During high temperatures, the panel's temperature increases, leading to increased resistance within the PV cells..
During high temperatures, the panel's temperature increases, leading to increased resistance within the PV cells..
This is due to an increase in resistance of the circuit that results from an increase in temperature. Likewise, resistance is decreased with decreasing temperatures. [pdf]
Proper grounding of a photovoltaic (PV) power system is critical to helping ensure electrical safety during its lifetime. PV equipment needs to be properly bonded, in addition to code-compliant grounding, so that the low current flows on metal parts can facilitate the operation of over current and ground-fault protection. .
UL 3703, the Standard for Solar Trackers, involves rigorous inspection and evaluation of a tracker platform and also references UL 2703 for electrical requirements related to the mounting, bonding and grounding. .
The following standards apply to electrical and electronic equipment in select industrial locations: 1. IEC 61000-6-2: Electromagnetic compatibility (EMC) - Part 6-2: Generic standards - Immunity standard for industrial. [pdf]
