When installing the system, abide with all local, regional and national statutory regulations.
Obtain a building permit where necessary.
Safety precaution for installing a solar photovoltaic system
Solar modules produce electrical energy when light shines 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 an opaque material during installation to keep electricity from
being generated.
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.
Abide with the safety regulations for all other components used in the system, including wiring
and cables, connectors, charging regulators, inverters, storage batteries and rechargeable batteries,
etc.
Use only equipment, connectors, wiring and support frames suitable for a solar electric system.
Always use the same type of module within a particular photovoltaic system.
The electrical characteristics are within ±10 percent of the indicated values of Isc, Voc, and
Pmax under standard test conditions (irradiance of 100mW/cm2, AM 1.5 spectrums, and a cell
temperature of 25°C (77°F))
Under normal outdoor conditions the module will produce current and voltages that are different
than those listed in the date sheet. Data sheet values are values expected at standard test conditions.
Accordingly, during system design, values of short-circuit current and open-circuit voltage should
be multiplied by a factor of 1.25 when determining component voltage ratings, conductor
ampacity, fuse ratings and size of controls connected to the modules or system output.
Product identification
Each module has three labels on its rear side providing the following information:
Nameplate: describes the product type; rated power, rated current, rated voltage, open circuit
voltage, short circuit current, all as measured under standard test conditions; weight, dimension
etc.; the maximum system voltage 1000 volts DC and is shown on the nameplate. Maximum fuse
