As more homes in the UK are going solar, homeowners are seeking ways to get the most value from their solar panels. The most obvious advantage of solar panels is that they help to lower electricity bills, but many people don’t know that they can also make money by sending excess electricity back to the grid. This is where the Smart Export Guarantee (SEG) comes in.
The Smart Export Guarantee (SEG) UK scheme pays eligible householders for the excess renewable energy their solar panels produce. In 2026, SEG is still one of the best incentives for solar owners, as energy costs are still a worry.
Solar Dream breaks down the science behind SEG in this guide, the eligibility criteria, the amount you may be able to make and how a professionally installed solar system can help you maximize your savings and export income.
What is the Smart Export Guarantee?
The SEG was a government initiative launched in 2020 after the end of the Feed-in Tariff scheme. It mandates that big electricity companies pay renewable energy producers for electricity they sell to the National Grid to homes and businesses.
If the solar panels are producing more electricity than the property consumes, the excess electricity is automatically exported. With SEG, your supplier will pay you for each unit of electricity returned to the grid.
The SEG payments are not based on total electricity generation but only on exported electricity as opposed to the previous Feed-in Tariff.
What is the SEG Scheme?
It is simple to do:
- Your solar panels generate electricity, which powers your home during the day.
- Your home uses the electricity it needs.
- Your system exports surplus electricity to the grid.
- A smart meter records the amount of electricity you export.
- Your chosen supplier pays you according to its SEG tariff.
Your earnings will vary according to solar system size, energy consumption habits, export levels and the tariff that your supplier is providing.
Households that consume more electricity during the day will export less, and households that are not at home during working hours will export more, and receive more SEG payments.
Who can be a member of SEG?
In general, the following criteria must be fulfilled in order to benefit from the Smart Export Guarantee in 2026:
MCS-Certified Installation
Your solar panel system has to be installed by a Microgeneration Certification Scheme (MCS) accredited installer. This certificate verifies the installation is in accordance with the recognised industry standards.
Smart Meter
An appropriate smart meter must be used to measure exported electricity accurately. If there are no export readings, suppliers are unable to work out SEG payments.
Eligible Renewable Technology
SEG invests in a number of renewable technologies, such as solar photovoltaic (PV) systems, wind turbines and hydro generation systems. Solar panels are the most convenient choice for most homeowners.
System Capacity Requirements
The majority of domestic installations are well within the capacity limits of eligibility for SEG.
All installations at Solar Dream are built to industry standards and to ensure homeowners are eligible for export tariff.
What will be the earnings from SEG in 2026?
The most frequently asked question by homeowners is: “How much will I be paid for solar energy in the UK?”
The answer varies depending on a number of factors such as the size of your solar system, how much electricity you generate in a year, how much you export and the tariff you select.
The average 4kW solar system can produce 3,500 to 4,200kWh of electricity per year. Some of that energy can be sold back to the grid based on the household’s energy consumption.
For example:
- 1,500 kWh exported at 10p per kWh = £150 per year
- 2,000 kWh exported at 15p per kWh = £300 per year
- 2,500 kWh exported at 20p per kWh = £500 per year
Although earnings differ, SEG payments can enhance the overall ROI, especially with the savings on electricity bills.
Selecting an appropriate SEG Tariff
SEG tariffs are not equal. Payment levels will vary depending on the supplier’s rates.
When looking at tariffs, homeowners should take into account:
- The amount of money that is paid for each kWh exported.
- Both fixed and variable tariff structure
- The conditions and terms of the contract.
- Supplier requirements
The following are potential time-of-use export options:
Some suppliers will provide a better rate, but will also make it compulsory for the homeowner to buy electricity from them. A thorough consideration of the options available can help to maximise export income.
Will Battery Storage Boost Your Savings?
As solar power has become more common in homes, battery storage has become more popular.
A battery stores the excess electricity for later use, as opposed to exporting it right away. This enables homeowners to consume more of their own solar electricity in the evening when demand is greater.
The advantages of battery storage are:
- Lower electricity bills
- Lower reliance on the power grid.Less reliance on the electrical grid.
- Greater energy independence
- Better utilization of solar power generation
Solar Dream battery storage solutions can also complement a homeowner’s SEG-ready system, and are a good option to consider if they want to maximise the use of their solar system.
The importance of inverter quality.
One of the most crucial parts of any solar energy system is the inverter. It takes the direct current (DC) generated by the solar panels and transforms it into alternating current (AC) that is required by household appliances.
A good quality inverter helps:
- Improve system efficiency
- Maximise electricity generation
- Enhance export monitoring
- Increase long-term reliability
The selection of the appropriate inverter can directly affect solar savings and SEG income. Solar Dream installs top quality equipment that will provide long lasting service.

FAQs
The SEG is a Government-backed scheme that incentivizes people with renewable energy generation at their property to sell electricity back to the National Grid.
Yes. Typically, a smart meter that measures exported electricity is needed to receive SEG payments.
The amount is dependent on system size, export levels and tariff rates, but most homeowners are able to make between £100 and £500 year.
Yes. If there is a better export tariff available the homeowner can switch supplier, subject to supplier terms.
