could use the app to switch on electric appliances or charge a car or battery based on the forecast solar power, to maximize self-consumption. You can compare the daily forecast with your actual production. The app uses 2 providers: Solcast and Forecast.Solar ## Solcast registration Sign up your solar installation at [Solcast Toolkit](https://toolkit.solcast.com.au/live-forecast) You have to setup the 'Free' Home PV owner account (hobbyist) which gives you (currently) 50 API calls a day.
