3. About :
● Power Resources play a very important role in our daily
lives . This PPT will be throwing light on Non
Conventional sources. This article is about
radiant light and heat from the Sun that is
harnessed using a range of technologies. For
more detail about the generation of
electricity using solar energy, see Solar
power.

4. Types of Renewable Energy
● SOLAR ENERGY
● WIND ENERGY
● GEOTHERMAL ENERGY
● TIDAL ENERGY
● BIOGAS ENERGY
● NECLEAR ENERGY
IN THIS PPT topic is PROSPECTS OF SOLAR ENERGY

5. What is Solar
Energy ?
●Solar energy is any
type of energy
generated by the
sun. Solar energy can
be harnessed directly or
indirectly for human
use. These solar panels,
mounted on a rooftop
in Germany, harvest
solar energy and
convert it to electricity.
> Energy provided by
the Sun.
> Renewable
Energy

6. Origin of Solar Energy
In 1839 we encountered a major milestone in the evolution of solar energy: the defining of
the photovoltaic effect. At the age of 19, a young French scientist by the name of
Edmund Bacquerel discovered the photovoltaic effect whilst doing research in his father’s
lab with an electrolytic cell made up of two metal electrodes placed in an electrolyte. After
exposing it to light, energy increased. Willoughby Smith first described the “Effect of
Light on Selenium during the passage of Electric Current” in an article, first published in
the February 1873 issue of Nature. It was six years before the first solid state photovoltaic
cell was made by Charles Fritts. Fritts coated the semiconductor selenium with a thin
layer of gold to form the junctions. This device was only around 1% efficient. It was the
first to demonstrate that solid material with no moving parts could be used to convert
sunlight directly into electrical energy.

8. How Solar Energy Work
 STEP 1: Sunlight activates the panels. A rack-and-
panel solar system.
 STEP 2: The cells produce electrical current.
 STEP 3: The electrical energy is converted .
 STEP 4: The converted electricity powers your home.
 STEP 5: A net meter measures usage.
