Photovoltaic module mounting bracket system applicable to marine environment

The invention discloses a photovoltaic module mounting bracket system applicable to a marine environment. The photovoltaic module mounting bracket system comprises at least one group of mounting brackets; the mounting brackets comprise a front bracket and a back bracket; the front bracket comprises a front base and a supporting part rotationally arranged on the front base; the back bracket comprises a back base with adjustable height and a supporting part rotationally arranged on the back base; and photovoltaic modules are mounted on the supporting parts of the front bracket and the bracket. By virtue of the photovoltaic module mounting bracket system, angle adjustability of the photovoltaic module is realized, and mounting angles can be selected in different sections according to onsite actual conditions; and therefore, the photovoltaic module mounting bracket system can be applicable to a fixed sea area plane and particularly suitable for a sea level where the photovoltaic modules can move along with large-
