Solar energy is radiant light and heat from the Sun
that is harnessed using a range of technologies such
as solar power to generate electricity, solar thermal
energy, and solar architecture.
The energy from the sun is quite capable of
fulfilling all the needs of humanity single
handedly. It releases an immense amount of
energy which can be put to good use. For
example- the sun provides us 1.7x 1022 J energy in
1.5days. This is equal to all the energy produced
by 3 trillion barrels of oil resources on earth.
Solar energy can be converted into heat,
electricity, or solar fuels. for example-solar energy
can naturally be converted in solar fuel by the
process of photosynthesis.

Electricity can be generated directly by solar
energy through PV cells or indirectly by
concentrated solar power.
Solar cells are systems that are composed of
semiconductor materials and which convert solar
energy directly into current. When light falls on
the device the light photons are absorbed by
semiconducting material and electric charge
carriers are generated.
Silicon is the most abundant element available on
the earth surface and mostly of the solar cells
fabricated using them

Overview
Solar power is a renewable energy source. It is available every day and can be harnessed in
different parts of the world. Unlike other sources of energy, solar energy will not run out.
As long as there is the sun, solar energy is accessible for us.
The increasing demand for energy, the continuous reduction in existing sources of fossil
fuels and the growing concern regarding environment pollution, have pushed mankind to
explore new technologies to produce electrical energy using clean, renewable sources, such
as solar energy, wind energy, etc. Among the nonconventional, renewable energy sources,
solar energy affords great potential for conversion into electric power, able to ensure an
important part of the electrical energy needs of the planet. Solar energy is free, practically
inexhaustible and involves no polluting residues or green gases emissions.
The electricity produced by solar energy is being used in telecommunication,
transportation, water heating, water treatment, agriculture, and the construction industry.

Agriculture
In arid lands where the water for agriculture is not readily available , the solar desalination process
has been applied to convert brine into fresh water for agriculture uses. In this process, the brine is
collected in a basin, and then solar energy is used to evaporate the water. This fresh water can be
used for agricultural purposes.
Solar Energy For Fuel Production
Enough solar energy reaches the Earth in 1 hour to fulfill the energy needs for human beings for 1 year.
However, because the PV cells or CSP technology works only during the daytime, solar energy must be
stored in some forms. Another alternative for fuel production from solar energy is artificial
photosynthesis.

Cooking
In many countries, the fuel used for cooking comes from firewood. Replacing this energy with the help of solar
cooking can save the environment by saving trees. A solar cooking system has been established with the energy
storage capability. It consists of flat plate collectors, reflectors, and a working fluid, which usually transfers the
heat from the collectors for cooking goods.
Solar Furnaces
In a Solar furnace, high temperature is obtained by concentrating the solar radiations onto a specimen using a number
of heliostats (turn-able mirrors) arranged on a sloping surface. The solar furnace is used for studying the properties of
ceramics at extremely high temperatures above the range measurable in laboratories with flames and electric currents.
Heating can be accomplished without any contamination and temperature can be easily controlled by changing the
position of the material in focus. This is especially useful for metallurgical and chemical operations. Various property
measurements are possible on an open specimen. An important future application of solar furnaces is the production
of nitric acid and fertilizers from air.

Conclusion
The traditional power generation based on solar energy is generally considered to
be unsustainable in the long term, due to the inability cases and low power
efficiency. As a result, more innovations are introducing all over the world.
The electricity generation at night is the most critical innovative options. Based
on the current technology, solar energy technologies are in a cable to provide
adequate energy to rising energy needs, and when comparing with the
nonrenewable technologies. So, innovations are an essential factor in the solar
energy sector to develop it with maximum efficiency. So, this paper presents
innovative ideas and future views of solar energy technology. As a final word,
innovation is a panacea for solar energy technology for full filling the future
rising energy demand effectively.
