¡ Solar energy is the ultimate source of energy from millions of years an
d it is a renewable energy.
¡ This energy consists of radiant light and heat energy from the sun.
¡ Just tiny fraction of the sun’s energy that hits the earth is enough to
meet all our power needs.
¡ Using present solar techniques some of the solar energy reaching the
earth is utilized for generating electricity etc….
¡ So the only option we have is solar energy because it is a nonpolluting
and silent source of electricity and also low maintenance and long lasting energy.
USES OF SOLAR ENERGY
• Heaters Green houses
• Cars water pumps
• Lights Desalination
• Satellites Chilling
• Dryers Solar ponds
• Calculators Thermal
• Commercial use
On an office building , roof areas can be covered with solar panels.
• Remote buildings such as schools, communities can make use of solar energy.
• In developing countries, this solar panels are very much useful.
¡
Low maintenance, long lasting sources of
energy
¡
Provides cost-effective power supplies for
people remote from the main electricity grid
¡
Non-polluting and silent sources of electricity
¡
Convenient and flexible source of small
amounts of power
¡
Renewable and sustainable power, as a
means to reduce global warming
Working of solar cells
• When solar panels are placed in the sunlight , photons will strike the surface and emits electrons.
• As a result electron hole pair is created in the solar cell.
• When external circuit is connected to the solar cell , electrons flow in the circuit and th e current is generated.
