This ratio is usually around 60/40 (percent). If you consume a lot of electricity during the day (bright) - then you can enter 70-80 percent. If you consume little during the day and consume more in the evening, then your answer could be 20% or 30%. The more electricity you use at home during the daylight hours, the less you will pay for storage. The current storage rate of 1 kWh is EUR (from January 1st 2022). 1 kWh storage rate is EUR + value added tax (VAT = 21%).
