By generating electricity on site using clean, quiet, reliable and sustainable technology the environmental impact of a building can be minimised.

Off the Grid

Wind and solar systems can enable homes to obtain complete independence from electricity bills and avoid the often heavy cost of bringing in the mains. A battery store is used to enable peak loads to be run and systems need to be designed to meet worst case weather conditions.

Best performance is obtained by practising energy conservation through choosing energy efficient appliances and minimising electricity use as well as matching use to times of generation wherever possible.

Remote Homes

Many homes in remote areas are beyond the reach of the electricity grid and would traditionally use a diesel generator for power. However, these can be noisy, expensive to run, high on maintenance and inefficient when lightly loaded.

Addition of a battery store and inverter/charger will compliment this to give minimum generator use and 24hr power ... including a wind turbine or solar array can eliminate the need for a generator altogether.

All loads can be run on conventional 230Vac wiring. Typically the requirements are for lighting (using low energy electronic compact fluorescents); TV; stereo; fridge; household appliances tools etc. all run from the inverter. Heating is usually by solid fuel and cooking from bottled gas. The generator is then only needed for occasional battery charges and to run heavy loads.

Wind & Solar systems are all different; in some solar will be more relevant; in others, wind turbines -or the two can be combined together.

On the Grid

SMA Sunny Boy Grid ConnectedWhere the mains is available wind and solar systems can simply hook into the conventional electricity supply reducing power requirements.

Power generated is used firstly by site loads and any surplus exported to the grid. This acts like an energy store supplying power in times when demand exceeds production. Power is still available at night or in times of unfavourable weather but greatest savings are obtained by matching electricity consumption to generation.

Power generated is first used within the property to reduce electricity consumption and any surplus is exported to the grid so greatest benefits can be found if electricity is used during times of generation.

Battery storage can be included to store surplus energy eg. from daytime to nighttime and so help increase 'self-consumption' of home generated electricity to make properties self-sufficient. Systems can also be set-up to provide back-up power in the event of grid failure.

Most Wind & Solar Home Systems require the involvement of a professional electrician to ensure a safe and compliant installation.

We work with a large network of installers, many of whom we have known for a long time and who have received training at Wind & Sun so we can usually recommend an  good local installer to you who can help.
