First, the energy in the wind turns the blades around the rotor. Second, the rotor is connected to the main shaft, which consequently spins a generator to create electricity.

Chiefly to reduce turbulence, it is better to site the turbine away from buildings and trees. It must be remembered that when installing and maintaining the turbine, the tower itself will need to be laid flat on the ground. For this reason a clear space equal to the height of the tower is adequate.

A turbine should last for 20 years or comparatively more if regularly serviced.

Notably our most popular turbines have been designed to be very quiet. Therefore a suitably sited wind turbine can operate without any noise nuisance to nearby residents. However, the nearest residents to the wind turbine should be more than 135m away from the wind turbine base in order to eliminate noise issues.

By all means livestock are able to graze in the same field as a turbine undisturbed by its presence. Equally important, any potential impact to bats and birds can be mitigated by suitable siting. Current Natural England guidance suggests a setback distance of 50m from any trees, hedgerows, buildings or water bodies.

It is important to realise that we won’t sell you a wind turbine unless we know it’s going to work for you.

By installing a PV system, occupiers can generate their own ‘green’ electricity, not only reducing electricity bills but helping to offset carbon emissions. PV will play an increasingly important role in contributing towards ‘sustainable development’.

Key advantages of this type of electricity generation include:

  • Emission free
  • Noise free
  • Requires minimal maintenance (no moving parts)
  • Can be integrated in, or mounted onto an existing building structure
  • Causes minimal visual intrusion

Recent changes to planning guidance mean that you do not have to seek planning permission for roof mounted solar systems less than 200mm above your roof or for ground-mounted systems under 9m₂ unless your array is intended for a listed building. In the case of a listed building, you will need to apply for consent from your local planning authority.

However, some local authorities will insist that you acquire planning consent regardless, particularly if your potential site is in a protected area.

Therefore, always check before going ahead as retrospective permissions can be difficult to obtain.

A solar electric system is commonly referred to as a photovoltaic, a PV generator or Solar PV. It converts sunlight into electricity by a solid-state process involving no moving parts and producing no noise or emissions.

There are two types of solar PV. The most robust and efficient solar PV cells at present are made from silicon crystal and are either mono-crystalline (extracted from a single crystal) or poly-crystalline (made up of many crystals). The alternative option is a thin-film solution, which is more flexible but less efficient.

These two types of solar technologies are then incorporated into the following:

PV Panels/ Modules

Most PV systems are formed of an array of PV modules. These modules comprise a series of interconnected PV cells, laminated between glass and a back-sheet and held within a rigid aluminum frame. PV modules are usually the most cost effective solution and can be combined to form an array of the correct size for your building and electricity demand.

PV Tiles

PV tiles are a type of Building Integrated PV (BIPV). They can be used to directly replace standard roof tiles. They are usually more expensive than modules, but can be very cost effective where they are used to replace other building materials.

PV Glazing/Cladding

PV glazing can also be used to replace conventional building materials such as the glass roof of a conservatory. PV glazing functions to provide shelter, shading and electricity in one material. Like glazing, solar cladding can also be used in the place of other materials and can be made bespoke in order to fit the solar features of your site and electricity demand.

Solar PV could be a good option if you are considering replacing part of a roof or building façade. In some cases, solar materials may work out cheaper than conventional building materials or even offset their cost. If your potential site is a new build, it is worth considering whether you could build electricity generation into the actual fabric of the building.

The more south-facing a PV system can be, the better, as this means more sunlight will reach the PV cells. However, PV arrays will continue to work effectively at other orientations – from east through to west.

That said, annual output can be reduced if the array faces significantly away from the south.

There are many different ways of mounting a solar PV system. Generally, a 1kWp system requires approximately 8m² of roof space. If there is not enough room to mount a PV system on your roof, then Dulas would recommend a ground mounted PV system if space permits.
