Advantages and Disadvantages of SOLAR ENERGY

Posted by admin on August 28, 2012 in Clean Energy with 3 Comments

Many of us know that solar energy is good, but few really
understand why.

Therefore, I compiled a comprehensive list of solar energy
advantages and disadvantages that will enable you to make an
educated decision whether on not Solar Power is right for YOU.
Solar Energy Advantages

1. Saves you money

  • After the initial investment has been recovered, the
    energy from the sun is practically FREE.
  • The recovery/
    payback period for this investment can be very short depending
    on how much electricity your household uses.
  • Financial
    incentives are available form the government that will reduce
    your cost.
  • If your system produce more energy than you
    use, your utility company can buy it from you, building up a
    credit on your account! This is called net metering.
  • It
    will save you money on your electricity bill if you have one at
  • Solar energy does not require any fuel.
  • It’s not affected by the supply and demand of fuel and is
    therefore not subjected to the ever-increasing price of
  • The savings are immediate and for many years
    to come.
  • The use of solar energy indirectly reduces
    health costs.

2. Environmentally friendly

  • Solar Energy is clean, renewable (unlike gas, oil and
    coal) and sustainable, helping to protect our environment.
  • It does not pollute our air by releasing carbon dioxide,
    nitrogen oxide, sulphur dioxide or mercury into the atmosphere
    like many traditional forms of electrical generations does.
  • Therefore Solar Energy does not contribute to global
    warming, acid rain or smog.
  • It actively contributes to
    the decrease of harmful green house gas emissions.
  • It’s
    generated where it is needed.
  • By not using any fuel,
    Solar Energy does not contribute to the cost and problems of the
    recovery and transportation of fuel or the storage of
    radioactive waste.

3. Independent/ semi-independent

  • Solar Energy can be utilized to offset utility-supplied
    energy consumption. It does not only reduce your electricity
    bill, but will also continue to supply your home/ business with
    electricity in the event of a power outage.
  • A Solar
    Energy system can operate entirely independent, not requiring a
    connection to a power or gas grid at all. Systems can therefore
    be installed in remote locations (like holiday log cabins),
    making it more practical and cost-effective than the supply of
    utility electricity to a new site.
  • The use of Solar
    Energy reduces our dependence on foreign and/or centralized
    sources of energy, influenced by natural disasters or
    international events and so contributes to a sustainable
  • Solar Energy supports local job and wealth
    creation, fuelling local economies.

4. Low/ no maintenance

  • Solar Energy systems are virtually maintenance free and
    will last for decades.
  • Once installed, there are no
    recurring costs.
  • They operate silently, have no moving
    parts, do not release offensive smells and do not require you to
    add any fuel.
  • More solar panels can easily be added in
    the future when your family’s needs grow.

Solar Energy Disadvantages

  • The initial cost is the main disadvantage of installing
    a solar energy system, largely because of the high cost of the
    semi-conducting materials used in building one.
  • The
    cost of solar energy is also high compared to non-renewable
    utility-supplied electricity. As energy shortages are becoming
    more common, solar energy is becoming more
  • Solar panels require quite a large
    area for installation to achieve a good level of
  • The efficiency of the system also relies on
    the location of the sun, although this problem can be overcome
    with the installation of certain components.
  • The
    production of solar energy is influenced by the presence of
    clouds or pollution in the air.
  • Similarly, no solar
    energy will be produced during nighttime although a battery
    backup system and/or net metering will solve this problem. See
    www.dsireusa.org for details on how net metering allows you to
    save electricity and money.
  • As far as solar powered
    cars go – their slower speed might not appeal to everyone caught
    up in today’s rat race.

    (1) lower marginal cost for increasing energy production (you don’t have to build a new coal fired facility to achieve a small increase in power production);
    (2) fewer issues with greenhouse gas production
    (3) distributed power production;
    (4) some independence from the grid.


    (1) dependency on insolation (it works better in Arizona than in the Yukon);
    (2) initial installation cost for individual homeowner (but this is changing with new financing methods);
    (3) sensitivity to weather
    (4) it may require neighbors to be cooperative by not growing trees that block rooftop solar arrays;
