Explaining Functions of Solar Panels (Placas Solares)

The sun rays or light is what is called solar energy that is used everywhere now. Solar energy is needed by all planets including the Earth where we, human beings live. But this natural energy cannot be used directly in most cases. It cannot be used alone in so many applications. It is the solar panels (placas solares) that have the capacity to collect solar energy which can later be converted to electric energy (electricity) that can be used for many applications.

These solar boards or panels are also photovoltaic boards that are interconnected solar cells. Many units of solar cells are connected together to be able to generate more solar energy.

Photovoltaic or solar panels (placas solares) are produced from certain materials that are known as semiconductors. The most common semiconductor in use is c-Si or crystalline silicone. This material is arranged in layers in such a way that two opposite charges or layers will constitute a solar cell. When the sun rays which are photons now collide with solar cell which is the silicone, some electrons will be released.

These electrons will travel through different layers of the semiconductor and generate electricity or electrical energy (current).

The electric current produced by this solar circuit or system is direct current (DC) and is not suitable to be used at home or office. There is need to change or convert this DC into another electric current called alternating current (AC). This AC is what electricity grid provides to residential and commercial buildings.
