Solar Cell phone Chargers: A “Green” Way to Charge your Mobile Phone
Very few people know about alternative ways of charging their mobile phones and other electronic gadgets. However, it is possible to charge these gadgets without having to rely on electricity. For instance, unknown to many, solar cell phone chargers are available in the market.
But how do solar cell phone chargers work, exactly, and how efficient are these environmentally-friendly products?
The design or appearance of these chargers often varies depending on the brand or model, but they are generally lightweight; a few of them are even small enough to fit inside your pocket. These charger has a small solar panels that stores energy.
A few models have panels that look like windmills, although most have more ergonomic designs for easy—and even chic—handling. Some models even allow you to simply stick the panels on a window to generate energy from the sunlight. Others can be placed around your arm or even a bicycle.
Obviously, this means you can bring the charger anywhere. Many mobile phone owners who have this charger keep it as an alternative means to charge a phone in case of a power outage or when there is no possible source of electricity within their vicinity.This kind of technology is no longer new. The photons are converted into electric current by the solar panels or cells, which agitate the light particles and turn them into electrons.
1° Take Amp/hour rating of the battery and Divide by the charger rating (in amperes) (*) and then add about 10% for the extra time to top off the battery,
(*) “Watt = Ampere x Volts” “Ampere= Watt/Volts” “Volt= Watt/Ampere”
(Example): To Calculate how much time You’ll need to charge the battery with a 15 Watt solar charger You’ll need:
1. Calculate the Ampere per hour of the charger: 15 Watts /12 Volts = 1,25 Amperes
2. Calculate the division: 50 amp hours / 1,25 amperes = 40 Hours of direct sunlight
3. Add 10%: 4 hours

Imagine that you could climb an imaginary mountain whose summit pokes above the Earth’s atmosphere (It would be about ten times higher than Mt. Everest). If you threw a baseball from the mountain top, it would fall to the ground in a curving path. Two motions act upon it: trying to go in a straight line and falling toward Earth. The faster you throw the ball, the farther it will go before it hits the ground. If you could throw the ball at a speed of 17,000 mph, the ball wouldn’t reach the ground. It would circle the Earth in a curved path; it would be in orbit. (It would be traveling at 5 miles per second and take about ten minutes to cross the United States.) This is the speed needed to put satellites into orbit, which is why the Space Shuttle and other satellites require such powerful boosters.
