Alternative energy environmentally friendly are becoming more affordable all the time and solar cell phone chargers are among the least expensive.
One of the easiest ways to reduce energy consumption is to use a charger that uses renewable energy from the sun to recharge a cell phone. These units small light come in a variety of sizes and power to recharge a breeze.
An alternative energy technology has come a long way in past decade. Today, the cell phone solar chargers are small enough to fit on a keychain and can be connected to a phone or mobile device.
The units are priced from as little as U.S. $ 15 more than U.S. $ 100 USA. Smaller and less expensive units take longer to recharge a battery that is discharged disadvantages of technology.
It may take 10-12 hours to recharge a cell phone. Light solar is needed, which means phones need to be connected during the day are normally in use.
An alternative is to buy a second battery and keep you connected to a solar panel during the day. A second alternative would be to buy a larger unit, which produces more solar energy.
The problem the population is even higher, will only work when the sun is hitting the panels directly and can still take up to eight hours to recharge. Keep a second battery connected all day could work, but the panels still need direct sunlight for most cases to function effectively. With the sun's movement from side to side of the house all day, the only direct sunlight can reach the solar cell for hours at a time.
Some people choose to create your own solar cell phone charger individual cells. These units are much less expensive cell with a lower back under $ 15. However, electrical experience need to connect the solar cell with an energy storage battery or a converter to change the output DC power to AC output device mobile can be used for recharging.
There are three general issues for shippers. These are the panels of a pull, key chain and mesh panels in place vertical. Flip versions similar to a clamshell phone with solar cells located inside a plastic housing. Keychain versions are very small and offer no protection to collect the energy cells. The vertical model is the most expensive and often rises as a framework. All versions can be found online for purchase.
An alternative energy technology is growing by leaps and bounds. Eventually, all mobile devices can be recharged using the sun's rays, but until day comes, the current models give an idea of what will surely be common in the near future.

And lately, seemed willing to try almost anything to achieve it. Now DARPA, agency usually behind the Pentagon's more ideas out there are putting their money in a former power: solar wait. How PV cells produce electricity
These are the three things you must know before you start building your own solar power system. While solar energy is a renewable energy source, but of course also has its cons. Which will win? Discover below:
Pro Solar Energy Systems
Solar energy is completely renewable. Once created it, solar panels that generate electricity for free for decades. This is perfect if you are simply looking to supplement conventional energy sources, they become fully independent in its energy needs, or even sell electricity to the power company.
Solar energy is a fascinating concept. As is the sun, its solar panels that generate electricity. Certainly, these solar panels are a benefit a bit pricey, but once you are, you are just done. Therefore, it is simply a matter of time for the panels to pay any investment they made. Therefore, power systems solar should definitely be considered if you are looking to make their own electricity on a regular consistent for the next few years.
With to Solar Power Systems
Solar Power Systems to produce electricity, that's for sure. However, they are fairly expensive and depend on natural conditions. The Times has not come even when everyone can afford to buy solar panels and therefore can not really see them around your area so much.
Besides the cost installations of solar panels that easily goes to the tens of thousands of dollars, solar energy systems is highly dependent on natural conditions. In other words, if a solar energy system is not well planned and placed in a sunny area, it will be ineffective. In addition, natural conditions and can change a place that uses to get enough sunlight can be beaten by a period of days less clear, which in turn negatively affect sunlight and energy, can be done. For these reasons, solar power plants is not the best option for producing electricity.
Pro solar energy systems
Now that things are pending a thread with a pro and one against it, the argument has to decide what to do. And this argument comes from the fact that you could offset the price factor, with good planning care and build their own tables.
You can make your own solar panels through a guide to ask yourself. After you have been guided on how make your panels, it is not hard to do, and even a person who is so confident in electrical engineering facilities or work usually can. There are programs available that provide guidance to the construction process textual and visual step by step of their own solar panels. With this guidance, power systems Solar should definitely consider!
These were the three main things to know when considering whether to make your own solar power system. There were two advantages and against one, it seems that the argument for solar energy systems earn. Finally, the conclusion is that it can be profitable, with an installation of solar panels if you do it yourself with an appropriate step. You can find reviews of several guides on the address below.

Including batteries at night to power.
It is common that misconception that the sizing of solar energy system is based on the size of your home. In fact, the best way to determine this look at the bill electricity. Are you looking for the number of kilowatt hours (kWh), which uses your home each month. It would be better if you could look at a bill that eventually would have a bit of "story" about it, showing its use over a year so you can have a good idea of your average energy consumption per month. If you do not have an account to leave, you can make a list of charges, calculation and amount of courage it takes to generate electricity. http://www.altestore.com/store/calculators/load_calculator/ The next factor that comes into play is the location of your home. Each site on the planet has a "value of insulation." This is the value means "sun noon "your house every day. These are the two factors that determine the size and cost of a solar home system. The addition of batteries in a system of this size can be very expensive ($ 3,000 – $ 40,000 for batteries only) and require monthly maintenance. The estimated cost of these systems would between $ 10,000 and $ 50,000 depending on usage and solar resources. If you want to have a better idea of a system to feed their own home, call your information into a calculator line. http://www.altestore.com/store/calculators/off_grid_calculator/

Six simple steps to estimate the cost of a solar energy system
Six simple steps to estimate the cost of a solar power system
Energy Systems Solar is not cheap. However, it is important to compare them in the context of other improvement projects for the home. The buyers of homes and realtors view a solar photovoltaic or solar water heating system and a significant improvement on the value-added- “similar adding a deck or renovating your kitchen. Also, unlike a deck or kitchen remodel, including the gain on your energy bills.
Solar energy systems are often an injection of additional funds, as well: many government and public services through attractive financial offer from the United States the incentive to reduce initial capital costs associated with a solar energy system.
Here are some foolproof ways to estimate the cost of a solar photovoltaic or solar thermal and determine if a solar energy system makes sense for you. Let’s start with a photovoltaic Home (PV).
Step 1: Estimate the house electricity your needs
To begin, it is good to have a sense how much electricity it uses. You better point of comparison if you know how many kilowatt hours (kWh) used per day, per month, per year. Your bill for public services should include this information.
Of course, the electricity bill will also show their costs and many utilities include a graph showing how the monthly energy consumption / cost varies throughout the year. This will help you assess the highest energy consumption and how season.
Residential construction
If you are building a new house, you should estimate based application type of equipment will be installed and the Chamber of square feet. The pross call this “burden”.
To calculate the expected load, create a chart to record use watts for each device. Each unit – “if a water heater, lamp, computer, or in a refrigerator should have an identification plate showing its power. Or you can get information from the manufacturer’s website.
Some amps and voltage of the list only label to reach watts multiply the two together (amperage Watts = Voltage x). In another column, record the number of hours each device is intended to operate. After many hours and watts to estimate the watt-hours of use per day. As it is difficult to foresee all electric charges (can be a problem at all tedious exploration toothbrushes and a portable charger), you can add a multiplier of 1.5 sure.
Step 2: Predicting the Future
In 2005, average electricity prices Residential United States ranged from 6 to about 16 cents per kilowatt-hour depending on where they lived. The average retail electricity and trade have increased by about 30% since 1999 and the upward trend should continue, especially overhead costs for coal and hydropower to generate electricity and to increase. So think about your electricity needs of the house and the present and future costs by over another.
Step 3: How much sun do you get?
The Florida Solar Energy Center has conducted a study to examine how a system of 2 kW photovoltaic would if installed on a very efficient energy through the area Continental United States ( http://www.fsec.ucf.edu/en/publications/html/FSEC-PF- 380-04 /).
The study accounts for all factors affecting the performance of a photovoltaic system, such as the effect of temperature PV cell, the number of hours of peak sun in different regions, and the efficiency of inverter to convert the energy sunlight from DC to AC.
Since the study implies, solar photovoltaic systems work anywhere in the United States. Even in the North or in “rainy Seattle”, a photovoltaic system can pencil if designed and installed properly. In New York, or New Jersey, a one kilowatt system should produce about 1270 kilowatts of electricity per year, in Seattle, a system should kilowatt produce about 1200 kWh per year. In the Southwest, of course, these reports are much higher.
Solar contractors in your area can help determine the ideal size for your solar photovoltaic system.
Step 4: Size your system
In general, solar photovoltaic systems sized between 1 and 5 kilowatts are usually sufficient to meet the electricity needs of most households. One of the advantages of network systems attached that you can use solar PV to supplement or offset some of its electricity needs, so you can size your system based on your budget and always added to the system later if needed.
In addition, as a side note, here is a golden rule to remember to help you calculate the physical space of the PV system may need: square foot yields 10 watts. Thus, in full sun, one square foot of a conventional photovoltaic panel will produce 10 watts of power. A system of 1000 watts for example, may need 100 â € “200 square feet area, according to the type of modules used.
Step 5: Know your repayments
Many states, local jurisdictions discounts, tax credits and other incentives to landowners to installation of residential photovoltaic systems and solar domestic water. To see a complete database of incentives available for the visit of renewables http://www.dsireusa.org .
At the federal level, you can enjoy a tax credit of 30% (up to $ 2000) for the purchase of a residential solar system at least until December 31, 2008.
Step 6: Run the numbers
Although the cost of a solar photovoltaic depends on the size of system you want to install, the electricity tariff, the amount of kilowatt-hours expected to generate, and the State / Rebates or tax credits that might be available, the formulas for calculating the yields are substantially the same.
For those who appreciate have the forms, the use of those listed below to make a quick estimate the approximate amount of a photovoltaic system could cost you.

Of course, a more accurate assessment can be done by a professional. Working with a contractor solar energy for size and the price system right for you. As with any major purchase, do not hesitate to ask several offers from different contractors.
Much suppliers of solar energy will provide a complete estimate. Useful information to know includes:
– Total cost for the operating system (cost Work for the design and installation costs and equipment)
– Team (Mark and model)
WARRANTY INFORMATION –
– The permit fees, if
– Taxes, if
– Federal tax credits
– State or local funds tax reductions or jurisdiction
Utility Refunds –
– Expected renewable energy certificates or credits Net metering
– Operation and maintenance cost estimates
– Projected savings
Solar Thermal (also called Solar water heaters)
Solar thermal systems capture the sun’s energy to heat water and are one of the systems the most viable renewable energy. Are used to heat hot water tanks and / or heating system. A system of solar pool heating Another type of solar thermal system designed to heat a pool or spa.
Usually, it is worthwhile to study the feasibility Economic installing a solar water heater If you have an electric water heater with utility rates of at least 5 cents per kilowatt hour and tax credits or discounts available. (It may even be worth changing a gas water heater if your costs are at least $ 8/million BTU).
The formulas for calculating the cost of a water heater plots are similar to the estimated cost for installation photovoltaic solar energy. Many solar energy professionals can help determine which system is best suited for you.
Heat your pool with solar energy
Although some provinces offer financial incentives to use energy Solar heated pool or spa, in general, using solar energy to heat your pool is a “manifesto” in a return on investment view.
The electricity used to heat a pool during the swimming season often amounts to the same amount of energy that households without-pools consume over one-year. The combination of a solar power system to produce heat for indoor with solar energy to conserve heat generated more heat can maximize the efficiency and extend your swimming season.
Most installers recommend a collection of solar energy used to heat a pool is a size of about half of square meters surface of the pool. The solar panels last 10 € “20 years and come with a guarantee of 10 years.
How long it takes to achieve balance in the cost of your solar system Power Pool depends where you live. In California or other parts of the Southwest, will have a balance in one to three years, but places like “north” as Canada, a system of solar pool heating pencils on a longer time period.

List some good reasons that I want a solar power plant near his home. This is for a school project for a list of some good answers.
I would like a solar power plant for my house. I have no problem with these things, nor do I complain about a wind farm. "Charcoal now (about 5 km from me) pollutes every day. This is the burning of" clean " the plan, but traders seem to have found a way to hide their pollution. I can see the yellow mist being emitted from the plume of steam from cooling towers (But not the steam is supposed to be) on sunny days. I told the EPA about this place, but nothing was done. Grift and I think that bribery. Finally, wind and solar plants clean and efficient when feeding operation and requires no registration or mining.

The efficiency of the solar panel would replace coal?
A friend sent me an article that a company called Fraunhofer produce solar panels can achieve 41.1% efficiency. Now taking into account the fact that solar energy is not sent to work at night or during storms and very low during the winter what% think it would be necessary to establish a "majority" of our energy needs as a nation? Typos * * Now, taking into account the fact that solar energy "not" work during storms or at night and very low during the winter, what% do you think would be necessary establish a "majority" of our energy needs as a nation?
I'm with g.aidono. The efficiency of the commission is not the problem is cost. The photovoltaic panels create efficiency hovering around 14% now – when you see the numbers as high as 41%, a cell that is exotic, and not a glass-resistant metal frame and suitable for home use. But even at 14%, if the cost of $ 2 per watt, which would cost a winner in most households USA. Even with four U.S. dollars / Watt is a winner today in some places, such as providing the latest, very expensive kWh someone's account. If you panels is U.S. $ 1 watt, even without subsidies, people would be clamoring to connect the panels – for many, in fact, that could threaten the stability network, and new architectures would be necessary.
