Currently, due to the increase in renewable energy sources, photovoltaic solar energy has played an important role in this growth. However, it is inherent in systems that they are installed in an exposed manner, so as to allow the direct incidence of sunlight. Due to this exposure, the systems become quite vulnerable to the effects of atmospheric discharges. The damage caused by atmospheric discharges to the systems results in a reduction in the useful life or even the destruction of components such as modules, inverters and monitoring systems, situations that will certainly have an impact on maintenance costs and consequently increase the amortization time of the investment . This paper presents the current technical specifications, as well as the norms and regulations that approach this theme. It specifies the main requirements and methods adopted for the design of surge protection devices and lightning protection systems in photovoltaic arrays. With regard to one of the methodologies, the present work develops three case studies already implemented in the cities of Florianópolis and Palhoça. Data were collected through technical visits, and the approach used in data analysis was qualitative.
