Solar Jobs

Solar JobsSolar energy is the radiant light and heat from the Sun. Solar radiation

along with secondary solar resources such as wind and wave power,

hydroelectricity and biomass account for most of the available renewable

energy on Earth. Enough solar energy falls on the Earth every 40 minutes to

power the entire worlds energy needs for a whole year. Only a minuscule

fraction of the available solar energy is used.Solar power technologies provide electrical generation by means of heat

engines or photovoltaics. Once converted its uses are only limited by human

ingenuity. A partial list of solar applications includes space heating and

cooling through solar architecture, potable water via distillation and

disinfection, daylighting, hot water, thermal energy for cooking, and high

temperature process heat for industrial purposes.PhotovoltaicsPhotovoltaics (PV) is the type of technology and research related to the

application of solar cells for energy by converting sunlight directly into

electricity.Due to the growing demand for green sources of energy, the manufacture of

solar cells and photovoltaic arrays has expanded dramatically in recent

years. Photovoltaic production has been doubling every two years,

increasing by an average of 48 percent each year since 2002, making it the

world’s fastest-growing energy technology.At the end of 2007, according to preliminary data, cumulative global

production was 12,400 megawatts. Roughly 90% of this generating capacity

consists of grid-tied electrical systems. Such installations may be

ground-mounted (and sometimes integrated with farming and grazing) or built

into the roof or walls of a building, known as Building Integrated

Photovoltaic or BIPV for short.Germany was the fastest growing major PV market in the world during 2006

and 2007. In 2007, over 1.3 GW of PV was installed. The German PV industry

generates over 10,000 jobs in production, distribution and installation. By

the end of 2006, nearly 88% of all solar PV installations in the EU were in

grid-tied applications in Germany. The balance is off-grid (or stand alone)

systems. Solar hot water in Germany set record growth in 2008, with over

200,000 systems installed.In 2008 Spain became the solar photovoltaic market leader, with 2.6

gigawatts of new grid-tied installations.The concentrating solar power industry saw many new entrants and new

manufacturing facilities in 2008. India emerged as a major producer of

solar photovoltaics, with new policies leading to $18 billion in new

manufacturing investment plans or proposals.Solar ThermalSolar thermal energy (STE) is a technology for harnessing solar energy for

thermal energy (heat). STE is different from photovoltaics, which convert

solar energy directly into electricity.Passive SolarPassive solar technologies are a way of using sunlight for useful energy

without use of active mechanical systems. Such technologies convert

sunlight into usable heat (water, air, thermal mass), cause air-movement

for ventilating, or future use, with little use of other energy sources.

Passive cooling is the use of the same design principles to reduce summer

cooling requirements.Technologies that use a significant amount of conventional energy to power

pumps or fans are active solar technologies. Some passive systems use a

small amount of conventional energy to control dampers, shutters, night

insulation, and other devices that enhance solar energy collection,

storage, use, and reduce undesirable heat transfer.Passive solar technologies include direct and indirect solar gain for space

heating, solar water heating systems based on the thermosiphon, use of

thermal mass and phase-change materials for slowing indoor air temperature

swings, solar cookers etcActive SolarActive solar technologies are employed to convert solar energy into usable

light, heat, cause air-movement for ventilation or cooling, or store heat

for future use. Active solar uses electrical or mecha
