Calculate how much electricity you will consume right away (in sunny weather) and how much you will put into the grid and use it during the dark hours of the day. 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%).
In Lithuania, the installation or purchase of a one - kilowatt solar power plant in a solar park costs about EUR.
