• Trackers (mechanical structure move the angle cells
to follow the sun, increasing system efficiency, also including
motors, PLC, communication, protection).
• Combiners (junction boxes, including switching devices, with
several cables input and one cable output).).

.
• Switching devices and protection devices (to change PV
string configuration, protect from over currents, surge
voltages and earth faults etc.
• Distribution transformer (transforming low voltage high
voltage, grid connection often done high voltage
level). Large PV
systems often consist following main components:
• cells (combined strings, generating the power).
• Inverter (one several, converting the generated voltage
into 50Hz 60Hz, also including devices for switching,
protection and control).Applications solar
What power?
Photovoltaic (PV) power renewable energy source converting
sunlight directly into electrical energy using cells
