Solar Grid Tie systems

Solar Grid Tie systems utilise photo voltaic (PV) solar panels generally mounted on a roof to produce electricity. The light from the sun is absorbed by semi conductors in the panels such as silicon which excite the electrons; this in turn produces an amount of Direct Current which is then converted into alternating current through an inverter for use in your home or business.

Quick Facts about Solar Grid Tie System


Produces energy during sunlight hours.


Does not store energy unless a special system with batteries is also installed.


Requires electricity to work, ie they do not work in the event of a power cut.


Works on cloudy days, just less efficiently


Standalone Solar Power Systems are completely independent from any electric utility grid. They are most often used in remote areas where electricity is not available or where the connection fees of the grid are higher than the cost of an alternative energy system. Standalone solar systems (also known as autonomous, or off grid systems) are used to collect and store solar energy to be used by household appliances. These systems typically generate from 100 Watts (very small systems) to 5 kilowatts (larger systems, multi family homes). During the day, the electricity generated is used to power the home and charge the batteries. At night, and during rainy days, all necessary power is provided by the batteries.
Stand alone solar
In some cases, where it is important that power is always available, some stand alone
systems, known as PV-hybrid systems or island systems, may also have another source of power such as a wind turbine, bio-fuel or a diesel generator.
Power generated from a stand alone system is considered DC (direct current), and is stored in a battery and converted to AC (alternate current). Standalone Solar Power Systems are the perfect choice for remote rural to provide continuous reliable power.


New Zealand has excellent wind resources and increasing numbers of windfarms are being proposed and built. Small-scale and micro wind turbines are also available; for homes, farms and businesses that want to generate their own wind power.

Generally, small wind turbines are best suited to rural settings that are exposed to strong and consistent wind, and where there is no connection to the electricity network. Both these factors can help improve the economics of installing a small-scale turbine. For the same reasons, small wind turbines are less suited for use in urban areas.

Households normally usually use micro wind turbines that are smaller than 5kW. Small communities or groups of houses might use up to 20kW in size.
