Download file to see previous pages SPV technology have enabled creation of large amounts of energy from solar radiation in addition to the reduction of the costs of purchasing solar PV panels. This technology has various advantages and disadvantages in its use with implications in its future developments as explained in the following sections.
The most significant advantage of the solar PV technology is that it produces environmentally friendly form of energy (Solanski, 2009). Solar cells produce silent and clean energy which illustrates the advantage of PV solar systems which do not produce harmful pollutants since they are only fueled by natural sunshine or solar radiation. In this regard, solar systems do not lead to depletion of natural resources and thus prevents endangering of human, animal and plant health (Goetzberger and Hoffmann, 2005).
In terms of space, the solar PV systems have an advantage of being installed on rooftops especially in small scale energy production. Furthermore, solar PV systems have a benefit of long life span with limited need for maintenance (Solanski, 2009). Solar energy is also cheap because it is a renewable energy which illustrates that there is no need importation of fuel as it is locally available and free. More importantly, the solar PV technology allows for building of PV systems of any size depending on the energy requirements, whether large scale or small scale and thus these systems are scalable (Energy weekly News, 2012).
Whereas the solar PV systems have been described as environmental friendly, it is important to note that there are some toxic elements or chemicals such as arsenic and cadmium which are used during the process of PV energy production. Nonetheless the environmental impact of these chemicals is relatively minor in addition to the fact that they would be controlled or managed through proper disposal and recycling (Solanski, 2009). Additionally, the solar PV technology presents with a disadvantage or significantly high cost of producing ...Download file to see next pagesRead More

Solar Energy

...Solar Energy Introduction Solar energy is energy that is obtained from the sun. The sun is known as a big ball of heat and light that results from the nuclear fusion at is core. This process releases energy that travels in an outward direction to the surface of the sun. 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...

...?Solar Energy in Arab Countries Most of the Arab countries have shown phenomenal and extraordinary development within a pace of few decades. Natural resources have always been doing wonders for a vast majority of the Arab countries. The way Arab countries have used oil to take their economies to the apogee of success is a potential example of this. In the recent times, more and more Arab countries are considering ways to become more environment friendly and greener. A very important idea of the Arab countries in the present age is to drive their plans of concentrated solar power (CSP). Two transmission projects and nine CSP plants with a total power of 1.2 gigawatts are expected to be...

...Solar Energy Solar energy, which is energy that is derived directly from sunlight, is the most common source of renewable power in use today. Solar energy is a welcome solution to the environmental degradation that is caused by the use of fossil fuels. Solar energy is captured by means of solar panels which normally vary in size and voltage. These panels are composed of unique cells which capture solar energy which is then used or stored in other devices for later use (Benduhn 4). Pros and Cons of Solar...

... Solar Energy Where Solar Energy Is Used. Solar energy is used all over the world to power buildings, devices,and all types of electrical machinery. However, not every region globally is fit for setting up solar stations or heat collectors. The part of the world with the greatest potential of solar energy is essentially between the Tropics of Capricorn and Cancer (Wheeland 2014). Figure 1: The global solar radiation distribution, or insolation, as of 2013 by Meteonorm (Wheeland 2014). Currently, the biggest user of solar energy is Germany, which has installed solar PV (photovoltaic) stations that generated 32,411 MW in 2013 (Wheeland 2014).
