Solar Power and Wind Power

Home wind turbines can be a good alternative to solar power, but probably achieve their best when implemented together with a solar system: a small wind turbine can generate electricity in a breeze even when the sun is not shining.

Small wind turbines do have disadvantages however, and are very site specific. Compared to large wind turbines used by the power companies, small wind turbines are not particularly efficient and need to be situated in an area of above average wind in order to generate reasonable amounts of power.

If you live on a windswept farm or close to the coast, a wind turbine can work well. If you live in a built up area or close to trees or main roads you will find a wind turbine unsuitable for your needs.

If you are planning to install a small wind turbine in combination with a solar electric system, a smaller wind turbine that generates a few watts of power at lower wind speeds is usually better than a large wind turbine that generates lots of power at high wind speeds.

Grid tied solar power systems are solar power systems connected directly into the national utility grid. During the day, when the sun is shining, instead of storing the electricity, excess electricity is sold to the electricity providers and used elsewhere. During the evening and night, when the solar panels are not providing sufficient power, electricity is bought in from the national utility grid as required.

Grid tied solar power systems effectively create a micro-power station and electricity can be used by other people as well as yourself. Owners of grid tied solar power systems get paid for each kilowatt of power they sell to the electricity providers.

Because a grid tied solar power system becomes part of the national utility grid, the system will switch off in the event of a power cut6. It does this to stop any electricity flowing back into the grid – which could be fatal for engineers working on repairing the fault.
