System sizing and self-consumption

[Anders]

Can PV Sol calculate what size system would best match a consumption pattern if, for example, you want a self-consumption rate of 80%?

I have attached a project where I am trying to determine how many panels and what size inverter would be optimal for this setup if the customer wants a self-consumption share of 80%. At the moment, I am basically just testing different configurations.

Another question regarding this project: you can see that I have installed batteries—5 units of 5.12 kWh each. This results in a self-consumption rate of 66.4%.

Has AI control for charging and discharging the batteries been included in the calculation? With AI control, wouldn’t the self-consumption rate be expected to increase further?

Dear Anders,

Thank you for your inquiry and for sharing the project file.

Unfortunately, it's not possible to determine the number of PV modules based on a predefined self-consumption rate. We recommend switching from 3D planning to 2D planning. There, you can quickly simulate different system sizes by entering the new number of modules and test whether the desired self-consumption rate is achieved. In your case, a self-consumption rate of 80 percent is achieved with 24 PV modules. (Please ensure you have selected the appropriate battery system. The S6-EH3P10K-LV-ND-H + Pylon-Tech Force H3 (25.6 kWh) battery system is compatible with the S6-EH3P10K-LV-ND-H PV inverter.)

Currently, AI control for battery charging and discharging is not included in the calculation. We will forward your suggestion to our development team.

Please find enclosed the project file we have edited.

Okay. Thank you. How do I contact the development team?
