Solar energy is the light and the heat from the Sun. This energy is free, unlimited and, it doesn’t cause any pollution, which makes it the perfect source of power. With the availability of very low priced easy to install DIY solar systems, certainly, there has never been a better time to take advantage of this remarkable, infinite energy source.
There are lots of ways in which we are able to harness the power of the sun. In warm countries for example, solar furnaces are able to be used as means for cooking food. A solar furnace is merely a huge array of mirrors used to concentrate the Sun’s power into a small area and produce quite high temperatures. They are generally referred to as solar cookers.
The movie ‘Race the Sun’ was a story concerning low- income and under achieving Hawaiian students, advised by their teacher to join the Solar Car Race. In the movie, an automobile the same shape as a cockroach and covered with solar panels utilised the Sun’s rays as an alternative source of energy to run the vehicle.
Since Roman times we have been using the Sun as an effective method of obtaining electric power. Nowadays nonetheless we have created solar thermal solutions which are put to use for water heating, space heating, space cooling and process heat generation. Solar technology is also used to distil water and even transform saline or brackish water into something that is drinkable. Solar water disinfection or SODIS as it’s commonly known, involves subjecting water-filled plastic polyethylene terephthalate or PET bottles to the Sun, whereby UV-radiation kills diarrhoea generating bad bacteria. The SODIS-method helps to defend against diarrhoea and and in so doing is saving lives of people. In excess of 4000 children die each and every day from the effects of diarrhoea. This technique does rely on climate conditions, but given that the most crucial demand for water is located in hot countries this is when this system is most effective. Currently, you will find in excess of two million people in developing countries who rely upon SODIS for everyday drinking water needs.
Daylight systems are also being used to optimize the power emitted by the sun. A Daylight System is used to provide interior illumination, thereby replacing the need for artificial lighting. Daylight systems include things like sawtooth roofs,, skylights, and light tubes. Where daylight systems are correctly implemented they’ll reduce lighting-related energy consumption typically by 25 percent.
One of the fastest growing areas regarding the utilisation of solar power is in the use of photovoltaic or PV panels which can be used to convert the sun’s rays directly into electricity. To start with solar energy was only utilized to power modest appliances and equipment, such as calculators that are powered by way of a single solar cell. Even though water and space heating tend to be the most commonly used applications of solar energy, the advancement of photovoltaic technology now means that a lot more families are using solar energy to supply either a significant percentage or even all of their energy needs.
One of the main concerns associated with the usage of solar energy with regard to domestic properties has been the expense of fitting such a system. Several thousand dollars were required simply to pay for installing a fairly modest system. Today however, the availability of DIY solar energy materials, and indeed complete kits, has meant that superb systems can easily be installed for mere 100’s of dollars.
