Solar energy is radiant energy emitted by the sun. There are many disadvantages and advantages of solar energy. It also has an impact on the environment and on the economy.


  • Solar energy can not be used in the night, during storms and on cloudy days.
  • Solar cells and solar panels tend to be costly when you first purchase them.
  • For big companies to have a solar panel, will take up lots of space.
  • Some of the sunlight gets wasted and is not harnessed.


  • Solar cells do not make any noise.
  • Solar energy does not produce any pollution.
  • Most systems have a life span of 30-40 years.
  • Most systems carry a full warranty of 20-30 years or more.
  • No carbon footprint.
  • Is renewable.
  • Easy to install.

Environmental Impacts

  • Heat that is produced from a solar heater can replace energy that is produced in more polluting ways.
  • Usually the solar collecter is mounted on top of a roof, in which case there is no local impact on the environment.

Impacts on the Economy

  • The market in US for PV is expected to be around $27 billion dollars.
  • By 2020, according to the Department of Energy, this will directly and indirectly create 150,000 new jobs.
  • A recent study has been able to show that the cost of producing Ontario's solar energy will cost less per month and for households.
  • Solar power offers more jobs depending on the money invested than any other energy source, which creates more opportunities for jobs and the industry.
