2. What is solar power?
● Solar power is made from the light
energy that comes from the sun.
● It is the conversion of sunlight into
electricity, either directly using
photovoltaics (PV), or indirectly
using concentrated solar power
(CSP).
● Concentrated solar power systems
use lenses or mirrors and tracking
systems to focus a large area of
sunlight into a small beam.
3. The solar rays from the Sun are quite important for the life on Earth.

5. Charles Fritts
Solar energy has been used for
centuries but the person who
invented the first solar cell to
convert sunlight into electricity was
Charles Edgar Fritts in 1838. He
was a world known watch maker,
author, and inventor of many things.
Fritts constructed a ‘selenium solar
cell’ that was similar, in some
respects, to the modern silicon
solar cell of today.

6. Ways to Gather Solar Power:
● Photovoltaic panels
● Thin-Film Photovoltaic
● Concentrated Photovoltaic
10. Why isn’t solar power commonly used commercially?
Solar power is not used commonly
in the world because the price of
gas is cheaper and it’s easier to
get, or literally, it’s right under our
feet.
