Wind Turbines


Below gives an idea whether a photovoltaic system is suitable for your premises. Greenheart’s photovoltaic experts will work with you to design a system that would suit your specific requirements.

A Southerly facing roof

Being due south will give the best possible performance of the modules, although within 45 degrees of south would be considered suitable.  The roof will need to be pitched, between 15 – 50 degrees, with the optimum performance at around 33 degrees.

In the event of a flat roof, A-frames are used to mount the modules on and can be pitched and oriented to suit.

It is also possible to install photovoltaic panels on a “stand-alone” structure. This can be orientated and pitched for the best performance.

Minimum overshadowing

The performance of a photovoltaic system is affected by the amount of the sun’s energy received. As such, overshadowing (trees, buildings or other obstacles) should be kept to a minimum. Although the orientation of the roof might be ideal, if it is overshadowed, then the system’s performance will reduce.

At least 10 mtrs² of roof space

This will accommodate a system of around 1kW peak, which would be the minimum size Greenheart would install. The larger amount of roof space, the larger the photovoltaic system. Greenheart will work with the Customer to understand the best system to suit.

Do I need Planning Permission

In England and Scotland, changes to permitted development rights for renewable technologies introduced on 6th April 2008 and 12th March 2009 respectively, have lifted the requirements for planning permission for most domestic microgeneration technologies.
The General carol burnett nude pokies Permitted Development Order (GPDO), or the Town and Country Planning (General Permitted Development) (Domestic Microgeneration) (Scotland) Amendment Order 2009 grants rights to carry out certain limited forms of development on the home, without the need to apply for planning permission.

Roof mounted:
Photovoltaics are permitted unless the panels protrude more than 200mm when installed.

Stand alone:
Photovoltaics are permitted as long as:
• more than 4 metres in height
• installed less than 5 metres away from any boundary (England Only)
• above a maximum area of array of 9m2
In England only:
• situated on a wall within any part of the curtilage of the dwelling house and would be visible from a highway in Conservations Areas and World Heritage Sites.
Additionally in Scotland only:
• installed a distance from the boundary of the curtilage of the dwelling house which is less than the height of the array
• within the curtilage of a listed building
• results in more than one free standing solar
• The building is within a conservation area or World Heritage Site and the solar PV or is installed on a wall or roof which forms the front of the building and is visible from the road.
• Note additionally in Scotland only: The solar PV equipment must, as far as is reasonably practical, minimise its effect on the amenity of the area and be removed when it is no longer needed or used for domestic microgeneration.

For larger commercial projects it is normally a requirement to get in contact with the local planning department to discuss the project and understand whether permits are required.
