43 requires exposed non-current-carrying metal parts of PV module frames, mounting systems, enclosures, and associated metal equipment to be bonded and connected to an equipment grounding conductor (EGC).
To successfully install solar photovoltaic power generation piles, careful planning and execution are essential. Prepare the ground appropriately, 3. Ensure compliance with safety regulations.
Solar panels and all mounting hardware (frame, rails, etc. ) weight does not exceed five (5) pounds per square foot (psf) or 45 pounds (lbs) concentrated load at each point of attachment or support, with a maximum weight of two-hundred (200) lbs per framing member.
Measure Total Distance (L): Calculate the full round-trip length in feet for the conductor run. Consult the Chart or Formula: Use the distance, current, and voltage drop limit to find the minimum acceptable wire size.
Modern PV backsheet components must comply with UL 1703 (fire safety), IEC 61730 (module construction requirements), IEC 61215 (design qualification), and IEC TS 62788-2 (material qualification sequences). Region-specific certifications include CQC China, JET Japan, and BIS India.
