    Default Solar Energy Advantages And DisAdvantages

    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 all.
    • 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 gasoline.
    • 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 future.
    • 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 price-competitive.
    • Solar panels require quite a large area for installation to achieve a good level of efficiency.
    • 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 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.

    Hi , the energy issue has become a significant issue in under developed as well as developed countries too , Solar energy is the positive one to utilize when you have no other option of generating the electricity through water,fuel etc.
    This is the good way of using the natural resources in the best way.
    Nice post and thanks for sharing.

    i have a 10Kw solar system on the roof of my house now, nets me a passive 10K a year tax free cashflow double the surface area in 3 years and they system pays for its self in 5, has a functioning life time of 10 year plus, hence on rough math at todays prices the unit will earn me about 100k over 10 years and pay for its self can not complain about a 200% return on a investment that requires nothing but a bit of sunshine and today's solar stuff is so good it is about 60% efficent even on cloudy days. it does help i live in a place that has loads of sunlight year round.

    Solar energy can be defined rather simply as the transformation of sun light into usable power. Now , solar power is used to provide electricity to homes, businesses, schools, colleges and also in space vehicles.
