Design of floating surface photovoltaic power station in the Netherlands
1. Project background and goals
As the world’s largest flower exporter, the Netherlands occupies a core position. However, due to high energy consumption (such as LED fill light, temperature control systems), traditional greenhouses account for more than 30% of operating costs. This project is located in a flower greenhouse in Gelderland, Netherlands. Due to the limitation of the greenhouse structure, photovoltaic panels cannot be installed, and land resources are scarce, so the photovoltaic system is innovatively moved to the water surface of the supporting reservoir in the greenhouse to create a comprehensive solution integrating clean energy production, water resource protection and agricultural efficiency enhancement. The goal is to achieve 100% self-sufficiency in greenhouses, reduce carbon dioxide emissions by more than 470 tons per year, and reduce irrigation costs and improve flower quality.
2. System design and technical solutions
Main structure of floating photovoltaic power station
Adopts anemone ® surface floating photovoltaic system, with core components including:
HDPE modular float: food-grade high-density polyethylene material, anti-aging and corrosion-resistant, with a design life of more than 25 years, and the modular design is convenient for rapid installation and maintenance. The floating body adopts a multi- compartment structure, with a redundant buoyancy of up to 30%, and can withstand strong winds of 50m/s (equivalent to a typhoon of 16th level).
Dual-axis tracking photovoltaic module: equipped with 73kWp double-sided power generation module that can track the sun, adjust the angle in real time through machinery and light sensors, which increases the power generation of fixed systems by 40%. The surface of the components is coated with a self-cleaning coating to reduce dust and algae adhesion and ensure efficient power generation in the long term.
Intelligent inverter and monitoring system: Deploy Vimapa MAX 80KTL3 LV inverter, with 7-channel MPPT and IP65 protection levels, adapting to complex water environments. Through the cloud platform, power generation, water quality data (such as dissolved oxygen, pH value) and equipment status are monitored in real time, and the alarm is automatically made when abnormalities are abnormal and the operating parameters are optimized.
Wind resistance and anchoring system
For the Dutch windy climate, the “east-east-to-east-to-block arrangement + flexible anchoring” solution is adopted:
Component arrangement: Each floating unit is equipped with 16 components, 8 facing east and 8 facing south, forming a “solar ship” structure that can disperse wind loads and reduce vortex effects.
Anchor design: A hybrid anchor system is adopted that combines spiral anchors and concrete gravity anchors. The length of the anchor chain is dynamically adjusted according to water level fluctuations to ensure stable operation under the 18-meter water level amplitude. Optimize the structure through 5D virtual wind tunnel simulation to reduce the wind pressure of the array edge module by 50%.
Collaborative water resources management
Evaporation inhibition and water quality improvement: The photovoltaic panels cover the water surface and reduce the evaporation volume by 42%, while reducing the water temperature by 2-3℃, inhibiting algae reproduction and improving irrigation water quality.
Rainwater collection and recycling: Set up a diversion tank on the edge of the floating body, collecting rainwater is purified and used for greenhouse irrigation. Combined with drip irrigation technology, the water consumption per unit of flower is reduced to 1/12 of the traditional method.
