Solar chargers are becoming very popular, but they are still new technology for most users. What should I know?
John has discussed the issue in general, and gives some tips to ensure you get the most from your solar charger.
Portable solar chargers come in many forms.
They range from mobile phone size with a single solar cell and to accept a plug for the charger cable with large portable folding solar panels, as a closeNotebook.
Some mobile phone manufacturers have toyed with the idea of integrating a solar system in the back of a mobile phone to enable solar energy to recharge, in addition to the normal charger, but realistically, that is not likely for economic reasons, because the phones phones use materials that eventually become obsolete, or simply out of fashion. He can dispose of another component. We have already caused significant environmental damage caused by irresponsibleDischarge of electronic equipment and should not be that add Tally.
This idea is the same fate as the TV / VCR (which also remembers that?) Much better to use a solar cell has the ability to separate the universal charge are bound to fail. The solar charger can then consider providing more personal devices. But, who knows, maybe I'm wrong! we may soon see, notebooks and PDAs with built-in solar panels!
Back to our main argument, charging that use the sun to generate electricitythat is used is stored in a battery, if necessary, a very useful and environmentally friendly alternative to the AC-powered. You can, for example, if you are camping, without the need for long extension agreements or noise generators!
Some portable solar charger and solar panels can be connected directly to a device that requires electricity to be connected, for example, the Soldius solar chargers have voltage regulator with MPPT (Maximum Power Point Tracking) charge integrated electronicsHandy efficient. This is a stylish portable solar charger with a single socket for the charging cable and a selection of adapter tips that connect to accept a cell phone or other devices.
Soldius can not say the device is a small and compact, but the lack of an internal battery, it can store energy for later use than other solar chargers, so it's actually better, a mini-solar generator with a voltage regulator integrated. TrueEnvironmentalists see this as an advantage, because the batteries are one of the worst offenders of environmental contamination by heavy metals. In fact, eco-advocates would like to hear that most of the solar chargers are environmentally friendly Li-ion batteries. Lithium-ion cells are environmentally friendly because they do not use heavy metals.
We must distinguish between the portable solar charger and solar panels.
A solar charger can save a unit capable of solar energy for later use, becauseinternal battery to store charge. The solar panels are portable units of one or more solar panels, and sometimes attacked solar regulators, such as solar panels made Ecopia folding.
A useful feature of most solar chargers is the ability to increase the internal battery by means other than solar energy, such as USB-connected computer or power of a 12-volt car accessories outlet, if not the immediate solar power available. The supporters could see the greenthis as a betrayal of "negative energy brown" sector, but that should not be so, you can run your laptop with solar energy and battery of a vehicle is recharged while driving and usually has the energy surplus to sell.
Not all solar charger can fully charge your phone will be.
Why? because the solar charger on another battery to recharge the solar batteries and these are usually not large enough to offer a full charge.
A typicalSolar battery has a capacity of 1000mAh and is a typical cell phone battery 750mAh.
Now you might think, a 1000mAh battery should fully charge the battery 750mAh, after all its 25% larger.
Not so. As the phone battery charged, is expanding the internal resistance and voltage of the solar charger can not be easily overcome this internal resistance when the phone battery has reached a certain state of charge.
Voltage (V) is the electric pressure, the same current flow(I) multiplied by the resistance (R) V = IR
. The internal resistance of the solar charger drops its load and then decreases the voltage, but the contrary is happening in the phone's battery as it is, its internal resistance is increased to the point raised, if it is higher than the solar system is charged with battery voltage As current flows in it no more and no longer loaded. The best solar charger to help you make intelligent electronicmost from the charger, but at the end of the day, you can not cheat physics and the only way to improve this situation, the solar charger should be increased.
For this reason, most solar charge controllers, such as battery voltage changes have increased the load so that the battery is fully charged.
Always choose one of the largest solar battery charger.
Therefore, when choosing a watch solar charger solar battery capacitycorresponds to the view in milli-ampere-hours, for example 2000mAh (2000 milli-amp hours) thousands of milli-amp or an amplifier. In terms of battery capacity is 1 A of current for two hours, 100 milliamps for 20 hours, 200 milliamps for 10 hours, etc. are available. before going up. Well, this is not entirely true, because the battery voltage will drop about 20% capacity and the battery may sound flat at this point, and this is one reason for charging a batteryanother battery is not good as a constant power supply. Use solar charger Li-Ion (Lithium). Ion batteries are the new type of light, low battery and have advantages over conventional Ni Cads and the old lead-cells, are lighter and can do more, before being discharged back office and, especially, are respectful of ' environment.
Always choose a solar charger with the largest solar panels
Once you choose your solar charger with a battery big enoughYou must use solar cells to recharge the battery. Select (we call it solar collectors, but strictly speaking, a solar panel generally consists of a panel separate from the larger solar cells), solar charger, solar cells with larger
Sometimes the size of solar cells is not indicated in watts, but given the current and voltage (volts and amps), then the power amplifiers are Volts, multiply (W = IV), such as a specific solar cells could declare : 5.5Volts / 330 mA. Multiply by 5.50.33A found in watts, is therefore about 1.8 watts of output.
Due to these facts is a solar charger with some confidence that you can choose to meet your needs.
