Thermal Solar: Using Heat From The Sun.
Thermal solar technology uses the sun to
heat water or air to produce heat or
electricity.
Examples of thermal solar are hot water
heating and food drying.
Newer technologies are experimenting with
ways of using heat from the sun to generate
electricity.

3. Second Page : Solar Hot Water
Solar hot water
Solar hot water systems work with your existing gas or electric hot
water service. Water is heated in a rooftop solar collector and piped
into your hot water service.
There is no need to worry on cloudy days, because your hot water
service will ‘top up’ the heat by using gas and electricity, to the desired
level – so you’ll always have water at the right temperature.
The solar collector is usually located on the roof facing the sun.
Sunlight heats an absorber plate in the collector and this heats the
water running through tubes inside the collector.
The heated water is pumped or moved by gravity into your gas or
electric service tank.
Solar water heaters use much less electricity or gas to produce the
hot water you normally use.
Typically, solar can provide about 60% of the energy needed to
provide household hot water.

– Thermal Solar In The Future
There are many experimental thermal
solar technologies that generate
intense heat or drive power plants.
Solar concentrators use mirrors or
reflectors that focus the sun's rays to
produce maximum heat, which then
creates steam that drives a generating
turbine (similar to a typical gas or coal
fired generator).
Solar chimneys or towers are another
experimental use of thermal solar.
Heated air rises in the chimney turning
a mill. The mill then turns a generator,
producing electricity.

6. Fifth Page :
– Solar Desalination
Solar energy can be used to power
desalination or water purification.
Solar desalinisation, purification
and pasteurisation all use the sun
to heat water.
Using the sun to take the salt out
of water is called ‘solar
humidification’. This process
mimics the natural water cycle i.e.
heat evaporates salty water which
then condenses without the
impurities (salt) as water
droplets.
