This invention provides a modular passive temperature control design optimization method and system for single-sided photovoltaic modules. Based on typical daily meteorological parameters throughout the year, the first heat transferred from the back of the photovoltaic module to the modular passive temperature control device is obtained based on the energy conservation relationship. The second heat transferred from the back of the photovoltaic module to the modular passive temperature control device is obtained based on the heat storage of the phase change material and the heat dissipation of the heat pipe under a set evaporation section area calculated based on the equivalent thermal conductivity. Iterative calculations are performed to obtain the photovoltaic module backsheet temperature such that the difference between the first and second heat is less than a set threshold. The obtained photovoltaic module backsheet temperature guides the configuration of phase change parameters and heat pipe parameters. This invention, by changing the parameters and configuration of the phase change material and heat pipe, enables the modular temperature control device to adapt to the temperature control requirements of photovoltaic modules under different climatic and solar radiation conditions.
