Satellites are orbiting the Earth in extremely cold temperatures in space, yet we know that solar panels are very effective in powering them.  Obviously if solar panels will work in the coldness of space, they certainly will provide energy in any of Earth’s coldest climates as temperature is not a factor in their use.

We can share knowledge about solar power and methods of implementing clean solar energy to our own homes by making the learning process fun and interesting. Of course the ultimate goal would be to see real tangible results in the form of solar power being generated, adapted and used in your home. The best way to accomplish this learning experience is by assembling your own solar power kit with your children!

Solar power kits can be constructed with detailed solar power plans which guide you from start to finish on your project. An informative guide will provide you with sources of low cost parts and easy to follow diagrams that will help you to construct your very own solar panel system.

Are solar panels easy to make? At first thought, it may seem complicated but in reality they are quite easy to put together. By assembling your own solar panel system, you will pay a tiny fraction of retail prices by utilizing the source of low cost parts.

A great side benefit of learning how to assemble your own solar power system is that you can make additional solar power kits for your friends and family. By adding a reasonable profit margin, you will be able to create extra income for your family by selling ready made solar power kits to others.

Through knowledge and practical implementation of solar power, we can build a cleaner future for the next generation to enjoy.

Solar Power Gadgets - Using Energy for Solar Chargers

Find out more information on Solar Power Gadgets compared to normal battery power gadgets.

The overwhelming majority of electronic equipment/gadgets today are dependent on a power supply in order for the gadget to properly function, in most cases the gadget cannot function at all without such a power supply. Due to a number of considerations such as issues concerning cost saving strategies for manufacturers and consumers alike, fears over the environment and the impact currently existing power supply methods are having on the climate have prompted the latest innovative breakthrough: solar power.

Solar power, (the harnessing and utilising of the rays provided for by the sun) is ecologically friendly, has huge cost saving implications (with no need to continually replace batteries and a totally "free" as well as 100% renewable power source) and is steadily beginning to become more and more prevalent in different types of consumer products.

One especially exciting application of this technology is in the pursuit of solar powered cars. The SP car has a series of panels on the outside of the car, allowing it to act like a plant by absorbing the sun’s rays and converting it into electrical energy which the car will run on as fuel.

Sadly, due to a number of limitations, solar powered cars are currently not available on the market for the average consumer, the current models of solar powered cars whilst ambitious in their goals, are dogged by a number of limitations that make them inappropriate and ill-suited for the demands of modern life.

In order to best achieve optimal performance, solar cars tend to be extremely lightweight, typically produced using specialised materials such as aluminium, if the solar powered cars were to be used and adapted for more mainstream consumer use, this careful balance would have to be majorly reviewed and altered which with current technology seems a rather unlikely event. All is not lost however, even though a full-scale solar powered car maybe beyond our means and current capabilities, the current technology presents opportunities for some technological advancement.

There is a great deal of excitement about the strengthening of the electric battery currently used in solar powered cars, and researchers are hoping to reach a happy medium of the average car, and this new electrical battery design. Currently, solar power technology maybe implemented in golf buggies, because they tend to be small, lightweight vehicles with low speeds and which spend most of their life out in the sun anyway, it seems a very attractive option.

Therefore, they enjoy a particularly strong presence in industry and engineering, and to date, all solar cars ever produced have been created to participate in government-sponsored races for totally solar powered and operated cars.

The very heart of the solar powered car is the electrical battery system, as it regulates and governs the power that enters and leaves the vehicle, in effect, the electrical battery system is the solar car equivalent of the petrol tank for a conventional car. Typically, Nickel-Cadmium, lead-acid and lithium ion batteries are all currently used in solar powered cars.

Ausra Solar Heat and Power Information

It’s difficult to stand out in the competitive solar energy market, but Ausra, an Australian-American company, seems to be successful at setting itself apart from the competition.

The California-based Ausra got its name from an ancient Indo-European goddess of the dawn. It is a solar thermal technology company that produces electricity from sunlight with fewer issues compared to the traditional methods, and could even lower the expenses of generating utility-scale power.

In order to generate electricity, solar thermal power plants harness heat from the sun. Ausra utilizes quite inexpensive 40-foot-long flat plate mirrors known as Fresnel reflectors to focus the sun’s rays directly on the water pipes and thus boiling the water to run the steam turbines, which will then generate electricity.

Generally, most solar power plants use structures with curved mirrors to focus sunlight onto tubes of oil. The heat from the oil is used to make steam, and then drive the turbine, which generates electricity.

Ausra Solar Heat and Power uses a system that can reduce the cost of electricity that is powered by solar energy, and that can compete with traditionally generated electricity. Its Fresnel lens reflectors are different from the curved mirrors of the conventional trough design, as the Fresnel lens appears to be flat.

Rather than first heating the oil to generate heat, Ausra heats water directly in order to generate steam. However, the system can be less effective at converting solar energy into electricity compared to the trough systems.

Ausra was founded by David Mills in 2002 as Solar Heat and Power in Australia. Mills started the technology at Sydney University in the early 1990’s with Graham Morrison, who helped him develop it from 1995 until the year 2001.

In 2004, Ausra Solar Heat and Power then built a one-megawatt pilot project for the Macquarie Generation in New South Wales. The company then moved to the United States in February and is expecting to finish a second 38-megawatt capacity power plant in 2009. Another of the company’s projects involved a 180-megawatt power plant in the United States and a 6.5-megawatt power plant in Portugal, which has begun its construction.

Solar Power How It Works to Power Your Home

Are you puzzled by the various terms solar power installers use when describing a residential solar power system? Does it make you head spin? Find out how solar power works. Learn the basic terminology so that you can make an informed choice on if residential solar power is the right renewable energy source for your home.

With the rising cost of electricity purchased from the local electric company, people are starting to explore other ways of powering their home. Solar power in the form of electricity generation is also known as solar photovoltaic energy converts sun light into electricity. The most commonly associated component of a solar power system are the photovoltaic panels or solar panels that you see mounted on roofs.

Why are solar panels mounted on the roof?

In order to get the maximum electrical output from photovoltaic panels they need to be oriented to solar south in the northern hemisphere and solar north in the southern hemisphere. The solar panels need to be facing toward the equator to get maximum sun exposure.

Most solar photovoltaic panels are set at home latitude plus fifteen degrees or home latitude minus fifteen degrees. Depending on if you want a summer or winter bias to the angle of the solar panels. In higher latitudinal areas it makes more sense to have the photovoltaic panels set on a winter bias, so that during the winter the solar panels still get enough sun light to produce electricity.

How does a photovoltaic cell produce electricity?

A solar panel consists of a collection of photovoltaic cells. Each photovoltaic cell is made up of silicon wafer. During the manufacturing process, an impurity is added to the silicon to make conduct electricity. The sun’s photons strike the solar cell and cause an electron to break free. This action creates a small electrical charge. The metal grid that you see on the surface of the photovoltaic cell captures the electrical charge and channels it to the solar panel’s terminals.

Solar panels produce a form of electricity known as DC or direct current. The voltage produced is considered low voltage in the range of 6 to 24 volts. Photovoltaic panels have a nominal output voltage of 12 volts and an effective operating voltage of 17 or more volts.

A solar panel’s electrical output is affected by several factors. They are angle of the photovoltaic panels to the sun, time of day, time of the year and weather conditions. Solar photovoltaic panels produce the most electricity during the middle of the day when the sun is directly overhead compared to the early morning and late evening when the sun light is striking the solar panel at a shallow angle relative to the panel’s face. Think about it, in the summer in the middle of the day doesn’t the sun feel hot? However, in the evening the sun does not feel as hot. This is because in the evening the sun’s light has to pass through more of the atmosphere which is diffusing the light and energy.

Residential solar power system

A residential solar power system consists of four components are: photovoltaic panels, charging controller, battery pack and an inverter. The photovoltaic panels convert sun light into electricity. The electricity is sent to the charging controller who keeps the battery pack fully charged, but not over charged. The battery pack sends the electricity to the inverter who converts the DC voltage to household AC at 120 volts and 60 hertz.

Photovoltaic panel

Solar panels are rated by their wattage. The higher the solar panel’s wattage the more expensive it will be. Since there are so many different factors that affect the amount of electricity produced by a solar panel many manufactures provide the wattage in terms of peak sun hours. Peak sun hours are the hours when the sun is directly overhead and shining directly on the photovoltaic panel.

Charging controller

Charging controller or charge regulator controls the charging of the battery pack. It continually monitors the battery pack’s charge state. If the batteries are low, it will feed electricity from the solar panels to the batteries. It also prevents over charging of the battery pack.

When it is night time or a cloudy day the charging controller prevents the electricity from flowing from the battery pack to the solar panels. If it did not do this, at night the solar power system would run in reverse and drain the batteries.

Don’t allow someone to convince you that a charging controller is not really required. Directly connecting the photovoltaic panels to the battery pack can permanently damage the batteries and possibly cause them to explode.

Battery pack

The battery pack’s purpose is to store electricity generated by the solar panels during the day. The battery pack is also connected to an inverter which in turn is connected to the house’s electrical network. When it cloudy or at night, the electricity stored in the batteries is used to meet the power needs of your home.

The battery pack typically consists of lead acid batteries. Lead acid batteries are relatively inexpensive and readily available. There are many different types, sizes and capacities of batteries available. The most popular types of lead acid batteries are gel cell and AGM deep cycle batteries. This is because they are maintenance free and last a lot longer compared to wet cell lead acid batteries.

The most important thing to remember about the batteries is that they need to be deep cycle. Deep cycle batteries are designed to be discharged to nearly empty and slowly recharged. They can handle this cycle thousands of times before the battery is worn out.

Some residential solar power system owners think that they can replace the deep cycle batteries with automotive batteries. The automotive battery cost significantly less than the deep cycle battery. The problem is that automotive batteries are designed to discharge quickly and then immediately be recharged. The act of starting your car drains a significant amount of power from the battery. Once the engine starts the alternator begins to recharge the battery.

Inverter

An inverter converts the DC electricity stored in the battery pack into household 120V AC. Almost everything in your home is powered by 120V electricity. A few things are powered by 240V such as the air conditioner, electric dryer, electric stove and oven.

There are two main types of inverters sine wave and modified sine wave. The power company provides electricity as a sine wave. The electricity’s charge value goes smoothly from positive 120V to 0V to negative 120V and then back up to 0V and finally up to positive 120V. Then the cycle begins all over again. The time it takes to go through the entire cycle is one second.

Modified sine wave is also known as a square wave. Here the electricity’s charge value goes from positive 120V to negative -120 volts in effectively zero seconds. The advantage of the square wave inverter is that it is more energy efficient than the sine wave inverter.

Energy efficiency is an important factor to keep in mind in a residential solar power system. The more efficient the system will result in more of the electricity produced actually being used by you instead of being lost in the system.

Most household devices will function on a modified sine wave power. Light bulbs and motors will work, just not quite as efficiently as they would on sine wave electricity. Compact fluorescent light bulbs will give off a hum and motors will run warmer that normal.

However, there are some electronic devices that will not work on square wave electricity. It will be necessary to check with the manufacture to determine if the device will work on square wave electricity or not before having your residential solar power system designed and installed.

Another function of the inverter is to stop draining the batteries when the batteries have been discharged to a certain level. Most of the time the inverter will stop draining the battery pack when the battery pack has about 40% of its capacity remaining. Completely discharging a lead acid battery will shorten its lifespan significantly.

Whew, that was a lot of material about photovoltaic panels, batteries, inverters and charging controllers. With this basic understanding of solar power how it works, you are in a better position to determine if residential solar power is right for your house. Also, when talking to solar power installers and contractors you will be able to understand what they are talking about.

Solar Energy is a natural, permanent, continuous, renewable source of energy. Being the inexpensive, easily available source, it has tremendous potential that can be used for the welfare of mankind. But every coin has two sides…

In today’s world, Global Warming is becoming a serious issue slowly but steadily. Thus the usual modern technologies are also a part of the blame for the ascent of global warming. So, we should utilize the natural resources we have at our expense. The first most natural source that comes in our mind if we just look up during the daytime…!!! Obviously, we are talking about solar energy. It uses solar emission emitted by our sun, which is the storehouse of all universal energy.

It’s a renewable energy source that has been used over centuries in many traditional technologies. Solar energy can be used in a number of technologies and day-to-day usages like Heat (hot water, cooking etc.), electricity, transportation, and other innumerable important photochemical processes, which are totally reliant on solar energy. The scope of solar energy is immense; it can even be used to good effect in homes.

But like all great things the nature has ever seen, there are two sides of the coin. Here, as well solar energy being as useful and beneficial to mankind has some cons to. Lets discuss it in “light” of the topic! ….

Pros of Solar Energy

Solar energy like other modern technologies do not cost as money. Almost all the new technologies Science threw up in the modern era are not quite cost friendly even they may be of great convenience to us. But any one irrespective of their financial strength or weakness can afford solar energy, having no monetary attachments.

Since, the energy coming to the earth is much more than that consumed by us, the solar electrical power generation has the highest power density among all the renewable energy sources.

The modern technological may be wonder to few but they are also very much involved in developing a large chunk of the pollution in our earth, which harms us in the long run. Solar energy is efficient here as well as it is pollution free and eco-friendly.

Solar energy does not need fuel, thus saving us money as well as the possibility of polluting the environment by burning fuel.

Solar energy is clean, sustainable and doesn’t let out carbon dioxide, sulphur dioxide or other harmful gases which usually electric generation does. So, it doesn’t contribute to global warming, acid rain or smog.

Being eco-friendly, it also helps to decrease the harmful emission of the Green House gases.

There are no incurring costs, once the initial costing is taken care of, it is virtually maintenance free. And its easily expandable as well as most solar panels can be added required for a family or any machine.

Since solar energy can work entirely independently, it does not require any connections or anything, so it can be used effectively and easily anywhere. Systems can be set up anywhere, in remote locations as well. So, those locations can rely on solar energy even if the modern technologies don’t reach out to them. So, its very pragmatic & cost-effective for a new site.

Solar energy bolsters local jobs and wealth establishments. Thus it helps to fuel economies as well.

Cons of Solar Energy

The initial cost is very high. Means the installing costs can get costly, usually due to the high-cost semiconductor materials, which are used to build a solar energy system.

Solar electricity is presently costlier than the electricity given by other sources. Naturally as energy shortages are becoming common day-by-day, solar energy is thus becoming more price-competitive.

A Considerable amount of energy is lost when DC (direct current) has to be converted to AC (alternating current). The solar cells can only produce DC, thus the conversion by help of Grid-Tie Inverters incurs a loss of about 4-12%.

Solar electricity and heat are not available at night and also may not be accessible in case of bad weather conditions. So, a solar or complementary power station is required which maybe a problem for many locations.

Solar panels require a large area for installation in order to achieve a good level of efficiency. Besides the solar energy can also be influenced by the presence of water vapor, pollution etc. in the air, which may cause complexities.

So, all in all, solar energy is a very useful renewable source of energy, which may be the answer to the future for power, or energy needs, as global warming seems to pick up rapidly. So, we can all contribute to the environment by using solar energy thus erasing or trimming down various gas emissions, which can endanger earth, in turn, the millions of people in it. But there are a few disadvantages, which should be kept in mind as well. But one thing for sure, Solar energy is may be one of the oldest and one of the most effective energy sources which if used carefully, can help us emphatically.

Installing a home solar power or wind power alternate energy solution saves money and saves our environment. This article summarizes the typical solar power components.

As we all know, the world is currently facing a significant energy crisis. As such, it only makes sense to make the slight up-front investment in an alternate power solution at home. Not only does it help the local energy crisis struggle, but also helps save power for the entire world. Installing a home solar power or wind power alternate energy solution saves money as well saves our environment.

Among the alternate power solutions, the home solar power system and the wind power system are the most popular and are becoming more cost-effective and far less cumbersome than in the past. Wind power is one great solution, just not all of us can deploy it at our homes because of minor requirements. To implement a wind power system, we need a fairly large area and have an average wind speed of the area at least 11 miles per hour. Although these requirements are very easy to meet for most, in comparison, the solar power system is typically easier to implement. The only requirement is an abundance of sunlight.

A complete solar power system can have many different elements. Typically, people implement a few or all of these components, as needed. A few of the most common components are as follows :

Solar Cooker: A solar cooker is one of the most popular solar energy system that is typically used in homes. It has several advantages :

No use of fuel : solar cookers do not use any fuel other than sunlight, which keeps you saving power and decreasing those electric bills.

No polluted emissions : solar cookers do not emit any gases to the atmosphere nor does it produce residue. It makes for the most eco-friendly cooking system.

Variety of cooking : You can roast, boil, and bake, etc!

Healthy cooking : The food prepared by means of a solar cooker is very healthy. You can typically prepare meals for family of about 5 in a small cooking box all at the same time.

Solar thermal system : Installing a solar heating system or solar thermal in your home can provide your home’s temperature requirements. It allows you to maintain a steady temperature in your home without the worry of electric bills. Due to its increasing popularity, heating systems have become not only cost-effective but also aesthetically pleasing.

Solar generator : A solar generator is simply a device that can run all your electrical appliances and more utilizing our earth’s free solar energy. This device can convert solar energy into electrical energy by means of solar cells called photovoltaic cells, storing energy in these cells for later usage. A solar generator is sometimes also referred to as the solar lighting system. Simply put, installing a home solar generator is such a wonderful power-saving and cost-effective idea. Just think of getting all that free electricity!
