Solar panel systems for your home
Installing Solar Panels on my Home
The commonest way of mounting a solar array is to place it on the roof, with modules mounted in a frame above the existing roof tiles. Arrays can also be integrated into the roof; in this case PV roof tiles are used.
PV arrays can also be mounted on frames in a garden, or on flat roofs, walls, conservatory roofs, sun shades or other structures.
It is important that nothing casts a shadow over the area where the PV panels are mounted. PV panels generate more electricity on bright days but do not require direct sunlight, so normal daylight is sufficient to produce electricity.
The ideal orientation for PV panels is south facing, although orientations between south-east to south-west provide good returns. It is also possible to mount panel east or west if certain considerations are followed but the yield will be less.
There are two types of PV system that can provide energy for your home. You can have a grid-connected system or a stand-alone system. If your house is connected to the national electricity grid then the PV that powers your house will also be connected to the grid. If you live in a house that does not connect to the electric grid then you can operate a stand-alone system.
A PV array is rated in peak Watts (Wp). This is the output the array will produce at noon on a typical sunny day in Britain. A typical 4kWp system will meet about 40% of household electricity needs. PV panels come in various types – We can discuss your specific requirements when you contact us.
Solar panel planning permissions
Planning permission is not usually required for PV panel installation unless you live in a conservation area or listed building. Also, if you are grid connected you must seek permission from the electricity distribution company to install the panels with an output of greater than 10 kWp.
The average domestic system, costs between £3,500 and £6,500 with most domestic systems usually between 1.8 kWp and 4 kWp. An integrated Solar-tile installation costs more than conventional panel system. Conventional panels can be integrated into the roof area but these systems are slightly more expensive than the external mounted version. The most expensive systems use semi-transparent glass modules in facades or conservatory roofs.
To maximise the economics of the installation, you should use as much of the electricity you generate and export as little as possible to the grid.
This may entail behavioural changes such as putting on washing machines, dryers etc. during the day. If you can do this you will maximise the economic benefit.
