What are some advantages of Solar Energy?

•The power source of the sun is absolutely free.
•The production of solar energy produces no pollution.
•The technological advancements in solar energy systems have made them extremely cost effective.
•Most systems do not require any maintenance during their lifespan, which means you never have to put money into them.
•Most systems have a life span of 30 to 40 years.
•Most systems carry a full warranty for 20 to 30 years or more.
•Unlike traditional monstrous panel systems, many modern systems are sleeker such as Uni-Solar rolls that lay directly on the roof like regular roofing materials.
•In 35 states, solar energy can be fed back to the utilities to eliminate the need for a storage system as well as eliminating or dramatically reducing your electric bills.

Solar cells are long lasting sources of energy which can be used almost anywhere. They are particularly useful where there is no national grid and also where there are no people such as remote site water pumping or in space.
Solar cells provide cost effective solutions to energy problems in places where there is no mains electricity. Solar cells are also totally silent and non-polluting. As they have no moving parts they require little maintenance and have a long lifetime. Compared to other renewable sources they also possess many advantages; wind and water power rely on turbines which are noisy, expensive and liable to breaking down.
Rooftop power is a good way of supplying energy to a growing community. More cells can be added to homes and businesses as the community grows so that energy generation is in line with demand. Many large scale systems currently end up over generating to ensure that everyone has enough. Solar cells can also be installed in a distributed fashion, i.e. they don't need large scale installations. Solar cells can easily be installed on roofs which means no new space is needed and each user can quietly generate their own energy.

ADVANTAGES
1. Solar energy is free although there is a cost in the building of ‘collectors’ and other equipment required to convert solar energy into electricity or hot water.
2. Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution.
3. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid.
4. Many everyday items such as calculators and other low power consuming devices can be powered by solar energy effectively.
5. It is estimated that the worlds oil reserves will last for 30 to 40 years. On the other hand, solar energy is infinite (forever).

Solar power gives you a return on your investment, while paying your utility for electricity gives you 0% return. Solar energy is renewable unlike the conventional resources (coal, oil) which will inevitably run out. Non-polluting, no carbon dioxide like fossil fuels
Free except for capital expenses. Longevity - solar panels can last over twenty years. Low maintenance - solar panels require very little upkeep. Independence - an off-grid system allows you to break free from the electrical grid. Environmentally friendly because the conversion of energy doesn't produce any carbon dioxide. It comes from the sun, which, unless you are in The South or North pole, comes out almost everyday. Solar power is better for the environment, compared to burning fossil fuels and other electrical power.
We are using a renewable energy source like the sun, instead of non-renewable energy sources such as Gas, oil, fossil fuels etc. We can save power of electricity. We can prepare food with more taste. We need not bother about electricity board. Solar power panels are small enough to fit on every rooftop in a city. Solar cells last a long time, typically guaranteed for 20 or 25 years.
