How does the solar system works

Industrial development of photovoltaic solar modules goes back in the 50-year primarily in order to use the power of satellites orbiting the Earth. From then on ancient technology development has reached fantastic proportions in terms of ease of use power reliability and price. All of the above provide the possibility of applying the Solara in places where hitherto the electricity was not available or the supply was unreliable

Working principle is simple in essence: Some materials such as single crystal silicon has a physical characteristic that is exposed to sunlight, generates electricity. In the module, which consists of a series of interconnected plates parallel to serial connection is obtained by combining voltage and current suitable for charging a standard battery (6, 12 or 24 V). This ensures that the module produces an electrical voltage and intensity suitable for directly charging the battery or DC powered consumer. Current magnitudes generally proportional to the surface of the module and insolation (solar radiation intensity). In monocrystalline and polycrystalline modules that the surface is 2-3 times smaller than that of amorphous modules.

A typical scheme of the solar system at 12 V DC with the presentation of the main components:

A. Solar Module converts sunlight into electricity.
B. Battery.
C. Typical consumers at 12 V DC.

The more complex system showing major components and the drive for consumers to 220 V 50 Hz:

A. One or more solar modules.
B. Controller Battery charging: to prevent overloading and deep discharging the battery.
C. Battery system.
D. Converter: 12V DC voltage from the battery into 220V, 50Hz.
E. Typical consumers at 12 V DC.
F. Typical consumers at 220 V, 50 Hz.

The above examples are just the most common case. Sometimes as in crpjenje water systems modules directly fed by a pump so that the system only works by day as there is sun so batteries are unnecessary. Depending on the type of multiple modules can be connected in series parallel combinations to obtain the desired energy suitable for voltage and current levels. Virtually no restrictions on the installed capacity of the system.
