SEG — earn from every surplus unit you export
Get paid for the energy your roof exports.
Smart Export Guarantee
Get Paid for the Power You Don't Use.
Every kilowatt hour of surplus solar you export earns money — a statutory obligation on licensed energy suppliers under the Smart Export Guarantee Order 2019.
How SEG works
From your roof to your supplier's payment.
Panels generate
Your roof produces power
Home uses what it needs
Self-consumption first
Surplus flows to grid
Excess is exported
Supplier pays you
Per kWh exported
The Smart Export Guarantee replaced the Feed-In Tariff (closed 2019). Unlike the FIT, SEG payments are market-rate export payments that licensed energy suppliers are legally required to offer all eligible solar owners under the Smart Export Guarantee Order 2019.
The SEG replaced the old Feed-In Tariff when it closed in 2019. Unlike the FIT, SEG payments are market-rate export payments that energy suppliers are legally required to offer to all eligible solar owners. There is no application deadline and no cap on earnings.
Every system we install is MCS-certified — your gateway to getting paid for surplus export.

MCS Certification Is Your Legal Gateway to SEG Payments.
SEG access legally requires an MCS-certified installation from a registered installer. Installers without MCS cannot offer their customers access to SEG — meaning those customers export surplus solar to the grid for nothing. Because every First Choice Solar system is MCS-certified, every First Choice Solar customer automatically qualifies for the highest available export rates from day one.
- Receive your MCS certificate from First Choice Solar (within 10 working days of commissioning)
- Apply to your chosen energy supplier's SEG tariff
- Confirm your smart meter is in place
- Export payments begin on your next bill — no further action required

A battery can significantly increase your SEG earnings. By storing surplus solar during the day and exporting during peak-rate evening windows — when time-of-use tariffs peak above 30p/kWh — your battery maximises the value of every kilowatt hour your roof produces. All figures illustrative; rates set by suppliers and change regularly.
