Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic module technical field, concretely is a kind of tile assembly photovoltaic module. BACKGROUND

[0002] At present, with the cost of photovoltaic cell piece drops, make the construction and installation distributed photovoltaic power generation system in city have been very popular. The construction of distributed power station is transferred from ground to building and structure in large quantities, form roof photovoltaic, photovoltaic carport, photovoltaic curtain wall, photovoltaic corridor and photovoltaic container and other multiple application scenarios. With the increase of application scenario, new technical requirements are also put forward for photovoltaic products, such as: waterproof function, beautiful appearance matching with building, lightweight characteristics, modularization easy to install, easy to clean and maintain, easy to repair characteristics, good heat dissipation and moderate price. In order to cater to the new market demand, photovoltaic power generation product industry derives various creative characteristic products, for example: color photovoltaic module (increased color), waterproof photovoltaic support (increased waterproof function), frameless photovoltaic module (enhanced self-cleaning ability), all-black photovoltaic module (reduced the conspicuousness of appearance color), photovoltaic flat tile (enhanced overall modeling) and photovoltaic curved tile (increased antique glazed tile modeling) and so on.

[0003] However, the characteristics of these characteristic products are outstanding but very scattered, and multiple characteristics cannot be concentrated in one product. At the same time, most of the photovoltaic products used on the roof, especially photovoltaic flat tiles and BIPV products, generally do not consider the natural ventilation capacity of the system, resulting in poor heat dissipation performance of the photovoltaic product, affecting power generation. Although the photovoltaic curved tile has strong three-dimensionality, good waterproof and water guide self-cleaning performance, however, its curved modeling and lamination packaging process of high-efficiency crystalline silicon cell piece are not matched, and there is a higher photovoltaic cell damage rate in production. If flexible power chip is used, the problem of low unit plane power generation efficiency will be faced, which further leads to a substantial increase in the cost of photovoltaic product single tile (power generation power and efficiency decrease, but auxiliary material cost remains unchanged). On the other hand, the existing photovoltaic curved tile product has photovoltaic cell pieces in multiple directions, but only one way of power output. Since different direction cell pieces (multiple wave surfaces) will receive different intensity of solar radiation, the output power of cell piece will be limited by the bucket effect. At the same time, the photovoltaic tile product under the existing technology must be installed on the purline or keel of the roof, that is, the installation worker can only install the photovoltaic tile product one by one on the roof, which has low installation efficiency and is not suitable for mass production.
