Estimated solar production with weather

Hello everybody,
I would like to know the estimated production of the photovoltaic system in the next few days based on the weather, I saw that Forecast uses the weather forecast only for a fee. Are there any free alternatives?
It would be enough for me to know the expected daylight hours, I tried Accuweather but, if Iā€™m not mistaken, it only provides the daylight hours of the day itself.
Thank you so much for the advice :slight_smile:

Have you seen this?

Forecast.solar, as mentioned by Hellis, works fine.
See this pic, white line is the forecast. It also creates some useful sensors.
