The sun may be millions of miles away, but we can utilize its energy to perform countless functions. Unlike fossil fuels, solar power is a clean energy source that doesn’t pollute our planet. Solar technology has made giant leaps forward in recent years and average families can now use solar energy as a part of their everyday lives. In this article, we’ll show you why solar power products are the wave of the future.

Some classifications of solar technology are active, passive, direct and indirect. Active solar systems use electrical and mechanical components such as tracking mechanisms, pumps and fans to process sunlight into usable outputs such as heating, lighting or electricity. Passive solar systems use non-mechanical techniques of controlling, converting and distributing sunlight into usable outputs. Direct solar generally refers to technologies or effects that involve a single conversion of sunlight which results in a usable form of energy. Indirect solar generally refers to technologies or effects that involves multiple transformations of sunlight which result in a usable form of energy.

Solar technology has impacted a number of common practical products. Residential solar products have proven themselves to be quite reliable. A thermal mass is a body that absorbs and holds heat. In the context of solar energy, it is a mass designed to store heat during sunny periods and release heat when sunlight levels are reduced or unavailable. A properly sized thermal mass will smooth out temperature swings and help keep rooms at a comfortable temperature throughout the day and night. Many homes use a solar water heater instead of oil or gas to heat water. The solar powered car is expected to be the next great advance in solar technology.

Solar technology is more common in the every day world than you may think. Calculators powered by cells instead of batteries are using solar power. The technology used to transfer sunlight into usable isn’t cheap, but the value of a clean planet makes it worthwhile. Soon, everyone will use renewable energy sources to power their homes and businesses. Researchers believe that by the year 2030, most people will be using alternative energy sources to supply the power they need to heat their houses, drive their car or just watch television.

Solar technology is one of the means by which we can save our planet and ensure that there are sufficient resources for generations to come. Solar power can be used in tandem with wind energy to provide more than enough electricity to power entire cities. People who are concerned about the environment are lauding the benefits of this technology to governments worldwide. With investment from our leaders, solar power can change the way we bring power to the people.

If you’re drowning in the cost of your utility bills, then investing in a solar water heater may be the lifejacket that you’re looking for. These hot water systems can save you a bundle on heating water for your home because it uses sun energy as fuel. Unlike fossil fuels, sunshine is free, clean and there is an infinite supply. In this article, we’ll explain how these systems work and how it can save you money.

Sun powered water heating systems include storage tanks and solar collectors. There are two types of these heating systems: active, which have circulating pumps and controls, and passive heating systems, which don’t. Passive heating systems are typically less expensive than active systems, but they’re usually not as efficient. However, passive systems can be more reliable and may last longer. For active systems, discuss the maintenance requirements with your system provider and consult the system’s owner’s manual. Most water heaters that run on sun power, require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.

Solar water heating systems almost always require a backup system for cloudy days and times of increased demand. Conventional storage water heaters usually provide backup and may already be part of the solar heating package. A backup system may also be part of the solar collector, such as rooftop tanks with thermosyphon systems. Since an integral-collector storage system already stores hot water in addition to collecting solar heat, it may be packaged with a backup water heater.

Before you purchase and install a solar powered water heating system, you should consider the economics of solar energy systems, evaluate your site’s solar resource, determine the correct system size and energy efficiency and check into your local codes and regulations. The proper installation depends on your solar resources, climate, local building code requirements and safety issues. It’s best to have a qualified, solar thermal systems contractor install your system. Regular maintenance on simple systems can be as infrequent as every 3–5 years, preferably by a solar contractor. Systems with electrical components usually require a replacement part after 10 years.

Although solar water systems do have minor problems, the technology is quickly catching up. These systems are a smart investment for consumers because they pay for themselves in a relatively short period of time by reducing your utility bills. As a bonus, many governments and manufacturers offer rebates to people purchasing environmentally friendly household products. Buying a solar energy system is a win-win situation. You can save money on your utility bills, all the while being environmentally responsible.

Most regions depend on coal plants, nuclear plants or oil and natural gas plants for energy. However, the development of solar thermal energy is paving the way for cleaner energy from a renewable power source. In this article, we’ll explain why the solar power plant could change the way the world uses its resources.

Solar thermal energy is the heat that can be gathered from solar power without the use of photoelectric cells. It is a form of energy that can be transferred into water and stored in insulated containers and kept heated constantly by the sun, while retaining energy overnight. They are also used to heat water and homes. Some thermal energy is used to superheat water in massive solar power plants that use steam based turbines to generate electric power. This is very environmentally friendly because no emissions are produced.

The collection of solar thermal energy is usually done through a panel or a series of panels which pump water. These panels are commonly seen in a home’s hot water system and can cut consumption of energy used for heating water by more than half. Various collectors, such as solar hot water panels, are commonly used to generate solar hot water for domestic and light industrial purposes. Solar thermal energy is used in architecture and building design to control heating and ventilation in both active solar and passive solar designs.

There are a variety of cost efficient solar thermal systems available to homeowners, so you have to choose which best meets your needs. A closed loop solar thermal system supplements heat to your hot water tank. This system will cost about $4,600 US to install, but prices are steadily decreasing. Another popular closed loop system is called a drainback. The solar pool heater, which is an open loop system, is a very practical product. It’s called this because water circulates back into the pool since it’s an open system. A solar blanket, while not technically a solar thermal system, is an economical way to retain and increase the heat of your pool. Many governments are offering rebates to consumers who buy environmentally friendly products.

Foremost on the minds of consumers in the desire for cost efficient and environmentally friendly sources of energy. Solar thermal plants are providing an alternative to coal, oil and nuclear energy. Sun power is a free and renewable fuel for these systems. While the technology is costly right now, the expense is becoming more moderate as the technology advances and becomes mass produced. This is just one way to conserve the world’s energy resources.

Solar electric is the term used to describe something which uses sunlight to produce electricity. Solar power is one of the cleanest forms of renewable energy available and it can be used in several forms. In this article, we’ll shine a light on how the solar powered revolution is changing the way homes and business are run.

Solar electric systems are becoming more compact than when they were first created. Solar photovoltaic tiles and other forms of solar energy work by converting some of the energy in sunlight into a clean form of electricity. The PV cells consist of a positive and a negative slice of silicon placed under a thin piece of glass. As the protons of the sunlight beat down onto the PV cell, they knock the neutrons off the silicon. The negatively charged free neutrons are attracted to the silicon, but are trapped by the magnetic field that is formed from the opposing fields. Small wires on the silicon catch these neutrons and when connected in a circuit, an electric current is formed. The nature of the PV cell means there is little or no maintenance required and there are no moving parts. This means that a typical PV cell can last up to 40 years with no maintenance required besides an annual cleaning.

There are several ways to use solar electric power around the house. Solar retrofits are solar energy applications for an existing home. Solar electric power can be used to provide domestic hot water, swimming pool heating and electricity for lights and appliances. Even your central heating can be solar electric if you have adequate roof space for solar panels and an adequate amount of sun. An efficiently solar powered home will be able to reasonably create between 75% and 100% of their own power because of the grid tie system. This means your utility bills will be significantly reduced.

As technology develops, so does the number of solar electric products. Clocks, radios, torches, battery chargers and calculators are just some of the small solar energy appliances available on the market. The solar powered appliance market is steadily growing as the demand for environmentally friendly products increases. The impact of the solar industry can be huge, both economically and environmentally. For instance, by reducing the need for dry cell batteries, we reduce the lead that leaches into the ground from disposed batteries. That prevents our soil and drinking water from becoming contaminated.

Solar energy systems are one of the cleanest and most efficient ways to create power. By increasing the use of solar cells, we avoid depleting the planet’s resources. However, the technology won’t make a difference unless people choose to use it. By mass producing solar electric products, corporations can make these items more affordable to the consumer. Who wouldn’t want to save the planet inexpensively?

If you and your family are more concerned about ‘living green’ this year, you’ll definitely want to learn more about solar energy. There are a few solar energy sources that your family can choose from, and you’ll save lots of money every year on electricity bills–plus you’ll be doing your part to care for the environment.

Solar energy refers to the light and heat from the sun that is ‘trapped’ by humans using a number of different technologies. Other sources of energy, such as wind power and wave power, along with hydroelectricity, are often used for homes and businesses that are ‘going green’, so that all of the building’s systems will be running efficiently with sources from nature. This is partially due to the fact that only a small amount of solar supply is actually used by humans, since the sun is millions of miles away, and some parts of the earth do not receive sunny weather often. The practice of building in a way that will capture natural sunlight has been a practice of architects for centuries, and dates back to ancient Greek and Chinese cultures.

One of the solar energy sources that your home can benefit from is a solar panel. This is installed in the home at a place where the sun would naturally shine, so that electricity will not have to be used in the area. The natural light is also ideal for plants that you may have growing in the home, and reduces the amount of money that you will spend on manufactured electricity every year. Other solar energy sources include panels, pumps, and fans. These instruments promote solar technology by using passive or active methods of capturing sunlight for energy. Active solar energy sources also include photovoltaic panels, which are more common for factories and larger businesses. Passive solar energy technologies involve the selection of materials with positive thermal characteristics. These methods create space that will naturally circulate air, and there are a number of construction companies that work to position a building toward the sun before it is built.

If you want to find out more about solar supply or solar energy sources, you should talk to a representative from your city council. This will give you the details you need about urban planning in your city or state, and will let you know how much money is being spent on electrical energy and new construction. You may also want to get in touch with housing developers and builders in your area to learn about how much money you’ll be saving by building a solar-powered business; corporations like Pulte and John Weiland Homes may be able to help.

We use electricity for many things in our lives, and often do so without thinking twice about it. We turn on the switch for lights in our home and to turn on electronic devices all the time. Yet we need to do our best to save as much power as we can.

The types of light bulbs that you are using can be a problem for the environment. There are many places that sell those that are energy efficient though. You can get them in any size you need for all the rooms in your home. They aren’t very expensive and what you do spend on them you will save with a lower electricity bill each month.

It is very simple to cut back on the amount of lighting you use at all though. During the day open curtains and allow the natural sunlight to shine through. Then you will only need to turn on the lights at night when the sun goes down or on cloudy days.

The use of sky lights has become very popular for businesses and even in newer homes. This allows the sun to be shining through the ceiling and so less electricity has to be used. Some of the larger retail stores such as Wal-Mart use this as much as possible.

Look up as you walk through one of their stores. You will notice during the day they don’t have very many lights on at all. Sometimes a cloud will roll in front of the sun and you will notice it immediately gets darker in the store than before. They are saving a huge amount of money on electricity and they are also helping the environment.

There are many ways in which you can generate electricity too that comes from alternative power. You can place solar panels on your roof which will collect electricity. That is the source your home will use for all of its needs when you turn the power on to something.

Should you run out of the solar power that has been collected it will immediately kick over to the regular electricity without any interruption to you at all. There is also the use of wind and water power in some areas. Take a look at these alternative methods and see what you can do with them for your own home.

A big waster of electricity that pollutes the environment is leaving light bulbs burning on your porch when you are away from home. You don’t have to go without lighting when you return but you don’t need to do it that way anymore. There are some great alternatives to consider.

You can place decorative solar lights along your driveway. Some of them are very short while others are tall lantern style. It is completely up to you which look you would like to have for the landscaping of your home. Since you don’t need to plug them in to an outlet you can place them anywhere you would like to out there.

These lights collect power from the sun in the day time and as soon as it gets dark they will illuminate your hard. When they run out of solar power they will turn off. Should they have enough to last all night then they will turn off when they sun comes up and start collecting energy to use all over again.

Another alternative is to install a motion light. This is a type that doesn’t have to be left on when you leave home. When you pull into your driveway it will turn on based on the movement it has detected. It will remain on for a short period of time which allows you to get safely into your home with the light you need.

The use of windmills in many areas to create energy is also being looked at. Sometimes water known as hydropower is available too. However, the light bulbs you use can help you get the most out of these benefits.

If from start to finish everything in your electricity gathering and using process is eco-friendly you won’t feel bad about consuming it to operate lights and the electronics that you use in your home and business.

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

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.

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.

Looking at the current price of fossil fuel-based electricity, it is quite impractical to convert into solar energy system. However, with the growing concern on the state of the earth, there is really a need to find other means of energy aside from what power plants are using right now. Where do you place yourself?

Whether you are an advocate of clean energy or simply care about where your finances go, looking at the pros and cons of residential solar energy system will help you decide on whether to convert or not.

Pros

Solar energy is free. Did you know that the earth absorbs 174 pettawatts of solar radiation? This means that we have more than enough source of free energy to power every house in the world. Unfortunately, most of our energy is still drawn from oil, gas and coal. But in recent years, there is a steady increase of demand for alternative and renewable energy like solar power. It is estimated that the demand for alternative sources of energy will increase by 53% between 1999 and 2020.

Solar energy is clean, renewable and sustainable. Because the energy created from the sun’s rays does not produce byproducts like those from fossil fuel power plants (sulfur dioxide, nitrogen oxide, mercury or carbon dioxide), it does not contribute to pollution. Accordingly, the increase in the use of solar energy and other alternative forms of energy will decrease the demand for greenhouse gases-producing power plants.

The price of photovoltaic cells is steadily decreasing. The demand for solar panels has risen by 57% in the United States in 2007 and is steadily increasing on a monthly basis. The increase in demand results to the improvement of solar technology as a whole. The prices of photovoltaic cells have declined on the average of 4% every year over the past 15 years.

Solar panels can be installed on most rooftops, eliminating the problem of finding a suitable place for installation. Solar panels require little or no maintenance. The original photovoltaic cells technology is used for most satellites orbiting our earth today which are not maintained at all. Many solar panel manufacturers give 25 to 40 years warranty on their products.

Because most areas of the country receive a substantial amount of sunlight throughout the year, solar panels can be installed anywhere.

Many states in the country give tax credits and rebates to households who want to install solar energy system. Check with your state government the cost of these incentives.

Cons

While the prices of PV cells are in constant decline, the cost of installation is substantially high compared to the current electric cost. But the good thing is, after your initial cash out, you don’t have to pay every month on electric bills for the rest of your life.

On areas cities and areas with heavy pollution problem, solar energy may not work as fine. Weather can also affect the efficiency of solar energy. If it is raining, overcast weather or if there is a hurricane, the solar panels’ efficiency is decreased.

You are only producing energy during day time.

These are general pros and cons you might encounter when considering the conversion to solar energy system. It would be best if your decision is based on location, cost, budget, rebates, tax credits and practicality.

Previous predictions that it will still happen in a decade may no longer be true. The anger generated by the recent prices in oil and its vulnerability to market forces and other events may have already been enough to polarized people, governments and scientific communities into seriously considering a reliable alternative energy source.

You can not get a source more reliable than the sun. Even today homes that uses its power does not only benefit from the silent, energy generating, inexhaustible power of the sun, it also spikes up the prices of their homes. Those that have solar powered homes are even reimbursed for the surplus power that they supply to the power grid.

Presently, heliostats, photovoltaic cells and plate collectors are being used to collect the energy by focusing these panels towards the sun or constructing and installing the panel’s on spots where the sun shines most. Development in technology as we all know often has a snowball effect. It never stops rediscovering and reinventing that the speed of development could often be surprisingly fast.

Today, a polymer foil, thin as a sheet of paper and lighter by 200 times when compared to the regular glass collecting plates, are being developed. Chances are, these new inventions and discoveries could very well have a great potential for mass production. Previously, the glass-based materials used for heat collection need expensive substrates and require additional support for mounting due to its weight. The polymer foil, being very light could now be attached even to the walls of a structure.

So confident are scientists in the development of this technology that while the polymer foil is being developed, a plastic solar cell, based on nano technology is gaining breakthroughs. This plastic material can collect the power of the sun even on a cloudy day through harnessing the infrared rays is believed to be five times more efficient than the current technology.

While plastic materials for harnessing the power of the sun are not new, it is only recently that this plastic composite could harvest the infrared portion. Previously, only the visible rays are generated, the infrared part, which is half of the power of the sun, is invisible.

Currently, the best plastic solar cells could only harness 6% of the suns energy, with further study and development, this new plastic solar cells are expected to harness 30% of the suns solar power.

Scientists and researchers alike agree that ultimately, solar farms will be harnessing all our energy requirements and costs of power will drop. Today the price of solar powered energy is about 3 to 4 times per kilowatt hour compared with conventional electricity. That could change dramatically though the development of the existing technology and recent discoveries.

The roller pressed flexible plastic materials and the polymer foil are only two of the best hopes in arriving at a cleaner, greener and safer environment that could ultimately free the planet from its dependency on the depleting supply of oil.

First, solar panels are installed over a flat surface like the roof of your home. Once activated, it absorbs the sun’s rays since the panels are made of semi-conducting materials such as silicone.

Electrons are then knocked off loose from their atoms so it can produce electricity. This process by which light is converted into electricity is better known as the photovoltaic effect.

From there, you now have direct current electricity and when this enters an inverter, it is converted into 120 volt AC which is the electricity needed to power the home.  Of course this is connected to the utility panel in the house so the lights and the appliances will work when these are switched on.

If you are not using that much electricity from the solar energy generated, it is stored in a battery so will be able to supply the house with power during a power outage or at night. Should the battery be full, the excess electricity is then exported to the utility grid if your system happens to be connected to it. When your solar energy runs out, utility supplied electricity kicks in.

The flow of electricity of solar energy is measured using a utility meter which spins backward and forward. It will go backward when you are producing more energy than you need and forward when you need additional power from the utility company. These two are only offset when you pay for the additional energy from the utility company. Any surplus is sod back to what is known as net metering.

A smaller version of this is used to power a water heater inside the home. Using the same principles, homeowners get to convert sunlight into heat to get warm water.

As you can see, transforming sunlight into solar energy is very easy. But why do countries like Germany and Japan use it more often than the US? The answer is because it is much cheaper for them to use this form of alternative energy compared to oil.

Also, although the US initiated this during the 1973 oil crisis, it is not as popular as it was back then because the government neither increased the budget in research for alternative forms of energy nor gave incentives so people will be encourage into doing that again.

Most state regulations also prohibit individuals from installing their own devices even if this is used to give you warm water. Chances are, you won’t even find anyone to do it so you will probably have to do it yourself. Just remember that if there is a problem with the plumbing, your insurance will not cover it. Should the state allow you to install such a system, you will not be entitled to the rebate.

Using solar cells is just one way to make the most out of solar energy. Your other option is passive solar energy which helps avoid heat loss so those inside will not feel too cold or too hot throughout the day. This is used by a lot of homeowners living in the southwest since they do not need that much insulation compared to homeowners who live in other parts of the US.
