ELECTRICAL WORK
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.

Keep children well away from the system while transporting and installing mechanical and
electrical components.

Completely cover the module with a solid material like a blanket during installation to keep electricity from
being generated. Do not touch the components or the end of live wires.

Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic devices while
installing or troubleshooting photovoltaic systems.
Use only insulated tools that are approved for working on electrical installations.
