Answer to Question 1
Solar energy is electric power generated directly from sunlight through a device called solar cells which are made of silicon element and are usually connected in series formation to form a module. |
Answer to Question 2
On a on a cloudy day, solar panel will continue to harness energy from the sun because it does not depend on heat from sun, but on light from sun. Although on such cloudy day, the production of electricity is not as high as when the panel is exposed to bright sunlight.
|
Answer to Question 3
Definitely NO, since solar panel only convert light from sun to electricity when sun radiation impinged on its surface and when sun sets so also the output of the solar panel
|
Answer to Question 4
Batteries are the heart of any solar energy system. The batteries are capable of
acting as storage tank for the excess DC (direct current) energy converted by the solar panel during the day and store the excess energy for a later use, particularly at night when there is no sun
|
Answer to Question 5
Batteries can be recharged either directly from the solar panel during the day or by other power source (public utility or mechanical generator).
