To whom it may concern,

How to have situation where the surplus of PV energy does not go to the grid, but the loads are connected to the grid to be fed by the grid when there is no PV output?

Best regards,

Hi Faruk,

in order to avoid grid feed in you can set the maximum power clipping to 0%:

Hope that helps, kind regards,

Hi Martin,

Thank You for the information.

Hi,

When setting maximum power clipping to 0% for the case Faruk described (surplus of PV energy does not go to the grid, but the loads are connected to the grid to be fed by the grid when there is no PV output), which "Energy Balance/Feed-in Concept" should we use? Surplus Feed-in or Netmetering?

I understand from an economic point of view that this should not be too important, but maybe there's a diference for the program?

 

Could you advise?

 

Thank you,

Hi aponsa,

the decision which economic concept you must apply does not depend on the feed-in clipping. It does depend on your local tariff. In Germany for example with have surplus feed-in tariffs. In other countries like Brazil or Poland, net metering tariffs prevail.

Kind regards,

How to input tariff right. 

Have such a situation: I have price of energy I buy from the grid (0,15eur/kWh) Also I can save my power "in the grid" when sun is shining and plant producing more than needed and return kWh when is needed (night time or winter) for 0,05eur/kWh. Also I sell the annual rest to the grid provider for the fixed price (0,04eur/kWh). 

I use the "Net-Metering" method. Also fulfilling "Net-Metering tariffs" with "Tariff period 1" "Energy price" 0,15, "Compensation for Surplus" 0,04 with "annual accounting". And the question is how I need to enter a tariff for my saved and after returned power???

Thanks for your support.
