Technical field
The present invention relates to photovoltaic technology field, and in particular to the applicable floating body multi-functional integrated type water surface photovoltaic of extremely frigid zones
Support system.
Background technique
Solar energy has many advantages, such as resourceful, widely distributed, renewable, pollution-free, is the clean energy resource of ideals of human being,
Significant contribution is made that building low-carbon society, there is critical role in long-term energy strategy.Photovoltaic power generation city in recent years
Field development is very swift and violent, but the limiting factor of land resource is more significant, has become what land photovoltaic plant was built energetically
Bottleneck.And water surface floating power station is as a kind of novel photovoltaic power station form, using certain floating body support construction by photovoltaic module
Swim on the water surface and generate electricity, it is a large amount of while save land resource, be also equipped with reduce water evaporation, inhibit algae reproduction,
The advantages that improving generating efficiency, effectively component and cable cooled down.China's water resource is abundant, and lake, reservoir are numerous, drift
The construction of floating water surface photovoltaic is to the Optimum utilization of resource, can widen photovoltaic application, has obtained very big concern in recent years
Development energetically.
Domestic and international common floating body support platform mainly includes two kinds of patterns at present: full floating body pattern and floating body add support rack type
