Novel photovoltaic module

Abstract

The invention discloses a novel photovoltaic module, which is characterized by comprising a bottom plate, wherein the upper half part of the bottom plate is an installation part, the lower half part of the bottom plate is an exposed part, the installation part is provided with a plurality of photovoltaic cell panels connected in series, and the exposed part is provided with a connecting wire and a junction box; and the photovoltaic cell panel is electrically connected with the junction box through the connecting wire. According to the photovoltaic module, the problem that the bottom of the photovoltaic module is shielded by dust is fundamentally avoided by arranging the exposed part, the connecting wire and the junction box are arranged at the exposed part, and the current direction of the photovoltaic cell panel is changed, so that the internal resistance of the cell panel is reduced, and the influence caused by subfissure of a cell piece is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of solar cell components, and more specifically relates to a new type of photovoltaic component. Background technique [0002] At present, a photovoltaic module is a device that converts solar energy into electrical energy by using the photovoltaic effect. At present, our common ones include double-glass modules, double-sided battery modules, half-chip modules, multi-busbar battery modules, laminated battery modules and conventional single-glass modules. Components, they are composed of tempered glass, POE / EVA, battery sheet, TPT laminated at high temperature to form a composite layer. At present, the photovoltaic module adopts the manufacturing process of matching glass with a length and width of 1643*985 / 1950*985 with cells of 158.75, 166, and 210 sizes, and at the same time adopts a glass process with a length and width of 2009*992. In these size packaging processes, no matter it is the best fixed tilt a...

Problems solved by technology

[0003] However, we only changed the shape of the battery sheet in the traditional process, but failed to design the layout. Therefore, the components are affected by environmental factors, dust accumulation and The shade of the tree will cause a loss of about 5% to 10% of the power generation

At the same time, the impact of the natural environment will cause changes inside the components, resulting in fires and other phenomena

However, photovoltaic modules have a certain inclination angle during installation, so that the lower part of the module will be covered by dust and tree shade in harsh natural environments, and even the glass will be corroded, resulting in power loss, hot spots, and even fire. and other phenomena

[0004] Therefore, it is an urgent problem for those skilled in the art to provide a new version of photovoltaic modules, reduce the internal resistance of cells and the risk of hidden cracks, and avoid the reduction of power generation efficiency due to problems such as wind and sand.
