3. 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 capacity, fuse
ratings and size of controls connected to the modules or system output.
