Can the direct current from photovoltaic panels charge people

Can the direct current from photovoltaic panels charge people

When sunlight hits the cells on a solar panel, it produces a chemical reaction and generates direct current (DC). The current is used to charge the battery and can also be used to run appliances and other devices. The immediate danger depends on the interaction of several physical factors that determine how much. . In order to understand the type of radiation solar panels emit, we need to understand how these systems work. AC and DC power refer to the current flow of an electric charge. [pdf]
