What is a home solar electricity sell-back scheme?
A home solar electricity sell-back scheme lets you export unused electricity from your solar panels to the grid. In the UK, this is usually done through a payment arrangement with your energy supplier. It means you can earn money or credit for the power you generate but do not use yourself.
This is sometimes called a “feed-in” style arrangement, although the old Feed-in Tariff scheme closed to new applicants in 2019. Most homeowners now use the Smart Export Guarantee, or SEG. This scheme was introduced to ensure homes with solar panels can still be paid for exported electricity.
How does it work?
During the day, your solar panels generate electricity for your home first. If you are producing more than you need, the extra electricity flows out to the national grid. A smart meter or export meter records how much you send back.
Your supplier then pays you for that exported electricity, usually as a rate per kilowatt hour. The rate varies by company, and some tariffs pay more than others. Payments may be made monthly, quarterly, or as bill credit, depending on the scheme.
Who can take part?
Most homes with solar PV panels can apply for a sell-back tariff if they meet the supplier’s rules. You usually need an export meter or a smart meter capable of measuring export. The system must also be installed safely and meet UK standards.
You do not have to export all your power. Many households use some solar electricity directly in the home and send only the surplus to the grid. This is often the best way to reduce bills, because you avoid buying that electricity from your supplier in the first place.
Why do people use these schemes?
The main benefit is that solar panels can lower both your electricity bills and your overall energy costs. Export payments help improve the return on your investment. They also make it easier to justify the upfront cost of installing panels.
These schemes can also support the wider energy system. By exporting clean electricity, households help reduce demand on fossil fuels. This makes home solar a useful part of the UK’s move toward greener energy.
What should you check before signing up?
It is worth comparing export rates, contract terms, and how often you will be paid. Some tariffs require you to also buy your electricity from the same supplier, while others do not. You should also check whether there are any exit fees or extra conditions.
It is a good idea to estimate how much electricity you are likely to export. Homes with daytime occupancy may use more of their solar power directly, while empty homes may export more. If you are considering battery storage, this can also affect how much you send back to the grid.
Frequently Asked Questions
Home solar electricity sell-back schemes are programs that let homeowners export unused electricity from their solar panels to the grid in exchange for bill credits or payments.
Home solar electricity sell-back schemes work by measuring the surplus electricity your solar system sends to the grid, then crediting or paying you based on the scheme rules and export rates.
Eligibility for home solar electricity sell-back schemes usually depends on having a grid-connected solar system, approved metering, and meeting the utility or program requirements in your area.
Homes with rooftop solar panels and a grid connection usually qualify for home solar electricity sell-back schemes, though apartment buildings and shared systems may face additional rules.
Many home solar electricity sell-back schemes require a smart meter or export meter so the utility can accurately measure electricity sent back to the grid.
Earnings from home solar electricity sell-back schemes depend on system size, sunlight, export rates, local tariffs, and how much electricity you export versus use yourself.
Home solar electricity sell-back schemes are related to net metering, but they are not always the same; some programs use full retail crediting while others pay lower export rates.
Home solar electricity sell-back schemes may use feed-in tariffs, but feed-in tariffs usually pay a fixed rate for exported power, while other sell-back schemes may credit exports differently.
Yes, home solar electricity sell-back schemes can reduce electricity bills by offsetting the cost of power you buy from the grid and by crediting the power you export.
Homeowners typically enroll in home solar electricity sell-back schemes by applying through their utility or program administrator, installing approved equipment, and completing meter setup.
Home solar electricity sell-back schemes usually require solar panels, an inverter, a grid connection, and metering equipment that can measure exported electricity.
Yes, battery storage can be used with home solar electricity sell-back schemes, and it may help you store solar power for later use instead of exporting it immediately.
Home solar electricity sell-back schemes may have tax implications depending on your location and how payments or credits are treated, so homeowners should check local tax rules.
Risks of home solar electricity sell-back schemes include changing tariffs, utility rule changes, lower-than-expected export value, equipment costs, and maintenance responsibilities.
Yes, home solar electricity sell-back schemes can change over time due to policy updates, utility program revisions, or new rate structures that affect export compensation.
Payments in home solar electricity sell-back schemes are usually calculated from measured exported kilowatt-hours multiplied by the scheme's credit rate, tariff, or payment formula.
Most home solar electricity sell-back schemes do not export power during outages because grid-tied solar systems shut down for safety unless they have special backup or islanding capability.
Renters usually cannot directly join home solar electricity sell-back schemes unless they have permission to install solar equipment or participate through a community solar arrangement.
Home solar electricity sell-back schemes may improve property value by making a solar-equipped home more attractive and by lowering ongoing electricity costs, though results vary by market.
Homeowners can compare home solar electricity sell-back schemes through local utilities, energy regulators, solar installers, and official government energy websites that publish program details.
