Solar power originates from the conversion of sunlight into electricity. This can either be done directly with the use of photovoltaic, or indirectly through concentrated solar power.
The first commercial solar power systems were first developed in the 1980s, with the 354 MW SEGS CSP installation as the largest solar power plant in the world. It is located in the Desert of California. On the other hand, the 80 MW Sarnia Photovoltaic Power Plant in Canada, is the largest photovoltaic plant in the world. Experimental approaches to solar power include concentrated photovoltaic systems, thermo voltaic devices, and space-based solar power.
Solar power is an alternating energy source, and is therefore not available at all times. As such it is supplemented by a storage unit or another source of energy, ranging from hydropower and wind power.
Solar power systems are gradually gaining popularity in thousands of homes today because it is cheap and environment friendly. Thus users of solar energy are not only to save on money but also the environment especially at this time when the ozone layer is at threat of total depletion.
Solar power for homes contributes towards saving the environment by making use of solar energy obtainable from the sunlight which is an inexhaustible source of energy.
Another great advantage of using the solar power system is that they do not create harmful emissions and therefore they do not contribute to the depletion of other resources compared to the fossil fuels that are used to create power. Besides being a source of energy home owners use solar energy as a way of creating money savings.
However before purchasing solar power systems a few things must be considered. One such thing is the location; this refers to the geographic location of the home- usually based on the distance from the equator. Another aspect of location however is the specific area where the solar panels will be fitted within the home.
To achieve the desired results, the solar power systems panels should be placed facing the solar south which is somewhat different from the magnetic south. While the magnetic south is determined by a compass, the solar south is determined by the path of the sun. Though not perfect, an angle within 30 degrees of magnetic south is also satisfactory.
In Australia, the government offers a solar rebate for solar hot water units when replacing an existing hot water electric system. This has made the decision to switch to solar hot water systems more affordable than ever.
The government rebate is accessible by both property investors and owners who are keen on replacing existing electric system. This is applicable to both the heat pump and solar hot water systems.
The hot water solar rebate is non means tested with a thousand dollars and is available to investors, owner occupiers and tenants when replacing a previous electric hot water unit. These rebates are designed to be claimed by the client though Medicare.
