Guide for Photovoltaic and Solar Energy Systems, and the Best Solar Products

Photovoltaic or Solar Energy System

The energy crisis in the world is the lack of non renewable energy resources as petroleum products, natural gas and coal. In addition to, the increase of population all over the world leads us to the renewable energy resources. One of the best and efficient renewable energy sources is the photovoltaic system. The photovoltaic system uses the sun light to generate electricity. Simply, the solar panels absorb the sun light and transform it to electric power. The conventional photovoltaic or solar system consists of solar panel, charge controller, battery and inverter. The solar panel transforms the absorbed sun light to DC power. This DC power is regulated by the charge controller, in order to charge the battery. Thus, there is a reliable DC power source which is the battery. And for the AC appliances, the inverter transfers the DC power from the battery; which passes through the charge controller; to pure AC power.

Thus, the charge controller elongates the lifetime of the battery, as it stabilizes the battery charging and discharging current. Also, it protects the battery from being overcharged and from overvoltage. And the inverter supplies pure output AC power to your appliances which guarantee the safety of your home devices.

The Solar Panel

The solar panel consists of small solar cells connected together to form the solar panel. The solar cell receives the sun light that falls on it. And in general, the sun light has an energy source called photons. These photons supply energy to the free electrons of the solar cell. The energy absorbed; by the solar cell free electrons; enables the mobility of these electrons. This mobility of the electrons; for one end of the solar cell to the other; causes energy transfer through the solar cell and this is the production of the DC current. Thus, the solar panel converts the sun light to electric power. The solar panel is usually made of silicon, which is a semiconductor material.

Types of Solar Panels or PV modules:

The types of PV modules that are widely used in the market are mono-crystalline, poly-crystalline, thin film, Perovskite and multi-junction solar panels.
