    ELECTRICAL WORK Installation of the solar photovoltaic system  This guide contains information regarding the installation and safe handling of solar photovoltaic module. All instructions should be read and understood before attempting to install. If there is any question, please contact our support department for further explanation. The installer should conform to all the safety precautions listed in this guide when installing the module.
  • Page 16 When disconnecting wires from a photovoltaic module that is exposed to sunlight, an electric arc may result. Such arcs may cause burns, combustion and may otherwise create problems. Therefore, be extremely careful! Photovoltaic solar modules convert light energy to direct-current electrical energy. They are designed for outdoor use.
  • Page 17 Solar modules produce electrical energy when light strikes on their front surface. The DC voltage may exceed 30V. If modules are connected in series, the total voltage is equal to the sum of the individual module voltages. If modules are connected in parallel, the total current is equal to the sum of individual module currents.
