Solar Energy - The NEED Project
solar energy provides less than 1% of the electricity we use, but it is growing each year as solar cells get used more. In the future, it could be a major source of energy. Scientists are looking for new ways to capture, store, and use solar energy more efficiently. Solar Energy

How Solar Energy Is Collected and Distributed
kcc.ks.govWhat is Solar Energy? We know solar energy as a source of light and heat. Solar radiation is radiant energy emitted by the sun in the form of electromagnetic waves. The sun emits a vast amount of solar energy, but once that energy begins to travel through the Earth’s atmosphere, the solar rays are absorbed by ozone,

In other words, if one square meter were available for conversion of solar energy to electricity (at 100% efficiency), the energy produced would be sufficient for just two or three light bulbs. The challenge of solar energy utilization is to concentrate it.
Basics of Solar Energy - Centre for Science and Environment
cdn.cseindia.orgThe solar rating is a measure of the average solar energy (also called “Solar Irradiance”) available at a location in an average year. Radiant power is expressed in power per unit area: usually Watts/sq-meter, or kW/sq-meter. The total daily Irradiation (Wh/sq-meter) is calculated by the integration of the irradiance values (W/sq-meter).
