Feature request: Solar Power support

Hi,

thanks for developing this app! I love it and use it regularly 😀

Since I started using the app, I got solar panels. It seems that the app doesn't take this into account when calculating the "money saved by hourly rate".
Today, for example, the price during the night is very low, and significantly higher during the day. So it pays off to sell by hourly rate to Tibber. But it doesn't show up in the off peak app.

Best regards, Lennart
