How Jousto Automates Solar Curtailment for Maximum Efficiency
As more households and businesses adopt solar energy, electricity networks are imposing export limits to maintain grid stability. In some cases, excess solar energy that cannot be used or exported is simply wasted—a process known as solar curtailment.
However, with the right technology, solar curtailment can be managed intelligently to ensure that no energy is wasted. Jousto provides an automated solar curtailment solution that ensures your system remains compliant with grid regulations while maximising solar self-consumption and battery storage efficiency.
In this article, we’ll explore what solar curtailment is, why it happens, and how Jousto automates the process to ensure you get the most value from your solar power.
What Is Solar Curtailment and Why Does It Happen?
Understanding Solar Curtailment
Solar curtailment occurs when a solar energy system generates more electricity than can be used, stored, or exported to the grid. When this happens, the inverter reduces or shuts down solar generation to prevent exceeding grid limits.
Why Does Solar Curtailment Happen?
Grid Export Limits – Many electricity networks restrict how much power households can export to prevent grid instability. If your system exceeds the allowed export limit, the inverter automatically curtails production.
Low Household Energy Demand – On days when solar generation is high, but home energy consumption is low, excess energy has nowhere to go, leading to curtailment.
Full Battery Storage – If your home has a battery system and it is already fully charged, the system may have to curtail solar output to prevent overcharging.
Grid Congestion or Voltage Issues – Some networks impose dynamic export limits, reducing how much power can be sent to the grid at different times of the day, which can force your system to curtail solar generation unexpectedly.
While curtailment helps maintain grid stability, it results in wasted energy and reduces the financial benefits of your solar system. This is where Jousto’s automation technology makes a significant difference.
How Does Jousto Automate Solar Curtailment?
Jousto is an intelligent energy management system that ensures excess solar power is used efficiently within the home before any curtailment occurs. It does this through real-time monitoring, smart load management, battery optimisation, and grid export control.
1. Smart Load Management to Maximise Solar Self-Consumption
One of the most effective ways to prevent curtailment is to use more solar power within the home. Jousto does this by automatically directing excess energy to high-energy appliances instead of letting it go to waste.
If excess solar power is detected, Jousto turns on power-hungry appliances, such as:
Water heaters
Air conditioning systems
Pool pumps
Underfloor heating
Electric vehicle (EV) chargers
Jousto ensures that these appliances only use excess solar energy, so they do not increase grid electricity consumption.
By prioritising self-consumption, Jousto reduces the need for curtailment, ensuring that more of your solar power is put to good use.
2. Optimising Battery Charging and Discharging
If you have a home battery system, Jousto ensures that batteries are charged efficiently before any curtailment occurs.
During peak solar production, Jousto directs excess energy to charge the battery instead of curtailing generation.
If the battery is nearly full, Jousto slows down the charging rate to extend battery lifespan and prevent overcharging.
In the evening or during high electricity pricing periods, Jousto automatically discharges stored energy, reducing reliance on grid power.
This intelligent battery management allows homeowners to store and use more solar energy, minimising curtailment and maximising savings.
3. Managing Grid Exports to Stay Within Limits
For homes that must comply with export limits, Jousto ensures that your system never exceeds the allowed threshold.
Jousto monitors real-time grid export levels and dynamically adjusts solar output to avoid breaching the limit.
If an export limit is reached, Jousto automatically reduces grid exports by shifting power to appliances or battery storage.
If dynamic export limits are in place, Jousto adapts in real time, increasing or decreasing exports as allowed by the grid.
This means you can maximise your solar benefits while staying compliant with network regulations.
4. Predictive Energy Management
Jousto doesn’t just react to solar curtailment—it anticipates and prevents it.
Jousto uses historical energy data and real-time weather forecasts to predict high solar generation periods.
Before excess energy builds up, Jousto prepares appliances and battery storage to absorb more solar power.
If curtailment is unavoidable, Jousto gradually adjusts solar output rather than abruptly shutting it down, ensuring smoother energy management.
By taking a proactive approach, Jousto helps homeowners get the most value from their solar investment.
The Benefits of Jousto’s Automated Solar Curtailment
1. More Efficient Use of Solar Energy
Jousto ensures that every kilowatt of solar power is used effectively, whether through appliances, battery storage, or controlled grid exports.
2. Reduced Electricity Bills
By prioritising self-consumption, Jousto reduces reliance on expensive grid electricity, leading to lower power bills.
3. Extended Battery Lifespan
Jousto prevents unnecessary charging cycles and overcharging, helping extend the lifespan of home battery systems.
4. Compliance with Grid Export Limits
Jousto ensures that your system remains within allowable grid export limits, preventing penalties or restrictions from energy providers.
5. Greater Energy Independence
By minimising waste and maximising self-consumption, Jousto helps homeowners rely less on the grid, increasing energy independence.
6. Future-Proofing for Changing Grid Regulations
With more networks introducing dynamic export limits, Jousto ensures your system is ready to adapt to future changes.
