Energy harvesting is also known as power harvesting

o Energy harvesting is the process by which energy is derived from external sources EXAMPLES:oSolar power oThermal energy oWind energy etc.

WHY SOLAR?

It’s free

It’s clean

It’s infinitely

renewable

It can reduce

your utility

costs

It increases

your energy

self-reliance

It comes with

incentives

It can also

increase your

home’s value

It’s

extremely

reliable

?

FACT!

It provides approximately 1,000watts of power that hits Earthin just two hours is more thanenough to meet current globalenergy consumption for an entireyear.

HOW CAN WE MOST EFFECTIVELY CAPTURE,CONVERT AND STORE THIS

TREMENDOUS NATURAL RESOURCE?

SOLAR CELLS

Solar cells also known as Solar Photovoltaic cells or Photoelectric cells.These cells convert the solar radiation into D.C electricity ,which can be either used as it is or stored in the battery for use at night.Solar photoelectric cells can be used for domestic and street lighting, electrification of salty water as well as satellites on outer space.

EXAMPLES:Calculators Watches Satellites Electric lightsRadios Highway lighting Weather stations Solar cookers Solar furnace Solar power plants Solar water heater

SOLAR WATER HEATERS

Solar water heaters can be installed on the roofs of the houses It consists of a glass panels with water pipes

When the sun’s radiation strikes the panels and the pipes , the sun rays warms the water for use in homes and offices.

Solar Steam cooking Systems

This system employs a large number of solar concentrators to trap solar energy to produce steam for use in large scale cooking in community kitchens.

Solar Pump SetsThe solar pump sets operate on power generated using solar photovoltaic cells.The system is used to lift water from bore or open well or water reservoir for irrigating the agriculture fields and drinking water purposes

SOLAR DRYERS

The device is used for :drying of agricultural crops dehydration of fruits and vegetables in food processing industries production of milk powder and casein in dairy industry seasoning of wood and timber drying of textile materials in the textile industries

SOLAR STILL

The device is used in desalination of brackish of saline water to get potable water for use in industries , hospitals laboratories , homes etc

Darmstadt University of technology in Germany won the 2007 Solar decathlon in Washington , D.C. with this passive house designed specifically for the humid and hot subtropical climate.

Hope for a better

Solar future…..…..
