Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic support technical field, concretely is a water surface photovoltaic support. BACKGROUND

[0002] Photovoltaic power generation is a technology that converts sunlight directly into electricity, which is based on the photovoltaic effect of semiconductor materials. When sunlight shines on a solar cell (usually made of semiconductor materials such as silicon), the photon energy is absorbed by the electrons in the semiconductor, allowing the electrons to gain enough energy to transition from the valence band to the conduction band, thereby generating free electrons and hole pairs. These carriers are separated and moved under the action of the built-in electric field, forming a current, and ultimately outputting power through an external circuit. With the advancement of technology, the cost of photovoltaic power generation continues to decline, and the efficiency is constantly improving, which makes it one of the increasingly popular renewable energy solutions.

[0003] Water surface photovoltaic support is a structure specially designed for installing solar panels on water surface, which is usually divided into floating type and fixed type water photovoltaic support. The fixed type water photovoltaic support is a structure installed above the water surface but not floating, which is fixed to the water bottom through pile foundation or support column, so that the photovoltaic panel is kept at a certain height above the water surface. This type of system is usually used in reservoirs, lakes, ponds and other static or slow flowing water areas. The fixed type water photovoltaic support is a technical solution that combines the stability of traditional ground photovoltaic system and the space utilization advantage of floating photovoltaic system, suitable for solar power generation projects under specific geographical and environmental conditions.

[0004] The fixed type water photovoltaic support in the prior art usually does not have height adjustment function. The water level of reservoirs, lakes and other water areas will fluctuate due to seasonal changes or climate changes. If the height of the support is not adjustable, when the water level rises, the photovoltaic panel may be submerged; when the water level drops, the photovoltaic panel may be too far from the water surface, which may cause instability or increase wind resistance.
