Powering Your ROI: How Ofgem’s Latest SEG Report Makes Solar Smarter Than Ever


Solar installation on a pitched roof

The energy landscape in the UK just got even more exciting for homeowners and businesses generating their own renewable electricity. The newly published Smart Export Guarantee (SEG) Annual Report from Ofgem – covering the period from April 2024 to March 2025 – reveals stunning growth in renewable exports, stronger payouts and a market that’s innovating to reward people who choose solar.

Here’s what it means – and why SolarTherm UK is uniquely positioned to help you benefit.

SEG Year 5 by Numbers: Growth You Can Feel

According to Ofgem’s Year 5 SEG Annual Report:

  • Exports soared to 443 GWh of low carbon electricity – enough to power over 160,000 typical UK homes for a year.
  • Payments to generators climed to £56.97 million – an 86% jump year on year.
  • 270,395 installations were registered on SEG tariffs by March 2025, representing a 63% increase over the previous year.
  • The total installed export capacity hit 1,585 MW, another strong indicator of growing solar adoption.

What does this all mean? It’s clear: solar power isn’t just cleaner – it’s paying off and the rewards are escalating as more people export surplus energy to the grid.

A Market Evolving for You

One of the most striking trends in this year’s SEG report is the expanding range of tariffs and supplier innovation. There were 50 SEG tariffs active in the market, up from 37 the year before, with many suppliers now offering tariffs tied to additional services or products with much higher export rates.

In some cases, tied tariffs significantly outperform basic options, creating more choice and income potential for generators. This competitive diversity shows suppliers are actively innovating – and that means better value for solar owners.

Why This Is Good New for Solar Customers

Here’s why SEG Year 5 matters for anyone thinking about solar – or already generating clean power:

More Ways to Earn

Every kilowatt hour (kWh) of exported renewable energy now earns a fair payment from suppliers. That turns your excess solar power – previously unused or wasted – into ongoing revenue.

Bigger Market = Better Tarriffs

As the market matures, suppliers are competing for customers. That means more tariff choices and more chances to earn more.

Solar + Storage = Maximum Return

SEG’s innovation trend includes battery linked tariffs that reward homeowners and businesses who pair solar with battery storage – increasing overall export opportunities.
