I´ll show you shortly How Solar Energy Works so you see how the panels are connected to batteries, inverters and other important gear.

Solar cells, also called photovoltaic (PV) cells, allow you to work with the sun’s power to generate electricity with no noise, greenhouse gasses, fragile structures or fossil fuels. That permits you to dramatically decrease your carbon footprint and protect yourselves from annual utility rate increases.

BATTERIES

Solar PV installations goes in two ways: including battery and direct. In the case of battery systems the sun charges the battery on clear days (it´s not the direct warmth of the sun that makes a PV system efficient, it´s the intensity of the solar radiation. Normal battery systems for country homes and off-grid installations make somewhat less power (18 kilowatt hours) than the normal home power usage (20 to 30 kilowatt hours). Battery installations are however not merely fitting for off-grid solar power installations, they as well function as storage in regular grid connected houses for when the sun doesn´t shine.

To see How Solar Energy Works, you must know that it is not possible to merely push your solar installation into your homes’ wiring as the voltage output generated by your solar installation change wildly due to instable solar intensity during the day. This would blow away your house equipment since it´s very vulnerable to electricity changes. You ought to have specific gear such as batteries, inverters and transfer switches. Batteries work both as storage and as a barrier to absorb the fluctuating electricity output of the panels and shield the inverter.

In an urban area you are connected to the electricity grid (direct system) and a battery is not considered necessary (though can come in useful in case of electricity lacks for example). You will be able to use the electricity generated by the sun to power your dishwasher through the grid connection.

A battery is needed to store the power that the solar panel generates when the sun is shining and to make that energy available to your electrical devices at your house when it´s asked for (that is during nighttime and when the sun doesn´t shine). When you are not capable to give the produced electricity to the grid (which is the case for diy solar installations due to the technical requirements of your utility company), you have to use a battery-bank. That is exactly the way how solar works.

Though a PV panel provides energy when the sun is shining, there are other things next to the batteries, needed to conduct, control, convert and distribute the generated energy.

Which of these things you would need, depends on how you would work with your DIY Solar Panel. You would however certainly need an inverter that converts your stored Direct Current (DC) electricity from your batteries to alternating current (AC) that your electrical devises at home need.

INVERTERS

A bank of batteries can generally give you 12volts, 24volts, or 36volts, whilst grid electricity is normally at 240volts. The inverter changes the 24volts into 240volts needed for the house electric equipment. A ‘true sine wave’ inverter carries a harmonious stream of energy to your devices, just similar to the stream which comes from the grid. Matching the flow like it comes from the grid shields your sensitive appliances like your PC´s, a fridge or appliances that need a dimmer, or a speed control. This you need to be aware of to realize How a Solar Panel Works.

Now you understand How Solar Energy Works, are you ready to decide to decrease your electricity bill and that you will not have to pay the constantly increasing electricity rates, than you can go to the local solar contractor or build the system by yourself.

Osbone 1 was the first moveable computer that was launched in the market throughout 1981. Control program monitor, an operating system in 1970s was as well utilized in Osbone 1 which was before the moment when MS-Dos wiped it out totally at the time when IBM PC was brought in in 1981.

This machine being portable, professionals were able to carry their data and vital information along with them. Though, Osbone 1 did not support any batteries which were its biggest drawbacks. Hence, they were required to be plugged directly to an AC power. Comparing it to contemporary times you may appreciate what an inconvenience that was.

Further, Kypro 11 was invented to be a perfect model rather than being a rival of Osbone 1. Kypro 11 came with a software bundle that had double density floppy drives in contrary to Osbone 1. Also, Kypro 11 had twice the characteristics both in screen and its storage capacity as compared to Osbone 1. Then Bondwell 2 was brought in due to the decline of control program monitor. It was launched to the market in 1985. But as standard computer platform began to lean towards the IBM PC thus in 1983 Compaq was launched.

Epson PX-4, NEC PC 8410A, PX-8 and NEC PC-8500 were the other portable computers that were introduced later. Though, there were no standard hard disks or floppy in any of these four units. In 2005 the UN General together with Nicholas Negroponte hence revealed the draft prototype of notebook computers.

One of the major characteristics of modern day life is our dependence on electronic tools which we rely upon on a daily basis for a multitude of routine and mundane tasks. Ranging cleaning to cooking, entertainment to communication, electronic tools are here to stay and are an integral part of any average person’s lifestyle.

Our faithful friends and partners, the downfall with many of these tools is that they are at the risk of malfunction and breakdown and this can vary from being merely inconvenient, to downright costly (in particular, in the specific context of a business.)

Given that all machines and electronic tools are nothing more than a compilation of different parts which work together to achieve a common purpose, the failure of even a single component (regardless of how trivial the fault, or how petty the role actually done ) is enough to be the end for the machine in question. All electronic gadgets require fuel in the guise of power and this will be derived either from the mains power supply or from a battery source.

The major weakness of any electronic machine is that it is only ever as useful and creative as long as it is provided with power, and this should not be so much of an issue. If they actually lasted for a semi decent period of time! To add further risk of injury, the current generation of electronic batteries are not actually rechargeable (whether this is due to a basic design flaw or a cynical tendency to force consumers to buy them more frequently is uncertain.)

The very foundation of capitalism is progress and novelty, i.e. the continual striving for the perfection of current technology in a bid to maximize efficiency and by extension then, benefits as well and the latest development in the energy market has been the growth of the solar battery chargers. The remarkable aspect of these chargers is that they go a significant way to eliminating the various flaws and drawbacks most commonly associated with the ordinary forms of electronic batteries.

Many consumers are a little uncertain as to the precise manner in which the solar battery chargers operate, and eventually, fail to appreciate or understand the awesome potential that they possess. The manner in which they work is the same as a factory : they accumulate the energy provided by the sun, and then store the power in order for it to be transformed into electrical power. This means that the owner of the solar charger will have an enduring power supply that will only cost them the initial amount- and nothing more.

As the cost of conventional sources of energy continues to rise solar power is now more than ever a clean and viable source of energy for the home and for business. Billions of dollars have been spent in the United States over the past couple of decades in promoting and developing this technology. In this article we look at some of the benefits of solar energy.

It is estimated that the cost of the equipment to power a home with solar energy is 90 per cent cheaper than it was in the 1970s. And with energy bills rising rapidly it is now an increasingly attractive source of electricity.

In most cases, using solar energy to provide electricity for a home involves installing special solar photovoltaic cells in the roof of your home. It is true that the initial investment is quite expensive but this money should be recouped in savings on electricity bills over time and significant savings can be made in the long-term.

In sunnier areas solar power can meet and even exceed an average home’s electricity needs at certain times of the day. Excess electricity can be stored in batteries or in certain areas it can even be sold back to electricity supply companies.

Here are some of the main benefits of solar energy:

* It’s cheap – Once you make the initial investment to have solar technology installed in your home it is a free source of energy. Once it has paid for itself you can make make significant savings on your energy bills. You may even qualify for government incentives to help cover the cost. What is more it will add significantly to the value of your home. Green homes are becoming ever more popular in today’s environmentally aware climate so this investment will increase your home’s value and make it easier to sell if you ever move on.

* It’s clean – Solar is one of the cleanest and environmentally friendly sources of energy out there. If you want to do your bit to combat climate change solar energy is the way to go.

* It’s easy – Solar energy systems require very little maintenance. Once the system is installed you will have a constant source of energy and you won’t have to worry about adding extra fuel, paying bills and the other chores associated with conventional sources of energy.

* It’s consistent – If you use solar energy you do not have to worry about power failures. Even if your traditional source of electricity fails you will still have a back-up. In addition, if you live in a remote area that does not have easy access to centralized sources of electricity solar is an excellent alternative.

* It’s neat – Even if you live in a heavily populated area installing solar panels should be no problem. Since they slot easily into the roof of your home there is no need for them to take up precious garden space. Also, while the panels themselves are costly, they are very easy and quick to install.

* It’s wire free – There are a number of stand alone solar-powered appliances available today that eliminate the need for wiring. For example, you can install solar powered garden lights that you simply place in your garden that run of the sun’s energy. These even have light sensors so they switch off and on automatically depending on the light.

The use of photovoltaic cells in the home can be quite expensive. However, it is not the only way to make use of the sun’s energy. In colder regions homes are increasingly being designed to make the best use of the sun’s energy to provide warmth. This involves sensible design of houses by using methods such as having large glass windows on the south side of the home which will help warm the home during the winter. The home will need to be protected from too much sun in the summer so trees can be used for this.

Another option is to use the sun to provide hot water from the home. This method simply involves using thin water pipes, painted black, and running them through a ‘greenhouse like’ box that is exposed to the sun on the outside of the home. In warmer areas this can provide hot running water throughout the home for free.

Solar energy isn’t for everybody. Where you live will determine whether or not it is the right choice for you. If solar panels are not viable for you, or you are unsure if you are ready to take the plunge, you should still consider buying solar appliances when possible. There are any number of solar appliances available today including video cameras, watches, radios, fountains and much more. These all eliminate the need for batteries and/or wiring.

Use of solar energy is becoming more and more popular every day. The price of electricity is rising and the best alternative that we have today is using solar energy. We all know that global warming is on an everyday rise today. The main reason for this being burning of fossil fuels like coal,which in turn is being used to produce electricity,so if we want our future to be safe, this is the time we step forward and start using solar technology

NEED FOR ELECTRICAL POWER

Arguments that have constantly supported that electricity is of utmost importance and needs to remain are:

1) Need for light and power after it becomes dark
2) Need for appliances to work so that the food we eat remains edible.

We would be greatly interrupted in our daily routine if we did not have power or electricity for large portion of day. Not being able to use electricity for either work or entertainment would be a great hamper on life as we know it.

VARIETY OF SOLAR ENERGY PRODUCTS

The main reason that many people don’t use solar energy is because they are not aware of what all it has to offer. Thsi being stated that they are not aware of what all products are available that can be used with the help of solar energy for an average home. In fact, you can install solar energy systems that range from small portable systems for your vacation home to large permanent solar energy systems that are built right into your home as either a standalone system or a grid system. It is this wide-ranging versatility coupled with the fact that it is a renewable easily available power source that makes it such a great thing.

You can start out small with individual systems such as solar water heater,solar shower, solar lighting, solar fans. That is not all these days we also have solar radios,cookers,purification system. Solar energy is far more useful as it can be used to recharge your batteries and you can also power up every single appliance in your house with the help of the right solar system. It is just a matter of determining where you want to utilize it.

Solar energy can be used in your garden or home. By using it in multiple places around the household you can cut your power bills significantly. There are a multitude of uses for solar energy around the household. It can be used to recharge your batteries, phone and other small appliances. Once you discover solar energy for the home, you will realize that you can power up virtually any electrical appliance or machine with the right solar energy system and supplies.

CONCLUSION

After reading the above article you can quickly start to see where and how utilizing solar energy would benefit you,your pocketbook and your children. Just remember that todays saving could lead to a bright and healthy future. So invest in solar system kits and you can enjoy every aspect of electricity with the help of solar energy, you can work in well lit conditions, you will save your money and you will protect the environment. You can enjoy solar energy for the house by working it in your life gradually.

The Future of Solar PV (Photovoltaic) Energy
1. The Problem
2. The Solution
3. The Results
4. The Benefits
5. An Investment in the Future

1. The Problem:

Traditional sources of electrical power generation are running out as production will peak in the next decade but demand will continue to rise. Energy prices will continue to rise at a higher rate as well as the number of outages during peak hours. There is the obvious problem of the pollution we are causing to our environment.

From my perspective, the world’s energy needs vary greatly; there is no clear single solution to the problem of supplying the world’s energy.

All forms of energy production have issues associated with them, i. e. -

1. Coal – Pollution/Strip Mining
2. Natural Gas – Cost and Lack of Infrastructure
3. Hydro – Limited Availability/Environmental Concerns
4. Wind – Limited Site and Resource Availability
5. Solar PV – Higher Cost
6. Nuclear – Waste disposal

2. The Solution:

Solar PV (Photovoltaic) systems effectively deliver three to five hours of peak power per day at roughly 10 Watts per square foot. Not one square inch of new land would be required to site PV. Theoretically, there are adequate residential, commercial, Government rooftops, and parking structures in California to power a substantial percentage of our State’s electrical needs from solar.

In Southern California, solar produces a net energy gain in approximately three years. This means that within three years, PV systems begin producing more energy than the energy spent in producing the system and its raw materials. Best of all, the energy produced cost zero emissions.
At today’s prices, a typical solar system costs approximately $8.00/watt, installed and has an operating life in excess of 25 years. For all intents and purposes, maintenance and operating costs are minimal. Now there are systems available for rent. Companies such as Citizenre at www.jointhesolution.com/rethink-solar allow you to create solar power of a unit that is installed, maintained and monitored by them. You merely pay the monthly rental fee for you clean electricity which is the same price as you pay the electric company for you electricity. Also they allow you to lock in a rate now for up to 25 years so you are paying the same price throughout the entire contract.
3. The Results:

Solar energy increases the diversity of power and adds stability to a fossil fuel favored energy structure, while reducing greenhouse gas emissions.
4. The Benefits:
– Solar can be quickly deployed at the point of use, reducing the need for additional transmission and distribution infrastructure, and cost thereof.

– Solar operates most efficiently at mid day, when grid demand is at its peak. By decreasing the strain during peak hours, the longevity of existing power plants and infrastructure is extended, lowering further the cost of energy production.

– By deploying solar over time the cumulative effect of the installed base is impressive. Given its 25-year life, within 10 to 20 years, a respectable portion of California’s energy could be supplied by solar.

– Once installed, the cost is fixed. In comparison to traditional sources of energy, the fuel cost is nonexistent, and operational costs are limited. A solar system’s cost is amortized over its life, there are no rate hikes due to fuel or operating cost increases.
5. An Investment in the Future:

There are some negatives. Presently, solar costs more than traditional energy generation. Its efficient use is limited to daylight hours unless storage is employed. Admittedly, the solar industry today is not large enough to address all of our needs. The solar industry does not have the financial influence to compete with existing utilities, which typically oppose PV, within political circles. (Industry revenues globally represent only 3.0B/year). Globally, the industry has experienced an annual growth rate in excess of 18% in over a decade. This rate of growth is equivalent to that of semiconductor, telecommunications and computer industries.

Clearly, there is no easy solution to California’s energy problem. No doubt, a variety of technologies and tools are needed to ensure California’s energy independence and security.
The Solar Industry Needs Your Support
For those interested in promoting a clean, safe and environmentally friendly source of energy, I urge you to write your representatives in the State and Federal Government. Make it clear you vote for representatives who support current legislation aimed at advancing the deployment of solar energy, such as the net metering law which allows the solar producer to feed surplus power onto the grid, causing the meter to spin backward, lowering the electric bill. Tax credits and deployment subsidies provide the revenues necessary to support research and development of more efficient solar systems.

Remember, in the 1970′s the State of California enacted emission standards that surpassed the rest of the nation. The argument against these standards was the cost of such improvements. Almost 30 years later, the impact is in the air and reflected in the increased fuel economy of the vehicles we drive.

Solar energy is part of the solution and is a key to America’s long-term energy supply. After all, fossil fuels have a long history of issues with respect to stability of supply and cost.
The Outlook of Solar Power is Bright!
1. Solar will sustain its torrid growth, as costs continue to fall. The solar market has grown at ~40% per annum in recent years, and there are many reasons to think that it will sustain, if not exceed, that clip in 2008. Solar panel prices have followed a predictable experience curve since the 1970’s, with prices dropping by 20% with each doubling of manufacturing capacity. As the silicon-dominated industry moves to thinner and higher-efficiency wafers, increases manufacturing scale, improves wafer and cell processing technologies, sees polysilicon prices return to rational levels, and migrates production to lower-cost countries –- costs will continue to drive towards parity with grid rates, and solar will become increasingly more attractive. Companies have developed creative PPA (power-purchase agreement) financing models to reduce or eliminate upfront installation costs, which will make solar more accessible for a wider range of corporate and residential customers. The election year should also see more state subsidy support for solar and a renewal of the federal tax credit, which will further bolster growth.
2. Emerging startups that benefit from the polysilicon supply shortage will face increased pressure, as the poly-Si crunch begins to ease. Solar veterans can debate the timing endlessly, but many expect additional poly-Si supply to come online by late 2008. Startups that tout silicon-independent solar solutions, like concentrators and thin film (CIGS, a-Si, CdTe, etc.), will face pressure to come to market more quickly, as their cost/supply advantages erode with greater availability of poly-Si and a retreat from spot-pricing. E.g., none of the CIGS thin-film startups, which have collectively received hundreds of millions in investment in recent years, managed to reach mass commercialization this past year as many had projected. They will continue to be under pressure to reach market before the window of opportunity closes.
3. Entrepreneurs will increasingly look beyond cell and module production. As the technology-heavy areas of cell and module production get crowded, more and more entrepreneurs look to startup opportunities in the downstream balance-of-systems part of the value chain. This area has seen less attention to date, yet makes up ~50% of the total installed cost. Novel packaging techniques, distributed inverter / MPP tracking / power management technologies, systems monitoring solutions, streamlining of the installation process, and creative solar financing models — entrepreneurs increasingly recognize the ripe opportunity in this part of the solar business, and 2008 should see heightened startup activity in this area.
4. China and India will begin to emerge as strong domestic markets for solar. With a 500 MW coal-fired plant going up in China every week, the growth of greenhouse gas emissions has reached dizzying levels. China already “boasts” 16 of the 20 most polluted cities in the world, with hundreds of thousands a year dying prematurely from such pollution. Many experts expect that the government will spend tens of billions of dollars in the next 5-10 years –- a significant portion going to solar -– to reach the mandate of 15% from renewables by 2020. In India, where the energy shortfall has reached 15% and domestic coal reserves will run out in ~50 years, the government is actively pursuing incentive policies and feed-in tariffs to help drive the use of solar and other renewables. 2008 should see further policy refinement in both countries, which will spur increased domestic adoption of solar.

Few people doubt solar energy’s potential, but many wonder when it will be reached. “In the long term, solar may well play an important role,” Karg says. “I personally expect a contribution of 10 to 20% of the global electricity production, mainly in the form of grid-connected systems.” However, he does not foresee that happening within the next 20 years.
Nevada Solar One
The sun sits high over the Nevada desert in the Eldorado Valley, gleaming off the upside down rows of mirrored parabolic trough collectors at the Nevada Solar One power plant.
At 64 megawatts (MW) of generation capacity, Nevada Solar One is the largest CSP plant to be built in 15 years. While the plant won’t come online until April, its construction marks the revival of an industry that has seen almost no market growth in over a decade.

The plant was developed by Acciona Energy and Solargenix Energy — two companies that have worked hard behind the scenes to get the CSP industry up and running again.

The plant uses parabolic trough collectors to generate electricity. The mirrored troughs face the sky and direct sunlight to a large metal and glass receiver in the middle of the trough that holds circulating oil. The oil travels to heat exchangers, which heat water and create steam to run a turbine. Parabolic troughs are one of three commercialized CSP technologies.

Further down the row of parabolic troughs, Plant Manager Bob Cable admires the impressive devices before him.

“I’ve been working with this technology for the last decade,” Cable says. “I’ve seen some impressive gains in technological advancement, and now we’re seeing more broad acceptance of the technology as the market becomes more attractive.”

Indeed, after roughly a decade of little growth for the industry, CSP is coming back strong. And it’s not just parabolic trough collectors that are experiencing a boom. Power towers, which use heliostats to focus solar energy on a central receiver to produce steam, and dish systems, which use reflectors to power a generator at the dish’s focus point, are making great strides in technological capabilities, lower costs and market acceptance.

But according to Thomas Rueckert, Program Manager for CSP Management at the U.S. Department of Energy, parabolic troughs are the most advanced.

“Because of the track record [the parabolic trough industry] had in southern California with the 354 megawatts (MW) operating — and actually improving in performance — I think you’re seeing the financial institutions more willing to embrace trough technology because it’s proven and the risks are less,” said Rueckert.

Rueckert was referring to the 354 MW of parabolic trough collectors installed in California’s Mojave Desert between 1984 and 1990. Those plants are still operating today, currently producing energy at around $0.12-$0.14/ per kilowatt-hour (kWh) and proving the technology can provide clean, reliable energy to the grid.

The Nevada Solar One plant will produce electricity at around $0.15-$0.17/kWh. While those costs are double what area residents pay for electricity, Nevada Solar One will sell energy to two utilities through a power purchase agreement (PPA). The PPA will ensure a fixed cost for the electricity over a long period, making the solar power economical down the line.

Now that global investment in CSP is increasing, technology costs are decreasing and renewable portfolio standards (RPS) in the U.S. are requiring more solar generation, project costs for all CSP technologies should come down significantly in the coming years, said DOE’s Rueckert.

“All of those things have really opened the door,” he said. “And it’s interesting that all three technologies are pushing forward, which was kind of unexpected.”

Back at Nevada Solar One, Acciona Solar’s Cohen stands before the group of reporters and members of the solar industry who have come to witness the rebirth of CSP.

“The potential is huge. It was difficult to get the attention of the financial institutions in the U.S., but right now we have their attention. We get a lot of people asking us, ‘how can we develop this technology?’”

Dr. Alex Marker, Research Fellow for Schott North America, Inc., stands to the side of Cohen, nodding his head. Schott is certainly feeling the positive impact of increased CSP development. To meet the demand for its glass receivers, the company brought a new receiver manufacturing facility online in Germany last summer and is developing another facility in Spain that will come online in early 2008.

“I think [the market] is going to grow drastically,” says Marker, looking over at the receivers in the troughs. “We’re happy to be a part of this new development.”

Now that financial institutions are noticing CSP, companies like Acciona and Solargenix will be able to tap into the vast resource potential in the Southwestern U.S.

According to figures from DOE’s Solar Lab, 20,000 MW of CSP capacity could come online in the U.S. by 2020 with the proper investment and technological capabilities. Rueckert seemed optimistic that a large amount of those resources will be tapped.

“When this plant comes online next month, it’s going to be a great success,” he said. “The market is exploding and things are really taking off.”
