Wind Turbines

What it looks like

A wind turbine is made up of a number of key components. These are generally the same, whether for a small domestic turbine or a large commercial turbine.

Below gives an overview of the main components you are likely to see.

Wind Turbine

The wind turbine is mounted on top of a tower and contains all of the components needed to generate electricity. These include:

- Blades
- Gearbox
- Generator
- Measurement equipment


The wind turbine is installed on a tower.


The electricity produced by a wind turbine is direct current (DC). To use the energy on-site this needs to be converted into alternative current (AC). This is done by using an inverter.

The inverter is sized according to the peak output of the wind turbine e.g. a 1kWp turbine will have a different size inverter to a 10kWp turbine.

The inverter is installed as close to the PV modules as possible to reduce the loss of energy. For domestic systems, this is usually within the loft space.

AC/DC Isolators

The system may need to be isolated when maintenence work is required. This is achieved by the inclusion of isolators, normally 2 AC isolators and 1 DC isolator. These work on the same premise as a light switch and do not interfere with the overall running of the wind turbine system.

Generation Meter

A Generation Meter is installed to measure the amount of electricity produced by a photovoltaic system. This needs to be OFGEM approved. The Generation Meter enables you to understand how much energy you are saving locally and how much energy is being sent back to the National Grid. The meter normally located near the Consumer Board (Fuse box)

Visual Display

For larger commercial or community schemes, a visual display can be included. This graphically shows visitors the performance of the system and the amount of Carbon saved. This is a great way of promoting energy efficiency and to educate on sustainable matters
