Embodiment Construction

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0020] like Figure 1-Figure 6 As shown, a photovoltaic shingled assembly for preventing battery strings from being disconnected includes a backplane 20 and a plurality of battery strings 1. Each battery string 1 includes a plurality of battery cell groups 2 that are structurally connected in series. The cell group 2 Including the first type of battery sheet 3 and the second type of battery sheet 4 that are overlapped end to end, the back of the first type of battery sheet 3 and the second type of battery sheet 4 have symmetrically distributed positive electrodes and negative electrodes, t...

Abstract

The invention belongs to the field of photovoltaic technology, and particularly relates to a photovoltaic imbricate assembly capable of preventing a battery string from being broken. Comprising a back plate and a plurality of battery strings, each battery string comprises a plurality of battery piece groups which are connected in series and in lap joint in structure, each battery piece group comprises a first battery piece and a second battery piece which are in lap joint end to end, and positive electrodes and negative electrodes which are symmetrically distributed are arranged on the back faces of the first battery pieces and the second battery pieces. The polarities of the electrodes on the back surfaces of the first battery piece and the second battery piece and on the same side are opposite; according to the invention, by arranging the conductive region and filling the conductive material, when the first welding strip or the second welding strip at the top of the conductive region is broken, the broken first welding strip or the broken second welding strip can still be electrically connected through the conductive material, so that the situation that the battery string is broken due to the breakage of the welding strip is avoided.

Description

technical field [0001] The invention belongs to the field of photovoltaic technology, and in particular relates to a photovoltaic shingled assembly for preventing battery strings from being disconnected. Background technique [0002] Photovoltaic (PV or photovoltaic), short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Photovoltaic technology has many advantages: for example, there are no mechanical moving parts; in addition to sunlight, no other "fuel" is required, and it can work in direct and oblique sunlight; at the same time, solar modules do not require maintenance and minimize operating costs. [0003] The collection current density of the photovoltaic modules in the traditional way of connecting photovoltaic cells in series is not uniform, the power loss of photoelectric conversion is lar...
