The Many Benefits of Homemade Solar Energy

Many people today believe in the importance of going green. As a matter of fact, there are cars right now that are environment friendly. There are also a lot of campaigns against air pollution, burning garbage, etc. When it comes to electricity production, there is also a way to go green. By depending on homemade solar energy to bring electricity to your homes, you will be able to have a more harmonious relationship with mother earth.

Using electricity provided by solar power has so many benefits. Aside from promoting eco-friendliness, it also aids people in saving on electricity charges. Solar power is also renewable which can bring about energy conservation, becoming one way of ensuring that fossil fuels do not immediately run out. Solar power produces both heat and electricity which are two very important elements that we need to survive. By constructing and using the so called solar panels, we can gain solar power, which means that we can get power into our homes in a more efficient way.

Perhaps the most interesting benefit of solar powered electricity is the fact that users get to provide their own energy, thus decreasing the need to rely on utility companies. Bear in mind that almost every year, electricity rates go higher, forcing us to shell out more money every month. With solar panels, however, rising electricity charges may not have a bigger effect on people.

Some people may have second thoughts about using solar powered systems because of the cost to purchase and to have it set up. Having solar panels installed in your home may sometimes reach the cost of thousands of dollars. However, when you think about the benefits and the total percentage of savings you get yearly, having a solar powered system can be better than paying utility companies just to get electricity.

Nowadays, there are also solar panel kits available that are not that heavy on the pocket. To save on money, you may also choose to install the system yourself, especially because the kits normally come with instruction manuals that you can just follow in order to successfully install a solar powered system by yourself. By installing a DIY kit, you may not need to hire professional installers, thus, you get to save money. There are also some government programs in a number of countries that provide rebates and sometimes tax credits to people who use solar panels which also means more savings.

The demand for homemade solar energy is little by little rising because of how advantageous it is. A lot of manufacturers are now able to offer less costly solar power systems. There are also different types of solar panels that can give you the choice of which solar panel is best for your home. If you want guaranteed efficiency and savings, find out first the total amount of power you need, the amount of sunlight you get in your place, etc before purchasing solar panel kits. Look for systems that are easy to afford, easy to buy, and proven effective.

Solar Energy Negatives

Change is a watch word for our planet, and changes have been made that have enhanced the Earth. Scientist are exploring the negative effects of solar energy in order to safely replace the energy sources that we presently use with this form.

Solar energy has the ability to give us cheaper if not free electricity to our homes through the use of solar panels. However, before you jump on the band wagon and go out and try to start this new power trip there are a few things you should know. There are some people who believe there are many negatives to solar power.

Many people believe that thermal solar energy has many health risks when it is used to heat water and the air in their homes. This can happen when it has not been set up properly or the manufacturer made errors when producing it.

If it is unable to store the water properly it can cause fungus and molds to grow making anyone who drinks or uses the water sick. To make sure that this does not happen you can make sure that the units used to store the water have been built from materials that are made to prevent this.

PV solar energy also as health risks that you need to be careful of. PV (photo-voltaic) panels require millions of silicon dioxide in order to be used. That number is lowered when they are exposed to heat. The materials that are released during the refining process will increase the rate of toxicity and can affect your health. This is one of the more serious negatives of solar energy that is responsible for eleven to twenty one deaths per each quadrillion joules of energy that are created.

But do not let this deter you completely. Study up on the different types of solar panels and the negatives as well as the positives. You might find that they are worth it in the end.

How is Solar Energy Used

We simply need to think back of the last time we lost power when we had to light some candles and wash ourselves with cold water. Luckily for us the power came back but what if it didn?t come back. We have to stop thinking that everything lasts forever because nothing does and the sooner we realize that, the better we will be, it is time to start thinking outside the box, and look up high above into the sky and realize that solar energy is here for us to use. It shines 24 hours a day, 7 days a week non stop around the world, it is here now and for a long time to come.

The sun is a very intense ball of fire or gas way up in the atmosphere. We only see it when we are awake but on the other side of the globe others also get the daytime when we get the night. Did you know that some people use a great deal of the heat generated from the sun in order to heat their homes, power electricity and provide hot water to their love ones and businesses. Thinking about all the machinery that runs with electricity, it is hard to imagine running it by rerouting the sun to the machinery. Scientists have started to make this possible by utilizing this free energy to power everything from, home heaters to heating water, from powering home appliances to electronic devices and even the space shuttle is using solar power.

This solar power energy can be redirected and concentrated using special boxes (solar panels) that attract the light during the day to heat water and homes throughout the night. Solar power is becoming very common, extremely important and provides a natural way to heat, collect electricity and heat water with just a little more effort. We live in changing times; in the future we may have no other choice but to look at natural resources in order to have these necessities and conveniences. To have a home solar power system installed or have one made yourself can save you a huge amount of money and the investment you made to modify you house to implement a solar system can pay itself off many times in a short period of time. Solar power is important now and in the future.

Is Solar Energy Reliable?

Solar power is becoming a way of life for many people across the globe. From isolated communities to inner city suburbs, solar energy is becoming a very popular choice to better the environment.

Solar energy has been in existence ever since life on our planet began. We have been using the strength of the sun in many different ways, past and present. The more modern technique of using solar energy has been through the use of solar panels.

Solar energy is 100% reliable, if our planet did not receive this energy, or if the energy increased or dropped significantly, then the earth would more than likely struggle to support mankind. However, some methods regarding how we use solar energy are by no means 100% reliable.

The more modern method of harnessing solar energy has been through the use of solar panels. The technology used to turn sunlight into electricity is still in its infancy. Newer and better technologies are emerging every year, and one day we can be hopeful that solar panels could easily support a large household in a reliable way.

Many people have had great success using solar panels to power their home, and this can be down to a range of factors. The main problem associated with the reliability of solar panels is the cost. Due to the more expensive panels been out of the price range of your average consumer, more and more people are opting for budget solar cells, which provide a much lower output, resulting in the disappointment of the consumer.

The people who achieve a reliable and efficient power output from solar cells either integrate these solar panels with a small home wind turbine or ground source heat pump.

The “green dream” is by no means a dream. We do have the technology available to provide 100% of a households power supply, yet cost is the bridge that places the green dream a long way away.

How is Solar Energy Produced?

In this day and age of growing technology, scientists are working diligently to find ways to harness solar energy in order to power the Earth. Producing cars and products powered by solar energy will reduce the emission of harmful gasses and chemicals into the atmosphere. Our Earth is a precious commodity and we need to take care to protect it.

What is solar energy? Solar energy is radiant heat and light that is emanated from the Sun. This light helps to influence the climate on Earth and allows not only humans and animals – but also fish to live. Solar energy has been harnessed for power since the ancient times by humans through the use of different technologies.

The Earth can receive 174 petawatts of solar radiation or insolation in its upper atmosphere. Close to 30% of that is reflected back into space and the rest is absorbed by the clouds, land masses, and the oceans. The spectrum of solar light on the surface of the Earth is predominantly spread across near infrared and visible ranges and a small part in the near ultraviolet. The solar light that is absorbed is able to heat the land surface, atmosphere, and oceans.

Solar energy as well as hydroelectricity, wind, and wave power make up 99.97% of the renewable energy that is available on the Earth. The total amount of solar energy that the Earth?s atmosphere, land masses, and oceans absorbs is close to 3,850 zettajoules a year. Studies show that in 2002 this was more energy in one single hour then what the world would use in a total year.

The amount of solar energy that the Earth?s surface can capture is so large that in a single year it will be twice the amount that we can obtain from non-renewable resources of oil, coal, and natural gas. Because of this consumers themselves are seeking to purchase their own solar energy systems to help save them money and to keep the Earth safe.

What is Solar Energy? How it Works and Why

Solar energy is radiated from the sun through forms of heat and light, this powers the Earth’s climate and sustains life. Today’s technologies can make use of this energy resource. Simply, solar power is the conversion of sunlight into electric power. The technologies that are used to convert the sunlight into power are called photovoltaics, there are also other technologies that have been used such as concentrating solar thermal devices but a lot of the experimental devices such as thermal converters, solar chimneys and solar ponds have also been used.

Solar energy is a much safer and energy efficient way of creating electricity, the use of solar energy has now become an important component to consider when designing a building. This is what thermal mass is used for; because it preserves the heat that the sunshine delivers to the building and can then transfer that heat into electricity. There are also solar water heaters which are a much more efficient way of heating swimming pools, and are a great idea for large hotels and sports pools, which use up a lot of the earths non-renewable fuels.

We also use solar power in agriculture, in particular greenhouses, in case you’ve always wondered what they are for, now you know, because they grow specialty crops, which are difficult to grow out side in the normal atmosphere, instead, the greenhouse uses the photovoltaics, which cause the plants to photosynthesize, which causes them to grow faster and stronger. There are also photovoltaic-powered water pumps for grazing cattle. There are also evaporation ponds which can work in the city and in the country; they are used to harvest salt and clean streams of contaminants.

In the poorer areas of the world, solar distillation and disinfection techniques produce potable water for millions of people. Also for families, and large buildings, family-scale cookers and larger solar kitchens concentrate sunlight for cooking, and in the more industrial work places, more sophisticated concentrating technologies magnify the rays of the sun for high-temperature material testing, metal smelting and industrial chemical production. A range of prototype solar vehicles provide ground, air and sea transportation.

How do the solar power technologies work? Here is an example:

The simplest form of solar energy collection is the FLAT PLATE COLLECTOR, this is a long flat rectangle which ideally would be fixed on to a roof or building in a sunny area.

Dark metal plates absorb and preserve the heat. Coils of tubing are looped throughout the collector, next to the metal plates with air, water or an anti-freeze solution circulating within them. The heat is transferred into the coils and thus the fluid/air as it circulates through the tubing. The air or fluid is either used immediately (as hot water or to heat a room, pool, etc.) or it is transferred to a well insulated holding tank for later use.

These are capable of reaching temperatures of 82 degrees Celsius which is great for heating water or a room.

What Are The Drawbacks From Using Solar Energy?

What are some drawbacks from using solar energy? I know that it is expensive, and it only works when the sun is out, what are 3 other drawbacks?

The Importance of Solar Energy to our Everyday Lives

Daily headlines make everyone aware of the dangerous situation in which our environment must operate. The human population has historically overtaxed its natural resources and today we are seeing the long-term effects of this selfish behavior. While many people try to reduce their ?carbon footprint? by recycling, spending their money in more effective ways and eating a more ?earth friendly? diet, one of the most important practices we should all begin is improving our energy efficiency.

One of the most well developed methods of becoming energy efficient is through the use of renewable energies such as outdoor solar lights. In fact solar power is the best developed and most broadly applied of the modern energy technologies and almost anyone can use it to reduce their traditional energy consumption.

How? It is actually quite simple to recognize the ways in which the sun?s energy can be put to use in even the most basic methods. For example, during the hot summer months a home owner or apartment dweller could close all window blinds, curtains or shades to reduce their need for air conditioning or home cooling. (Imagine a summer without warnings about ?rolling blackouts? because everyone has to keep their air conditioner turned to its highest settings simply because they allowed the sun to pound into the room all day long.) Alternately during the winter months they could easily rely on the sun?s warmth to heat up a room during the earlier hours of the day and then close the blinds before dusk in order to capture the remaining heat.

Those who have the financial means can use solar energy in a significantly wider number of ways, and not just to heat their domestic hot water or supply their homes with some energy. While such functions are ideally where all home owners should be headed, currently the materials and equipment required to convert a home?s energy supply entirely to a solar powered system are not within everyone?s budget or ability. Home owners can however employ a wide number of solar powered LED lights and appliances (including radios, solar landscape lights, ovens and attic fans) as an effective approach towards energy efficiency.

Finally, solar power has finally reached the automobile industry and several major manufacturers have promised consumers that they will make cars with rooftop solar panels available by the year 2010. While such vehicles may not be fully powered through solar energy it is clearly a step towards a healthier planet.

Solar Energy Explained – A Simple Guide

Science has proved that our Sun is a huge burning mass of whirling gases with tremendous heat. The heat is so intense that any object approaching within thousands of miles of the sun?s radius would instantly vaporize. The rays of Sun when they reach the earth bring with them the heat latent it them. This heat is diluted when the rays of Sun disperse in the whole atmosphere. But it is possible to concentrate the rays by a magnifying glass to such a point that the latent heat in them also gets concentrated so much that the object placed at that point starts to burn. In using a magnifying glass in the sunlight, what we effectively do is we trap the solar energy present in the sunlight and focus it at a point to produce heat. This principle is the basis of harnessing the potential of solar energy. This solar energy is present everywhere where the sun?s rays reach. We must try to trap this energy as much as possible so that long after the sunset, we can use it to warm our homes and hearths.

We may find the sunlight very pleasant to be in. If we continue to sit in the sunlight for a long time, we find our skin becoming hot because it absorbs the heat present in the sunshine. But since the sunshine is percolating every nook and corner where the sun?s rays reach, the heat is not felt easily. The heat gets dissipated with the atmosphere. That is why it is difficult to capture the heat in the sunlight to such a point that it can be put to use to provide heat and energy to its full potential.

To trap the latent heat in the sunlight sufficiently so that we can use it to warm our homes after the sunset, we need to use the principle in the magnifying glass, that is, we need something that will garner the heat of the sunshine and concentrate it upon a particular area. That something is a solar collector, just like a magnifying glass. It captures the sunlight falling upon it and allows the sunlight to pass through and into the area beyond it. The articles in the space beyond the solar collector absorb and capture the solar heat. The solar collector provides only a one way passage to the heat and traps it so that it cannot get back to its source. One example of solar collector is glass which allows passage of the sunrays through the glass and into container beyond it. The Sun?s rays making up the sunshine travel in straight lines so that once they are through the solar collector, they are not able to turn back themselves. Thus the solar collector effectively traps the heat energy present in the sun?s rays and the area under the glass becomes warm or hot. The articles in the area under the glass absorb the heat and prevent it from escaping back. Thus the area under the glass is heated by solar power and it remains hot for a long time since the heat is trapped there.

The greenhouses make use of this great natural solar collector, that is, glass. The glass walls trap the heat in the sunshine and the greenhouse remains warm long after the sunset or when the sunshine does not reach the greenhouse because of cloudy atmosphere. Thus the warm atmosphere inside the greenhouse is maintained even during cold seasons.

You Can Help Make Solar Energy Accessible

Solar energy is likely the largest, single answer to this nation’s dependence on fossil fuels. With enough solar energy, U.S. citizens can ignore the threat of Peak Oil, the more visible threat of oil embargoes from Mideast countries, the rising cost of fossil fuels and the air pollution that is making large cities virtually uninhabitable.

Getting to that goal isn’t easy. There are a lot of solar incentives out there, from utility companies sponsoring solar installation to local, state and federal governments offering funding or tax rebates to homeowners installing a photovoltaic (PV) system. Unfortunately, these incentives are all over the board, vary from state to state and even region to region depending on the utility, are rarely publicly advertised to make homeowners aware of their existence, and change from one year to the next depending on the whims of Congress.

Most homeowners, when presented with the 10,000 hoops required to get some kind of incentive package, shrug their shoulders and walk away. Life is complicated enough. If president-elect Barack Obama truly wants to meet his eco-friendly energy goals – five million “green collar” jobs, negative oil imports in by 2018, and 10 percent of energy coming from renewable sources like solar – he will first need to translate this mishmash of incentives into a cohesive, comprehensive and comprehensible national policy.

What if, for example, instead of searching DSIRE’s (Database of State Incentives for Renewable Energy) map for your state, then searching the more than 100 entries for a program that matches your qualifications and expectations, you could simply rely on the fact that state, regional and utility incentives all offered a specific program?

Better yet, what if an agency of the federal government, like the U.S. Department of Energy, took over all incentives and offered a flat rebate not subject to change every time Congress was in session? Can you imagine the numbers of individuals who – currently stymied by a maze of regulations and stipulations – would flock to install solar energy panels? I can, and it would give the solar energy industry a boost not seen since Henry Ford first introduced an affordable automobile.

You can make this happen by writing your representative and demanding a uniform, timeless, renewable energy incentive program. Better yet, join a social networking site and start your own petition, or contact renewable energy advocate sites (the American Solar Energy Society is a good start) and ask them to start a petition asking Obama and his transition team to develop such a program.

The future of solar energy is you, and tomorrow is already here.
