High-transmittance full-glass photovoltaic guardrail

Abstract

A high-transmittance full-glass photovoltaic guardrail comprises at least one photovoltaic guardrail assembly, each photovoltaic guardrail assembly comprises a photovoltaic guardrail single body, a photovoltaic junction box and a fixed base, the photovoltaic junction box is embedded in the fixed base, and the bottom of each photovoltaic guardrail single body is embedded and fixed in the fixed base and electrically connected with the photovoltaic junction box. Each photovoltaic guardrail single body is of a multi-layer structure and at least comprises a photovoltaic crystalline silicon cell layer, each photovoltaic crystalline silicon cell layer comprises a plurality of photovoltaic crystalline silicon cell strings which are arranged in an up-down array mode, and the photovoltaic crystalline silicon cell strings are connected in series and in parallel and electrically connected with the photovoltaic junction box through a confluence conduction band. The position, between every two adjacent photovoltaic crystalline silicon cell strings, of each photovoltaic guardrail single body is a guardrail light-transmitting area. The high-light-transmittance full-glass photovoltaic guardrail provided by the invention is a full-glass guardrail, and has the characteristics of high adaptability with a building, good light transmittance and better appearance.

Description

technical field [0001] The invention relates to the technical field of photovoltaic buildings, in particular to a high-transmittance all-glass photovoltaic guardrail. Background technique [0002] Driven by the introduction of relevant policies to support green buildings and nearly zero-energy buildings in various countries around the world, BIPV products (Building Integrated Photovoltaic Products) will usher in a market explosion period, and its application has also expanded from the early single roof to curtain walls , Sunshade shutters, platforms, carports and other scenes. On the south facade of some buildings, there are still some application scenarios to be developed in sunny areas, such as glass guardrails in residences, hotels, parks and other places. [0003] In the above-mentioned application scenarios to be developed, such as balconies of villas, hotel apartments, and courtyards of sea-view rooms, all-glass guardrails with better appearance and light transmission...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned application scenarios to be developed, such as balconies of villas, hotel apartments, and courtyards of sea-view rooms, all-glass guardrails with better appearance and light transmission tend to be used, while the appearance of photovoltaic glass in photovoltaic guardrails is suitable for application scenarios. Poor compatibility

At present, the appearance of most of the existing photovoltaic glass directly adopts the appearance of photovoltaic modules, that is, the arrangement of crystalline silicon cells in full series. The dense silver-white ribbons greatly reduce the aesthetics of the photovoltaic guardrail, thereby reducing the adaptability of the photovoltaic guardrail product to the scene

[0004] At the same time, if the photovoltaic guardrail is applied to the ab
