Household Usage First
Electricity generated by solar panels is normally used within the property before anything else.

Smart Export Guarantee Explained
The Smart Export Guarantee (SEG) allows eligible households to receive payments for surplus electricity exported back to the grid from solar PV systems.
What Is the Smart Export Guarantee?
The Smart Export Guarantee, commonly known as SEG, is a government-backed framework requiring certain electricity suppliers to offer export tariffs for renewable electricity exported to the grid.
It replaced the older Feed-in Tariff scheme for new applicants.
Under SEG, homeowners with eligible solar PV systems may receive payments for exported electricity.
How SEG Works
Solar electricity is generally prioritised in a specific order.
Battery Charging Second
If battery storage is installed, surplus electricity may charge the battery before export occurs.
Grid Export Last
Remaining surplus electricity may then be exported to the grid under an SEG tariff.
How Are Export Payments Calculated?
SEG payments are usually based on the amount of electricity exported to the grid.
Export measurement typically relies on smart meter data.
Tariff structures vary between electricity suppliers and may include:
Export tariffs can change over time, so homeowners should review available options carefully.
- Fixed export rates
- Variable export rates
- Time-based tariffs
- Smart tariff integration
Bespoke PV Insight
Increasingly, the real value of solar PV comes from self-consumption rather than export payments alone.
Battery storage, EV charging and wider electrification are changing how households use solar electricity.
Why Self-Consumption Matters More Than Ever
Self-consumption is becoming increasingly important.
Electricity used directly within the property is often more valuable than exported electricity.
This is because imported electricity prices are often significantly higher than export tariff rates.
Many households are therefore increasingly focused on:
- Using more solar electricity directly
- Battery storage integration
- EV charging from solar
- Reducing imported electricity
- Long-term energy resilience
How Battery Storage Changes Export Behaviour
Battery storage changes how solar generation is used.
Battery storage can significantly reduce exported electricity.
Instead of exporting surplus solar generation immediately, battery systems can store electricity for later household use.
This may help:
- Increase self-consumption
- Reduce imported electricity
- Improve evening energy usage
- Support EV charging
- Improve resilience
Can EV Charging Reduce Exported Electricity?
Yes. Electric vehicles can absorb surplus solar generation directly.
Smart EV chargers may prioritise surplus solar electricity, reducing exported electricity while improving household self-consumption.
As EV adoption increases, many households are increasingly viewing solar PV, battery storage and EV charging as one integrated energy system.

SEG Is Only One Part of Solar Value
Export income is only one part of long-term solar value.
Solar PV is increasingly about long-term energy flexibility and resilience.
Many homeowners are now thinking beyond simple export income.
Key priorities increasingly include:
- Reduced grid reliance
- Protection from future electricity price rises
- Future EV charging
- Heat pump integration
- Battery storage flexibility
- Long-term energy resilience
Exporting Electricity vs Using It Yourself
Many homeowners initially focus heavily on export payments, but self-consumption is often more financially valuable.
Exporting Electricity
- Surplus electricity is sent to the grid.
- Export rates may be lower than import prices.
- Income depends on tariff structure.
Self-Consumption
- Electricity is used directly within the property.
- Reduces imported electricity purchases.
- Often improves overall long-term system value.
Why Solar Economics Are Changing
Historically, some homeowners viewed solar primarily as a way to generate export income.
Today, rising electricity prices, EV charging, battery storage and heat pump adoption are changing how solar PV systems are valued.
Increasingly, homeowners are focusing on reducing imported electricity and improving long-term energy flexibility rather than relying purely on export payments.
This shift is one reason battery storage and smart energy management systems are becoming increasingly important.
How Smart Energy Systems Improve Self-Consumption
Smart energy management can improve how solar generation is used.
Modern solar PV systems are increasingly integrated with wider household energy technologies.
- Battery storage
- Smart EV charging
- Time-of-use tariffs
- Heat pump integration
- Load shifting
- Smart home automation
Why Smart Tariffs Are Becoming More Important
Some electricity suppliers now offer smart export tariffs linked to time-of-export pricing.
This means exported electricity may be worth more at certain times of day depending on electricity demand and wider grid conditions.
As battery storage and EV charging become more common, tariff optimisation is becoming increasingly important within wider household energy planning.
How Future Electrification Changes Solar Value
Solar PV is increasingly part of a wider home energy ecosystem.
Household electricity demand is changing rapidly.
Electric vehicles, heat pumps and wider electrification are increasing the importance of solar generation, self-consumption and battery storage integration.
- EV charging
- Heat pumps
- Home batteries
- Smart tariffs
- Flexible energy usage
- Long-term resilience
Why Professional System Design Matters
Good design improves long-term performance and flexibility.
Export performance depends heavily on system design and household usage patterns.
A professionally designed solar PV system should consider:
- Roof orientation
- Battery storage integration
- EV charging plans
- Household usage patterns
- Future heat pump demand
- Export limitations
