Solar Energy Advantages and Disadvantages
By Anita Van Wyk
Many of us know that solar energy is a good thing, 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.
A. Solar Energy Advantages:
- 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.
- 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.
- 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.
- 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.
B. 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 http://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.
