increase own consumption


Recommended Posts

Hi Rakeshevergen,

the own consumption is the result of the interaction between the energy production of the PV system and the energy consumption of the consumers. It cannot therefore be adjusted, so that it is 25%, for example.

If the PV system produces 10000 kWh per year, for example, and you have a consumption of 2500 kWh, this would represent 25% of consumption over the year. But it is not said that the PV system can cover the load at all times. The simultaneity and the performance profiles of PV and load are decisive factors here. The time step of the simulation also has a considerable influence on the own consumption.

It is best to select a few load profiles, and vary the annual energy consumption and then simulate this. You will see how your own consumption changes in the results.

If you PV energy generation is 589 342 kWh, it won't be possible to achieve an own consumption of 480 000 kWh. This would mean a own consumption ratio of over 80%. Even with battery storage it is unlikely to get such a high ratio. But it really all depends on the load profile that you have. If all the energy is consumed during day time it might be possible.

If you need more support, let me know. Kind regards,
