Solar Export Control

Keep Projects Moving Forward

  • Do local regulations limit grid feed-in?
  • Has the utility put a cap on your solar PV plant size?
  • Have local net metering policies recently changed?

Don’t let solar export limitations from the local utility company restrict your plant size. Solar-Log’s grid Feed-in Management provides an innovative solution to significantly minimize losses that result from feed-in caps proposed by grid operators or local regulations. Solar-Log® can throttle exported power from the PV array to meet the specified feed-in cap. Solar-Log’s grid export control functionality means you can still collect RECs and at the same time adhere to the local utility’s required solar feed-in limitation.

+ Solar Export Limiter

Solar-Log® models are flexible to meet the different regulatory and operating requirements from individual countries and grid operators. These solutions allow installers to put up larger solar PV arrays in areas where they otherwise would not be possible and assist in maximizing your solar investment.

Solar Export Control Use Case

This solar PV plant was built in an area that does not allow solar grid export. The solar PV plant is sized to cover a large portion of the building’s consumption when the business is open Monday through Friday. However, the building has very little usage on Saturday and Sunday. Using Solar-Log’s feed-in management, the Solar-Log is able to throttle back the inverters on the weekend. The solar PV plant only produces as much power as the building is consuming. Therefor, the plant owner is able to save electricity costs during the week while still adhering to the grid export limitation on the weekend.

Feed-in Management with the Calculation of Usage

  • Solar-Log® measures building consumption by using a consumption meter
  • Inverters are curtailed to ensure that the power surplus (the difference between the current production and building consumption) does not exceed the maximum feed-in amount defined
  • Solar-Log® is able to control grid feed-in by either a certain percentage of the total inverter power or a specific kW amount.
