A retaining clip configured to secure an elongate member to a generally planar panel is described herein. The retaining clip includes a first side wall, a second side wall opposite the first side wall, and an end wall interconnecting the side walls. The side walls define a gap configured to receive the panel. The retaining clip includes further includes a resilient first cantilevered prong projecting into the gap from the first side wall and a resilient second cantilevered prong projecting from into the first gap from the second side wall. Free ends of the first and second prongs are characterized as having a pair of pointed barbs on distal edges of the first and second prongs. The pointed barbs are configured to increase a removal force required to remove the panel from the first gap. A method of forming such a retaining clip is also described.

This embodiment discloses a photovoltaic module unit and a photovoltaic device. The photovoltaic module unit includes: a support frame, whose side face is provided with a lapping portion; a photovoltaic module, two ends of which are lapped at the lapping portion; and load-bearing glass, bottom faces at two ends of the load-bearing glass being fixed to a top of the support frame. A preset clearance is provided between the load-bearing glass and the photovoltaic module. In the photovoltaic module unit and the photovoltaic device provided by this embodiment, the support frame is arranged to be supported on a road surface and to support the photovoltaic module, and the load-bearing glass is arranged to protect and cover the photovoltaic module. The ground photovoltaic power generation module unit and the ground photovoltaic power generation module are low in installation cost, convenient for maintenance and time-saving, and can be installed in different roadbed conditions. The photovoltaic module may adopt a high-quality CIGS module. The ground photovoltaic power generation module unit and the ground photovoltaic power generation module are higher in power generation efficiency and shorter in cost recovery time and saving in land utilization, etc.

[Problem] To provide a high-shelf hydroponic cultivation system equipped with a solar panel having a large power generation amount while ensuring light quantity for a plant. [Solution] Since the high-shelf hydroponic cultivation system 80 equipped with a solar panel has a light transmitting region A provided at the solar panel 50, more light can be taken into the frame unit and can be utilized for cultivating the plants P1 and P2. Since the double-sided light receiving solar cell 52 is employed for the solar panel 50 and light reflectivity is given to the floating bench 34, the weed-proof sheet 56, the vertical frame 20b and the like, light which does not shine on the plants P1 and P2 is reflected to a light receiving region on a rear face side of the double-sided light receiving solar cell 52 and can be effectively utilized for power generation. Thus, a large power generation amount can be obtained while ensuring light quantity for the plants.
