Summary
What solar panel owners need to know about Octopus Energy tariffs in 2026:
- Intelligent Octopus Flux delivers the strongest returns for solar + battery — automated peak-time export (~30p/kWh)
- Octopus Flux offers the same peak window with manual control + cheaper overnight import (~14.99p)
- Intelligent Octopus Go + Outgoing is best for EV owners — cheap overnight charging (~7-8p) + export earnings
- Outgoing Fixed (12p/kWh) is simplest for solar-only households with no battery
- Outgoing Agile offers variable rates that can spike higher — but only pays off with active management
- Solar4Good designs systems to be compatible with the best tariffs from day one
Why Your Tariff Matters More Than You Think
What your system actually saves or earns is shaped just as much by your electricity tariff as by the panels.
What actually affects your returns
- Export rate: what you’re paid for sending electricity back to the grid
- Import rate: what you pay when you need to buy electricity (~24–25p/kWh standard variable in 2026)
- Timing: when you generate, use, store or export that energy
2,000 kWh exported → ~£80/year
2,000 kWh exported → ~£240–£300/year
2,000 kWh exported → up to ~£400+/year
💡 Worth remembering
Every unit of solar you use yourself avoids buying electricity at ~25p/kWh — which is often where the biggest savings come from, before any export earnings are factored in.

“Solar4Good recommended Intelligent Octopus Flux when they installed our battery. The system charges and exports automatically — we haven’t had to touch anything and our bills have dropped dramatically.”

Tariff 1: Intelligent Octopus Flux — Best for Automated Solar and Battery Systems
The most advanced tariff for solar households with a compatible battery — including GivEnergy, Tesla Powerwall, FoxESS and Sigenergy. It automates when your battery charges, stores and exports energy.
During peak hours (typically 4pm–7pm), both import and export rates increase — often reaching close to 30p/kWh. Octopus manages your battery automatically.
⚠️ Important to understand
Intelligent Flux does not offer a cheap overnight import rate. The value comes from automated peak-time export — not from low-cost overnight charging. If cheap overnight charging is your priority (e.g. for an EV), Intelligent Octopus Go is a better fit.
Tariff 2: Octopus Flux — Best for Flexible Solar and Battery Setups
Same peak-window opportunity as Intelligent Flux — but without automation. Designed for homeowners who want manual control.
~14.99p import — useful for overnight battery charging
~24–25p import
~26.6p export
Tariff 3: Intelligent Octopus Go + Outgoing — Best for EV Owners with Solar
Provides a low overnight import rate — typically ~7–8p/kWh — for charging both your EV and your battery. When paired with Outgoing Octopus, you still earn from exported solar.
- Cheap overnight charging for both EV and battery
- Daytime usage from stored solar energy
- Export earnings from surplus generation

“We have solar, a Sigenergy battery and an EV charger — all installed by Solar4Good. They recommended Intelligent Octopus Go from the start. Our overnight charging costs almost nothing and the solar covers most of our daytime usage.”

Tariff 4: Outgoing Octopus Fixed — Best for Simple Solar-Only Setups
Pays a flat 12p/kWh for every unit exported — regardless of time of day. No battery or EV required. Can be paired with any import tariff.
💡 Outgoing Fixed vs basic SEG
At 12p versus a typical 4p SEG minimum, a home exporting 2,000 kWh annually earns around £240 rather than £80 — a difference of £160/year for zero additional effort.
Tariff 5: Outgoing Agile — Best for Advanced Users Chasing Maximum Returns
Rates change every 30 minutes based on wholesale prices — export values can vary significantly, with spikes much higher than standard tariffs during high demand.
⚠️ Honest note on Agile
For most households without a battery and active management, Outgoing Agile will on average earn less than the 12p fixed rate — not more. The higher returns are possible but only if you can consistently export during peak pricing periods.
Quick Comparison: Which Tariff Fits Your Setup
Best for: Solar + compatible battery | Export: Up to ~30p (peak) | Battery needed: Yes | Auto-managed: Yes
Best for: Solar + any battery | Export: Up to ~26.6p (peak) | Import overnight: ~14.99p | Auto-managed: No
Best for: Solar + EV | Export: 12p flat | Import overnight: ~7–8p | Battery: Optional
Best for: Solar only | Export: 12p flat | Battery: No | Simplest option
Best for: Advanced users | Export: Variable (can spike high) | Battery: Recommended | Active management needed
Which Octopus Tariff Should You Actually Choose?
If you have a battery and want it to run itself
Go with Intelligent Octopus Flux. Set-and-forget — Octopus handles battery scheduling automatically, targeting the 4–7pm peak window.
If you have a battery but want some control
Choose Octopus Flux. Same peak export window at slightly lower rate, but with a cheaper overnight import window. You schedule charging yourself.
If you have an EV (with or without a battery)
Go with Intelligent Octopus Go + Outgoing. Cheap overnight charging (~7–8p/kWh) for both EV and battery, plus export earnings from surplus solar.
If you have solar only and no battery
Stick with Outgoing Octopus Fixed. 12p/kWh for everything you export — simple, predictable, and a meaningful step up from basic SEG.
If you want to maximise returns and are comfortable with complexity
Consider Outgoing Agile. Only worth pursuing with a battery and active management or automation.

Why System Design and Tariff Choice Go Together
Knowing which tariff is best is only useful if your system is designed to take advantage of it.
- Battery compatibility: Intelligent Flux only works with GivEnergy, Tesla Powerwall, FoxESS, Sigenergy
- Smart meter requirement: all SEG and Octopus export tariffs require half-hourly export readings
- EV charger integration: Intelligent Go requires a smart-compatible charger configured alongside solar
- MCS certification: SEG registration requires MCS-certified installation (Solar4Good: NAP/72775/25/4)
📃 Solar4Good installation data

Conclusion
In 2026, Octopus Energy offers some of the most competitive and flexible export tariffs available for solar panel owners in the UK. The right choice depends on your setup, your usage patterns, and how actively you want to manage your energy.
Choosing the right tariff can change the financial performance of your solar system without changing the system itself. The difference between a basic export rate and a well-matched tariff can amount to hundreds of pounds per year.
If you’re installing solar or considering a battery upgrade, this is a decision worth making early. A well-matched system and tariff work together — and Solar4Good designs every installation with that compatibility in mind from the start.
