Abstract

The invention provides a photovoltaic module. The module includes four battery string sets and four bypass diodes; the four battery string sets are sequentially connected in series; each of the battery string sets includes multiple battery strings connected in parallel with each other, and each of the battery strings includes multiple battery pieces sequentially connected in series; and each of the battery string sets is correspondingly provided with one of the bypass diodes in parallel, a positive electrode of each of the bypass diodes is electrically connected to a negative electrode of eachof the battery strings of each of the battery string sets, and the negative electrode of each of the bypass diodes is electrically connected to the positive electrode of each of the battery strings of each of the battery string sets. The photovoltaic module is based on the photovoltaic module with a fixed version size, the number of the bypass diodes is increased, when the battery pieces are blocked, the area of the battery pieces that stop working is reduced, and the output power of the photovoltaic module is furthest maintained when occlusion occurs.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a photovoltaic module. Background technique [0002] Photovoltaic modules, also called solar panels, are the core part of solar power generation systems. Their function is to convert solar energy into electrical energy. The piece (156 mm x 156 mm) is evenly cut into two pieces (156 mm x 78 mm), and then electrically connected with a soldering tape. The theoretical loss of power caused by the series resistance is reduced to a quarter of the original whole module, and the temperature of the power generation operation is also lower than that of the whole photovoltaic module, so that the overall power of the half photovoltaic module is significantly improved. [0003] Currently, refer to figure 1 , a common half-cell photovoltaic module includes six regions A, B, C, D, E, and F and three bypass diodes 1, each of which is composed of a plurality of series-connected cells 2, an...
