The invention discloses a superhydrophobic self-cleaning photovoltaic glass coating solution and a coating process thereof. The superhydrophobic self-cleaning photovoltaic glass coating solution comprises the following components in parts by weight: 20 to 30 parts of waterborne fluorine-carbon emulsion, 25 to 35 parts of epoxy silicone oil, 15 to 25 parts of polysiloxane modified polyurethane, 6 to 12 parts of polytetrafluoroethylene, 5 to 7 parts of fullerene, 4 to 6 parts of titanium dioxide, 10 to 15 parts of a light anti-reflection agent, 2 to 8 parts of an oil removal agent, and 0.2 to 1part of a silane coupling agent, wherein the light anti-reflection agent comprises the following components by weight percent: 5 to 9 percent of yttrium lithium fluoride, 2 to 6 percent of magnesium fluoride, 0.7 to 1.5 percent of lithium tantalate, 0.3 to 0.5 percent of bismuth oxide, 2 to 8 percent of zirconium oxide, and 85 to 90 percent of silicon dioxide aerosol. The coating process comprisesthe following steps: atomizing the coating solution under the conditions of 25 to 35 MPa and at 100 to 120 DEG C, spraying at a flow rate of 0.3 to 0.45 g / s, and naturally curing when the to be deposited thickness reaches 0.25 to 0.3 mm. According to the superhydrophobic self-cleaning photovoltaic glass coating solution, the surface tension of glass can be reduced by virtue of a hydrophobic medium consisting of the waterborne fluorine-carbon emulsion, the epoxy silicone oil, polytetrafluoroethylene and the like, so that the dustproof and waterproof performance can be achieved; and the light transmittance of the film can be improved by utilizing the anti-reflection agent, and the scales can be removed by virtue of the fullerene / titanium dioxide nano composite.
