- the double-sided photovoltaic panel is supported on the top of the support member, and the support member may be a building member such as a bracket or a pillar.
- a top condenser lens (not shown) can be further mounted over the double-sided photovoltaic panel.
- the concentrating cover plate of the surface solar system of the present embodiment is laid on the auditorium of the stadium, and the concentrating module can adopt the structure shown in FIGS. 4(b) to (e). Since the laying area is large, the pattern shown in Fig. 1 (b) or (c) can be selected.
- the system arrangement of this embodiment is also suitable for laying other large-area solar energy systems, for example, a large-area solar system that can be used for laying emergency lanes on the road, water surface (artificial island), etc.
- the overall shape of the concentrating and surfacing panels can be along with the laying site. The change is varied. When used in an application scenario requiring a large load capacity, the concentrating module shown in FIG. 4(e) can be preferably used.
- the temperature controller 323 may be included in the system, so that the solar system of the embodiment has certain anti-snow and anti-ice capabilities.
- the energy storage device 315, the AC inverter 316, the network switch cabinet 317, the external AC power grid 318 AC power distribution board 319, and the status indicator 321 can refer to Embodiment 1, no longer. Narration.
- the embodiments of the present invention have been described with reference to the specific embodiments of the present invention. It is understood that the above embodiments are only used to help the understanding of the present invention and are not to be construed as limiting the invention. Variations to the above-described embodiments may be made in accordance with the teachings of the present invention. For example, if the reflecting surface in the above embodiment is disposed on a roof, a ground, a road surface, a water surface, or a window, the corresponding solar energy system becomes a solar roof, a ground/road solar system, a solar artificial island, and a solar window.
