About 70% of the incoming solar energy reaches the Earth’s surface and is absorbed by land, the oceans and the atmosphere which raises their temperature. The circulation of the atmosphere is driven by warm, moist air rising from the oceans.
Solar energy is a complex and multifarious topic and one that is of pressing attention as the problems of providing energy for the world become more acute.
Various means for garnering energy from the Sun are presented, including photovoltaics (PV), thin film solar cells, quantum dot cells, concentrating PV and thermal solar power stations, which are more efficient in practical terms. Finally the prospects of space based (satellite) solar power are considered.
The studies found on photovoltaic solar energy are all technical, thus creating the need for future research related to the economic viability, chain supply coordination, analysis of barriers and incentives to photovoltaic solar energy and deeper studies about the factors that influence the position of such technologies in the market. 1.
At the equator, at sea level, and at noon on a clear day, the solar flux reaching the Earth is attenuated to 1,000 Wym2. If the performance of the solar cell were perfect (i.e. 100% conversion of radiation to electricity) an electrical output of 1,000 Wym2 (i.e. 1 kWym2) would be obtained.
Another method for utilizing solar energy is through the technology of concentrated solar power plants (CSPPs). These systems use mirrors or reflective lenses to focus sunlight on a fluid to heat it to a high temperature. The heated fluid flows from the collector to a heat engine for the production of electric energy.
