Optimising your home solar system with a solar battery storage setup doesn’t just make your energy usage greener, it can save you a significant amount of money on your electricity bills. Choosing the right Octopus Energy tariff is key to the savings you can make. Time-of-use tariffs let you pay less for imported electricity and earn more for exported electricity, maximising the value of every kilowatt hour your solar panels generate.
Why Tariff Choice Matters for Solar and Battery Owners
Most standard energy plans charge a flat rate for electricity, ignoring when you actually use or export power. Octopus Energy’s smart tariffs take a different approach, rewarding households that switch to renewable energy and shift consumption to off-peak periods or export solar at peak times. If you have solar panels, home battery storage, an EV or a heat pump, selecting a time of use tariff could transform your setup and save you even more on your electricity bills.
Intelligent Octopus Go
Intelligent Octopus Go is designed for homeowners who want hands-free savings. It offers six hours of overnight cheap electricity, at just 7p per kWh, perfect for charging your solar battery or EV. Surplus energy can be exported at 15p per kWh through the Fixed Outgoing tariff. With the Smart Charging API, compatible systems like GivEnergy, Enphase and Tesla Powerwall can optimise charge and discharge cycles automatically.
Octopus Go
Octopus Go is ideal for those who don’t have a battery suitable for smart integration or want to control when their solar battery charges and discharges. Its five hour cheap overnight rate is perfect for charging your solar battery and EV at only 8.5p per kWh. You can pair this with an fixed outgoing rate of 15p per kWh for your exported electricity. Even without API integration, this tariff offers excellent overnight battery charging and all day home power.
Octopus Flux
If you are interested in a tariff that is designed to maximise savings on importing and exporting, Octopus Flux is the tariff for you. With three unit rates for imported and exported electricity based on demand on the grid. Off-peak rates run from 2am until 5am and charge 14.99p per kWh for imported electricity and pay 4.74p per kWh for exported electricity. The Standard day time rate is 24.98p per kWh imported and 13.32p per kWh exported. This is paired with a peak export period of 4pm until 7pm where exported electricity is paid at 34.97p per kWh and imported is charged at 26.6p per kWh. By optimising charging and discharging of your battery manually, you can maximise savings, Flux can outperform many fixed-rate plans.
Intelligent Octopus Flux
Intelligent Octopus Flux automates Flux, providing hands-free optimisation. Import and Export rates are balanced throughout the day. Octopus Energy uses a virtual power plant model to manage multiple home batteries to charge during low-cost, low-carbon periods and discharge at peak times. Intelligent Octopus Flux is compatible with GivEnergy and Enphase solar batteries.
Octopus Agile
For those who want a more hands-on approach to their electricity tariff and to control the price they buy and sell at, Octopus Agile tracks wholesale energy prices every 30 minutes. Prices can go below zero, giving solar and battery owners the chance to buy cheap and sell high. Export options include fixed outgoing at 15p per kWh or Agile Outgoing which matches half-hourly Agile import prices. Agile is ideal for those who want to be proactive with their energy usage and are tech savvy, able to monitor price swings with smart apps and automation.
Cosy Octopus

This tariff is perfect for households who have high heating bills and need the predictability of charging windows to support their heat pump usage.
