What are the usefulness of solar power?

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).

Advantages of solar power are many. Although solar power is an energy source that we have only recently tapped into, it may easily become the most important energy source of the future. Solar energy can be used to heat water, dry clothes, heat swimming pools, power attic fans, power small appliances, produce light for both indoors and outdoors, and even to power cars, among other things.

Solar energy is becoming increasingly popular as the world begins to take notice of the burgeoning carbon emission problems that come with burning fossil fuels. But why all the fuss?
Disadvantages of Solar Energy
Solar doesn’t work at night. Obviously the biggest disadvantages of solar energy production revolve around the fact that it’s not constant. To produce solar electricity there must be sunlight. So energy must be stored or sourced elsewhere at night.
Beyond daily fluctuations, solar production decreases over winter months when there are less sunlight hours and sun radiation is less intense.Solar panels are bulky. This is particularly true of the higher-efficiency, traditional silicon crystalline wafer solar modules. These are the large solar panels that are covered in glass.

In solar systems connected to the electricity grid,
the PV system supplies electricity to the building,
and any daytime excess may be exported to the grid.
Batteries are not required because the grid supplies any extra demand.
However, to be independent of the grid supply,
battery storage is needed to provide power at night.

Money Saving - There are a number of a factors involved regarding how quickly your solar system will pay for itself including your specific energy needs and local climate. Ultimately however, today’s more efficient solar systems should help dramatically reduce or eliminate your monthly energy bill from anywhere from 50% to 80%. And in some cases, if your state has a net metering program you may even be able to sell your excess or unneeded power back to your local utility company.

Next, Increase House Value - like any home improvement, installing a solar system is a proven a way to increase the value of your home in the marketplace. Although in most cases it’s not practical to take them with you when you move, solar systems have no moving parts and can last for 30 to 40 years. According to some reports, a solar electric system can potentially increase a home's value by approximately $20,000 for each $1,000 in annual reduced electrical costs.

The last one, environment friendly - Solar energy is a renewable, efficient, and non-polluting energy source. Homeowners’who install a solar system can have the personal satisfaction of knowing they are helping reduce the emission of green house gases which most scientists agree have a direct relation to global warming.

One of the main disadvantages is the high cost of the equipment used to harness solar energy. Solar panels still remain a costly alternative to the use of readily available fossil fuel technologies. Although installing solar panels to your home requires a high upfront investment, solar panels will often pay for themselves over future years due to reduced energy bills and the possibility of selling excess electricity back to the grid.

The use of solar panel systems has become increasingly popular due to the financial savings they offer. Yet, this is just one good reason why you should look into adding them. They truly help to reduce the depletion of those resources we can't replace. As our society continues to move forward with advance technology, the amount of electricity being used everyday has been gradually increasing.
