Solar Roof Shingles Reduce Your Electric Bill

solar roof shingles

Solar power is a renewable resource which can never get exhausted, no matter how much you use it. Using it to full effect can help you save a lot of money. Solar roof shingles are the latest modified form of solar panels which are being used at homes to get the maximum out of sun’s energy. Roof shingles powered by solar energy are still a very new technology to most people, but many are already using them because of their long term benefits.

What are solar roof shingles?

These are basic looking shingles which can generate electricity by converting the sun rays into electrical energy. Solar roof shingles are installed on the roof, tilted towards the direction of the sun. Once you connect them with home appliances, you will notice a drastic reduction of your electricity bills. Each shingle has the ability to produce electricity between 17 to 50 watts. That doesn't sound much but adds up quickly when multiplied by a whole square footage of the roof. Shingles come with special support structures that can withstand wind speeds equal to 80 mph.
The technical name used for solar roof shingles by scientists is Building-Integrated Photovoltaic (BIVP)

How to install solar roof shingles?

Solar roof shingles can be installed faster than solar panels. The initial cost of this technology is estimated around $20,000. Both, front and back side of the roof can be covered with solar shingles because the systems doesn't require direct sunlight but produce electricity as long as there’s daylight, even on cloudy days.

They are installed like asphalt tiles. These are put in layered form on the roof with 5 inches of the shingle exposed to sun. After the installation, wiring is connected to home electrical appliances by electrician or expert in solar energy systems. You can then feed the electricity back into your local power grid or go off grid entirely.

Long Term Benefits of Solar roof shingles

Although these solar roof shingles are expensive initially in long term perspective, they can prove to be the cheapest way to generate electricity.

  • The cost of maintenance and monetizing is very economical.
  • They can be used in very remote places on earth.
  • People living near equator can use it to its full potential as they receive sun’s UV rays all throughout the year.
  • The quantity of power generated by such system is enough to fulfill home needs.
  • They are easily replaceable, flexible and a green way to produce electricity, which is the main reason behind the invention of the technology.

Solar Power Your Business

Have you wondered what all the "buzz" is about using solar energy to provide power for your home or business? Perhaps you have thought that the technology is too expensive or otherwise not worth the investment. Its time to change that thinking. More and more often, property owners are installing solar panels on the roofs of buildings, to harness energy from the sun to be converted into electricity. Power bills for the buildings on which the panels are installed drop to next to nothing as a result. Each panel costs between $150 and $1,500, depending on the brand, vendor and wattage. Currently, solar cells cost approximately $4.30 per watt. For a 50-watt solar panel, the total cost is about $215. The number and square footage of panels required to power a business is determined by calculating watt-hours of electricity typically used over a 24-hour period. Not surprisingly, the expense of the initial installation is the biggest hurdle.
Sun Edison and MMA Renewables specialize in providing financing and solar power installations for commercial customers. In addition, expect to see more tax incentives for renewable energy sources in the future. Additional information about current incentives and subsidies can be found at The Solar Guide.

In Bend, Oregon, one local newspaper has installed solar panels on the roof of its building. The Source Weekly is located near the downtown center in a historic building. Known as an off-beat, quirky news organization, perhaps it is not surprising that it is also forward-thinking with respect to solar energy. Solar panels installed on the rooftop are proudly visible to passers-by which, is both innovative marketing and good, green sense. If a small business can successfully incorporate solar power into its business model, perhaps its time that larger organizations start to do the same.

Al Gore Speaks About Carbon-Free Renewable Energy

On July 17, 2008, former United States Vice-President and Nobel Peace Prize winner, Al Gore gave a compelling speech at Constitution Hall in Washington, D.C. about the urgent need to develop renewable energy sources within the next 10 years. He challenged Americans (and their leaders) to be "running on 100 percent zero-carbon electricity" in the coming decade. Among other things, Mr. Gore championed the fact that solar, wind and geothermal power is more affordable, while we have to face the reality of the climbing costs of coal and oil. A new advertising campaign, developed by The Alliance for Climate Protection, will encourage supporters of clean energy sources to advocate for new laws and policies that will result in the reduction of global warming. Currently, the United States is generating an abysmal 3% of its electricity from renewable sources like solar energy.
Gore talked about updating the electricity grid in the United States. Connection with areas rich in wind and solar energy would help the rest of the nation. He also talked highly of plug-in electric vehicles (PEHVs), which, if combined with a carbon tax could "increase the flexibility of our electricity grid." Gore's speech has been compared to the 1961 address of JFK to put a man on the moon within 10 years (which was accomplished ahead of schedule, by the way).
Later in the day, Mr. Gore answered questions on National Public Radio (NPR) regarding his monumental speech. Among many things that he discussed, Gore noted the fact that Germany has a strong solar energy policy and, as a result, the relatively small country has more solar panels installed than the total square footage in the United States.
Watch Al Gore's Speech here:



When asked about whether Gore would accept an invitation to be Vice-President once again, he laughed and stated that he had imposed his own term limits on the Vice-Presidency, which he served for 8 years under Bill Clinton. At this point in his life, the 60-year old Gore is much more interested in serving the cause of preventing further global warming than sitting in political office. I cannot think of a better person to lead this charge.

Mr. Gore noted that 10 years is the maximum amount of time we have to act before we will not have the ability to recover from environmental crisis. Tellingly, Gore also noted that a decade is just about the amount of time our political attention span would permit: "A political promise to do something 40 years from now is universally ignored because everyone knows that it's meaningless. "Ten years is about the maximum amount of time that we as a nation can hold a steady aim and hit our target."
Let's all hope that our attention span for reducing greenhouse emissions and our reliance on foreign oil supplies does not run out first.

Solar Panel Glass-A Window to the Future

There is another exciting development in technology news concerning solar energy! On July 10, 2008, researchers at the Massachusetts Institute of Technology (MIT) announced the development of "solar concentrators," which operate to take energy from sunlight that strikes a window and concentrate it at the edges of the pane, where solar cells would be located.
The effect of the new solar windows would be to increase efficiency of traditional solar panels by up to 100%. The new solar panel glass would be best suited for office buildings with large areas covered by windows. Similar to solar paint, special dyes that absorb light is "painted" onto a pane of glass. When UV light strikes the panes, solar energy then is pushed out to the edges and collected, where it can be harnessed on much smaller surface of solar cells.
The solar windows such as these would be a more cost-effective way of utilizing renewable solar energy, than larger, more expensive solar panels. The future will still have to wait, however. It will be about three years before solar panel glass will be available for installation and use.

New system will deliver about twice as much power(100% more!) than regular solar panels.

For more information, watch the following MIT video in which Mark Baldo discusses MIT's solar concentrator.

Solar Taxi on Tour

If you thought Solar Taxi was the name of a new rock group, think again. The Solar Taxi is a two-seater solar powered electric car that can go over 200 miles without recharging and can reach a maximum speed of 60 MPH. The car is powered by a five-meter solar trailer covered with six square meters of solar cells. Electricity is stored in a newly invented ZEBRA battery. It’s the brainchild of Swiss teacher, adventurer and environmentalist, Louis Palmer, whose dream is to drive this car around the world without using a single drop of gas or creating a single CO2 emission. His dream is coming true right now. The point, according to Palmer, is bigger than a personal challenge. He wants draw attention to the need for alternatives to fossil fuel and to demonstrate that there are solutions to global warming.

The Solar Taxi team started driving west from Europe last July and has now traveled more than 34,000 kilometers covering India, China, S. Korea, and Australia. At the moment they are cruising down the west coast of the United States—country number 28 so far—making stops at various UC campuses before heading east. They plan to be in Montreal by the end of September. The tour will finish at the World Climate Change Conference in Poznan, Poland on December 3rd. You can check out the route here. Stop by and say hello if you have a chance.

Promoting Plug-In Electric Cars

She is not even old enough to drive yet, but Liza Stoner from Minneapolis, MN is riding her bike to Washington, D.C. from her hometown to raise awareness about plug-in electric vehicles and electric hybrids (PEHVs). The 14-year old girl aspires to be an environmentalist when she grows up, and it appears that she is well on her way. Currently, Liza has completed more than half of the 1,585 mile "Ride for Renewal", riding 40-70 miles per day. She plans on delivering a petition to Congress on or about July 18, 2008 when she arrives at the Capitol. You can sign the petition here, which seeks governmental tax credits and other incentives for companies that produce electric cars. Talk about a breath of fresh air! I've already signed the petition - now its your turn.

Solar Power Can be Entertaining

Is your head starting to spin with all you've been hearing about solar power and alternative energy sources? Maybe you've been to the Santa Monica pier in California! A world-famous ferris wheel is powered by solar panels, and illuminated with LED lights, making it one of the premier attractions at the park.

The amusement park ride was first constructed in 1996 and was the first and only solar powered ferris wheel in the world. A new ferris wheel opened just in time for Memorial Day weekend in May 2008, at the cost of $1.5 million. The incorporation of 160,000 LED lights on the ride cuts energy consumption and costs for the park as a whole, while installed solar panels generate over 71,000 Kw hours of PV power. Use of solar power allows the 90-foot ride, and its 800 passengers per hour, to operate wholly on clean, renewable energy. Now that is something we can all smile about, while we go around and around on the benefits of solar energy.

Solar Powered Gate Opener

Looking to save on your energy bill? Who isn't? More and more these days, solar panels are being installed to use energy from the sun and convert it to electrical current. Living in a very "Green" city, Bend, Oregon, I have noticed a number of creative ways that homeowners and businesses are using new PV technology to power everything from traffic signals, school reader boards and gates. One property owner along a busy thoroughfare has gated his driveway to prevent trespassers who like to cut through a gravel shortcut to a nearby trail system. The gate is powered by a solar panel, which probably cost between $150 and $250 (including shipping). That's it! Companies such as Hoover Fence Company offer the solar panels for sale on their websites. Energy from the sun will power as many as 15 gate openings per day. You can even preview installation manuals on-line to determine how easy it is to get a solar powered gate up and running on your property.

Of course, not all gates are as rustic as some of these models. For luxury properties, you may wish to consider a $1500-$2000 gorgeous wrought iron solar energy operated gate. Amazing Gates is one company that manufacturers these beauties. Not only can you purchase solar powered gates directly online, but you may also view installation videos.
You'll be able enjoy significant savings on your power bill, and the next time there is a storm or power-outage in your area, you need not worry about getting through your solar-powered gate.

Still "on the fence" about whether to get a solar-powered gate opener? Let me tell you: the grass is definitely greener on this side.

GM Goes Green in A World-Wide Way

As if all the hoopla about GM’s new Chevy Volt electric car weren’t enough, the Detroit based automaker has gone a step further in repenting for its sinful, SUV producing past. As part of its new green image, GM announced on July 8th that it will install the largest solar roof in the world on its car assembly plant located in Zaragoza, Spain. The project will cover 2 million square feet of rooftop, and will use approximately 85,000 solar panels. On completion the project should generate 15.1 million kilowatts of power per year. The company is not just talking green talk, it is putting its resources into walking the green walk. It's a brave move as there is little margin for error.

GM’s announcement comes amid whispers of bankruptcy and at a time when GM stock is lower in price than it has been in 40 years. What will happen, both to the project and to GM, is anybody’s guess, but clearly, one of America’s biggest corporations has totally reversed course and realized that the future of the country and of the world lies in finding viable alternatives to fossil fuel. It’s good to see an American automaker waking up to reality. Come home to America, GM. All is forgiven. I can’t wait to test drive a Volt.

GM Europe President Carl-Peter Forster discusses this new project.

Solar Power Comes Crashing Down

The sky is falling! Will getting hit in the head with a large battery knock some sense into people? Or will they continue to ignore the solar energy that falls from the sky everyday? The video Hail - The Return of the Sun was created by Solon AG, a German based manufacturer of solar cells and PV power panels as a part of their campaign to raise awareness on the subject of solar power.

A Green Light for Solar Panels

Solar energy is free and plentiful. And it doesn't have to be a bright sunny day in order to harness the power of the sun to electrify our lives. If we can use solar power to energize our laptops and cell phones, even our homes, why not cut down on the energy costs associated with traffic management? PV solar panels can be installed on or near traffic signs to power flashing lights that alert drivers and pedestrians to conditions on the road. Northwest Power LLC, based in Colorado, produces Solar Traffic Signs that will work in cloudy coastal regions, as well as sunnier climes.
While out for a weekend run, I discovered one of these devices about 2 miles from my home. On the front of the sign is a cautionary blinking light, signaling a busy intersection ahead. The PV panel absorbs solar energy which is converted into electrical power; a battery is located at the base of the sign. Among the benefits including lower energy costs for the governmental agencies maintaining the signs, include the ability to avoid running power lines and/or trenching, as well as lower maintenance costs. The technology has spread to allow use of solar power to energize street lights, traffic lights and brighten road studs. Importantly, these traffic signals will continue to function in the event of a power failure when the need for safety alerts may be most critical. With all these positive features, government agencies should be getting the green light to install these reliable, energy-efficient signals.

NOT Working on Solar Panel Powered Electric Cars Says Dyson-Just a Digital Motor

The news was announced a couple of weeks ago in an article in Britain’s respected Independent newspaper. England’s most famous inventor, Sir James Dyson, is developing an electric car powered by solar panels and capable of real speed and distance. Web Pundits and bloggers all over the world picked up on it right away. What an appealing idea: The man who liberated the housewife from icky vacuum cleaner bags is going to free us all from the tyranny of the internal combustion engine. The news spread across the internet with the speed of a Paris Hilton video.

And then the Dyson spin machine turned on and the retractions started. Bloggers and web-pundits who had heralded the news last week have taken it all back in the past few days. The company’s Public Information office explained that Sir James, in his interview with the Independent, was talking about their cutting edge digital vacuum cleaner motor and just observed that it could possibly be used to power an electric car. The journalists misunderstood.(yeah, sure) Listen to the audio clip on Gas2.0.com.

I, for one, don’t believe a word of it. Journalists, particularly in big print media, are big on fact-checking and getting quotes right. The reclusive Dyson just wants the media off his back is what I think. Who can blame him? I wouldn’t want the pressure either if I were in his shoes. But I bet the work goes on, and I’d put my money on Dyson any day to come up with just what the world needs—a fast electric car powered by solar roof panels.

From Dyson Vacuum Cleaners to Solar Panels Powered Cars

I filled up my car with gas this morning and had one of those déjà vu moments. Waiting my turn in a line of ten cars, I was transported back thirty years to the gas lines of the last energy crisis. This morning I saw the same grim desperation in the faces of motorists jockeying for position at the pump. I felt a little desperate myself as I shelled out a king’s ransom for half a tank of gas. Here we go again, I thought. The squeeze is on.

At least one man I have faith in is working on the problem. Britain’s most famous inventor, Sir James Dyson, of Dyson vacuum cleaner fame, is now turning his considerable talents to the development of a solar powered electric car by using solar panels. Traditionally, electric cars, although quiet and pollution-free have been slow—around 30mph—due to the fact that batteries powerful enough to produce speed, and compact enough to not take up all the space in the car, could not be developed. Automakers from Detroit to Tokyo are working on the problem, but most are thinking in terms of batteries that recharge by being plugged in to an electrical outlet of some sort.

Once again, inventor Dyson is thinking outside the box. Reportedly, he and his research group are working on a lightweight electric vehicle whose battery will be charged by solar panels, installed on the roof of the car and on the roof of the garage where the car is parked. Admittedly. there are some kinks to be worked out, but according to Dyson, his lightweight, fast, solar powered vehicle will be road-ready within a few years, and able to travel hundreds of miles between charges.

I don’t know about you, but after paying for my gas this morning, I can hardly wait.

Solar Energy and the Feasibility Study. What Does It Mean?

The United States has lagged behind western European nations in getting solar energy projects off the ground for the last two decades, but now, with the price of oil sky high and global warming being taken seriously, venture capital is pouring in. Florida, California, and the desert Southwest lead the way in both operational and planned solar power plants to provide cheap renewable energy to hundreds of thousands of residential and commercial customers. Michigan’s sagging economy is being boosted by green entrepreneurs who are turning out solar panels and roof tiles using the skills of unemployed Detroit auto workers. The future of solar looks bright.

But wait. Here comes the government. Late last month, The Feds put a moratorium on new applications for solar power plants planned on government land pending a massive environmental impact study. The Bureau of Land Management which administers more than 100 million acres in the western states of Arizona, California, Colorado, Nevada, New Mexico and Utah where most large scale solar development is concentrated, is concerned about potential effects of solar plants on nature and wildlife. The study will take up to two years to complete and will address potential effects on vegetation, water use, and animal life. Environmentalists and solar energy companies are worried that the study could effectively cripple a nascent industry, at least temporarily.

Oddly enough, there is no slowdown in the construction of new coal burning plants, especially those using the new clean coal technology. Worldwide at least one new coal powered plant goes into operation every week. In addition, lifting the 30 year ban on offshore drilling in US coastal waters is even now being considered by the American Congress. This would certainly have a negative impact on water and wildlife not to mention the economies of places like the Jersey Shore. But nobody seems to want to do a feasibility study on that. Kind of makes you wonder what’s really going on, doesn’t it?

Greenhouse Gases, Climate Change, Ozone Layer, Solar Power

In last months, I've been noticing more and more articles, how the increased solar activity is the cause of global warming and climate changes. By their words, we should blame the solar power. What an utter nonsense! Luckily, it had been defeated by many very extensive scientific studies, including NASA. Climate changes and global warming in this very moment are entirely caused by human activity on earth.

In this very short video Vermont state climatologist Lesley-Ann Dupigny-Giroux explains one of the major planetary components of climate change: greenhouse gases. The ozone layer protects us from UV radiation, but with increased greenhouse gases in the atmosphere, the 'greenhouse effect' is largely increased, warming and deflecting more solar radiation back to the earth.
Her experiment shows, how even on a very dark or snowing day the earth is still receiving UV radiation.



We simply have no other choice, than to switch to free solar power and other renewable energy sources, if we want to defeat our own extreme pollution on all levels of society, worldwide.

Solar photovoltaic roofs (solar shingles-tiles, solar panels) are one of the solutions of how to truly become power independent and totally environmentally sustainable.

Solar Power could save Antarctica and its beauties

Processes of Climate changes could be addressed properly, if only we decide to switch from fossil fuels, which generates green house gases, to renewable energy sources.
Endless solar power, wind, geothermal and hydrogen economy in the second phase of this urgent project are so very viable and easy to perform with our current technological knowledge.

It is going to cost much less than $1 billion to achieve 50% efficiency rate of solar cells, yet the government is struggling to find the financial resources to finance the project and covers all researches under the secret military program.

Only the war in Iraq is going to cost much more than $3000 billion!
And thousands of casualties.
And the record oil prices.
And catastrophic financial credit crisis.

When our leaders are going to accept FREE, ENDLESS and CLEAN solar power, wind, geothermal and hydrogen economy?
When our leaders are going to realize that the life on Earth is dying, because of our extensive pollution?

When we are going to use the vast surface of our empty roofs to produce free electricity and heat? Solar shingles, solar panels, solar heat collectors, etc. Wind farms. Geothermal power plants.
We only need to use them on the national scale to become truly energy independent and environmentally sustainable - friendly.

Antarctica is dying. North pole is dying. Ice is melting, because of our pollution.
Let us stop all these deadly dangerous destruction and let us use renewable energy sources.

Solar Power Works in Every Day Life (San Jose, California)

Let us look around a bit to see how some solar photovoltaic products, which allow you clean and sustainable way of living, work in every day life.

Low cost and hassle free solar power panels.





Renewable energy is affordable and hassle free. It is our Present and our Future.


p.s.
The future of Solar Power Roof is bright.

Solar Power is not Corrupted as our Top Political Elite

Why do our Top Politicians still refuse to admit, that there is no future for our civilization without a total change of Energy and Pollution policy?

Why our top Leaders do not want to fully support Endless Solar Power and other Renewable Energy Sources, which are not harmful to our environment?

Why are we still spending hundreds of $billions for Oil, Coal and Deadly Dangerous Highly Radioactive Nuclear Material?


Because of the catastrophic level of CORRUPTION and LOBBYING among the highest leadership. Because of the immense Power of Money of Global Corporations.

How long it is going to take to finally realize that only the Endless, Clean and Free Solar Power and other renewable energy sources could save our existence on Earth?

The Future of Solar Power Technologies is Very Bright, after US election

Scientist Arthur Nozik, of the National Renewable Energy Lab, Golden, Colorado is researching a phenomenon called Quantum Dots, which could revolutionary improve efficiency rates of solar cells.
New solar power photovoltaic technologies developed on the principle of Quantum dots could dramatically lower the price of solar cells by using only a fraction of previously used expensive semiconductors.



We could also add some additional positive facts to already mentioned much lower production price and much higher efficiency rate:
- a massive production of solar cells and their products (solar panels, solar shingles-tiles) could additionaly lower the cost of solar photovoltaics devices
- tax rebates
- other financial incentives

Sadly, all this could happen only after the Presidential election, because of the very strong opposition from US government and the White House.


The future of solar powered roofs is very bright, under the new President.
