A frame 10 for a photovoltaic module according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 12. The photovoltaic module can be applied to a photovoltaic power generation system. In the following description of the present application, the photovoltaic module is applied to a photovoltaic power generation system as an example.

As shown in fig. 1 to 8, a frame 10 for a photovoltaic module according to an embodiment of the present invention includes a frame body and a limiting structure.

Specifically, the frame body comprises a first installation part 101 and a second installation part 102 which are connected with each other, a first installation groove 1011 is formed on the first installation part 101, the edge of the photovoltaic body of the photovoltaic module is suitable for being matched in the first installation groove 1011, a second installation groove 1021 is formed on the second installation part 102, the cross section of the second installation groove 1021 is generally C-shaped, the opening direction of the second installation groove 1021 is opposite to the opening direction of the first installation groove 1011, and the pressing block 20 is suitable for being matched in the second installation groove 1021. The limiting structure is arranged on the second installation part 102 and is suitable for preventing the pressing block 20 from being separated from the second installation groove 1021.

For example, in the example of fig. 1 to 8, the opening direction of the first mounting groove 1011 may face to the right, the opening direction of the second mounting groove 1021 may face to the left, and the limiting structure is disposed in the second mounting groove 1021.

Referring to fig. 10, a first escape surface 2022 is formed on a side of the end surface of the free end of the compact mounting portion 202 adjacent to the compact body 201, and the first escape surface 2022 extends obliquely downward in a direction away from the compact body 201. From this, when the free end of briquetting installation department 202 stretched into second mounting groove 1021, can avoid the free end of briquetting installation department 202 to take place to interfere with second installation department 102 to make the free end of briquetting installation department 202 can stretch into second mounting groove 1021 fast in, improved photovoltaic power generation system's assembly efficiency.

In some alternative embodiments, as shown in fig. 10, an included angle between the first avoiding surface 2022 and the horizontal plane is α, where α satisfies: alpha is less than or equal to 30 degrees. When α > 30 °, an included angle between the first avoiding surface 2022 and the horizontal plane is too large, which may affect the structural strength of the compact mounting portion 202, so that the compact mounting portion 202 is easily deformed during mounting. Therefore, when the alpha satisfies the condition that alpha is less than or equal to 30 degrees, the structural strength of the briquetting mounting part 202 can be ensured, and the briquetting mounting part 202 can be mounted conveniently.

According to some embodiments of the present invention, as shown in fig. 9-12, the two side surfaces in the thickness direction of the pressing block body 201 are the first surface 2011 and the second surface 2012 respectively, the pressing block installation portion 202 extends from the above-mentioned other end of the pressing block body 201 along the thickness direction of the pressing block body 201 and toward the direction away from the first surface 2011, the connection between the pressing block installation portion 202 and the pressing block body 201 has the avoidance notch 207, and the avoidance notch 207 is located on the side where the first surface 2011 is located. When briquetting 20 is applied to photovoltaic power generation system, in the installation of briquetting 20, can be earlier with the one end cooperation of keeping away from of briquetting installation department 202 and dodging breach 207 in the second mounting groove 1021 of photovoltaic module's frame 10, later with the one end cooperation of dodging breach 207 that is equipped with of briquetting installation department 202 in the second mounting groove 1021 of frame 10 again, dodge breach 207 and take place to interfere when can avoiding the installation of briquetting 20 and first spacing arch 104, and briquetting 20 is simple with the mounting means of frame 10, can improve photovoltaic power generation system's assembly efficiency, thereby cost of labor when can reducing the installation of photovoltaic power generation system.
