benefits of solar power Frequently Asked Questions

The terms solar power and solar energy are often used synonymously but solar power usually refers to photovoltaic (PV) and concentrating solar thermal technologies that convert sunlight into electricity. In the case of solar PV, the process is direct, via silicon-based cells; in the case of concentrating solar thermal, the process involves heating a transfer fluid to produce steam to run a generator. While PV has advantages in terms of simplicity, the high temperatures produced by solar thermal systems also can provide process heat and steam for a variety of secondary commercial applications (cogeneration).

The utilization of solar energy ranges from traditional and basic technologies (related to food, heat and light) to modern, utility-scale power generation systems.

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. (visit www.dsireusa.org to find out about incentives available in the state you live in!).
* If your system produces more energy than you use, your utility company can buy it from you, building up a credit on your account! This nifty little scheme 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 generation 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.

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 independently, 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.

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 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.

Whats a good invention that could benefit the earth/decrease carbon foot print/etc.?

I am thinking of something like a solar powered car or almost waterless washing machine, but an ideas that have not been invented. Maybe a almost waterless dishwasher?

How about giant fans mounted on every other satellite that would blow cool air on the earth to reverse global warming. Then on the other satellites we could put giant vacuum cleaners on them to suck the pollution and green house gases out of the planet. This sounds like Nobel Peace prize stuff here baby !
