Solar Generated Electricity

Electricity can be generated from the sun in several ways. Photovoltaics (PV) has been
mainly developed for small and medium-sized applications, from the calculator powered
by a single solar cell to the PV power plant. For large-scale generation, concentrating
solar thermal power plants have been more common but new multi-megawatt PV plants
have been built recently.
A solar cell or photovoltaic cell is a device that converts light into electricity using the
photoelectric effect. The first working solar cells were constructed by Charles Fritts in
1883. These prototype cells were made of selenium and achieved efficiencies around
one percent. Following the fundamental work of Russell Ohl in the 1940s, researchers
Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954.
Photovoltaic growth rates jumped in 1997 and have since averaged 35%. Worldwide PV
installations now total approximately 10.5 GW as of year-end 2007. With many
jurisdictions now giving tax and rebate incentives, PV installations can pay for
themselves in five to ten years in many places. "Grid-connected" systems - those
systems that use an inverter to connect to the utility grid instead of relying on batteries -
now make up the largest part of the market. While the deployment of PV power
depends largely upon local conditions and requirements, most countries are taking an
interest in developing PV as one of their options for renewable energy supply.

Solar Power

Solar energy technologies utilize heat and light from the sun for practical ends.
Technologies that utilize secondary solar resources such as biomass, wind, waves, and
ocean thermal gradients are sometime included in a broader description of solar energy
but only primary resource applications are discussed here. These applications span
through the residential, commercial, industrial, agricultural and transportation sectors
where solar energy is used to make clean water, produce food, heat and light buildings
and generate electricity.
• Generate electricity using photovoltaic solar cells.
• Generate electricity using concentrated solar power.
• Heat buildings, directly, through passive solar building design.
• Heat foodstuffs, through solar ovens.
• Heat water or air for domestic hot water and space heating needs using solarthermal
panels.
• Heat and cool air through use of solar chimneys.
• Solar air conditioning.
