“Solar Radiation and its Effects on Planet Earth” The Sun emits a tremendous amount of energy‚ in the form of electromagnetic radiation‚ into space. If we could somehow build a gigantic ball around the Sun that completely enclosed it‚ and lined that ball with perfectly efficient photovoltaic solar panels‚ we could capture all of that energy and convert it to electricity and be set in terms of Earth ’s energy needs for a very long time. Lacking such a fanciful sphere‚ most of the Sun ’s energy

limited‚ nuclear energy is dangerous‚ and then there is solar energy: clean‚ abundant and safe. It is already used around the Earth to give energy to those huge satellites into orbit but also in the surface of the Earth to provide electricity to many houses or other structures in need of energy. Indeed solar energy may be the most important renewable source of energy for the moment. However installations allowing using the solar energy such as solar panels are still very expensive and space consuming

research. This investigatory project is concentrated on comparing the affectivity of solar powered light made from 3 different brands of bleach available in the market. Specifically‚ it is sought to answer the following question: 1. Can we use plastic bottles to make an alternative light bulb? 2. Is it as good as the electric light bulb? 3. Is it cheaper than the light bulbs nowadays? 4. What describes the solar powered light in terms of: a)intensity of light b) Duration of light

2.5 Aspects of Solar Cell Efficiency Most of the energy that reaches a cell in the form of sunlight is lost before it is converted to electricity. The usual efficiency of these systems ranges between 10% to 15%‚ though sometimes this efficiency increases to 30% and more. Certain physical properties affect the cell efficiency which we will briefly state. 1- Reflection: Studies show that untreated silicon reflects 36% or more of sunlight that strikes it. Chemically coating and texturing the surface

“Going green” has become increasingly popular. Solar panels are used throughout the world‚ but don’t produce nearly enough of the energy that they potentially could. The U.S. Department of Energy reports that the efficiency of current commercial solar panels hovers from 11-15%‚ making it costly to produce enough energy for the world’s needs. The main barriers to widespread adoption of photovoltaic technology are installation costs‚ low efficiency and the limited number of peak hours (maximum amount
