Time for Change
Solar power has been available for decades. Safe, relatively clean energy, but the cost of the panels has long been too high for the average consumer. They’re also the one problem with solar energy, for those wondering about the relatively clean energy part. But the recycling of them should improve over time.
Advantages and Disadvantages
The use of solar energy is versatile; it is used for electricity, central heating, hot water, cooking, for producing salt and even for desalination. The energy comes from the sun’s rays and is known to be very environmentally friendly. However, when the sun rays enter the earth’s atmosphere it is quite dilute. Although the advantages are clear there are also disadvantages.
Let’s start with the biggest advantage; it is a clean form of energy. To produce electricity or heat you only need the sun rays. There is no need to use fossil fuel in combination with sun rays to produce electricity or heat. You just need a solar energy collector or solar power panels in order to convert the energy into electricity.
Another advantage is that it is cheaper than to use traditional electricity for heating. If you are using traditional electricity for heating you can save a lot of money. In return you will get lower electric bills and it also means that you don’t have to maintain heaters.
If you live in a remote area where there are no power-lines solar energy can be the solution. There are remote areas where power companies have no means to access your home. This great alternative can provide you with anything from heating water, electricity, and even cooking.
Another great use is for desalination in areas where fresh, drinkable water is scarce. The brine is evaporated and leaves the salt crystals in the bottom of the basin. The water in turn condenses back in another basin where it is now drinkable.
The advantages mentioned above are tremendous but there are some disadvantages. These disadvantages also need to be discussed to paint a better overall picture.
The main disadvantage of solar energy is that it’s dilute. This means you have to have a lot of solar collectors installed around your house. The energy itself is free, but the solar collectors are relatively expensive and some require regular maintenance in order to work properly and efficiently. If you decide to go solar you need to calculate the return on investment in order to know if the investment will be worth it.
One big disadvantage is that you need the sun rays to make use of it. If you are situated in a part of this beautiful planet where there is not much sun light then this could be a problem. In other areas, the sun rays are almost always covered in clouds making solar energy collectors less efficient. You should first know if the sunshine in your area is abundant for the most part of the year. Of course if you live in desert areas like in Arizona or Mexico the sun produces a lot of sunshine for the most part of the.
Lastly the sun only shines during the day. Therefore if you need electricity or hot water during the night, like many of us do, it can be a problem. You will need a backup system like the ‘old’ utility grid or you will need to store the electricity for later use. There are battery systems that can store solar energy for later use. The hot water collected during daytime is often stored in a tank for later use. The modern systems are becoming more sophisticated in storing electricity or hot water. If you are still using your grid, the produced electricity can be pumped back into the grid.
Solar energy is very clean and is a good alternative for traditional electricity. Although this is true it is also good to mention the disadvantages. If you are considering using solar energy you must read this first to make a balanced decision.

Varieties of Solar Power
Solar power involves harnessing the power of the sun to produce light and heat for buildings and homes. With today’s rising fuel costs, many people are turning to this alternative source of power as a means of heating their homes. The initial cost of setting up such as system may be more expensive, but the long- term costs are much less expensive.
You already have experience using solar power, even though you may not realize it. Calculators that will operate without batteries as long as they are close to a light source are very common examples. Greenhouses rely on solar power to help the plants to grow. They are usually constricted of translucent plastic that harnesses the power of the sun and transforms it into the heat and light that plants need.
Solar Panels
This use of the sun is not a modern idea. Thousands of years ago the Anasazi peoples used the same technology in their cliff dwelling homes. Adobe homes are another example of how people have used the power of the sun throughout history. Today this age old technology is called passive solar heating. It simply means that the heat from the sun is collected and distributed throughout a home with using any means of pumping it through.
There are several different ways of collecting and using power from the sun for your daily needs:
1. Photovoltaic Solar Tiles – These are special tiles that are used on the roof of a house to take full advantage of sunlight. The tiles are the material used for the roof covering and the cells in these tiles trap the sunlight and transform it into electricity.
2. Specially designed buildings – Buildings can have a special design in order to collect the heat radiated by the sun. They usually face toward the sun in order to take full advantage of every second of daylight. There are large glass windows in every room and in summer, balconies and large trees are used as shade to prevent the entry of too much of the sun’s heat during the day.
3. Heated Water Pipes – Using the heat from the sun to heat water pipes that run throughout the house is becoming the common method of using solar power. The pipes are painted black and placed in a type of greenhouse that will absorb the heat from the sun. This helps to keep water hot without having to use electricity. Having the pipes running through each room allows the solar power to heat the house in a manner similar to radiation heating systems. These are panels placed on the roof of a home to collect the heat from the sun.
4. They are designed to maximize the light and the heat and in so doing cut down on fuel costs for the homeowner.
Many countries of the world are beginning to realize the effectiveness of solar power, not just in terms of fuel costs, but also in the fight against pollution. There are no fumes or pollutants being released into the air with using solar power.

Is Solar Power the Future?
Solar power has been available for decades. Safe, relatively clean energy, but the cost of the panels has long been too high for the average consumer. They’re also the one problem with solar energy, for those wondering about the relatively clean energy part. But the recycling of them should improve over time.
Many people would love to go solar in their homes. It’s a practical energy source in many places, even ones where you wouldn’t expect it to do all that well. And in places where homes aren’t built near a pre-existing grid, solar power is often much, much more reasonable than having wires run out.
The fact that energy prices have been steadily rising also helps solar energy appear more reasonably priced. The cost is almost all upfront, which is perhaps the greatest challenge. A good solar power system sufficient to heat the average home in the United States runs many thousands of dollars. However it also offers tremendous savings over time.
Some people even generate enough excess to where they sell electricity back. It doesn’t bring in much money on the average, but you must admit that having the power company pay you has an appeal, especially if you aren’t paying them anything anymore.
Is solar power ready to take off at long last? It could be. We’ve been hearing for a long time that the day would come when solar power became affordable, something the average family could do, rather than something strictly for the affluent and environmentally aware.
States are becoming more interested in encouraging solar power as well. Many offer rebates or tax incentives to homeowners who install solar panels, and some are starting to look at businesses as well. May as well put those rooftops to good use, after all!
Unfortunately, not all states do this yet. It sounds like they will soon! There is federal legislation requiring states to consider adopting net metering standards by 2008. How this works from state to stat can be tricky, but since 40 states already have net metering, which allows customers to sell excess electricity back, paying only when they need more than they produce, things are looking better all the time.
Solar power is starting to fare better politically too. While it still lacks the funding of the coal or oil industries, it has popular backing. That does make a difference.
Choosing solar power still isn’t the easiest thing. As with other home improvements there’s a lot of paperwork, plus finding a reputable contractor with good solar panel installation experience. But things are definitely looking up.
