Solar Energy-The Advantages And Disadvantag


Perhaps the greatest argument that could be leveled about having to use fossil and nuclear fuel is our dependence on it. Global warming, though a real serious threat, maybe something that we could only be very worried about. Singly nothing much could be done about it as it will take serious political will if it is to be addressed effectively and for now, other countries are not cooperating. But the choice between traditional and alternative sources of energy, that is something most of us can choose to do.

First the advantages:

Solar energy is abundant and is free. We can count the sun to rise tomorrow and the day after that. Oil and natural gases on the other hand are non renewable, once the source taps out, it is gone forever. Sure there are other areas that could still be tapped but sooner that could run out of oil as well.

Solar energy does not pollute the air. If ever, the heat coming from the sun cleans the environment and maintains the earth’s eco balance. Not so with oil. Oil, its derivatives and its byproducts are great pollutants. In fact, 22,000 pounds of carbon monoxide will need to be produced first for the oil to be processed and supply a home with electrical energy for a year.

Solar energy harnessing panels are silent operators. Except maybe for the mechanical contraptions that are built into the panels so it could track the sun, from the collection of the suns rays to its photovoltaic conversion, they give neither a peep nor a squeak. It is a world of difference from the cacophony of giant drills and pumps that are used to extract oil form the ground.

Maintenance for the solar panels is very minimal. Except for the mechanical parts that are optional, almost no maintenance is needed. Once it is installed nothing much will be the cause for worry. The energy that is derived is free. With oil there is no telling what the next pump price would be and when. Oil, being a commodity, heavily depend its prices on market forces. Often with the right strategies, even market forces could be manipulated that could cause volatility in pricing.

The Disadvantages of Solar Energy

The cost. While solar energy is free, the cost of installation setbacks many household from installing it. Brand new solar energy generating systems are expensive. Although it tends to pay off overtime, initial cash out could range into several thousands of dollars depending on the quality and volume of generated power a household or an establishment would require. While solar energy technology has been around since the 1950’s it is only in recent years that its development was spurred. While costs of installation could also be subjective depending on the purchasing capacity of a customer, the benefits that could be derived out of it is enormous although mostly in unquantifiable terms.

For mass consumption, distribution lines are needed and this remains to be a big issue. Old antiquated distribution lines used to transfer electricity and other modes of fuel into the homes are clogged in many regions that to deliver solar energy power into the houses of consumers will require a different approach.

Be that as it may, the benefits from solar power far outweigh its disadvantages. It is an ideal source of energy that it may soon be the norm in power generation.

The Benefits Of Solar Energy System


Utilizing solar energy or the power coming from the sun’s rays has many benefits. Let us take a closer look on each of them.

•Solar energy saves money.

In 2006, we saw the highest jump on residential electric rate. In some areas of the country, as much as 60% increase was seen. Many experts agree that the trend will likely to continue in the years to come. This means that you have to pay larger sum of cash to sustain your monthly electric consumption. But if you produce your own power, you can prevent paying the high cost of energy – especially now when energy prices are very unstable.

On a larger scale, if American households switch to other types of alternative energy including solar energy, the nation’s spending on imported oil will greatly decrease.

•Solar energy is environment-friendly.

The issue of global warming will not go away. So if you want to do your part to save this planet, drawing your power requirement from the sun will make a great difference.

Solar energy is sustainable and renewable unlike gas, coal and oil that most utility companies use. It does not produce sulfur dioxide, nitrogen oxide, mercury or carbon dioxide as byproducts so it doesn’t pollute the air. Since it doesn’t emit greenhouse gases, it doesn’t contribute to global warming.

Using solar energy reduces demand for fossil fuel and reduces the nation’s dependence on foreign energy sources.

•Government gives incentives to those who use alternative form of energy.

Many are discouraged to install solar electric systems because of the initial cost of the project. But, some states like California offers federal tax credits as much as $2000 and up front rebate that covers 20% to 30% of the total system cost. These offers are relatively good considering the substantial increase of energy cost in recent years.

Note: Due to the increasing number of households who want to switch into alternative forms of energy, the incentive levels decline. Check with your state government the rates it offer if you are going to make a switch.

•Solar power systems are dependable and require little or no maintenance.

Photovoltaic (PV) cells that are used in solar power systems are capable of providing electricity for a very long time. Originally developed for space use, PV cells require little or no maintenance. The proof is, most satellites orbiting earth use PV cells that are in harsh environment, not maintained but are still working properly. The manufacturers of solar panels can give as much as 25-years warranty. Talk about quality and dependability.

•Solar energy helps improve the quality of life.

Saving the planet one watt at a time if done collectively will help reduce the effects of global warming. It will also reduce demand on coal, oil or gas power plants that emit harmful gases. In turn, using solar power helps clean the air and improves the quality of life of every individual.

•Solar energy can reduce demands for other non-biodegradable materials.

For utility companies to distribute power to every home, they need materials necessary in building these systems of power lines like electric cable and steel. These require energy to produce and contribute to greenhouse gases emissions. If we can cut the demand for power plant and switch into alternative energy, we can also reduce the demand for these materials and help the environment.

The Future of Generating Energy For The Home


Solar energy for residential houses is nothing new. It has just been relegated to the background in lieu of rising cost of real estate; newer more advanced building materials, design and the limitation of resources.

Since man started building homes, sunlight played a major influence in the design. In fact, even in the more advanced urban planning method of the Ancient Chinese and Greeks, the orientation of the buildings is as much as possible directed towards where it could capture the most sunlight.

The ancients might not be as intellectually sophisticated then to use catch phrases as passive solar and thermal mass but when they build, they were building in compact proportion, employing overhangs, producing insulations and building in manners that direct the airflow within the structure and producing well lit, well ventilated spaces using the relative position of the sun to the orientation of their structures.

Lately, as the conventional sources of energy became more expensive, homeowners were once again turning to the sun for energy requirements.

Since the 1950’s, harnessing the sun’s rays has been developing and today the solar cell technology has achieved very efficient levels that modern (so-called green house) designs apply the sun’s power to provide energy for the home.

While solar energy is free, the device that will convert it to run our appliances is not. To provide solar energy for the home, solar cells called photovoltaic made from semi-conducting materials, are grouped into modules. These solar panels are mounted on rooftops, yards or open spaces where it can capture the maximum amount of sunlight.

Whenever possible, the panels will be installed facing south to get the most out of the sunlight but tracking systems are also used to follow the direction of the sun. The solar panels collect the energy from the sunlight. The process basically is that when the panels are exposed to sunlight, the electrons are separated form the atoms. This movement of the electrons creates electricity.

To store power, pumps are often used – circulating water in the cells. The water goes into a storage tank where the power is stored, ready for use. Sometimes, the use of gravity is employed if it will just the same store the heated water in to the tank.

In spite of all the development in solar energy though, the use of this technology is not enough to provide power to the whole house. The best method so far can only fulfill about 80% of a households power needs. The employment of solar energy for the home will still require the use of the conventional power distribution method.

Powering the homes by solar means will still, for a while be augmented by a local power distribution agency. To many, this is already a good starting point. Homeowners that feel that the high cost of powering their houses through solar power, is justified when compared to the price that is now being paid for conventional electrification method where horrendous amounts of CO2 are being dumped into the atmosphere just to generate a pitiful amount of electricity.

However, due in part to the rising costs of energy, the technology for solar energy has been undergoing rapid phases of development. Experts are confident that within five years, powering the home through the solar method will be made widely available for those who prefer it as its sole energy source.

These are needed to produce the required energy.

Today, there are several solar power systems that are suitable to RVs. Shop around and you can find one that will suit your budget and needs. If you’re planning to bring electrical devices, you must calculate their energy needs so that you won’t use up all the solar energy. Try to limit the number of electrical devices you bring; besides, you’re going camping to explore nature so you can do away with the convenience of these devices.

Even if you’re camping without RVs, you can still make use of the solar power system. You can already find lightweight and portable units that generate solar power. There are flexible panels that can be carried to campsites and you will just spread them on the ground where there is direct sunlight. The generated power is enough to light a small bulb and a heater. Special backpacks collect sun’s energy and convert them into electricity which can be used to recharge your iPod, camera, and cellular phone.

Solar power is no longer limited to homes, offices, and other bog establishments. Now, it is already possible to carry solar power systems anywhere you go. Camping will be more fun if you bring a solar power system with you. Forget about conventional generators that consume fuel. You can get free electricity from the systems that are sold in the market. In the US, solar power is already recognized and many households are now using them.

Next time you plan to go camping, make sure that you bring a dependable solar power system. Plan your outing carefully and make sure that you pick the right date and day as well. If it’s sunny, you can produce more energy. Bring limited electric devices and bring only the essentials. Solar power is clean and renewable so you can stay out camping for as long as you like without worrying about energy consumption.

Solar Power and Global Warming


Who wouldn’t want to get a lifetime supply of free electricity? Well, that can be realized only if you install a dependable and durable solar power system. Solar power is free but only after the installation of the power system. Conventional electricity comes from the burning of fossil fuels that in turn contribute to global warming. The effects of global warming are quite evident nowadays. Many people are now interested in saving the environment to prevent the devastating effects of pollution. One way to decrease pollution and environmental concerns is through the use of solar power.

Solar power can be used in different ways especially in households. You can use it for lighting, for cooking, for heating the house, and many others. Utility bills are very expensive and you can cut it down by installing a solar power system. The system has solar panels that collect sunlight and converts the energy of the sun into electricity. You can readily use the electricity or it can be stored in the batteries.

The sun’s raw energy can’t be used to power homes and it needs to be converted first through the inverter. If you have a solar powered house, you can make use of renewable and clean electricity. Even if you can’t cut off your traditional electrical supply, you will be able to reduce the consumption thereby helping the environment. Electricity is generated by burning fossil fuels that contribute to pollution and global warming. The supply of fossil fuels is also decreasing and the world might face electricity shortage soon if they don’t conserve energy. It would be best to start using solar power now.

Through the efforts of SEPA (Solar Electric Power Association), the public is made aware of the many benefits of solar powered homes. This is the best time to make substantial efforts to save the environment. Solar power can’t possibly replace conventional energy sources today but who knows. If the technological advancements can help in the enhancement of solar power systems, perhaps in the near future the whole world can go green.

Pollution is widespread and it poses a great threat to the world. By reducing traditional electricity consumption, you can also lessen pollution. Solar power can provide clean, renewable, and free electricity. It doesn’t produce harmful emissions. You can enjoy free electricity as long as the system is working properly and as long as the sun rises.

The solar power systems are not that expensive these days. In fact, you already get a solar power kit for as low as $200. Still, the large solar panels are expensive. The federal government in the US offers incentives, loans, grants, rebates, and other financial options to help homeowners in installing a power system. Take advantage of these financial options so that you can start helping the environment.

Solar power systems can serve your home for about twenty years when properly maintained. It’s like an entire lifetime if you start now. If every home around the world patronizes solar power, global warming can be greatly reduced and Mother Nature can heal herself. Try to learn more about solar power and if you can afford to install a system at home or in the office, don’t hesitate because you’re doing the world a favor and you also get a lot of benefits.

The Cost of Solar Power Installation


Many years ago, it would have been impossible to use solar power at home because the installation cost was too expensive. However, with the advancements in technology, households and offices can now make use of solar power because the solar power system kits are more affordable. Homes that have solar power systems can expect added market value and aside from that, you can expect a significant decrease in your electric bills.

How much is the cost for installing a solar power system? If you live in the US, you can take advantage of the financial incentives offered by the government to make the installation cost more affordable.

Before you finally decide to use a solar power system for your home, you need to calculate your electrical needs. Determine the kWh that your home consumes in a month and in a year. You can find such info on the monthly utility bill. Study the bills so that you will now which months have the greatest consumption and the months with the least consumption.

New homeowners can compute their electricity consumption by checking your electrical appliances. Just estimate the load based on your appliances, lights, and other things that consume electricity.

Electrically bills are showing a continuous upward trend and so many people are now complaining about their monthly bills. A very good answer is solar power. Where do you live? The place where the home or establishment is situated is a primary consideration. In the US, you can install the solar power system in any of the states. If you can find solar contractors locally, you can seek their help to determine the appropriate size of the system.

1-5 kW of solar power system is already enough to meet your home’s electricity needs. You don’t need to cut off your existing power supply in order to utilize solar power. You can simply use the photovoltaic systems as a supplement. This step alone can already reduce your monthly bills. Do you have enough space for the photovoltaic system? For every square foot, you can already yield 10 watts; you can start your computation from there.

Here’s how you can compute the total cost: the retail price of the system plus the cost of building permits, less federal tax credit of $2,000 and the local or state rebates/tax credit, less other incentives equals to your net investment. You can shop around for the best and most suitable solar power system in the market. If you live in California, it will be easier to find local sellers of solar power systems because many homes in the city are already solar powered. For those living in other places, it would be easier to shop online. There are lots of online stores that offer photovoltaic systems but try to stick with the reputable and established manufacturers that offer 10-15 years of warranty.

Instead of paying for expensive monthly utility bills, why not invest in solar power systems? The total cost will depend on the size of the system, your location, and other related factors. Inquire at a local agency about the incentives offered by your state so that you can also save money. It’s a wise decision to invest in photovoltaic systems because you’ll benefit greatly in the succeeding years. Shop around now and determine your available options.

Wind and Solar Power


Going back to the basics is the trend these days. Many people are now aware of the many problems faced by the world which includes pollution, depletion of natural resources, increasing population, and many others. With so many problems to deal with, people don’t know where to start. You don’t have to be a hero to help save the world and address its many problems. Why not contribute in your own little way by using solar power and wind power?

Sunlight and air can be converted into energy though solar and wind power. A solar power system collects sunlight which can directly heat homes or it can convert the heat into usable electricity and store them in batteries. Wind energy can also create usable electricity or the mechanical energy can also be used directly.

There are advantages of using solar and wind power. After the initial expenses for the installation of the systems, you can enjoy free energy for many years. Most of the power systems last for approximately twenty years and requires little maintenance. As long as the systems are cleaned once in a while, it will surely work efficiently. Solar and wind power are both pollution free and does not emit greenhouse gases that contribute to global warming. Solar panels and wind turbines require little maintenance. Some people are concerned about wasting land to install wind turbines but you can still use the land for planting crops and for grazing animals.

According to researchers, the efficiency of these systems relies on the environmental elements. Germany and Japan are leading the way to the improvement of solar energy despite the fact that these countries get very little sunshine in a year. On the other hand, wind turbines are too noisy and unsightly. Turbine blades cause the noise and the huge structure can ruin any landscape.

To produce significant energy, you will need a lot of solar panels or reflectors and turbines. Size is a vital consideration for producing the needed energy. Have you ever been into remote areas? You can use solar power and wind power to generate the needed electricity. During daytime, you can depend on solar power to provide your electric needs and at night, you can use the wind turbines.

Solar power systems and wind turbines are not very difficult to install. In fact, there are now DIY kits that can be readily purchased locally and in online stores. You will just follow the guided instructions and get the necessary materials. The systems can be installed over the weekend. For those who live in the city, you can take advantage of the tax incentives, financial options, rebates, loans, and grants offered by the government. That way, you can have the system installed at a very affordable cost. In the case of wind turbines, you will need a lot of space. There are now turbines that produce less or no noise at all which are excellent for homes with close neighbors.

The decision to use solar power or wind power is a matter of personal choice that is usually affected by certain factors like money (investment), space, and energy requirements. Just imagine making a one-time investment and after that you can already enjoy unlimited and free supply of electricity. Regular inspection can ensure that the systems are working efficiently.

Solar Energy – To Supply the Needed Power


The world is currently suffering from energy and fuel crisis. Fossil fuels are incessantly depleting and so energy bills are soaring higher and higher. Many homeowners and establishments are now complaining about their huge expenses. But did you know that there is an answer to the crisis and it has long been available to man. However, because of its inefficiency, it is not recognized as a viable solution. Solar energy is free but the cost of generating it is a bit expensive. With the vast improvements in technology, there are now more affordable options for those who want to use solar energy to supply power in their homes and offices.

Today, you can find a lot of manufacturers that market solar power kits. How effective are these power kits anyway? Many households are now utilizing the kits because they are efficient and convenient in generating the needed power from sunlight.

Battery chargers that are powered by solar energy are now widely available. Now, you don’t need to rely fully on conventional electricity to power electrical devices. If you install the right size solar panel, you may be able to decrease your dependence on conventional energy sources. The energy from the sun is free and you will simply need to invest on the kit for a good power system.

People usually think that without sunlight, power can’t be generated. The power kits are not only designed to capture the sun’s energy but also to store the energy as well. During sunny weather, energy from the sun is converted into electricity and those that are not consumed will be stored. The stored energy can now be used at night or during unpleasant weather.

With portable chargers, you won’t be able to get enough power. You can only use them for recharging small electric devices and batter packs. Cellular phones can be charged using the portable solar power chargers. The power is easily drained out and so it’s not a very efficient source of energy. Despite the shortcomings of these devices, it would help if you still have them around. Who knows… a few years from now, researchers and scientists may be able to make a major breakthrough in solar power.

Since the power kits are affordable, a lot of people are now using them. A solar panel usually has one charger where you will plug the equipment. The solar chargers are very useful and you can carry them even in your hiking trips. Just place them on your car’s dashboard where sunlight is accessible.

The portable chargers or solar panels can be mounted in the rooftop to get a lot of sunlight. The large panels are still expensive and not many people can afford to buy one. However, governments can subsidize the investment to set up the power system. If you live in a place where the government offers subsidies, grants, and loans for the use of solar power, you’re quite lucky. Take advantage of it so that you can now use free energy. Tax incentives are even offered in some places to encourage residents to go for solar power.

If you’re still not sure about the efficiency of solar power, you can start by using a power kit. You can get the kit for as low as $200 to $300. Try it now and expand the system later on.

Solar Power Info


Perhaps everyone knows what solar power is. For many years, solar power has been used but because of the inefficiency of the gadgets being used, it can’t be utilized to its fullest potential. Researchers and scientists are continuously making improvements so that even ordinary people can now use solar power for their homes and for businesses. If you’re looking for solar power info, you’ve come to the right place.

To understand solar power better, you must know some of its components. Firstly, take a look at photoelectric or photovoltaic cells. These cells are responsible for converting the sun’s rays into electricity. The solar panel contains photovoltaic cells that produce the needed energy. With a square meter of the solar panel, you can already generate enough electricity to light a 100w light bulb.

Solar power can heat water in your homes as well. You will simply install glass panels on the roof and that’s heat. A solar power thermal system can benefit you a lot by decreasing your monthly electric bills.

Are you familiar with solar furnaces? It makes use of mirrors to capture sunlight and provides high temperatures.

When using solar power, you need to know its good points and bad points. Solar energy can help in reducing pollution and waste. You will no longer depend on fuels for energy and the best feature of all is that it is totally free (that is, once you’ve installed a solar power system). Small villages that are located far from conventional energy sources can surely benefit from solar power. In sunny countries, solar power can be used to the fullest but since resources are limited, very few are able to enjoy its benefits.

Solar power is renewable and it can be used for different purposes. Examples are solar calculators, garden lights and fountains, and battery chargers. As long as the sun shines in the morning, you will get a renewable source of energy.

The problem faced by researchers today is that many places don’t get enough sunlight all throughout the year. The solar power devices can work more effectively in places where the sun is brightly shining. Some places don’t enjoy too much sunlight and this is where solar power becomes unreliable. A very good example is United Kingdom. In the UK, solar power can only be used in low=powered or small devices.

In the US particularly in California, solar power is used by many homes and establishments. The Los Angeles area gets a lot of sunshine and because of this it’s much easier to generate solar energy. California’s goal is to increase the use of solar power consumption to 10% in the coming years. The use of solar power is being enhanced year after year with the advancements in technology. Scientists and researchers are discovering new ways to use solar power to the fullest. Several years ago, using solar power was rather expensive but today, you can already enjoy its benefits for as low as $200. The solar power systems kits are very affordable and you can use them to light your garden and other outdoor lights. If you can expand the system, you will soon be able to use it indoors.

You will know what solar power is by knowing its main uses. So whenever you see the sun, you will know that energy can be generated from it through the use of special devices and equipments.
