Wind and Solar Homes
Both on and off the grid, wind or solar energy systems can help houses become energy self-sufficient. 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
Often a genset is sufficient for the house needs, but noisy, expensive to run, high on maintenance and inefficient when lightly loaded. Addition of a battery store, inverter/charger, changeover system 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. In many situations, solar power will be more relevant but larger wind turbines can be used to provide for greater load levels or heating.
Wind & Solar systems are all different; in some solar will be more relevant; in others larger wind turbines can be used to provide for greater load levels or heating.
Wind & Solar Remote Home Power Systems

On the Grid
No battery storage is required as 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.
Credits can be obtained either based upon electricity generated (whether used on site or exported to the grid) or simply for exported power. The exact scheme depends upon which electricity company supplies electricity to the property and what they offer. Different schemes for rewarding low carbon generation are constantly being introduced so it is often worthwhile to shop around and change to an electricity supplier who offers a good scheme for home generation.
See Sunny Boy & Windy Boy inverters which allow easy grid connection of wind or solar power.
Wind and solar on-grid home power systems
Almost any home with a south facing un-shaded location for a solar array can benefit with reduced electricity bills and a cleaner electricity supply by installing a PV system.
Those properties wiith good wind exposure can make use of wind power (not usually viable in built-up areas).
Installed costs start at approx. £6000.00 for a 1kWp PV system and £12,000.00 for 2.5kW wind systems.
