Small wind turbine generators are generally mounted on guyed poles, lattice towers or unguyed tubular towers. Depending on the proposed site and the size of wind turbine, concrete foundations may be required.
Installation of the wind turbine will involve the advanced laying of foundations, the assembly on site of the components and the erection of the wind turbine and tower using a winch.
Due to the skills involved, anything other than very small wind turbines should only be installed and serviced by qualified personnel. Find an installer. Wind Turbine Installation. Once the locations of the main items are fixed the on-site electrical distribution can be designed and the cable trenches and routes specified. We work with specialist structural engineers to get the groundworks designed and specified, and then manage a tender process for the works with several civil engineering contractors to ensure best value.
Similarly we specify the high and low-voltage works required and put the works out to tender with specialist subcontractors. Once the contractors are selected we project manage the process to ensure everything runs smoothly. In parallel we take care of the liaison between the client and the wind turbine supplier and heavy lifting contractor to ensure all of the access upgrades and crane pads are delivered on time and to the correct specification.
Once installed our wind consultants will arrange and oversee the G99 testing and turbine commissioning until the Final Acceptance Certificate is issued. Throughout the installation process the Renewables First Project Manager is the first point of contact for the client and will keep them up to date on progress. Renewables First are an experienced wind consultant and have a full project capability, from initial feasibility study through to wind consenting and installation.
A large crane vessel is likely to be required — either a shear-leg crane or other heavy lift unit. Alternatively, self-installing substation designs may find an increasing role in the future. Cable installation is a significant industry sector, with specialist design and planning, and installation vessels and equipment. The design and planning of the cable installation is an early activity, covering:.
First establish an energy budget. Because energy efficiency is usually less expensive than energy production, reducing your home's electricity use will probably be more cost effective and will reduce the size of the wind turbine you need.
The height of a wind turbine's tower also affects how much electricity the turbine will generate. A professional installer should help you determine the tower height you will need. An estimate of the annual energy output from a wind turbine in kilowatt-hours per year is the best way to determine whether it and the tower will produce enough electricity to meet your needs. A professional installer can help you estimate the energy production you can expect.
The manufacturer will use a calculation based on these factors:. Small wind energy systems can be connected to the electricity distribution system. These are called grid-connected systems. A grid-connected wind turbine can reduce your consumption of utility-supplied electricity for lighting, appliances, electric heating and cooling, and vehicle charging.
If the turbine cannot deliver the amount of energy you need, the utility makes up the difference. When the wind system produces more electricity than your household requires, the excess is credited and used to offset future use of utility-supplied power. Modern grid-connected wind turbines will operate only when the utility grid is available. They can also operate during power outages when configured to work in tandem with storage to form a home microgrid to provide back-up power.
Your utility can provide you with a list of requirements for connecting your system to the grid. For more information, see grid-connected home energy systems.
