If you’ve invested in solar panels, choosing the right electricity tariff is just as important as selecting the right equipment. While generating your own electricity can dramatically reduce your energy bills, the tariff you choose determines how much you pay for imported electricity and how much you could earn by selling electricity to the grid.
One tariff that often attract attention is Octopus Agile. Unlike traditional fixed tariffs, Agile changes its electricity prices every 30 minutes, allowing homeowners to buy electricity when wholesale prices are low.
But is it the best option for homes with solar panels?
At SolarTherm UK, we have helped thousands of homeowners across Essex, Kent, Suffolk, Hertfordshire and the wider South East and East Anglia understand how energy tariffs work alongside solar PV and battery storage, ensuring they maximise both savings and export income.
What Is Octopus Agile?
Octopus Agile is a time of use electricity tariff from Octopus Energy. Rather than charging one fixed price for electricity throughout the day, Agile follows wholesale electricity prices. Every day, customers receive 48 half hourly prices for the following day.
This means electricity prices can:
- Be significantly cheaper overnight
- Rise sharply during peak demand periods
- Occasionally even become negative, meaning customers are effectively paid to use electricity
For homeowners with flexible electricity usage, this creates opportunities to lower bills.
How Does Octopus Agile Work with Solar Panels?
Solar panels naturally generate the most electricity during daylight hours, often when household demand is relatively low. Instead of exporting all surplus electricity immediately, homeowners with battery storage can:
- Charge their battery using excess solar generation
- Use stored energy during expensive evening periods
- Purchase additional electricity overnight in Agile prices become very low
- Reduce reliance on expensive peak rate electricity
The combination of solar panels, battery storage and Agile pricing can significantly improve overall savings.
Is Octopus Agile an Export Tariff?
No, this is one area that often causes confusion. Octopus Agile is an import tariff, meaning it controls the price you pay when buying electricity. If you’re selling electricity to the grid, you’ll still need a separate Smart Export Guarantee (SEG) tariff. Many homeowners combine Agile with an SEG export tariff from either Octopus or another supplier.
What Is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) is a government backed scheme requiring licensed electricity suppliers to pay homeowners for surplus renewable electricity exported to the National Grid.
If your solar PV system produces more electricity than your home needs, your smart meter measures exported energy and your chosen supplier pays you for every kilowatt hour exported.
To qualify, you’ll typically need:
- MCS certified solar installation
- A compatible smart meter
- An approved export tariff
- Export metering
SolarTherm UK installs fully MCS certified systems, helping customers meet the requirements for SEG registration.
Octopus Agile vs Octopus Flux
One of the most common questions homeowners ask is whether they should choose Octopus Agile or Octopus Flux. Here’s a simple comparison.
| Feature | Octopus Agile | Octopus Flux |
| Import pricing | Changes every 30 minutes | Time-of-use pricing |
| Export payments | Separate SEG tariff required | Integrated higher export payments |
| Designed for batteries | Yes | Yes |
| Designed for solar | Yes | Specifically |
| Best for | Flexible electricity users | Solar and battery owners |
For households with solar panels and battery storage, Octopus Flux is often specifically designed around maximising both import savings and export income.
However, Agile may still suit homeowners who:
- Can shift electricity use overnight
- Own EV chargers
- Have home automation
- Want to optimise charging around wholesale prices
The right choice depends on your home’s electricity usage, battery capacity and export habits.
Can You Combine Agile with Battery Storage?
Absolutely, battery storage is where Agile becomes particularly attractive.
Your battery can:
- Charge when electricity prices are lowest
- Discharge when export prices are highest
- Store excess solar generation
- Reduce imported electricity during peak rate periods
Modern batteries with intelligent charging can even automate this process. At SolarTherm UK, we regularly design battery systems that work alongside flexible tariffs to maximise savings.
Is Agile Worth It Without Solar?
Yes, but the benefits are different. Without solar panels, Agile simply allows you to buy electricity more cheaply when wholesale prices fall. With solar panels, Agile becomes one part of a broader energy strategy that combines self-generation, battery storage, time of use electricity pricing and Smart Export Guarantee (SEG) payments, resulting in reduced reliance on the grid.
Should Solar Owners Export Electricity Immediately?
Not always. Many homeowners assume exporting every spare unit is the most profitable option. In reality, it often depends on:
- Current import price
- Current export rate
- Battery charge level
- Expected evening usage
- Tomorrow’s weather forecast
Sometimes it’s more valuable to store electricity and avoid buying expensive electricity later than it is to export immediately. Smart battery systems increasingly automate these decisions.
How Much Can Solar Homeowners Save?
Every property is different, but savings generally come from multiple sources:
- Lower electricity purchases
- Battery optimisation
- Reduced peak rate imports
- Smart Export Guarantee income
- Better self-consumption
Choosing the right tariff can increase the overall value of your solar investment without charging your solar panels themselves.
Is Octopus Agile Better Than a Fixed Tariff?
It depends on your lifestyle. Agile often suits homeowners who work from home, own battery storage, have an electric vehicle and can schedule appliances to work overnight. Being able to monitor electricity usage and optimise your usage around current rates can make Octopus Agile a lucrative tariff for solar PV and battery owners.
A fixed tariff however, may suit households wanting predictable bills without actively managing energy use. At SolarTherm UK, we always recommend comparing your household’s usage profile before switching tariffs.

Frequently Asked Questions
Yes. Agile can work well with solar panels, particularly when combined with battery storage that allows you to store cheap electricity and avoid expensive import periods.
No. Agile is an import tariff. You’ll still need a separate Smart Export Guarantee (SEG) tariff if you’re selling electricity to the grid.
For many solar and battery owners, Octopus Flux is specifically designed around solar generation and export. However, Agile may offer greater savings for households that can flexibly shift electricity use.
Yes, but not through Agile itself. You’ll need a compatible SEG export tariff to receive payments for exported electricity.
No, but battery storage usually delivers the greatest benefits because it allows you to buy electricity when prices are lowest and use it during expensive periods.
