Selling Solar Electricity Back to The Grid: November 2024 Guide

Unsurprisingly, solar panels for homes are becoming increasingly popular to help protect the planet and secure future clean and renewable energy. However, a significant challenge remains: what happens to the excess electricity solar panels produce when it is not utilised? This extra energy is often wasted, resulting in missed opportunities and inefficiencies in using renewable energy. 

One solution which homeowners can benefit from is selling power back to the grid. With the aid of innovative solar technology and government payment schemes, solar panels are now more sustainable than ever, as no clean energy goes to waste. 

In this article, we will look at how to sell electricity from solar panels, how payments work and how much money you could make sending your excess solar energy back to the grid in the UK.

The reliance on non-renewable energy sources has become increasingly clear, and finding alternative solutions is key. Solar energy has emerged as a promising option, for renewable energy in the UK and most parts of the world. One of the biggest benefits of solar energy is the excess electricity it generates, which often goes unused. 

Photovoltaics have revolutionised the way we generate and consume electricity. Photovoltaic systems are a sustainable alternative to traditional fossil fuels since they use the sun's energy. In just one hour, the amount of sunlight the earth receives is enough to meet the electricity demands of every human being, for a year. However, not all this energy can be collected, and solar panels often generate unused electricity. 

One way to address this issue is to store excess electricity in solar batteries for later use. This can be particularly useful for off-grid applications or when there is little sunlight. Another option is to sell electricity back to the grid, which can earn homeowners money through schemes like the Smart Export Guarantee (SEG). This is one of the many advantages of solar energy.

In addition, advancements in technology have improved efficiency and lowered solar panel costs, making solar energy more accessible and cost-effective for consumers. The conversion efficiency of solar photovoltaic systems has enhanced by 0.5% each year for the last ten years, even as production costs have sharply declined. 

Governments and private organisations invest in solar farms and infrastructure to capture and distribute solar energy better. Incentives are also available for homeowners and businesses to install solar panels, which can help reduce energy bills and promote a cleaner environment. The potential for unused solar energy is enormous and can help reduce the reliance on non-renewable energy sources.

Solar panels can generate excess electricity during summer. The extra electricity is sent back to the grid, and the homeowner may receive credits from the utility company based on the net kilowatt-hours given to the grid. During winter, the homeowner can draw power from the credits accumulated throughout the summer. If the solar panels generate more electricity than is required, the homeowner can benefit, and sell solar energy to the grid.

Have you ever wondered what happens to the excess electricity solar panels generate? Well, the answer is quite simple. Any excess electricity from the solar panels can be sent back into the grid. This is known as net metering. 

There are several options for what to do with the excess energy:

The excess electricity generated by solar panels is not wasted potential. It can be used to power other homes and businesses, reducing the reliance on non-renewable energy sources. There are some challenges associated with solar panels. The required solar panel recycling capacity has to be built as part of a comprehensive end-of-life infrastructure also encompassing uninstallation, transportation, and storage facilities for solar waste. 

Additionally, there may be a hiatus when people are expected to give away unused energy for free while waiting to implement a new market. This makes energy firms compete to offer solar homes the best price for any unused energy they export. 

As a homeowner with solar panels, you may be able to receive payments for any excess solar energy you send back into the grid. Since 2019, the government have backed various schemes to help those who produce renewable energy, to benefit from sending their surplus into the national energy supply. 

The current scheme is the ‘Smart Export Guarantee’, which requires certain energy suppliers to pay a set rate per unit of electricity they receive. How it works is quite straightforward. As long as you are signed up for the scheme, and your solar panels are connected to the national supply, you can choose to either store or sell your excess solar energy. 

Once the energy is sent to the grid, the energy supplier will pay a set tariff rate per unit. We recommend you speak to your professional solar installer for any advice in setting this up for your system.

There is potential to earn between £80 - £170 yearly, if you choose to sell solar back to the grid. However, this amount can vary greatly depending on the size of your system and the tariffs offered by energy suppliers. 

This additional income can help reduce your other household bills, and increase the return on your initial solar panel investment, which should boost your yearly finances. 

The best way to earn through selling electricity back to the grid in the UK is by using the Smart Export Guarantee scheme.

Since January 2020, the Smart Export Guarantee scheme has offered small-scale low-carbon energy generates an opportunity to sell solar energy to the grid in the UK. Through this scheme energy suppliers can offer a tariff for the type of renewable energy you export. This can include solar, hydropower, wind power and others. 

There are some criteria you must meet to use the scheme, for example, your solar panels cannot exceed a capacity of 5MW (million watts) and must have an MCS certification to prove they were installed by a qualified engineer.

You must also have an export meter, or smart meter, to measure your energy production and send readings to your SEG supplier (known as an SEG licensee). We highly recommend having your circumstances properly assessed to choose the best solar export tariff in the UK.

Selling energy back to the grid can be a quick and easy way to make the most of your solar panels. As long as you understand what criteria and documentation you need, this will be a valuable resource for solar owners to access.

There are several benefits to storing or selling unused electricity generated by solar panels. These options allow homeowners to make the most of their solar energy systems and earn money through net metering or feed-in tariffs. With technological advancements and the potential for unused electricity, solar energy is becoming an increasingly attractive option for consumers and businesses. 

Here are some of the benefits of storing or selling unused electricity generated by solar panels:

In today's world, finding sustainable and renewable energy sources is crucial to meet the growing energy demand at homes and businesses. Solar power is a perfect solution; it is clean, affordable, and abundant. 

Here are some tips:

Utilising solar power is a practical and long-lasting solution for sustainable energy. Optimising solar panel installations and investing in energy storage is the key to maximising its potential. Additionally, adopting energy-efficient practices and exploring new applications can further maximise the use of solar power. Doing so can build a cleaner and more sustainable future for generations.
