If your solar panels are generating more electricity than your home uses, that surplus doesn’t have to go to waste. Across the UK and much of Europe, you can sell that excess power back to the grid and earn real money or bill credits for it. The process sounds straightforward, but the reality involves navigating export schemes, technical requirements, and country-specific regulations that can feel overwhelming. This guide cuts through the noise and gives you a clear, practical path from curious homeowner to active solar exporter.

Understanding your options for selling solar electricity
Before you can start earning from your surplus solar power, you need to know which export model applies to you. The framework varies significantly depending on whether you live in the UK or a specific EU country, and whether you own your home outright or live in a flat.
In the UK, the primary route is the Smart Export Guarantee (SEG). This government-backed scheme, introduced in 2020, requires licensed energy suppliers with more than 150,000 customers to offer export tariffs to eligible solar owners. You receive a payment per kilowatt-hour (kWh) exported, and rates vary between suppliers. Typical SEG rates in 2026 range from around 4p to 15p per kWh depending on which supplier and tariff you choose. The scheme is flexible, and you can switch providers to chase better rates, which gives you more control than older fixed feed-in tariff models.
In Europe, the picture is more varied. Many EU countries operate schemes broadly described as “self-consumption with sale of surplus,” where you primarily use your solar generation yourself and sell whatever remains. As one clear example, France’s framework allows households to sell surplus PV electricity to EDF under specified conditions, with the purchase price fixed by government decree. Germany operates a feed-in tariff model for smaller systems, while countries like Spain and the Netherlands have their own distinct rules around net metering and export compensation.
Here is a quick comparison of the main export models available across the UK and key EU markets:
| Country | Export model | Who manages it | Typical rate (2026) |
|---|---|---|---|
| United Kingdom | Smart Export Guarantee (SEG) | Licensed energy suppliers | 4p to 15p per kWh |
| France | Sale of surplus to EDF | Government-set via decree | ~4 euro cents per kWh |
| Germany | Feed-in tariff for small systems | Grid operators | ~8 euro cents per kWh |
| Spain | Net metering / surplus credit | Network operators | Variable by region |
| Netherlands | Net metering (phasing out) | Grid operators | Transitioning in 2026 |
Key things to understand across all these models:
- Feed-in tariffs pay you for every unit generated, whether you use it or not.
- Export tariffs (SEG) pay only for what you actually send to the grid.
- Net metering offsets what you owe by crediting your bill for exports.
- Sale of surplus schemes pay you for generation left over after self-consumption.
If you want to understand how self-consumption tips can reduce how much surplus you export in the first place, that knowledge feeds directly into calculating whether exporting makes financial sense for your situation.
Pro Tip: Always check whether your country’s export scheme has a capacity cap. In France, for example, the sale of surplus option is available for systems below certain thresholds, so larger installations may face different rules. Similarly, understanding 800W balcony rules is essential for apartment dwellers looking at plug-in solar exports in EU countries.
What you need before you can sell solar electricity
Once you understand your export options, it is time to check whether your setup actually qualifies. Eligibility is not automatic. There are technical, administrative, and regulatory boxes to tick before your first export payment arrives.
The French government’s guidance illustrates this well: households can choose to sell surplus PV instead of only self-consuming, but this choice comes with specific contract conditions, grid registration requirements, and metering obligations. The same principle applies across all markets.
Here is what you will typically need in place:
- A grid-connected solar system: Off-grid setups cannot export to the grid. Your system must be physically connected through your property’s main supply.
- An MCS-certified installation (UK): In the UK, your installer and system must be certified under the Microgeneration Certification Scheme (MCS) to qualify for the SEG. No MCS certification means no export payments.
- A smart meter or export-capable meter: Standard meters cannot measure export flow. Most suppliers will install a smart meter as part of your SEG application at no extra charge.
- An export contract or registration: In France and other EU countries, you must sign a specific purchase contract with your designated grid buyer. In the UK, you apply directly to an SEG-licensed supplier.
- An appropriate inverter: Your inverter must be grid-tied and compliant with local grid standards, such as G98 or G99 in the UK. Learn more about inverter requirements before selecting your system.
| Requirement | UK (SEG) | France (surplus sale) | Germany (feed-in) |
|---|---|---|---|
| Grid connection | Required | Required | Required |
| MCS or equivalent | MCS required | Certified installer | Certified installer |
| Smart meter | Required | Required | Required |
| Export contract | Applied via supplier | EDF contract | Grid operator |
| System size cap | No upper cap for SEG | Below specified threshold | Up to 100 kWp for small tariff |

Important: Always check for the latest contract requirements and grid integration rules before installing or applying to export. Export schemes can change with little notice, and signing up under outdated terms could mean missing out on payments or facing compliance issues.
Step-by-step: How to sell solar electricity back to the grid
With the right system in place and eligibility confirmed, the actual process of getting set up to export is more manageable than most people expect. Here is how it typically unfolds.
-
Choose your national or local export scheme. In the UK, compare SEG tariffs from multiple licensed suppliers. Rates, contract lengths, and payment terms differ. In France, contact EDF OA (the designated buyer for small producers) to start a surplus sale application. In Germany, contact your local grid operator (Netzbetreiber) to register under the feed-in tariff.
-
Submit your application with system documentation. You will need your MCS certificate (UK), inverter compliance data, system size details, and installation date. In France, this is submitted as part of the formal sale of surplus contract process.
-
Arrange grid connection inspection if required. For larger systems (above 3.68 kW in the UK), your Distribution Network Operator (DNO) may require a G99 application and inspection. Smaller systems typically self-certify under G98. This step is about safety and grid stability, not bureaucracy for its own sake.
-
Get your export meter or smart meter installed. Your supplier or grid operator will usually handle this. Once installed, your export readings are recorded separately from your import usage.
-
Set up monitoring. Most modern inverters come with monitoring apps that show real-time generation, self-consumption, and export data. Use this to track what you are actually sending to the grid.
-
Receive payments or credits. In the UK, SEG payments are typically made monthly or quarterly depending on your supplier. In France, EDF pays for surplus at the government-set rate, currently around 4 euro cents per kWh under the national framework. In Germany, feed-in payments are typically made monthly by your grid operator.
Pro Tip: Apply for your export contract or SEG tariff before or immediately after installation, not months later. Processing times vary, and in some countries export payments are not backdated to your installation date. Early application means earlier income.
Export rates and policy designs can shift with regulatory updates, so it is worth building the habit of reviewing your contract terms annually. As noted in the French national policy framework, rates, eligibility thresholds, and contract conditions can change via decrees, so confirming current terms for your country and installation size is not optional, it is essential.
Looking at the financial side, our solar energy cost basics guide helps you model whether export income meaningfully improves your payback period compared to focusing on self-consumption alone.
Common pitfalls and how to maximise your surplus income
Starting to export is one thing. Consistently earning well from it is another. Many solar owners leave money on the table simply because of avoidable mistakes.
Here are the most common pitfalls and how to sidestep them:
- Not updating contracts after regulatory changes. Export rates and scheme conditions are not permanent. Countries regularly revise purchase prices by government decree. If you signed up years ago and never reviewed your contract, you may be on outdated terms.
- Inverter settings misconfigured after installation. Some installers set inverters to export-limit mode by default, capping what you send to the grid even when your battery is full. Check your inverter settings with your installer after commissioning.
- Generating at peak times but exporting at low-value periods. In markets with time-of-use export tariffs, the timing of your exports matters. Exporting at off-peak times earns less. A home battery can shift surplus generation to export during higher-rate windows.
- Missing metering data deadlines. Some contracts require you to submit meter readings by a specific date each quarter. Missed readings can result in estimated payments that undercount your actual exports.
- Not taking advantage of self-consumption first. Exporting at 4 to 8 euro cents per kWh while importing electricity at 25 to 35 cents per kWh is a poor trade. Maximising what you consume directly always gives better financial returns than exporting the same units.
Warning: Failing to document your exports accurately can result in missed payouts or disputes with your supplier. Keep records of your inverter monitoring data, meter readings, and all correspondence with your export buyer or supplier. A simple monthly log takes minutes and could save you significant hassle if a query arises.
Battery storage plays a bigger role here than many people realise. A well-configured battery lets you store midday generation and either use it during the evening peak or export it during a higher-rate window. Staying informed about latest solar technology also helps you spot when system upgrades could meaningfully improve your export yield.
Pro Tip: Set a calendar reminder every six months to check your country’s current export rate and compare it with the terms on your contract. Rate changes that are not automatically applied to existing contracts represent real lost income over time.
A smarter approach to selling your solar electricity
Here is an honest take that most export guides skip over: chasing export income is not always the best financial strategy, and in some cases it actively works against you.
The gap between what you pay to import electricity and what you receive to export it is significant in almost every European market. In France, you might sell surplus at 4 euro cents per kWh while paying 25 euro cents or more to buy it back in the evening. That 6:1 ratio means that every unit you self-consume is worth roughly six times more than the same unit exported. The maths is not subtle.
This does not mean exporting is worthless. On the contrary, if your system genuinely produces more than you can use, exporting that surplus is far better than curtailing it. But the real opportunity is in designing your energy use around maximising self-consumption first, and treating export income as a bonus rather than the primary goal.
Regulatory risk is the other piece that rarely gets discussed openly. Export rates are set by governments and grid operators, not locked in perpetually. If you build a financial model around a specific export rate and that rate changes in two years, your assumptions fall apart. The French surplus purchase price, the German feed-in tariff for small systems, and the UK SEG rates have all changed over time. Building flexibility into your home energy system, whether through battery storage, smart appliance timing, or EV charging, gives you options regardless of what policy does next.
There is also the question of solar panels and home value. A well-designed solar and storage setup that genuinely reduces your bills adds measurable value to your property. That long-term asset value often outweighs marginal improvements in export income. Think holistically: self-consume first, sell surplus second, and design your system for adaptability.

Frequently asked questions
Can I sell solar electricity if I live in an apartment?
Yes, you can sell surplus if your system is grid-connected and local rules allow. In countries like France and Germany, flat-friendly schemes exist for small solar setups, including balcony systems in some cases.
How much can I earn from selling surplus solar electricity?
Earnings vary by country, contract type, and current export rates. In France, the government-set rate is approximately 4 euro cents per kWh, while UK SEG rates can reach 15p per kWh depending on supplier.
Do I need a special meter to export electricity to the grid?
Yes, almost universally. A smart meter or an export-capable meter is required so your supplier or grid operator can accurately record how many units you send to the grid and pay you accordingly.
Can export rates for solar electricity change after I sign up?
Absolutely. As confirmed in the French regulatory framework, rates, eligibility thresholds, and contract conditions can change via government decrees, so reviewing your terms annually is essential.
Is selling solar electricity worth it in countries without feed-in tariffs?
Exporting surplus can still add value, but self-consumption usually delivers far better financial returns where export rates are low. Treat export income as a useful supplement, not the foundation of your solar investment case.
