Introduction

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.

DISADVANTAGES

  • 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.


Advantages

  • 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.
