You’re offering or want to offer aFRR services? Let us introduce the Teleport’s new feature: solar irradiance power limiter.

If you operate solar PV installations, this feature gives you precise control over your power output, helping you meet grid requirements and participate in balancing services like automatic Frequency Restoration Reserve (aFRR).

Here’s how it works, why it matters, and how you can start using it today.

What is the solar irradiance power limiter?

Simply put, the solar irradiance power limiter helps manage how much electricity your solar panels feed-back to the grid based on aFRR requirements.

This feature works by using weather data – specifically sunlight measurements (called irradiance levels) – to determine how much electricity your solar panels could produce at full power. Then, it calculates how much you’re allowed to send to the grid, and automatically reduces the output if needed (or in some cases, increases it!).

For example:

• Step 1: A sensor measures the solar irradiance (how strong the sunlight is on a specific area).

• Step 2: The Teleport estimates what’s the maximum power your system could produce with no limits under the current conditions (this is called “uncurtailed power”, or “available power” in the Teleport data model). 

• Step 3: A calculation is done using the delta setpoint communicated through the API. The delta can be positive (for upward regulation) or negative (for downward regulation).

• Step 4: The Teleport sets the setpoint to min(available power, non-aFRR curtailment setpoint *) + delta. In other words, it limits the actual power production to match grid demands or specific service requirements like aFRR.

*It’s possible to also have curtailment setpoint coming from regular energy trading, or from the DSO. Learn more about how the Teleport combines all those signals.

This feature is particularly useful when providing aFRR services, which require quick, automatic adjustments to power output to balance supply and demand on the grid.

When is this feature a good fit for you?

The solar irradiance power limiter is ideal if:

• Your solar PV system is equipped with an irradiance sensor or pyranometer.

• You’re participating in aFRR services or need to limit power output relative to uncurtailed potential.

If you don’t have these sensors, no worries – there are other ways the Teleport can help you manage your energy output. Check the Teleport’s use cases.
