Solar systems for generating electric energy are photovoltaic systems. These systems basically consist of four components.
1. Solar panel which is meant for transforming solar radiation energy into electric current.
2. Control unit which is meant for regulating electric current to be stable.
3. Battery which is meant for accumulating electric energy to use it later for different purposes.
4. Voltage transducer which is necessary for converting 12V DC into 110 or 220 V AC.
