By having a look at both the positive and negative aspects of solar energy the intent of this work is twofold: to explain what solar energy is about and to show its meaning and potential in today's energy world.
Chapter 2 introduces the concept of renewable energy by roughly outlining the various possibilities and furthermore, gives a short overview on solar energy. The aim of this passage is to familiarize the reader with this technology.
Chapter 3 compares the advantages solar energy has to offer and the reasons for which this technology has become a success with the disadvantages and factors that argue against the use of solar energy.
Building on the aforementioned comparison, chapter 4 assesses the positive and negative criteria and concludes this brief analysis with an outlook on the future role of solar energy as an energy source.

Excerpt from the Book
3.1. Success factors
Solar Energy is one of the regenerative energy types and can boast with numerous advantages: The sun delivers its energy-rich radiation absolutely free to our planet earth and will continue to do so for many years. Contrary to fossil energy carriers the availability of the necessary raw material for energy production can be considered as permanent, inexhaustible and renewable – as far as is humanly possible to tell - even if we use it to the maximum. The abundance of solar radiation will last for some millions if not billions of years.
Whether solar modules for power generation are used or collectors for heat production, solar energy plants do not expel carbon emissions, i.e. there is no harm to our environment, to our climate nor to our health. Solar energy can therefore be called a very clean, environmentallyfriendly energy. If one concentrates more on the use of solar energy many existing environmental problems can drastically be reduced. Besides, all technologies related to the extraction of solar energy make absolutely no noise which makes it a very silent solution. If one uses them even the installation turns out to be comparatively easy and comfortable to employ.
Solar power panels are long-lasting products with an estimated life cycle of twenty to thirty years [7]. Unlike wind turbines which have moving parts, solar panels can simply be mounted and do not need much maintenance apart from the occasional cleaning of the solar cells. Apart from that, the panels are flexible objects which come in different sizes so that they can practically be put everywhere as long as they are exposed to sunlight. They can be mounted on roof tops, walls or even on the ground.
