[0022] Reference Figure 1 The utility model provides a curved power generation tile, comprising a power generation tile body 1, a water retaining strip 2 and a junction box 3. The power generation tile body 1 is in a curved shape, and aluminum frames 4 are arranged on both sides of the power generation tile body 1 to play a protective role and effectively prevent damage from collision. The water retaining strip 2 is arranged horizontally on the top of the power generation tile body 1, and the water retaining strip 2 is bonded and sealed to the power generation tile body 1.

[0023] The junction box 3 is arranged at the bottom of the power generating tile body 1 and is electrically connected thereto. The junction box 3 is provided with an MC4 connector, which is a commonly used connector design for solar panels and has the advantages of stable performance, reliable contact, and waterproofness.

[0024] The power generation tile body 1 includes a front panel 101, a front packaging film 102, a photovoltaic power generation chipset 103, a rear packaging film 104 and a rear panel 105 which are arranged in sequence from top to bottom. The photovoltaic power generation chipset 103 is packaged by the front packaging film 102 and the rear packaging film 104. A certain area is left between the edge of the photovoltaic chipset 103 and the edge of the curved power generation tile. This area is an insulating area for setting the packaging film. The junction box 3 is electrically connected to the photovoltaic chipset 103 in the power generation tile body 1.

[0025] The front packaging film 102 and the rear packaging film 104 are made of any one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and trimethylbenzoyl-diphenylphosphine oxide. As a preferred option, the polyolefin elastomer is a polymer of ethylene and butene or a polymer of ethylene and octene.

[0026] The photovoltaic power generation chipset 103 is any one of a F-PSCs cell, a HIT cell, a PERC cell, an IBC cell, a SHJ cell, a TOPCon cell and a HBC cell.

[0027] During installation, multiple curved power generating tiles are required to form a complete roof. When it rains, rainwater starts to gather and flow downward from the top curved power generating tile. If no measures are taken, it will cause too much rainwater to gather on the curved power generating tiles below, affecting the power generation efficiency. Therefore, a water retaining edge is formed on the top of the power generating tile body 1 using a water retaining rubber strip 2. When it rains, each power generating tile becomes a separate panel. The rainwater flowing down from the upper power generating tile will not flow directly to the panel of the lower power generating tile, but will flow down from both sides of the power generating tile body 1 under the action of the water retaining rubber strip 2, which can effectively prevent the lower power generating tile panel from being washed by a large amount of rainwater, so that the power generation efficiency of each power generating tile is maintained at the best state.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
