How to supply humanity with electricity without harm to the environment is the main question that modern researchers asked not so long ago. We have already learned how to extract solar energy by building wave, tidal, geothermal, wind and solar power plants. The progress of technology has given us a unique opportunity to use the Sun with the help of an installed system or portable batteries for individual purposes. In this article, we will look at the pros and cons of Solar energy in Australia, as well as briefly talk about what solar panels are and where they are used.
Solar battery device
The possibility of using solar energy was given to us by such a science as solar energy. It is she who researches and develops devices that convert solar radiation into electrical and thermal energy.
Such devices include a solar battery. This is a flat, with a protective coating construction of photocells, which are semiconductors. They provide the process of converting solar energy into electrical energy. Due to the variety of sizes, they are used in various areas of life.
For example, to provide electricity to a private house, you will need an installation that includes the following components:
With the help of an inverter, the direct current, which is created on a clear day, goes through the process of converting to alternating current, and then distributed to electricity consumers. Unused electricity is stored in batteries and used at night or in bad weather. The controller monitors the charge of the batteries.
The use of solar panels has the following advantages:
- Availability of an energy source
- Constant and independent power supply
- Free consumption
- Environmental friendliness
- High wear resistance
We will describe each of these advantages in more detail.
Availability of energy source
The sun illuminates almost every part of the Earth’s surface. Therefore, a person can take advantage of the use of solar energy. It should also be noted that the potential of this type of energy on a global scale many times exceeds the need for it.
Permanent and independent power supply
Unlike minerals, the energy of the Sun is inexhaustible and all-encompassing. Of course, like everything on our planet has its end, so the Sun can dry up. But when that will happen, no one knows for sure. In addition, neither the solar panel nor the source itself requires any maintenance costs. This fact makes you independent from the prices and transportation of electricity supply.
As we have already mentioned, the Sun is a source of free energy. Some costs will be required only for the installation of a system that will provide you with electricity. But in this case, they can be attributed to long-term investments.
Global warming is a serious problem. The use of Solar manufacturer in Australia helps to reduce the consumption of natural resources, and their production and principle of operation are not accompanied by the emission of harmful substances into the atmosphere. Therefore, they are environmentally friendly.
When installing a system that converts solar energy into electricity, you can be sure that it is safe for the environment and your family and friends.
The generation of electricity is completely silent due to the absence of moving parts in the construction of solar panels. Installing the system on the roof of your house, you cannot worry about the constant hum, which, for example, is emitted by electric poles.
High wear resistance
The service life of such a power supply system is about 25 years. Over time, the efficiency of the panels begins to decline. In view of the simplicity of the design, it can always be replaced with a new one.
Disadvantages of using solar panels
Solar energy, namely its use, also provides for disadvantages, despite the above-described advantages.
The disadvantages include the following factors:
- High price
- Low efficiency
- Large area occupied by the system.
- Dependence of work on weather conditions
The cost of installing a system that can meet the individual needs of a person is prohibitive. Not to mention, to supply electricity to the whole house. This is explained in the next paragraph.
The productivity of solar panels is much lower compared to traditional sources of electricity. For example, a panel of average performance, with an area of 1 m 2, produces a power of about 120 watts. This should only be enough to charge your tablet or phone. This leads to the next point.
Large area occupied by the system.
To meet your minimum electricity needs, you will need a very large area. Unless, of course, we are talking about charging phones, tablets, or operating devices with low power consumption.
Dependence of work on weather conditions
The efficiency of solar panels decreases on a cloudy, cloudy day, in winter, at low temperatures, etc. At night, in the absence of the Sun, the source of energy, the production of electricity stops. Panel performance is also affected by the location of your home and windows.
Use of solar energy
In addition to meeting the individual needs of consumers of electricity, solar energy is used in various areas of life:
Aviation. Thanks to solar energy, aircraft can go without fuel for some time.
Automotive. The panels can be used to charge electric vehicles.
Medicine. Thanks to the developments of South Korean scientists, the world saw a solar battery, which is used for devices that support the functionality of the human body by implanting under the skin.
Cosmonautics. Solar panels are installed, for example, on satellites and space telescopes.
These are just a few examples. In addition, solar panels are widely used to provide electricity to buildings, as well as entire settlements.
