According to Gevorkian (2007, p. 57), these hitches have led humans to seek alternative energy sources such as wind, wave, and solar energy. Solar energy is basically the energy derived from the sun. One way of harnessing this energy is through solar panels. Solar panels are simply devices that convert light energy into electric energy as noted by Mayer, Scully, Hardin, Rowell and McGehee (2007, p. 29). Another name for solar panels is photovoltaics which simply means light- electricity. Yet another name for the solar panel is solar module. More specifically, a solar module refers to a group of solar cells put together and packaged in a frame, and these can be grouped into larger arrays.
Even the most primitive generation of man was aware of the power stored in warmth of the sun. Some early uses of solar energy included home heating, solar cookers, and water desalinations. In the last couple of centuries, humans have been able to make great advancements related to harnessing the immense energy from the Sun. Though just a small percentage of the sun’s energy reaches the earth, it is still possible to create massive power plants that receive energy from it. In 1839 Alexandre Edmond Becquerel discovered how to explain the means by which photovoltaic effect can be used to create energy. The next century saw the development of solar cells, in 1921 Albert Einstein received Nobel price for his work on photovoltaic effects and in 1941 the first solar cells were invented by Russell Ohl (Energy Matters 2012; PRLOG 2009).
Solar cells are made of materials which are special in function known as semi-conductors. The most common material semiconductors are made of is silicon. When the semiconductor comes into contact with light, it absorbs a portion of it, meaning the light energy absorbed is transferred to the semiconductors (Nelson 2003, p 25). This energy causes a knock on the electron making them to move freely. There are one or more electric fields that force

It is already been given above the sky an enormous power source with clean and sustainable energy that is free at all cost. However, human still unwisely use their money and time seeking for oil and coal in order to produce something that will become a source of energy.
A long distance is covered to the surface as the energy transforms and is released as its primarily light energy, sunlight. The two forms of solar energy that make it to the earth are light and heat. Solar energy is often termed as alternative energy to the fossil fuel energy sources like oil and coal
Borshberg, who was the pilot, said that fitting a slow flying plan into a traffic system of commercial air is challenging. The pilot further said that flying from a place to another using the alternative sources of energy that is solar energy is quite symbolic.
In addition to being non-renewable, these sources of energies have been associated with environmental degradations and problems (House-Soremekun & Falola 2011). For example, according to Richards (2010) fossil fuels have been associated with air pollutions and global warming.
Over a couple of decades, the world population has increased by nearly two billion with a major contribution coming from the developing world (Devabhaktuni et al, 2013). This population growth in the developing nation’s, calls for an increase in methods of generating renewable energy.
Penstock- large pipe-delivers water to the turbine. The hydroelectric power can be produced from pumped storage, run-of the-river, tide, and underground power stations. It is worthy to note that hydropower
The challenge is that the sources of the non-renewable energy are rapidly exhausting and are not able to satisfy the future demand of energy (Rathore, 2010). The non-renewable sources of energy are expensive because they are obtained at clear-cut prices.
The author states that solar energy has many advantages in Hong Kong since there is abundant sunlight. High-rise and high-density urban environment often create difficulties for energy applications. There have been interesting results derived from using solar systems. Wind and solar energy have been proposed to be used in the "Hong Kong Disneyland”.
