3 Type of solar panel

3 Type of solar panel. Solar panel / solar cells to modify the intensity of sunlight into electrical energy. Solar panels / solar cell produces a current used to charge the battery.

Solar panel / solar cell is composed of solar, which generate electricity from light intensity, the intensity of light decreases (cloudy, rainy, cloudy) the electricity generated will also decrease.

With the addition of solar panels / solar cell (expansion) is to add solar energy conversion. Typically a solar panel / solar cell to a certain size to provide specific results. For example, the size of a cm x b cm power DC (Direct Current) for x watts / hour
Type of solar panel / solar cells:
Poly-crystalline,
It is the solar / solar panel has a casual arrangement of the crystals. Compound type requires a larger surface area than other types mono-crystalline to generate the same power, but can produce electricity at the time was cloudy.

Mono-crystalline,
And panels more efficient, resulting in extensive power to the unit higher. High efficiency up to 15%. The weakness of the panels of this type is not a good place to work less sunlight (shadow) the yield would drop drastically the weather is cloudy.

Amorphous
Amorphous silicon (a-Si) has been used as a photovoltaic solar cell material for calculators for some time. Although they are lower performance than traditional c-Si solar cells, this is not important in calculators, which use very low power. a-Si's ability to be easily deposited during construction more than makes up for any downsides.

More recently, improvements in a-Si construction techniques have made them more attractive for large-area solar cell use as well. Here their lower inherent efficiency is made up, at least partially, by their thinness - higher efficiencies can be reached by stacking several thin-film cells on top of each other, each one tuned to work well at a specific frequency of light. This approach is not applicable to c-Si cells, which are thick as a result of their construction technique and are therefore largely opaque, blocking light from reaching other layers in a stack.

The main advantage of a-Si in large scale production is not efficiency, but cost. a-Si cells use approximately 1% of the silicon needed for typical c-Si cells, and the cost of the silicon is by far the largest factor in cell cost. However, the higher costs of manufacture due to the multi-layer construction have, to date, make a-Si unattractive except in roles where their thinness or flexibility are an advantage.
