Warning and safety
- Installing solar photovoltaic systems may require specialized skills and knowledge. The installer assumes all risk of injury, including risk of electric shock. Module installation should be performed only by qualified persons.
- Contact with a large-scale PV system is potentially hazardous.
Each individual module may produce DC voltages greater than 40 volts when the sufficient sunlight or other sources illuminate the module surface. When the modules are connected in series, voltage is cumulative. When the modules are connected in parallel, current is cumulative. High voltage and current could present an increased hazard and may cause serious injury or death. Therefore, be extremely careful!
- The module should be carefully unloaded to avoid damage to man-made causes when they are transported to installation locations.
- Please carefully check the products are consistent with the list of goods.
- Do not attempt to disassemble or discard any components of the module.
- Do not touch live wires/terminals located in the module junction box.
- Keep children well away from the system while transporting and installing mechanical and electrical components.
- Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic devices while installing or troubleshooting photovoltaic systems
- Do not expose solar module to sunlight that is concentrated with mirrors, lenses or similar means.
- The module should avoid being shaded to prevent module hot spots at any time of the day, because it will reduce the output power.
- Do not install near firing and flammable material.
- Do not stand or step on module although module glass is strong.
