In spite of the high cost of solar technologies and policy of government, investment in the solar power generation is the good pay off due to the noise free and pollution free solar energy.

2. • Solar power generation is the simply the
generating the energy from sun.
• Solar energy is the mechanism of generation
of solar energy with the help of technology
used to trap the sun’s energy and make it
usable for other purposes.
• Sun emit the energy in the form of
electromagnetic radiation and this energy is
converted into the thermal or electrical
energy on earth.

3. • Photovoltaic cells are also knows as solar
panels.
• It is usually installed on the rooftops.
• Photovoltaic cells are made up of
semiconductor materials like monocrystalline
silicon, polycrystalline silicon, copper indium
sulfide, etc.
• When sunlight falls on the cells, electrons
become loose and they flow through the cell
and generate electricity.

4. • Solar power plants implement the variety
of techniques to generate the solar energy
as a source of heat.
• This heat energy is used to run the turbine
and boil water to generate the electricity.
• This generated electricity is supply to the
residential and commercial areas.

6. • Solar power panels are mounted on the
rooftop to generate the solar power for
homes.
• To keep the building warm at night, big
windows are installed on the direction of
sun to consume the sunrays on the
absorbent materials present on the floor
and walls.

7. • Solar energy is the inexhaustible source of
energy.
• Solar energy is noise and pollution free.
• Solar energy can also be generated in the
night with the help of photo switching.
• Solar technologies are costly but, they give
good return on investment within a few years.
• Many countries including Japan, US, India are
investing in solar energy generation.
