应用于光伏(PV)系统的接地概念可能涉及裸露的导电部分(如面板的金属框架)以及发电系统(光伏系统的带电部分，如电池)。只有通过变压器将PV系统与电网进行电分离(例如通过变压器)，PV系统才能接地。PV绝缘系统显然对接触带电部件的人更安全;事实上，带电部分对地的绝缘电阻不是无穷大的，然后通过这种电阻返回的电流穿过人。由于对地绝缘电阻降低，当植物对地电压和植物尺寸增加时，该电流上升。此外，由于时间的推移和湿度的存在，绝缘子的生理衰减会降低绝缘电阻本身。因此，在非常大的植物中，通过与带电部分接触的人的电流可能导致触电，因此，只有在小型植物中才存在接地系统的优点。

The grounding concept applied to photovoltaic (PV) systems may involve the exposed conducting part (such as the metal frame of a panel) as well as the generating system (the live part of a photovoltaic system, such as a battery). PV systems can only be grounded if they are electrically separated from the grid by a transformer, for example. PV insulated systems are obviously safer for people touching live parts; In fact, the insulation resistance of the charged part to the ground is not infinite, and the current returned through this resistance passes through the person. This current rises as the plant voltage to earth and plant size increase due to the decrease of insulation resistance to ground. In addition, due to the passage of time and the presence of humidity, the physiological attenuation of the insulator reduces the insulation resistance itself. Therefore, in very large plants, electric current through a person in contact with a live part can result in electrocution, so the advantages of a grounding system exist only in small plants.
