1. A method for connecting photovoltaic modules in series to define a string of photovoltaic modules, applicable to a computer device, wherein each of the photovoltaic modules is a basic power generation unit of a photovoltaic system, the method comprising:
acquiring position information of n photovoltaic modules to be connected, wherein n is an integer greater than 3 and the n photovoltaic modules are already deployed;
categorizing the n photovoltaic modules into m partitions based on the position information of the n photovoltaic modules, wherein each of the partitions comprises a plurality of photovoltaic modules, and m is an integer greater than 1 and less than n;
generating k candidate connection solutions of an ith partition in the m partitions, wherein the ith partition comprises ni photovoltaic modules, and each of the k candidate connection solutions uses a different one of the ni photovoltaic modules as a starting point, and obtains at least two strings of photovoltaic modules by simulating connection of the ni photovoltaic modules according to a preset connection solution, i is a positive integer less than or equal to m, ni is an integer greater than 1 and less than n, and k is an integer greater than 1;
calculating estimated cable use amounts respectively corresponding to the k candidate connection solutions; and
selecting a target connection solution corresponding to the ith partition from the k candidate connection solutions based on the estimated cable use amounts respectively corresponding to the k candidate connection solutions.
