With Photovoltaic (PV) curtailment we deliberate scaling back or halting of solar power generation below what the PV system could otherwise produce — even though sunlight is available. In effect, some of the solar energy that could be harvested is left unused, because injecting it into the grid is either not possible or not desirable under current conditions.

PV curtailment is typically triggered when the grid becomes constrained, demand is too low, or economic signals (like negative electricity prices) discourage further injection. In this way, curtailment acts as a control lever to protect grid stability and prevent overloading.

By implementing curtailment solutions we protect our customers during negative or low price periods from losses, allowing them to ‘pause’ generation when returning value would be negative.
