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.
