Abstract

The invention belongs to the technical field of photovoltaic panels, and provides a photovoltaic panel cleaning agent and a preparation method thereof. The photovoltaic panel cleaning agent comprises a detergent and an antistatic solvent, the detergent is prepared from the following components in percentage by mass: 4 to 10 percent of mixed alkali, 5 to 10 percent of nonionic surfactant, 2 to 5 percent of anionic surfactant, 0.8 to 2 percent of triethanolamine and the balance of water, the antistatic solvent comprises the following components in percentage by mass: 10-18% of a nonionic surfactant, 1-3% of a chelating agent, 2-4% of an antistatic agent, 15-25% of isopropanol and the balance of water. The surface of the photovoltaic panel cleaned by the cleaning agent is clean, bright and antistatic, and the cleaning effect of the photovoltaic panel is kept for a long time; the cleanliness after cleaning reaches 99% or above, and the cleanliness can still reach 90% or above after the cleaning agent is used for 3 months.
