Earthing Solar Panel Frames

Even if you seldom have electrical storms all it takes is one lightning strike or a single lose wire and all the.

Earthing solar panel frames.

Only 18 left in stock order soon. Good earthing of pv array frames will improve the resistance of the pv system to lightning induced surge damage. Of all the elements of a u s. First it is required to ground all pv systems second a properly grounded system will help protect you and your employees from unintentional shocks and possible deaths.

It also limits the voltage to ground that can occur on normally non current carrying metal components ranging from frames and rails to conduit and enclosures. Including the metal frames of pv modules can present electrical shock and fire. Solar installation the grounding portion of the system may well be the most important. The optimum earthing system for personal safety may be at odds with the best system with regards to fire prevention.

Cable lugs earthing termination and bonding cables are to be fixed by stainless steel bolts washers and penetrating washers to aluminium frames clause 4 4 2 2 earthing or bonding connections must be arranged so that the removal of a single module earth connection will not affect the continuity of the earthing or bonding connections to any. The solar america board for codes and standards solar abcs is a collaborative effort. Failure to ground the entire system to include all the individual pieces can be devastating especially in an area that experiences lightning on a regular basis. Equipotential zone defining whether a pv array lies within the equipotential zone is a key step.

Lightning and related static discharge is the number one cause of sudden unexpected failures in pv systems lightning does not have to strike directly to cause damage to sensitive electronic equipment such as inverters controls radios and entertainment equipment it can be miles away and invisible and still induce high voltage surges in wiring especially in long lines. When installing a solar photo voltaic system pv it is extremely important all the equipment is grounded correctly. Bonding and grounding pv systems ensures public safety as well as the safety of pv installers and field electricians said andy zwit codes and standards manager at ilsco.
