Hello, can someone help me configure the Feed-in Concept so that it matches the current principles for calculating the kWh price in Croatia (new rules effective from January 1, 2026)?

According to these rules, if the consumer takes less energy from the grid than they send to it, the price of the exported energy is €0.085/kWh.

If the consumer sends more energy to the grid than they consume from it, then the price of the exported energy is calculated using the formula:

0.085 × (consumed / exported)

Thank you in advance.

Hello,

Thank you for your inquiry.

Unfortunately, the net-billing concept currently in effect in Croatia cannot be modeled in PV*SOL.

As far as we are aware, billing is conducted on a monthly basis. You can create multiple tariffs, but the minimum payment period per tariff is one year. Our development department has been informed that, as of 2026, a minimum payment period of one month is required for Croatia.

If possible, please send us the source of the diagram.

Thank you for your response. Currently in Croatia, under the new regulation, the surplus feed-in billing method is in effect (as I mentioned). The calculation is done on a monthly basis. This means that consumed energy is charged at €0.16/kWh, while the energy sent to the grid is calculated according to the specified formula (the more you send, the lower the price).

I made sketch of diagram. 

I made sketch of diagram. So, there is no solution for new regulation, the surplus feed-in billing method in Croatia?
