Transcript of Solar energy
Solar panel historyIn 1839 Alexandre Edmond Becquerel discovered
the photovoltaic effect which explains how electricity can be generated from sunlight. He
claimed that “shining light on an electrode submerged in a conductive solution would create an
electric current.” However, even after much research and development subsequent to the
discovery, photovoltaic power continued to be very inefficient and solar cells were used mainly for the
purposes of measuring light.
Solar energy is energy from the sun.
Reaching the earth in the form of
radiation. It consist of heat and light
energy.
Signs of solar energy on Earth include:
The energy of fossil fuels, which originate in the distant past of planet or animal biomass.
• Coal• Oil• Natural gas
Solar House #1 of Massachusetts Institute of Technology in the
United States, built in 1939, used Seasonal thermal energy storage for year-
round heating
Future of solar energy
We think that people in future can
use mor then now solar system to
mek our planet better in better
condition
