Solar Power 4u | Solar Panels | DIY Solar Panels

Solar power is the power extracted from the sun’s energy, which is the sunlight. As the sun provides us sunlight for free, solar power itself too is a renewable, clean and environment friendly source of energy. With rising concerns about depleting fossil fuels and rise in air pollution, the use of solar power as an alternative source of energy is fast gaining popularity. By harnessing and using solar power at home, it is possible to cut down the cost of power bills and extensive use can even make one totally independent in terms of power requirement. This is mainly because sunlight is available for free almost round the year and the best part is that solar panels and other such solar equipments require little maintenance.

But now, one million dollar question arises- that is why, in spite of so many benefits, are people using solar power only sparingly? The answer to this question lies in the fact that the solar powers are largely inefficient. To counter this problem, bigger panels have to be installed and this makes using them cumbersome. Also, some people prefer not to mess with the aesthetic beauty of their houses. Also, the solar panels do not come very cheaply. Moreover, there is the inherent problem of unable to work at night and providing very little power during cloudy days.

With the depletion of fossil fuels, the scientific community has been urged to understand the urgent need to consider upgrading of existing solar panel technology. Now, with continued research and development in those areas, the solar power systems have undergone drastic changes. They have figured out how to make cheaper solar panels and also improve their efficiency.

One of the major milestones achieved in the solar power technology is the invention of photovoltaic cells. They have gone a long way to reducing the size and increasing the efficiency of the solar panels. In a solar panel, the photovoltaic cells are placed on a steel substrate. Each cell is capable of capturing various spectrums of sunlight. The solar photovoltaic panels have overlapped layering of the cells which makes them an efficient source of producing power. The new solar photovoltaic panels use amorphous silicon thin alloy technology.

This solar photovoltaic panel based on the new technology is not that bulky and can be easily placed on the roof of houses. It is many times more efficient than a regular solar panel. Moreover, they don’t look that bad and can be easily implemented without affecting the overall looks of a building.

Another milestone in the road of solar technology is the invention of photovoltaic shingles. They are basically nothing but solar panels which are modified and made into shingles. Photovoltaic shingles can be used as a convenient and aesthetic substitute for large and bulky solar panels. They are implemented in the roofs of houses as normal shingles. They are usually black colored and have the appearance of normal shingles. And they serve the dual purposes of adoring your house as well as harnessing solar power and converting it into electricity for your use. Moreover, they save you the cost of buying extra shingles. In a nutshell, they are good looking solar panels.

Experts have said that the technology of using photovoltaic cells and photovoltaic shingles is a major breakthrough in the harnessing of solar power. Research is going on for further development in the solar power technology and you can expect even smaller and more efficient solar power systems made available in the near future.

Solar panels can be made to harness the reservoir of energy of the sun to some other type of energy. Generally the power that results will be available in the form of heat (to heat a building for example) or electricity which can be used to power anything from a radio to a complete business.  In this article we are going to talk about the bigger residential and industrial panels which are designed to provide power for the  home or business, where these panels are regularly placed on the top of the home or in close proximity to the home if space permits. We are also going to focus on the type of panels that generate electricity known collectively as Photovoltaic panels.

Solar panels are a terrific way to cut energy costs and to reduce your carbon emissions, and to become more self-sufficient. They are now becoming extremely popular in urban areas where alternative energy advocates and law makers are creating incentives for this friendly and quiet alternative energy source. The state of Colorado, for example, has been offering massive rebates on the up-front cost in acquiring and implementing a residential solar system.  After the panels are installed, energy from the system will be used to energize the house, or, when energy is being made in excess of demand, diverted for use on the grid, where it is purchased back by the electrical power company. There may be times when you are actually making income from your panels. With rebates factored into the initial cost it will generally take from seventeen to twenty-four years to get back the initial expense, at which time you will essentially be generating power from the sun at no cost.

One little-known fact, however, is that solar panels are initially contributory to greenhouse emissions because it takes power to manufacture a solar panel, that this energy is very often fossil-based, and front-end loaded, and that therefore there is a time period during which the solar panel has actually added to carbon emissions rather than detracted from them. Until such time as the solar panel has produced energy equivalent to the energy used to manufacture it (its fossil-emission payback period) it is actually a contributor to greenhouse gas emissions. This fossil-emission payback period is generally considered to be five to ten years.

Low power solar panels are normally available in 12 v or 14 v configurations, while high power  panels are available in 24 volt. As solar panels are DC, you may normally need a power inverter that changes it from low-voltage as Direct Current to another-voltage Alternating Current to change it to be compatible with the voltage and type that feeds both the home and the grid.

Conventional solar panels are constructed using twin sheets of semiconducting silicon, combined with phosphorus and boron atoms. Amorphous silicon solar cells are a highly powerful, emerging array of photovoltaics that differ in output, structure, and manufacture than traditional photovoltaics that use crystalline silicon. The H-AS solar panels are produced in the same way, but they are made just 1 micrometer in depth by laying down polymorphous silicon at very high pressures and temperatures.

Solar panels are normally maintenance free and many manufacturers will supply a guarantee of electrical output often for as long as 20 years.  Solar panels are installed on whichever side of your house that gets the maximum solar exposure. In locales south of the equator this would be the north-facing aspect, and in locales north of the equator its the south-facing aspect.

Perhaps you are happy with the status quo of today. Perhaps you feel all is fine and you don’t feel the need to change a system that’s worked for over a century. If you do, consider a few of these benefits to solar power and you may just recognize its potential in a somewhat more responsible, yet selfish, light.

I don’t care about the environment?

Perhaps everything in the world is fine with your life. The last thing you care about are trees, fresh air and clean water. Heck, the water shows up every time you turn on a faucet, the heat comes on when it’s cold, the light switch brings you light. What’s there to worry about? Consider that this is just the problem. If you don’ t care for the environment, the faucet may not bring you clean water, the heat may not go on and the car certainly will not start. If the environment is kept clean and left to do what it was intended to do, everything will continue to work fine. But get in its way and everything you thought was fine won’ t be for long.

One way to accomplish the goal of keeping all the comforts of home working properly is by using other sources of power generation like the sun, not generating nasty things that get in the way of the environment doing its job. Current sources of power come from dead things like old forests gone millennium ago. Environmentally responsible power, heat and transport come from living or energized things like water and oxygen molecules. Sun can be turned into electricity and used to power your car, heat your home and generate your light. But to make the process work, you need to be able to see the sun, which means caring for the environment and not getting in its way.

Cost savings

One of the best things about caring for the suns ability to do its job is that it saves you money in the long run. Once solar systems are purchased and installed, they cost little if anything to operate. In most instances, the government will even help to pay for the upfront costs of installing the system through tax incentives. Additionally, power companies in most regions are required to pay you for energy that you have generated and not used. Yes, you read correctly, the power company will pay you!

Profitable

In most instances, 70% of the northern hemisphere can generate enough solar power to run and heat their homes with existing solar systems. This means that whatever is left over goes back to the power grid if you so choose. Just think of your power meter running backwards. The extra power you need for that cloudy day is stored in ever more efficient batteries. Most current users indicate that the use of solar systems only takes a little thought in power management.

Off the grid

Depending upon how you feel about the topic, one of the better reasons to use solar power is that you can take yourself off the “grid” so to speak. Many people don’t enjoy being a part of the social collective that is interconnectivity. Going solar takes you away from this one aspect of community and puts you closer to self reliance.

Versatile

Even though the solar power generation systems of today have come a long way to providing power, heat and a host of other services there is a long way to go. This is not to indicate, however, that solar power is not currently versatile in form and function. Solar panels can currently be formed into thin sheets to for car top electric powered cars. They can cover suburban rooftops and not be noticed, unlike those 1970′s units. Costs are also coming down almost as fast as the flat screen TV’ s of today. Flat screens that solar power can power up through the use of a process called photovoltaic’ s.

Personal responsibility

Past the cost savings and environmental benefits that solar power brings you should consider using it because you are part of a larger social order that will procreate. The human species has not been around for all that long and is doing its best to end its run in one way or another. If you would like to give your children’s children a better shot at continuing the human species run on this planet solar power is one small contribution that you can make all by your little self.

Solar panels can be a great help to sailors, keeping vital lights and appliances functioning, even when batteries run low or a generator malfunctions. They are also a much quieter way of recharging batteries!

Learning how to install marine solar panels will be vital for the sailor who wants their advantages, but first he or she must learn which solar panels are best. Three types of solar cells are commonly used in solar panels, each with its own advantages. The sailor needs to learn these advantages and select the solar panels that are best for the need.

Types of Solar Panels

Solar panels must be kept from shading, as shaded cells draw energy for themselves from other cells.

1. Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection.

2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection.

3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be especially important on a sailboat.

Marine solar panels are available in both hard and flexible types. Hard solar panels can be attached to the deck, while flexible solar panels might be attached to deck or canvas.

Size and Number of Solar Panels

Learning how to install marine solar panels will include calculations to determine what size and how many solar panels you will need. This information is readily available on the Internet by searching the question: “What size solar panel do I need” on your favorite search engine. The rule of thumb is to allow for 20% more solar panel power than you estimate you will need.

Placement of Solar Panels

Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the boat’s configuration and size of the panels. Take your time and think it through. Read the instructions that came with your solar panels. You will want to avoid all violations of warranty terms.

The simple answer to how to install marine solar panels is: in the sun. Select locations that will get maximum sunlight without shaded spots.

In placing marine solar panels, consider the use of extra bars/braces to secure the panels. You obviously want them to remain stable.

How to Install Marine Solar Panels

Your marine solar panels should have clear instructions for installation. In addition to those, consider the following.

Most marine solar panel systems have three main components:

1. Solar panels to collect sunlight and produce a charge for you.

2. Charge controller to regulate the charge entering your battery and avoid overcharging it.

3. Batteries to store the energy your solar panels created.

Once marine solar panels have charged your batteries, you can use that energy to run most 12 volt DC appliances. These might include your safety lights, regular lighting, pumps, and fans, as well as small appliances. If you add an inverter, you can also run 120 volt AC appliances such as a microwave, radio, satellite dish, or radio. An inverter is a separate unit, not mentioned above, that transforms the current coming out of the battery into that required by most appliances.

First off, check to see that the system has a voltmeter. If it does not, purchase and install one. This will allow you to check the charge you are getting.

Affix your solar panels securely in place, and connect them per the instructions included in your kit. Use only tinned marine grade wire running from the panels to the batteries. If you are unsure of the wire you are considering, ask questions. Regular automotive wire may look similar, but in marine conditions, it will lose its ability to conduct electrical power.

Helpful Tip

Pre-packaged marine solar panel kits take the guesswork out of installation.

A solar pool heater enables you and your family to enjoy your swimming pool or outdoor spa for a greater part of the year. Into spring and autumn. And into cooler mornings and evenings. When others are shivering!

There are four ways to heat your pool

1. Electric heater
2. Gas, usually a propane heater
3. Using a pool cover
4. Solar pool heater

The solar solution is best. It’s cheap to run and you don’t contribute to greenhouse gas emissions. A guilt-free time in your comfortably warm pool or outdoor spa! Why not.

A commercial pool heater can cost you up to $2000. But you can build your own at a small fraction of that cost.

Just look around on the web for guides that give you clear instructions of how to build your system. There are several.

Be sure to look for these essential elements at least, in any guide you buy:

• A clear list of materials with step-by-step instructions
• Materials should be easy to source locally and be inexpensive
• No requirements for complicated engineering, electrical skills or welding
• Clear diagrams
• Some troubleshooting suggestions

How do solar pool heaters work?

They run on a passive solar principle.  Simply, pool water runs through long lengths of flexible tubing. These are suspended in front of reflectors to receive and transmit the sun’s warmth to the water in the tubing. The tubing should be protected, say with with polythene sheeting, from any wind chill.

The reflectors can be made out of halved storm water piping, sprayed with chrome paint to maximise their reflective powers. To circulate this warmed water through your pool or spa you will need a small pond pump or solar electric pump. The latter is more expensive, but obviously you will help the environment and your wallet by spending a little more to start with.

One guide suggests that minimum pump specifications should be that it delivers 10 litres per minute (120 gals/hour) and is capable of raising water to 1.6m (5’2″).

All components, containing tubing, reflectors and cover, are assembled into a solar panel. Its ideal size depends on optimum dimensions for ease of handling, structural integrity and heating efficiency. Of course more than one panel can be used. A spa would not need a large panel. But then again… some like it hot!

In general, a panel measuring 3.4m (11′ 4″) by 1.4m (4′ 8″) is effective on pools up to 30,000 litres (6000 gal).

Panels should be placed in such a way to maximise receipt of the sun’s rays. It’s best to have them face the sun’s mid day position. Place them vertically on a fence or horizontally on your roof.

To make the best of your solar pool heater, it makes sense to use it with a solar blanket. But this is not normally required to benefit from your now upgraded asset.

Give it a go! Your family will thank you for it.

The history of solar panels can be dated back to 1839 as this was the period when French physicist Antoine-Cesar Becquerel made the astonishing discovery of the photovoltaic effect. This surprising discovery took place during an experiment that involved an electrolytic cell made from two metal electrodes and was placed within an electrolyte solution. Antoine-Cesar Becquerel discovered during the experiment that when the electrolytic cells were exposed to light, it produced a certain amount of electricity. The more the light, the more the production of electricity and that is how solar panels actually came into the picture.

Almost 50 years later in 1883, the first solar cell was developed by Charles Fritts and it was formed using selenium coating sheets with a micro-thin layer of gold. Between the period of 1883 and 1941 there were several scientists as well as inventors who with the help of companies started experimenting with solar energy. It was during this period that Clarence Kemp, an inventor from Baltimore patented the first ever commercial water heater that was being powered by solar energy. Apart from this, the great scientist Albert Einstein also published a thesis on photoelectric effect and within a short period of time received the coveted Nobel Prize for his thesis and valuable research.

Around 1941, an American inventor named Russell Ohl who was working for Bell Laboratories patented the first ever silicon solar cell. This new invention was spearheaded by the Bell Laboratories and they went on to produce the first ever crystalline silicon solar panel in the year 1954. This was the most effective solar cells in that era as it achieved a 4 percent return on overall energy conversion. In the next few years several scientists from all over the world continued their research, study and experimentation to improve upon the original solar cells and started producing solar cells that gave 6% efficiency on overall energy conversion.

The first ever large scale deployment and use of solar energy ever recorded was in space satellites. USA was the first country to enable production of solar cells that gave 20% efficiency and this was in the year 1980. By 2000, USA had produced several solar cells that were producing 24% efficiency. Last year, two large companies, Emcore Photovoltaics and Spectrolab rose to dominate the world of solar cell production by producing cells that gave 28% efficiency.

Working of Solar Panels

The solar panel basically consists of pure silicon. Silicon is first stripped of all its impurities and hence provides the most ideal neutral platform for enhancing the transmission of electrons. In its natural state, Silicon can carry at the max four electrons although it has the ability to carry eight. So mathematically speaking it has enough room for 4 more electrons.

When a silicon atom is made to come into contact with a second silicon atom then each of them receive each other’s extra four electrons. So the 8 electrons satisfy a single silicon atoms’ needs and this results in the creations of a strong bond but the fact is that there are no negative or positive charges. To produce a large piece of pure silicon, the silicon atoms have to go through the process of combination for years. Once the pure silicon is ready, it is applied on to the plates of solar panels. When silicon is combined with other elements then it produces a positive or negative charge.

Solar panels are being looked as the provider of tomorrow as the other forms of creating electricity are getting replenished by the day. There are several online sources and websites who are selling solar panels with a power range that varies from 10WP to 280WP.

There is much debate about the application of solar energy as a global energy platform. There is no debate, however, on smaller applications such as pool lighting.

Converting to Solar Lighting For Your Pool

Solar energy has been used by man since the beginning of time. The power of the sun, and its ability to warm the Earth, has kept civilization alive. In the 1830′s, John Herschel, a British explorer, used the first modified solar collector to cook food on an African expedition. Since then, man has come up with other ways to harness the sun’s power in both big and small amounts. One of the smaller ways that the average person can use solar power on a cost effective basis is for pool lighting.

Many homeowners employ the use of pool lighting so that they can enhance the look of their backyard, as well as use their pools at night. Unfortunately, traditional lighting is either a drag on your electric bill or a pain in the derriere if you go the battery route. In the case of floating pool lights, you’re stuck with batteries   which make them a time consuming to change out and costly item to run. Batteries need replacing, and they are also harmful to the environment if not disposed of properly.

You might be wondering if there are any other options for illuminating your pool that are more cost effective and easier to work with. There is an option that solves all the problems   solar pool lighting. These lights work by floating on the surface of the water. All day, they collect the sun’s energy via solar collectors located on the top of their waterproof case. The collected solar energy charges a rechargeable battery located within the light, and then the solar pool lights are turned on automatically at night via a light sensor. The stored power within the battery powers a LED light which takes very little energy to run   therefore, the pool light can stay on for eight to ten hours at a stretch.

Going with solar pool lighting may seem a small step in the duel battle against the utility bill and fossil fuel usage. In truth, every little step we take as a society helps. Remember, changing even one light bulb in your house to an energy efficient version saves money and thousands of tons of pollutant from fossil fuel energy production. If we all convert to solar pool lighting, it will make a difference give the sheer number of pools.

The most exact definition of Solar Energy is plainly “the energy from the sun”. It is a term used to classify the electromagnetic radiation emitted by the sun and intercepted by the Earth. It is the world’s most permanent and reliable source of energy and the most copious.

The uses of solar energy on earth include solar heating for buildings, solar heat for manufacturing or industry and electricity production. So what is solar energy? How does it affect us?

Solar energy is responsible for weather systems and ocean currents. It provides light, heat, and energy to all living things on Earth. It has many uses. It supplies electricity; it can be used to power cars.

Solar energy is also used as a power for satellites in space and in space shuttles. It could also power boats, generators during emergencies, toys, and even security systems.

The amount of solar energy that the earth receives is about 770 trillion kilowatts (kW), an amount 5,000 times bigger than the sum of all other energy, may it be terrestrial nuclear energy, geothermal energy or gravitational energy.

There are two types of solar energy. These are:

1. Thermal Energy
2. Electric Energy

What is the difference between the two types energy?

Thermal energy is kinetic energy. It is everywhere. It makes the earth hot and even heats up our homes. It helps us to dry our clothes. It is used as well to heat up water for household use or even pools. That is why thermal energy is called the heat energy because it is stored in the center of the earth as well.

Electric energy is widely known to us as the electricity. It is an essential part of nature and it is one of our most widely used forms of energy. This uses sunlight to power ordinary electrical equipment, such as household appliances, computers, and lighting.

Most applications of solar energy depend on systems including collectors, storage and controls. Storage is needed for a reason that solar energy is only available at daylight hours, but the demand for energy is needed both day and night. Controls are used to guarantee that the storage system works safely and efficiently.

The accessibility of solar energy is determined by three factors:

1. The location is usually measured by latitude, longitude and altitude.
2. The time.
3. The weather.

Aside from knowing that solar energy is a free energy still, you have to realize that it also has advantages and disadvantages.

The advantages are:

Solar energy is almost limitless; it will be available for as long as there are still humans in the earth.

• It is abundant. You will not worry of running out of it.
• It could provide more power than all known fossil fuel reserves.
• Solar energy is available during the day when electricity usage is really important.
• It is the most inexhaustible, renewable source of energy known to man.
• Solar energy can be absorbed, reflected, transmitted, and insulated.
• It can be collected and stored in batteries.

The disadvantages are:

• It is not suitable in cloudy areas.
• It is not available at night time.
• And it may require large land areas.

As a reminder, solar energy levels are lesser the farther north the site. Considering geography, season is an important determinant of solar energy levels because the Sun’s position and the weather vary greatly from summer to winter.

When we talk about renewable energy we are referring to power that delivers energy from resources that will not be depleted because of our use of them. Renewable energy is an alternative to non-renewable fossil fuel energy for reasons other than the factor of non-depletion.

One basic benefit of renewable energy, and the reason environmentalists all over the globe are advocate its use, is that it does give off greenhouse gases and other harmful pollutants as do the by-products of burning fossil fuel for energy. Renewable energy such as solar power, water power and wind power, while the widespread discussion of which is new, are anything but new.

In both newly developing and highly developed countries wind, sun and water have long been used as power sources, though not to the extent of providing the primary energy source for large metropolitan communities.

The mass production of such renewable energy is become commonplace in recent years as more and more people come to realize how climate is changing due to the pollution of fossil fuel gases, due to the exhaustion of the availability of these fossil fuels and the political and social concerns of energy sources such as nuclear power.

Many countries and non-profit environmentally-conscious organizations are encouraging the use of renewable energy sources by passing legislation on tax incentives for their use and subsidies to offset the added expense of converting from fossil fuel to renewable energy.

The flow of renewable energy involves phenomena that occur naturally in our world. Tides, sunlight, wind and heat derived by geothermal occurrences all provide renewable energy. Each of these energy sources is unique both in where we can use them and how.

Most technology that converts renewable energy into power sources we can use are powered at least in part by the Sun if not directly at least indirectly. The earths atmospheric system stays in such equilibrium that the heat that it gives off radiates into space to an amount equal to the radiation that comes to earth from the sun.

The result of this energy level within the atmosphere is roughly translated to the climate of the earth. The water of the earth, also referred to its hydrosphere, absorbs a lot of the radiation that comes to us from the sun.

Most of the radiation gets absorbed at the lower latitudes of the earth that exist around the equator. This energy gets dissipated all around the globe, however, in the form of ocean and wind currents.

The motion of the ocean waves might have a role in transference of mechanical energy between the ocean and the earths atmosphere by way of wind stress. Solar energy also provides the means by which precipitations is distributed and then tapped by hydroelectric energy projects as well as plant growth that then creates biofuels.

Did you know that solar power is a renewable, clean and cheap source of energy?

Once the mystique is removed from the idea of using solar mirror to produce power people will began to understand how it all works. This will lead to people seeing how using solar mirror to produce power can be looked at as a viable alternative source of energy. In fact in this choice of solar power the largest component is the sun. Scientist and those in the private sector are even now looking for ways to make using solar mirror to produce power in homes and businesses more economically feasible

HOW DOES IT WORK?

When considering the choice of using solar mirror to produce power you should understand how it works right? Well if you can imagine that it works much the same way that leaving your garden hose laying in the sun all day on a hot sunny day. When you go to use it the first thing that comes out is hot water having been heated by the sun all day.

This is a simplified version of one way to utilize solar energy. There is usually a water container that collects the sun’s rays in the form of heat. After this is heated to a pre-determined temperature it is then properly utilized elsewhere.

Some common applications of this have been to heat water in swimming pools and ponds with water moved into large containers that are basked in the sun all day. The mechanism will then move the water back into the pool or pond once the water reaches a preset temperature which in turn helps heat the rest of the water. This of course has been utilized in more commercial applications as well.

Did You Know?
Approximately more than ten thousand homes in the United States are entirely powered by solar energy.

Another way that is properly thought of when considering using solar mirror to produce power gathering solar power through photovoltaic cells that in turn convert energy obtained from the sun DIRECTLY into electricity. This electricity produced is in Direct Current or (DC) format. This (DC) can then be stored directly into storage batteries. After this (DC) is converted to Alternating Current (AC) it can be used to operate lights and any other common appliance.

INTERESTING FACT:

Silicon from just one ton of sand used in photovoltaic cells could produce as much electricity as burning five hundred thousand tons of coal.

There are areas that have more average days of sunshine, like the southwestern part of the United States, where using solar mirror to produce power can be a good source of power. When you couple this with the fact that you are dealing with solar power which is clean, cheap and renewable it just makes sense. However, understanding how it works , you can see how using solar mirror to produce power may not be a good solution in areas of the country with several days of overcast skies and insufficient sunlight.
