Solar Battery Charger is found to charge any battery, when we do not have any access to any power grid or electricity. In that case, we can say that these chargers are required when we do not have any wall socket to plug into. The working procedure of the solar charger is quite simple. After charging any battery, we allow this charger to get recharged in the sun. In that case, solar panel of the battery charger gathers energy from the sun and then it gets converted into electricity. After gathering energy from sun, the electricity produced is used to charge a battery. And then, the charged battery can be used to run any equipment.
These chargers are found in different categories. And, power of these chargers also differs from one to another. Several solar chargers use different types of solar panels and the amount of power generated by the charger is completely dependent on the size of the panels. Different solar cells are responsible for making these solar panels. These cells are those units, which are responsible for creating electricity out of sunlight. Depending upon the number of solar cells present in the solar panel, the amount of electricity is counted. Thus, in that case, bigger sized solar panels are responsible for producing more energy. And of course, smaller solar panels are responsible for generating less energy.
Some solar chargers are found to work with simple AA batteries and these batteries use to make flashlight work. Few chargers work well with special batteries, which can be used to charge other equipment like, iPods, cameras, cell phones, MP3 players etc. Few chargers are used to charge the batteries of laptop or computer. Thus, it is to say that depending upon the requirement of the battery, this kind of charger should be selected.
Now, one question might come in our mind that instead of running any equipment directly from the solar panel, why the solar battery charger is used to charge a battery. In that case, we must understand that if our equipment is charged directly from the solar panel, then operating the equipment on a rainy day or at night or indoors would not be possible. Also, to charge the equipment directly from the solar panel, we need to leave the equipment outside under the sun. In that case, chances are there that sun ray can damage the equipment. Or, keeping the equipment in an open environment would damage the product anytime.
