Solar generator is a kind of generator which produces electricity through the direct shining of sun upon solar panels, and the electricity can charge battery, which supplies power for energy-saving lamp, recorder, television, DVD, satellite receiver and other products.

Solar generator can be divided into several parts, solar battery components, charging and discharging controller, inverter, test instruments, monitor and other electrical devices. It has protective functions, for example, when solar battery component is over charging or over discharging, it has function of protecting itself, solar generator can produce direct current which is 12V and alternative current which is 220V, and it has small occupation of space, easy for taking and using.

Now we’d like to introduce the advantage of solar generator, the advantages are as followed.

1, it supplies power independently, and is not subjected to environment. It doesn’t need fuel and mechanical transmission component, it can be produced at a short period, so the scale can be at your will.

2, compared with fire generator and nuclear generator, solar generator doesn’t cause environment pollution, and it has aesthetical appearance, low fault, and long life.

3, it is easy for dismantling and installing, and can work on the move, so it cost lower in installation cost. Because it can be combined with building, we don’t have to bury electric wire.

4, it is widely used in all kinds of electric components, and is suitable for those families which are short of electricity, it can be used on electric component and lighting which is at countryside, hill, island, express way and other remote area.

5, it is eternal, as long as the sun exists, so we can invest money in studying it, but use the achievement forever.

6, the solar generating system can be listed form big ones to small ones. We can have middle power station which can produce 1000000KW, also generator group which can supply electricity for one family. It is incomparable.

The solar resource of China is abundant, so the potential development of solar resource is very broad.

America’s eyesores are becoming the hot places to install renewable energy for electric power generation. The land is cheap, often abandoned but properly zoned. They’re usually close to necessary infrastructure such as power lines and roads, and no other developers are rushing to erect anything on them. The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) is evaluating sites for renewable energy potential on behalf of the EPA.

Brownfields could be former industrial sites abandoned when the owners went bankrupt. There might have been paint or fuel spills there, but the exact source of contamination may be unknown. However, superfund sites usually have a responsible party identified. Some brownfields are ready for redevelopment, but others need a lot of work first.

Photographing the sky for its solar potential
Salasovich and other traveling NREL engineers start with a device called a SunEye, which has a fish-eye lens to photograph the sky above the landfill. “We point it south and take a photo,” he says. “It puts out a spherical graph and shows where the shade will be by what time of day and what time of year.” An algorithm built into the device can detect differences between the sky and a tree.

If a site has wind potential, the engineers install a meteorological tower with instruments to read wind speed and direction, according to Joseph Roberts, an engineer with the National Wind Technology Center at NREL. After 12 months of measurements, they can find an average speed and see how it compares with data from nearby airports. Crew members also check the distance to the nearest roads and transmission lines, evaluating the sites’ potential for generating renewable energy and making it work economically.

NREL Engineers select potential plots from the EPA’s list of superfund and brownfield sites, as well as those identified by the Resource Conservation and Recovery Act (RCRA). In some cases, the renewable energy apparatus in construction is powering the ongoing clean-up efforts at the sites. In other cases, the wind turbine, solar array, or hydro power is sending power to nearby cities. This is most feasible when the site is close enough to transmission wires to tie into the grid. There are about 11,000 sites in the U.S. with some past or current environmental contamination problem that may hold potential for renewable energy, according to Gail Mosey, senior energy analyst in the Strategic Energy Analysis Center. She says it’s a great opportunity to reuse land for power generation without help from fossil fuels.

Erecting devices without disturbing the contamination
Some sites, particularly superfund sites, are so contaminated with toxic chemicals and heavy metals that the earth should not be disturbed. However, Mosey explains, “There are a lot of others that can endure a slight intrusion. There are workable solutions for installing renewable energy on the surface or outside the contaminated area.” For example, solar arrays fit comfortably on top of the two feet of dirt and liner that typically cover a condemned landfill.
There are even wind turbines (supported by surface-mounted concrete footing) that can generate energy without burrowing into the muck of a superfund site. “These are places where you wouldn’t necessarily want to put a housing development, pour a foundation, or have people plant backyard gardens,” Mosey says, “but they are excellent sites for renewable energy.”

PHOENIX–(BUSINESS WIRE)–The National Renewable Energy Laboratory today released an initial study assessing the operational impacts and economics of increased contributions from wind and solar energy producers on the power grid. The Western Wind and Solar Integration Study examines the benefits and challenges of integrating enough wind and solar energy capacity into the grid to produce 35 percent of its electricity by 2017. The study finds that this target is technically feasible and does not necessitate extensive additional infrastructure, but does require key changes to current operational practice. The results offer a first look at the issue of adding significant amount of variable renewable energy in the West and will help utilities across the region plan how to ramp up their production of renewable energy as they incorporate more wind and solar energy plants into the power grid.

“If key changes can be made to standard operating procedures, our research shows that large amounts of wind and solar can be incorporated onto the grid without a lot of backup generation,” said Dr. Debra Lew, NREL project manager for the study. “When you coordinate the operations between utilities across a large geographic area, you decrease the effect of the variability of wind and solar energy sources, mitigating the unpredictability of Mother Nature.”

The study focuses on the operational impacts of wind, photovoltaics, and concentrating solar power on the power system operated by the WestConnect group of utilities in the mountain and southwest states. WestConnect is a group of transmission providers, which includes Arizona Public Service, El Paso Electric Co., NV Energy, Public Service of New Mexico, Salt River Project, Tri-State Generation and Transmission Cooperative, Tucson Electric Power, Western Area Power Administration, and Xcel Energy. Though wind and solar output vary over time, the technical analysis performed in this study shows that it is operationally possible to accommodate 30 percent wind and 5 percent solar energy penetration. To accomplish such an increase, utilities will have to substantially increase their coordination of operations over wider geographic areas and schedule their generation deliveries, or sales, on a more frequent basis. Currently generators provide a schedule for a specific amount of power they will provide in the next hour. More frequent scheduling would allow generators to adjust that amount of power based on changes in system conditions such as increases or decreases in wind or solar generation.

The study also finds that if utilities generate 27 percent of their electricity from wind and solar energy across the Western Interconnection grid, it would lower carbon emissions by 25 to 45 percent. It would also decrease fuel and emissions costs by 40 percent, depending on the future price of natural gas.

Other key findings from the study include:

• Existing transmission capacity can be more fully utilized to reduce the amount of new transmission that needs to be built.
• To facilitate the integration of wind and solar energy, coordinating the operations of utilities can provide substantial savings by reducing the need for additional back-up generation, such as natural gas-burning plants.
• Use of wind and solar forecasts in utility operations to predict when and where it will be windy and sunny is essential for cost-effectively integrating these renewable energy sources.

The study was undertaken by a team of wind, solar and power systems experts across both the private and public sectors. The study complements the recently released Eastern Wind Integration and Transmission Study, which examines the feasibility of integrating up to 30 percent wind in the eastern states.

The report released today is an important first step in assessing the impact of solar and wind energy on the electrical grid. Under the American Recovery and Reinvestment Act, the Department of Energy is investing more than $26 million to further study the Western transmission interconnection, which will help states, utilities, and grid operators prepare for future growth in energy demand, renewable energy resources, and Smart Grid technologies.

A solar powered generator can be used to run all the electrical gadgets and lights in the house.  A solar powered generator is just like any other generator, but it makes use of the solar energy for power generation.

Advantages Of Solar Generators

Solar energy is a pure form of energy, since it uses the direct rays of the sun. Therefore, it is environmental friendly. There is no pollution with a solar powered generator. By using solar powered generators you are helping in keeping the environment pollution free.
The solar power generator can be recharged every day, by simply keeping it in the sunlight.

In case of power failure, you don’t have to worry about supply of natural gas or other energy utility as you can easily use your solar powered generator.

Low maintenance cost of the generator makes it an attractive option. Once installed properly it will last years with very little maintenance required.

Solar power is completely free. After you spend money on the initial installation costs, you don’t have to worry about additional costs associated. So, if you thinking of cost control, go for a solar powered generator.

Power generation is comparatively cheaper as compared to other types of generators.

You can use these generators to run essential equipment in your home or office.
Disadvantages Of Solar Generators

You can recharge the solar powered generator only in presence of sunlight. When the sky is too cloudy, or in case of bad weather, when it snows for long durations or when a hurricane or tornado strikes, you cannot recharge your solar powered generator.

You can charge the generator only during day time.

The costliest component of solar powered generators is the solar panels. If the panels get damaged, replacing them can be expensive.

With the country facing staggering unemployment rates and the price of food and gas continuing to rise many people are looking for relief. Americans have witnessed the bail-outs of huge financial institutions and seen the government’s recent stimulus plan fall on its face. As the government’s plans and programs continue to produce nothing but waste many Americans are taking matters into their own hands, they’re coming up with their own solutions to their economic problems.

When looking at where you can eliminate wasteful spending one doesn’t have to look much further than the electricity bill. Each month these statements are full of charges that appear to be a necessary evil in keeping the lights on and the refrigerator running. The truth is, there is a much more affordable alternative to writing a check to the electric company.

MySolarBackup has made it possible for Americans to live “off-the-grid” through a solar power generator that provides all the electricity necessary to keep a household running. By harnessing the power of the sun, a solar generator can effectively and efficiently produce continuous electricity for a home. The best part about the solar power generator is that the electricity produced is free, meaning the monthly bill is a thing of the past.

Eliminating the burden of a monthly electric bill not only saves money but pulls people away from the reliance on an aging grid system that is susceptible to natural disasters, blackouts, brownouts and other interruptions in service. This means that when electricity is cut you still have the power of the solar generator to keep your home running.

In the past many people relied on gas generators to step in when electricity was lost but these units can be unreliable, costly and extremely loud. A gas generator obviously relies on gas to keep it running, thus there is always an expense associated with it. The solar generator simply stores the energy of the sun and converts it to electricity whenever you need it, eliminating the need to store gas in case of an emergency. A solar generator also runs with absolutely no noise unlike the loud gas generators of the past.

Perhaps the most important benefit of the solar generator is its ability to instill a sense of self-reliance. By not relying on the government or some utility company to ensure things will run smoothly a solar generator owner will know they can take responsibility and meet their needs. For those who have taken notice of the direction in which the country is heading the benefits of a solar power generator is obvious. Secure your solar generator today and enjoy the peace of mind knowing that when the lights go out you’ll have yours on.

A solar generator can benefit the home in a variety of ways. Depending on the size, it can allow a homeowner and family to remain unaffected in the event of a power failure. It can also be used to simply cut the costs of daily energy use.

In very simplified terms, a solar generator works by converting solar energy into electrical energy. This energy can then be used to do such things as power lighting, heat water, and run the TV. The generator consists of solar panels (which must be placed where they will receive the most possible sunlight,) a deep cycle battery for continuous use, and an inverter.

The inverter is necessary to convert the DC power stored in the battery into AC power. Determining the appropriate strength of an inverter for a solar power system is a fairly simple task to accomplish. First, add up the wattages of all of the appliances the solar generator is intended to power. Then, purchase an inverter that is slightly more powerful.

Of course, if the generator is only going to be used to run DC appliances, there is no need for an inverter. A DC meter and DC input will suffice. It is also possible to buy a ready-made solar generator, one complete with all the necessary components.

Many solar generators are capable of lasting a lifetime. Most are easy to install and easy to use. They are often ideal for usage in remote locations such as a winter home in the desert or a cabin up in the woods.If you intent to buy solar generators,I recommend a good station, cheap and high quality:Made-in-china.com.

How to Make a Solar Power Generator ? Follow me:

1.Buy (or make) yourself a small solar panel. You should be able to get one rated at 12 volts or better (look for 16 volts) at an RV or marine supplies store .

2.Buy yourself a battery.Get any size deep cycle 12 volt lead/acid or gel battery. We recommend rechargeable batteries from these green companies: Greenbatteries Store and Batteries.com. You need the deep cycle battery for continuous use. The kind in your car is a cranking battery–just for starting an engine.

3. Get a battery box to put it in.This is good for covering up the exposed terminals in case there are children about If you going to install the system in a pump shed, cabin, or boat, skip this.

4. Buy a DC input.This is enough to power DC appliances, and there are many commercially available, like fans, one-pint water boilers, lights, hair dryers, baby bottle warmers, and vacuum cleaners. Many cassette players, answering machines, and other electrical appliances are DC already and with the right cable will run straight off the box.

5. But if you want to run AC appliances, you will have to invest in an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances.Count up the number of watts you’ll be using (e.g., a small color television(=60 watts) with a VCR(=22 watts), you’ll need 82 watts.

6. Use a drill to attach the meter and DC input to the top of the box.

7. Use insulated wire to attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Connect the solar panel to the battery in the same way.

8. Close the lid (I use a bungee cord to keep it tight). Put the solar panel in the sun. It takes 5-8 hours to charge a dead battery; 1-3 hours to top off a weak one. It will run radios, fans, and small wattage lights all night, or give you about 5 hours of continuous use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.

Options: A pop-up circuit breaker may be added between the positive treminal and the volt meter. Some of you will want an ampmeter as well. The panels I recommend have built-in bypass diodes, but I recommend charge controllers for people who have panels without diodes. Another option is a voltage regulator, which is not necessary for a system this small, but a larger system would require one.
