Solar Power

Solar power is another ancient energy source that has benefited from developments in modern technology. The oldest forms of solar power used sunlight as a direct source of heat energy. One simple device used to reflect solar energy, the parabolic mirror (a dish with a concave reflective surface), can be traced to 3rd century BC Greek mathematician and inventor Archimedes. In 1882 the Frenchman Abel Pifre demonstrated that a parabolic mirror could reflect and focus the sun’s rays onto a water boiler, producing sufficient steam power to operate a small printing press. Several modern solar power stations use an array of such reflectors, which move to track the sun, focusing solar energy onto a central boiler.

A relatively new form of solar power, the photovoltaic cell, converts sunlight directly into electricity. The photovoltaic cell is a semiconductor device, closely related to a computer chip, that relies on the photoelectric effect. Discovered by French scientist Antoine Edmund Becquerel in 1839, the photoelectric effect describes how sunlight can create an electric current by generating electrically charged particles.

Developed by scientists at Bell Laboratories in 1954, modern solar cells are generally made of crystalline silicon, a semimetallic element. Photovoltaic cells were first developed in the 1960s as a power source for orbiting spacecraft in the U.S. space program. They are now widely used as a power source for satellites, remote communications systems, traffic signs, and consumer electronic devices such as pocket calculators and watches. Advancing technology has driven production costs down by 80 percent in the past 20 years, and solar electricity is beginning to emerge as a potential competitor to fossil fuels.

In one new application, several companies have integrated solar cells into a new generation of roofing shingles, tiles, and window glass, allowing homes and office buildings to generate their own electricity. In the United States, a home equipped with this technology costs roughly $20,000 more than an average, traditionally powered home. A significant market for this technology is emerging in Japan, due to a system of government supports introduced in 1995. By the end of 1998, Japan is expected to have at least 25,000 solar-powered homes-enough to electrify a city of 100,000 people.

Both the United States and the European Union (EU) announced solar-roof programs in 1997. These programs, which are still being formulated, are partnerships with state and local governments as well as the private sector. They are intended to provide tax incentives, low-cost financing, and other assistance for those who want to use solar power.

The main impediment to increased reliance on solar power is cost. Most experts believe the cost of solar cells must fall by 50 to 75 percent to be fully competitive with coal-fired electricity. Automated manufacturing, larger factories, and more efficient cells may deliver major cost reductions in the near future. But for now, solar cells are used primarily in remote locations, where access to other forms of power is sharply constrained.

One breakthrough that promises to significantly reduce costs is the development of a new generation of thin-film solar cells. These cells are less than one one-hundredth the thickness of conventional solar cells. They do not need to be sliced or rigidly encased, eliminating a costly process, and they can be made into large, flexible sheets ideal for integration into building materials. Thin-film solar cells also use less raw material, further reducing costs.

3 Top Reasons You Should Not Go For A Solar Panel Installation

These are my top three reasons why you should not make your own solar power installation. This is supposed to give you some objective information to inform you of why a solar panel installation is not necessarily a good thing. So here are the facts:

Reason 1: A solar power installation costs a lot and only pays for itself after a long time

If you are going to purchase a solar panel installation, you are looking to spend upwards to tens of thousands of dollars. Even with the best sun exposure and if you were selling the electricity to your power company, it will take you tens of years to repay your investment.

Many people get attracted to the idea of getting a free source of electricity, which would even provide them with electricity to sell. They, however, remain ignorant of the investment, which would be required to make this possible. Even worse, sometimes they just purchase the solar power system thinking that it would repay itself quickly and only then find out that it could take up to 20-30 years. This is definitely a trap you would like to stay out of.

Reson 2: The efficiency of your solar power installation is highly dependent on your solar exposure

This reason is kind of obvious, but let us look deeper into it. Before you purchase your solar system you are supposed to look at the potential for making solar power in your area. This depends on the amount of sun exposure you get there. So let us say you get a high amount of solar exposure. What could go wrong then?

Well, let us just say that solar exposure is a variable. In other words, when talking about a long-term investment, which a solar power system is, you could imagine how a variable such as solar exposure could change. Natural conditions have shown the potential to change, so it would not be unimaginable to have a previously very sunny area gradually start getting less solar exposure. This, in turn, could make a profitable solar power system rather unprofitable.

Reason 3: The efficiency of your solar power system is also dependent on the surroundings

This last reason might sound negligible, but in fact it is the biggest possible turn-off. Two major things pop up in mind in this regard. They are pollution and surrounding buildings.

First, pollution has the potential to shorten the life of your solar panels as if you live in an area with high levels of pollution, your system’s life will be adversely affected. Second, a solar power system project, once again, is a project done with a long-term perspective. We already said that we could not predict solar exposure for the long term. Even more, we can not predict that your building would not be surrounded by taller buildings, which would reduce your solar exposure.

These were the top three reasons why solar power systems are not a good choice. Now that you think about it, you might not want to make a solar power installation anymore. But do not despair. The purpose of this article is not to discourage you from making your solar power system. Exactly the opposite – solar power systems are great and if built with consideration and in a cost-efficient manner, they could bring a good return on investment.

Wine and Chocolate Create Solar Power

What do you get when you mix chocolate and wine? In the case of Clean Solar, Inc., you get solar. Silicon Valley Entrepreneur, Randy Zechman, is the founder of City Chocolate Fountains (the largest chocolate fountain rental company in the United States). Jeff Ritchey is a San Jose native and wine guru. He is a wine consultant for Pichetti Winery, San Saba winery, and has two of his own labeled wines. Together, they are the co-founders of Clean Solar, a Silicon Valley solar installer and integrator.

Randy Zechman will readily admit that he is a serial entrepreneur. Just over a year ago, with two successful businesses in his portfolio: City Chocolate Fountains and World 2 Do, Inc., Zechman was ready for a new challenge. Zechman and a friend of eight years, Jeff Ritchey, an award-winning winemaker, regularly attended a monthly Bay Area speaker series with a group of friends. After every speaker they would end up at a local restaurant debating the subject matter of that night’s speech, global warming and the health of the earth were often the center of those debates, which resulted in them seeing Al Gore speak at the State of the Valley conference in early 2007.

After seeing Al Gore speak on solutions for protecting our planet, Zechman began to research the solar power industry. Ritchey, while continuing to grow his label, Sensorium Wines, was also showing increased interest in the green movement, realizing that green technology was an ideal fit with his knowledge in geology, winemaking and construction.

Zechman knew that the scientific and construction skill set that Ritchey could bring to the table would be the perfect compliment to his business and marketing skills, which led him to approach Ritchey about starting a solar power company.

Zechman and Ritchey met weekly for 6 months, discussing the in and outs of the business and making sure that their ambitions would not get in the way of their friendship. “We had a heart to heart regarding our friendship versus business. We both believed we could manage both and that our friendship would not get in the way.” says Zechman.

“We’ve been friends for eight years and never thought about getting into business with each other, but this presented the right opportunity. With the market timing, our passion for doing something good, Randy’s sales and marketing experience and my technical and construction abilities, we figured it was a natural fit.” says Ritchey.

Clean Solar Inc. quickly became a reality and is now the Bay Area’s leading solar installation company. The fuel for their business growth is in the form of state rebates through the 10 year, $3.4 billion California Solar Initiative. While silicon is still in short supply, the rebates offer customers a chance to significantly lower the installation cost of a solar power system. Zechman and Ritchey are committed to staying ahead of the curve and being early adopters of new solar technology as it comes on line. “We want the Clean Solar team to stay abreast of the latest advancements in technology, maintain certifications, and educate ourselves in order to provide our customers with the knowledge they need as a solar owner.” says Zechman.

Home Solar Power Systems and Why They Are Neccessary

Home solar power systems are a trend that is certainly escalating each and every year that goes by. It needs to be realized that even though this pattern is extremely clear in the United States, various other nations around the world are doing exactly the same thing. Signs are that solar energy is definitely expanding in several parts of the planet on different continents.

Around the U.S. specifically solar energy has been used to power around 200,000 residential accommodations on a medium to large use basis. Also, more than 10,000 more homes in quite a few cities have solar power photovoltaic systems set up. This information comes from a customer survey carried out recently in the United States amongst homeowners regarding their using solar power.

The cost on the fitting by installers of new solar power systems is perhaps probably the most key elements in making use of solar power electricity. This is far a lot more the situation than any technical troubles involving unit installation and implementation.

However, homeowners need to not be discouraged from making use of solar power since after the initial payback period, you will discover apparent economic advantages being gained. The reason being the source of energy from solar electrical power reduces typical power bills substantially. The actual monetary calculation needs to become made state by state as parameters can vary.

Yet the fiscal appeal may well be enhanced even far more inside the sense that not merely is it possible to produce electric power for you, but you are able to also generate electrical energy to become sold back for the standard power production companies.

As a result, home solar power programs may be the generating process not only for saving you cash on your power bills, but also for generating cash by selling excess electrical power. How Cool Is That! This can have a substantial impact on the profitability of such a process and the way in which it might be utilized to lessen the payback time by a substantial amount.

The U.S. energy policy act of 2005 says that public utilities must make net metering attainable to buyers that call for it. This net metering is the term that pertains for the guidelines for buying the surplus form men and women making use of renewable energy. In numerous circumstances credits are given as opposed to cash for the surplus power produced. In either case the owner of the solar electric panels process comes out ahead.

State by state, restrictions for exactly how this procedure does apply for home solar power may perhaps differ, and also associated with the home’s solar energy generator plus the distribution grid. Thus make certain in each case.

The homeowners are generally eligible for tax rebates and incentives for your installation of solar power power programs. It truly is of course essential to check using the regulations which are enforced by individual states and local authorities about these credits.

In some instances these may possibly only be obtainable to commercial, industrial or non-profit institutions situated in buildings where such energy generation devices have been set up. In general though, it really is worth checking for these solar rebates, tax credits and other programs for employing renewable energy that a lot of states, as well as what the Federal government provides.

These rewards for property owners consist of things like bonds, deductions, grants, exemptions and loans which are furnished for your home solar power users.

Those who are thinking of using home solar power systems are asked to perform a little reading through and analysis before they go ahead and take steps to change to this mode of use. It usually is far better to be well informed and to use the available information sources.

Pros & Cons Of Solar Energy

Every day, households around the world are using up the planet’s resources for energy. If this continues, these energy sources will be depleted quickly -unless alternative renewable energy sources are utilized.

One of the energy sources that modern technology has recently put to good use is solar energy. Solar energy isn’t anything new, but new technology advancements have placed solar power more into the mainstream, and it may one day be one of our primary sources of power. –

Advantages of Solar Energy

Since solar energy comes directly from the sun, it is not only renewable, but also accessible in any part of the world. As long as the proper equipment is utilized, unlimited amounts of solar power can be collected and put to good use.

Solar power is also one of the cleanest forms of energy, since it creates no pollution, and produces no greenhouse gases or waste products. For residential uses, the use of solar power minimizes negative impacts on the surrounding environment, making it a safer alternative to wind or hydro power.

Not only is solar energy non-pollutant, in terms of gases, but it also causes zero noise pollution – since there are no moving parts in any of the devices which are used to capture the sunlight. Due to the fact that no moving parts are used, maintenance costs are low as well – only occasional cleaning and periodic battery replacements are needed. Most manufacturers of solar panels provide twenty-year warranties for their equipment, guaranteeing long-life operation.

Solar panels placed on rooftops also double as a heat absorbers, slightly cooling the top area of the house which is directly below the roof.

Disadvantages of Solar Energy

The most obvious drawback of solar energy is its sole dependence on the sun. Once the weather becomes cloudy, or night strikes, energy collection comes to a halt. However, recent advancements of technology now allow the generated power to be stored in special batteries which provide roughly enough electricity to last a night.

This is why solar-powered devices, including flashlights, are gaining in popularity and are proving to be efficient energy savers. Solar panels can also be expensive, because of the materials that are used to create them. And even when these materials are taken out of the equation, the entire process, considering the other devices involved, can be a bit costly. This includes portable devices that utilize solar energy. But most of the cost involved is in the initial purchase and installation of a solar power system – not running costs.

Fortunately, there are some people who sell damaged solar cells, which are much cheaper. These damaged solar cells can be used to build fully functional solar panels, using the application of simple do-it-yourself techniques. Although in every part of the world, there is at least some point in time when the sun shines, it is also true that direct sunlight is needed in order to make the most of the sun’s energy – and to generate the highest amounts of power. This significantly restricts the placement of solar panels. And some areas in the world may receive little benefit, due to lesser sunlight.

What’s the Bottom Line?

More research and development continues to be invested into this growing technology, and that’s a good sign for the future of our households – as solar power may one day be used more frequently than other energy sources. Of course, solar energy isn’t perfect, but it makes a great complimentary addition to other energy forms.
