o Flexible Solar Panels

4. Solar Water Heater
“Device which use to heat water using solar
energy”
 Storage tank Solar Collector
History
Tubes
Efficiency
Cost

5. Solar
Dryer
Direct
Dryer
Indirect
Dryer

6. Direct Solar Dryer
“Direct Solar Dryers expose the substance
to be dehydrated to direct sunlight”
In this Dryer the solar drying is assisted by
the movement of the air (wind) that
removes the more saturated air away from
the items being dried

7.  Solar Natural Dryer
 Cabinet type Solar
Dryer
 Solar Tunnel Dryer
 Green House Solar
Dryer

8. Indirect Solar Dryer
In indirect Solar Dryers, the black surface heats
incoming air, rather than directly heating the
substance to be dried
Transpired collector
type Hybrid
(Solar-biomass) Dryer

9. Solar PV Panels
“A solar cell, or photovoltaic cell, is an electrical device
that converts the energy of light directly
into electricity by the photovoltaic effect”

10. Solar Cooker
A solar cooker is a device which uses
the energy of direct sunlight to heat,
cook or pasteurize food or drink

11. Solar PV Cell
Photovoltaic cell, is an electrical device that converts
the energy of light directly into electricity by the
photovoltaic effect

18. Analysis Lab
 The Spectroscopic analysis of the
semiconductor and other
geological materials is done for
detection of metallic and non
metallic impurities up to the level
of parts per million (PPM) and
parts per billion (PPB) level
 ICP detects impurities using
options of Atomic Absorption,
Atomic Emission and Flameless
Techniques
 Gas Chromatograph GC analyses
gases using FID and TCD
detectors
Inductivity Coupled Plasma (ICP) Spectrometer
Gas Chromatography (GC)
