Electrical Hazards in Solar Photovoltaic (PV) Systems
Solar PV systems generate direct current (DC) power from sunlight. This energy is then commonly inverted to alternating current (AC) to supply loads or is interconnected to electrical grids. The process of transforming DC to AC power is performed through inverters. The energy created can also be transferred to battery packs for storage.
