Solar Energy: Here Are A Few Essential Things You Must Know Before Building Solar Panels

Solar Energy: Here Are A Few Essential Things You Must Know Before Building Solar Panels

So, you think it’s time to make your own solar energy generator to cut bills or have a non polluting energy source for your home. Before you begin you need to know how it works.

Solar energy is made by rays of sun that reach earth in just a few minutes after they leave the Sun’s surface covering the distance of 93 million miles in a few minutes. After all, light travels with the speed of light. The atmosphere absorbs most of this energy and one third of the sunlight is reflected back into space. What remains is what we can use to create energy.

Did you know that the biggest solar battery on our planet is Earth itself? It absorbs about 174,000 billion kilowatts (kW) from the Sun every 60 minutes? All in all, by now you should know that the light produced on one square meter during a cloudless summer afternoon, is generating about 1000 watts.

Unfortunately, most of this energy is wasted. The energy that does not go to waste gives birth to the winds and sustains life. Plants use it to generate oxygen, animals and human beings need it to strengthen their organisms.

However, we have reached that moment in our evolution where we can harvest more energy from the Sun. You must know that the types of solar energy are direct or indirect, active or passive.

Direct solar energy is created when sunlight is striking a solar cell directly and electricity is generated immediately. It directly transforms, without any other process.

On the other hand, indirect solar energy needs one more step to change sunlight into useable energy. It’s the case of hydroelectric generators and wind generators, transforming solar-caused wind, rain and other climatic interactions into power.

We can change sunlight into some other type of energy by:

Solar thermal processes: Sun energy is changed into heat. During this process, the sun’s heat is absorbed by solar panels which then heat water which can be used to heat buildings. The solar panels are often placed on the roof or somewhere where they have more sunlight, and are introduced afterwards into a system of tubes called "thermal collectors" to the heating source.

Photovoltaic processes: Unlike the solar thermal systems, through this process, photovoltaic cells absorb the sun’s light and not its warmth, so sunlight is changed into electricity. They are viewed as the future of power generating technologies and are often silicon-based pieces of material. Solar panels are built of many of such cells, put together.…

Solar Decathlon House You Can Eat

Solar Decathlon House You Can Eat

Sounds crazy doesn’t it? But that’s exactly what is being accomplished in this year’s US Department of Energy’s Solar Decathlon 2011.

The Solar Decathlon which originated in 2002, occurs over a two year period and challenges collegiate teams to design and build houses that operate on solar power.

They must be attractive, cost effective, and most certainly, energy efficient and affordable.

Twenty teams from around the world, including the US, Belgium, China, and New Zealand are participating, creating a competition that is diverse both geographically and academically.

One of the most unique projects ever conceived will be presented by the University of Maryland this year. They call it the Watershed house and its design incorporates the use of a mini eco-system that captures and fully utilizes the energy from the sun, wind, rain, and even the household waste that contains valuable energy and nutritional resources. Also included in it’s design is an edible wall, although not a support wall I’m sure.

The house is laid out with two rectangular sections that are parallel to each other with the two outside opposing walls built higher which creates a roof that looks somewhat like a butterfly. The roof is designed for maximum sunlight and rainwater capture.

The structure itself is actually quite attractive and features:

– A roof top array of photovoltaic solar panels;

– The latest “smart” technologies to control ventilation, humidity, temperature, and light;

– An edible wall connected with a beautiful garden;

– Modern building materials that are pleasant to the eye.

Amy Gardner, an associate professor of architecture at the University of Maryland says: “Our goal for Watershed is to produce an eco-system whose efficiency comes from the interconnectedness of building, site, and the people who inhabit them”.

This is the fourth time a Maryland team has made it to the finals. In 2002, they took fourth place with a residentially designed house that demonstrated the practicality of using solar energy. The team improved on their solar house project in 2005 and received the People’s Choice Award, the BP Solar Innovation Award, and a Safety Award honorable mention. In the 2007 competition, their LEAFHouse was the best in the US and placed second overall, winning the People’s Choice Award. They also gained some industry recognition as they received the ASHRAE (American Society of Heating, Refrigeration, and Air-Conditioning Engineers) award for “Integration for Renewables for Sustainable Living” and the NAHB (National Association of Home Builders) Marketing Curb Appeal First Place Award.

Students can focus their attention and sharpen their skills by taking courses offered in Architecture, Agriculture, and Engineering by UM beginning in the fall 2009 and concluding in the fall 2011. There are plenty of extracurricular activities where volunteers can help also.

Students come from a variety of fields of study including architecture, architectural landscaping, and environmental science and technology. They are accompanied by a very divers faculty as well. As Gardner puts it: “This year, the project will benefit from the UM tradition of an integrated, inter-generational team, with voices both fresh and seasoned, encompassing a depth and breadth of mentors and students from varied disciplines.”

All of the finalists will have their projects on display at the National Mall beginning in October 2011. The National Mall is located in Washington DC and the site of the Decathlon is usually in close proximity to the Washington Monument.

Let me suggest that you take a tour with family or friends if you have some extra time or happen to be in the area. It is a free event and one that I’m sure will fascinate you while giving some valuable information with regard to our solar energy future as well.…

Home Solar Panels Buying Tips

If you want to reduce your household’s expenses, while ensuring you bring down your carbon footprint, investing in a set of home solar panels can be a good decision to make. Photovoltaic cells have come a long way since the first designs were made more than three decades ago. Now they have become a ubiquitous sight on our streets and homes.

There is now a lot of interest in residential solar energy systems. As the efficiency of the PV cells has increased, and the costs have come down, it is an option that is now being considered and chosen by hundreds of thousands of families. Though there is an obvious expense when purchasing and installing the panels, the savings that can be made in the long term are huge. Over a number of years the system pays for itself, and also offers the option of selling surplus electricity back to the national grid for a handsome profit.

Before you start contacting the various retailers and installation firms, it is worth understanding the differences between solar power systems. By doing so you should be able to ensure your money is invested in the most productive way.

Perhaps the biggest question, is whether to choose this alternative energy source to power your complete home, or simply to offset your demand on the national grid. Many households now choose to become self sufficient in energy. You can calculate how many panels you would require by analyzing the amount of units of electricity you have used in the last month and then comparing this with the amount of energy that can be produced by the latest PV cells, and also factoring in the amount of sunlight received on an average basis in your region.

One of the great aspects about a solar energy system is that they are completely scalable, this means that you can add more panels to the set up as and when your demands require. This allows for you to gradually increase the amount of renewable energy you use over the months and years as opposed to making a big switch at the initial stage.

It is also important to think careful about how the energy that is created will be stored. You will need to invest in an array of batteries, these can also vary considerably in design and specification. Find out which batteries can hold their charge for the longest and require the least amount of maintenance.…

Busting Solar Energy Myths – It’s Too Expensive!

Busting Solar Energy Myths – It’s Too Expensive!

The cost of production of solar energy components is rapidly getting cheaper and cheaper, but yet the cost to install a residential solar energy system still seems to be prohibitive – or is it?

Smoke And Mirrors

The U.S. government has historically provided subsidies to traditional (i.e. mature) energy sources such as coal and nuclear power. The subsidies provided to renewable sources are about 100 times less, thus making it seem much more expensive than, in fact, it really is, compared to the sources mentioned above. A serious case of behind-the-scenes smoke and mirrors.

Will Your Utility Bill Get Cheaper?

The short answer is a resounding “No”. As the supply of traditional fossil fuels decreases, so the cost of accessing those fuels increases, and those increased costs are then passed on to you, the situation will only get worse, and the costs will continue to escalate. Since 1970, utility rates have increased annually an average of 5.5%. Not only that, but paying your utility bill will never provide you with any equity. it’s more like a variable interest rate loan that can never be paid off and whose rate continually increases.

Hidden Costs Of Traditional Electricity Sources

The federal subsidies make traditional electricity sources look like a great deal. But, what about the intangible costs, or the costs not readily apparent? Did you know that the cost of these subsidies is covered by the income the government garners from your income taxes? Other hidden costs include increased pollution, damage to the environment and natural habitats, increased health care costs due to the effects of the increased pollution, etc.

If all these hidden costs are taken into account, renewable energy begins to look like a much more attractive proposition.

States To The Rescue

More and more states are answering the call to increase their presence in the solar energy field by providing substantial rebates for new installations. California is one of the leading lights in this area, with the California Solar Initiative providing rebates depending on the expected performance of any new solar installation. These rebates go a long way to leveling the energy playing field.

Hidden Benefits Of Solar Energy

While certain benefits of installing a solar electric system may be obvious (reduced, or eliminated, electricity bill; environmental benefits), others may not be so obvious. For example, did you know that having a solar electric system installed on your home may well increase the equity value of that home? This alone could cover the cost of installing a system, should you ever need to sell your home.

Even though awareness of the problems caused by carbon emissions and the dangers presented by global warming is increasing, adoption of solar and renewable energies is taking place slower than is desirable. The cause is generally attributed to myths and misinformation regarding renewable energy and solar energy in particular, the primary myth being that solar is far too expensive. Hopefully, the facts presented here will lay that myth to rest and open the door to wider acceptance of and investment in solar and renewable energy.…

Residential Solar Electric – Free Electricity For Your Home

Residential Solar Electric – Free Electricity For Your Home

To aid us to trim current energy needs, we can tap into the suns power in many applications. There are a few systems on the marketplace that will turn the suns heat into use able energy to supply hot water for a household.

These systems only involve a few small solar panels on the roof to furnish you with unlimited free hot water. Additional systems provides light for your homes interior using average natural sunlight which lowers your monthly bill and cuts out the demand for artificial luminance. Further methods to get costless heat for your homes interior is to have your place face due south and the emplacement of big windows allowing the sun to enter and heat the homes walls and floors.

The warm walls and floors will then relinquish heat in the evenings allowing a moderate temperature all year using only sunlight. Electrical solar energy has gained wide spread interest in modern years as an substitute source of free strength from the sun. This technology takes the light the sun provides and converts it into useful electricity for your domicile. For decades this technology has been use able but only lately has it been so widely accepted. The reasoning is obvious which is much better pricing and much improved efficiency.

Today these systems furnish a frugal way for the medium householder to create their own electrical solar energy from the sun and never have to submit another electricity bill again. The electrical solar energy systems chief factor is the solar panel. This solar panel is responsible for converting the suns luminance into electricity through a accumulation of solar cells located within the solar panels. The process of photovoltaics is the precept that these solar cells use that does the changeover, and over the years have made huge improvements. The photovoltaic outcome occurs when particular materials are placed in straight sunlight and yield a small electrical current as a result.

Even while this current may be extremely small, when a number of these cells are connected together in a solar panel, they can generate quite a bit of ability. The electrical requirements of most homes demand to have a number of solar panels containing these solar cells to yield them the electrical yield that is needed. These solar panels render DC electricity which is a component of the transition process.

Our homes work on AC current and the DC current from the solar panels is converted to AC current that may be used by us through the usage of an inverter. An inverter will substitute the solar panels current through to the homes electrical system for everyday use. The inverter will also send some of this power to a battery bank if you resolve to place one to charge these batteries for employ in the evenings when the sun has set and the solar panels are inactive. The battery banks that had been recharged from the electric solar energy system will render electricity in the evenings.

Every one of these parts are in all the residential solar electric systems and connected together to yield you all the energy your home can practice.

The bulk of the parts needed to render this costless energy can be installed by yourself. A qualified electrician should be hired to make all the final connections to meet local electrical codes and safety requirements. When your new residential solar electric method is installed you can render all the power you demand for years with really little care.…

Green Living – How Solar Panels Work And The Benefits Of Using Them

Green Living – How Solar Panels Work And The Benefits Of Using Them

I was staring at approximately the 50 houses as I was walking up my street in sunny Southern California and it struck me, “Why wouldn’t every house have solar panels? And if they did, we would have an abundance of energy and be free of the tyranny that exists around our dependence of oil.

Once you understand how solar energy is harnessed, you will find it very easy to see the benefits of green solar energy. Thermal and Light are the two types of green solar energy that exist.

1) Thermal energy is considered “passive”. An example would be capturing solar energy from the materials and design of the building when it was constructed. Specifically, the building would be built to integrate south facing windows with materials that would capture and retain the heat, hence reducing your energy needs because your structure is more efficient. Another example would be using the thermal energy produced by the sun to heat water for solar hot water systems.

2) Light energy is considered “active” and is produced immediately from the rays of the sun. The sun’s light and radiation is captured by solar panels to create electricity.

The current motivation and popular reason to use green solar energy today is for saving money. The relatively higher initial costs of these systems generally pay for themselves over a few years.

The newly installed systems provide supplemental electricity and often all of the electricity for your home. Business are taking advantage of this as well.

One of the most cost effective ways to capitalize on these benefits is building your own solar panels. In conjunction with the many government rebate programs, refunds and net metering (where you sell your unused electricity back to the power company) make it very advantageous and directly reduce the cost of implementing a green solar energy system. One of the best advantages is green solar energy systems require little to no maintenance after they are installed.

The real benefit and probably most important of utilizing green solar energy is the significantly reduced impact on the environment. Climate changes have been scientifically linked to the increased storms, polar ice caps melting and other issues caused by global warming. Green energy provides a clean energy alternative as it creates little pollution and reduces our dependence on fossil fuels.

Solar systems can be used by homes and businesses alike. If going solar cannot meet all of your energy needs, it can certainly reduce them. Utilizing green solar energy can save you money, but its greatest benefit is to the environment and our future.

Look out for my next article discussing alternative green energy sources including sun, wind and water and how you can save money by harnessing them.…

Free, Clean Energy With DIY Solar Panels

Do you dread opening your power bill? Are you one of the millions of people who’ve seen a steady increase in both the amount and cost of power used? The fact of the matter is that most homeowners have seen a consistent upward trend in power usage, thanks both to the increased number of appliances and gadgets in the average home as well as the ever-expensive cost of power itself. It’s enough to make a person swear off electronics and join a commune! Before you pack your bags and throw away your gadgets, there is some good news: Energy experts have long predicted the growing cost of power as well as its increasing scarcity, which is why they have emphasized the use of renewable resources to combat this syndrome. There’s a growing list of energy alternatives, but the most practical and accessible option is DIY solar energy.

Solar panels offer a simple, effective, and clean method of providing energy at a marginal cost. By utilizing photovoltaic cells, solar panels capture the heat of sunlight and turn it into real, usable power that is channeled into your home’s power system, reducing your dependence on traditional energy sources. There are a multitude of companies that manufacture DIY solar panel installation kits that make it fast and easy to install your own solar power generator, and you don’t have to be a genius to make it work. The typical solar power kit comes with the panel itself already manufactured, so all that is required of you is to simply install it onto your roof. Once in place, the DIY solar panel begins capturing energy from the sun immediately and converting it into power that can be used to run your iPod, television, and even refrigerator! The minor drawback of solar power is that it is dependent on sunlight, so if you live in an area that is prone to cloudiness and rain, you can expect a somewhat lessened amount of generated power, but don’t let that discourage you from solar panels. Even the smallest amount of clean energy helps reduce pollution and your power bill, and small steps really add up over time.

Whether you’re a clean energy enthusiast or just a regular Joe looking to cut back on energy usage, DIY solar energy is a realistic solution to your needs. As the cost of manufacturing solar power decreases and becomes more readily available, it’s more likely than ever that entire cities and states will switch over to the clean, free energy available from the sun. Be ahead of the crowd, and install your solar panel today!…
