At this time, the first side cap 10 is mounted on the first solar cell panel 400, the second side cap 10' is mounted on the second solar cell panel 400', and the first side cap ( 10) and the second side cap 10' are sequentially slide-inserted into the frame 300, the first terminal part 110 of the first side cap 10 is It may be provided such that the first and second solar cell panels 400 and 400 ′ are electrically connected to each other by being bound to the terminal unit 130 .

That is, the aforementioned binding protrusion 120 formed on the first terminal part 110 of the first side cap 10 is inserted into the binding groove 140 formed on the second terminal part 130 of the second side cap 10 ′. It may be mounted so that the first and second solar cell panels 400 and 400 ′ are electrically connected.

More specifically, when the plurality of side caps are slide-inserted and mounted on the frame in a vertical direction and connected in series, the first terminal part 110 of the first side cap 10 at the lower part and the second side cap at the upper part In the second terminal part 130 of (10'), the first terminal part 110 and the second terminal part 130 may be electrically connected by the first and second connection parts 250 and 270 formed on each side cap. .

Here, the first electrode part 250a of the first side cap 10 is configured to electrically connect the first electrode of the first solar cell panel inserted into the first insertion hole 220 to the first terminal part 110 . and the second electrode part 270a of the second side cap 10 ′ can electrically connect the second electrode of the second solar cell panel inserted into the second insertion hole 230 to the second terminal part 130 . Therefore, the first electrode of the first solar cell panel mounted on the first side cap 10 is electrically connected to the second electrode of the second solar cell panel of the second side cap 10 ′.

Therefore, it is possible to more easily connect the solar cell panels in series by the above configuration.

In addition, the photovoltaic device 20 includes a glass portion 21 to prevent the attachment of contaminants and impact to the plurality of solar cell panels.

The glass portion 21 forms the front exterior of the photovoltaic device 20 (also referred to as a 'front glass portion') and may be disposed to isolate the solar cell panel from the outside.

More specifically, the glass portion 21 may be disposed to transmit sunlight to the plurality of solar cell panels, and may be provided to surround the plurality of solar cell panels.

The glass portion 21 may be fixed by being fitted to the glass portion support member 330 provided in the frame 300 to support the glass portion.

Therefore, the present invention configures a glass portion to prevent contaminants and impacts from being attached to the solar cell panel exposed to the outside, and solar cell panels do not require tempered glass to prevent internal and external impacts and contamination inserted into each solar cell panel. There is an effect that can provide a power generation device.
