Selling Excess Electricity Generated From Your Home Wind Turbine
One of the most appealing aspects of owning a home wind turbine is the potential to not only generate your own electricity but to also be able to sell any excess electricity back to the grid. This concept, often referred to as 'net metering' or 'feed-in tariffs', allows homeowners to become part of the energy solution, contributing to the national grid's renewable energy sources. But how does this process work, and what do you need to know to get started?
Firstly, it's important to understand that the ability for you to sell electricity back to the grid depends on the regulations in your area and the policies of your energy provider. In the UK, the Smart Export Guarantee (SEG) scheme has replaced the previous Feed-in Tariff (FiT) scheme. Under SEG, licensed electricity suppliers with a certain number of customers are obligated to offer a tariff and pay small-scale low-carbon generators, like home wind turbine owners, for the electricity they export back to the grid. The rate paid varies between suppliers, so it is worth shopping around to find the best deal. To qualify for the scheme your installation must meet certain criteria and be carried out by a certified installer. This ensures that it is safe and that it is capable of efficiently generating electricity.
Before you start, you will need to have a smart meter installed that can accurately measure the electricity you're exporting. This allows your energy provider to monitor how much power you're sending back and ensure you're compensated correctly. It's also a good idea to consider the size of your wind turbine and your household's energy consumption. If your turbine generates more electricity than you use, selling the surplus can be financially rewarding. However, if your consumption is high, the amount available to sell might be less, though still beneficial. Engaging with your energy provider early on can provide clarity on the process and help you understand the potential financial returns.

How Are Roof Wind Turbines Installed on Residential Properties?
Installing a roof wind turbine on your home is an effective way to harness renewable energy. The process begins with a thorough assessment of your property to determine wind patterns and suitability. Our team will evaluate factors such as your roof orientation, wind speed, and potential obstacles. This step ensures that your turbine will operate efficiently, maximising energy output and ensuring a return on your investment.
Once your property is deemed suitable, the next step involves obtaining any necessary permits. In the UK, planning permission may be required, depending on local regulations and the turbine’s specifications. Our consultant will be able to guide you through this process, ensuring compliance with all legal requirements. Proper planning is essential to avoid future issues and ensure the installation meets safety standards.
With all of the necessary approvals in place, the installation process begins. The first step is securing the mounting system to your roof. This involves carefully anchoring brackets to support the turbine, ensuring it withstands various weather conditions. After the mounting system is in place, the turbine itself is installed, followed by the blades and rotor. Finally, the system is connected to your home’s electrical setup, and thorough testing is conducted to ensure optimal performance. With the installation complete, you can enjoy reduced energy bills and contribute to a more sustainable environment.

Understanding the Electricity Generation Capacity of Home Wind Turbines
The question of how much electricity does a home wind turbine generate is a common one among homeowners who are considering powering their home with renewable energy. The answer, however, is not as straightforward as you might hope. How much electricity that a home wind turbine can generate depends on a variety of factors including:
- The turbine's size
- The wind speed at your location
- how efficiently the turbine converts wind into electrical energy
Generally, residential wind turbines range in size from small 400-watt models, suitable for supplementing power usage, to larger 20-kilowatt systems capable of fully powering your home.
The Amount Of Energy A Wind Turbine Can Generate
The amount of power that your wind turbine can generate is directly related to the wind speed in your area. Wind turbines start generating electricity at wind speeds of approximately 3-4 metres per second. This is known as the 'cut-in speed'. Maximum output is achieved at a specific wind speed, beyond which the turbine will not increase its power output. This is known as the 'rated speed'. For example, a 5-kilowatt wind turbine, in an area with average wind speeds of about 6 metres per second, could generate approximately 8,000 to 9,000 kilowatt-hours per year. This is roughly enough to cover the electricity consumption of a typical UK household.
However, it is important for you to have realistic expectations and understand that the wind conditions can vary greatly, even within the same region. Before making a decision, it is advisable that you have a detailed assessment of your specific site's wind resource. After the assessment you will be provided with a comprehensive report that can help you to predict you wind turbine's performance more accurately. In addition if you integrate your wind turbine system with a battery storage solution, then that can maximise its efficiency even more by ensuring that any excess energy that is generated during windy periods does not go to waste.

Home Wind Turbine Installation Frequently Asked Questions
How big of a wind turbine do you need to power a house?
How big of a wind turbine do you need to power a house? A typical home uses approximately 10,649 kilowatt-hours (kWh), an average of 877 kWh per month. Depending on the average wind speed in the area, a wind turbine rated in the range of 5 to 15 kW would be required to make a significant contribution to this demand.
Are residential wind turbines worth it?
Are residential wind turbines worth it? A residential wind energy system can be a good long-term investment. However, because circumstances such as electricity rates and interest rates vary, you need to decide whether purchasing a wind system is a smart financial move for you.
Do you need planning permission for a wind turbine?
Only the first installation of any wind turbine would be permitted development, and only if there is no existing air source heat pump at the property. Additional wind turbines or air source heat pumps at the same property requires an application for planning permission.
How much does a home wind turbine cost UK?
Small roof-mounted wind turbines usually aren't more than 0.5-1.5 kW, and cost around £2,000 to 3,000, including installation. Standalone (or pole-mounted) turbines can vary a lot in size and, therefore, in price. They can cost anywhere from £7,000 for a 1.5 kW system, to £70,000 for a 15 kW system. 18 Jul 2023
Are mini wind turbines any good?
Harnessing the power of micro-wind or small-wind turbine systems to generate electricity, in an exposed position, can produce more than enough energy to power the lights and electrical appliances in a typical home.
