Against the backdrop of accelerating global energy transition, ground mounted solar power stations have become a key force in promoting the development of renewable energy. PWSOLAR, with its outstanding technical strength and rich project experience, successfully installed and operated a 15 MW solar utility ground power plant project in Germany in 2021. This project adopts advanced 415 watt single-sided solar panels, setting a new benchmark for the development of green energy in Germany and even globally.
Project Background and Significance
As a pioneer in the global energy transition, Germany has been committed to increasing the proportion of renewable energy in the energy structure. In recent years, the German government has provided a series of policy support to encourage the construction of ground power stations for solar energy public utilities, in order to address climate change and energy security challenges. PWSOLAR actively responded to this call and launched a 15 MW solar utility ground power plant project in Germany in 2021, aiming to provide clean and reliable electricity supply to Germany while promoting the global energy transition process.
Project Technical Proposal
Selection of Photovoltaic Modules
This project adopts 415 watt single-sided solar panels, which have the following advantages:
High efficiency: Single sided solar panels achieve higher photoelectric conversion efficiency and effectively increase power generation by optimizing battery structure and materials.
Reliability: The single-sided design reduces the complex structure of the battery surface, lowers the failure rate, and improves the stability of the system.
Cost effectiveness: The production cost of single-sided solar panels is relatively low, which helps to reduce the overall investment cost of the project.
Environmental adaptability: Single sided solar panels can maintain good performance under various climatic conditions, adapting to the changing climate environment in Germany.
System Design
This project adopts a "full online" electricity sales model, and the system design is as follows:
Photovoltaic array: Adopting a fixed bracket installation method, the layout is optimized according to local terrain and lighting conditions to ensure maximum power generation efficiency.
Inverter: Select string inverters to achieve efficient energy conversion and grid control.
Grid connected system: equipped with smart meters and monitoring systems, real-time monitoring of system operation status and power generation to ensure stable power output.
Energy storage system: According to project requirements, energy storage equipment can be configured to balance grid fluctuations and improve the reliability of power supply.
Project Implementation Process
Project evaluation: Conduct on-site investigation, evaluate terrain, lighting conditions, power grid access points, etc., to ensure the feasibility of the project.
Scheme design: Based on the evaluation results, develop a detailed design scheme, including photovoltaic array layout, equipment selection, construction plan, etc.
Equipment procurement: Select high-quality suppliers to purchase photovoltaic modules, inverters, brackets, and other equipment to ensure equipment quality and performance.
Construction and installation: A professional team carries out construction and installation to ensure project quality and safety.
Grid connection acceptance: Complete the grid connection procedures, pass the acceptance of the German power grid company, and ensure the compliant operation of the project.
Operation and maintenance services: Provide long-term operation and maintenance services, including regular inspections, equipment maintenance, troubleshooting, etc., to ensure the long-term stable operation of the system.
Economic Benefit Analysis of the Project
investment cost
The total investment of this project is about 60 million RMB, and the specific composition is as follows:
Photovoltaic modules: approximately 30 million RMB
Inverter and electrical equipment: approximately RMB 15 million
Installation project: approximately 10 million RMB
Other expenses: approximately 5 million RMB
Revenue Analysis
The expected annual power generation of this project is approximately 18 million kilowatt hours, and the revenue will be calculated based on the following electricity prices:
Full on grid electricity price: According to the German Renewable Energy Law (EEG), this project enjoys a fixed electricity price subsidy, with an electricity price of approximately 0.08 euros per kilowatt hour (approximately 0.6 RMB per kilowatt hour).
Annual revenue: 18 million kilowatt hours x 0.6 yuan/kilowatt hour=10.8 million RMB
Investment payback period: approximately 5.56 years
Energy saving and emission reduction benefits
This project saves about 7200 tons of standard coal annually, reduces carbon dioxide emissions by about 18000 tons, reduces sulfur dioxide emissions by about 540 tons, and reduces nitrogen oxide emissions by about 270 tons.
Policy Support
This project complies with the German Renewable Energy Law (EEG) and multiple EU policy supports:
The German Renewable Energy Law (EEG) provides fixed electricity price subsidies and priority grid connection rights for renewable energy projects.
The EU Renewable Energy Directive requires member states to increase the proportion of renewable energy in the energy structure and provide policy support for projects.
Local subsidy policy: Depending on the location of the project, additional subsidies or tax incentives may be enjoyed.
Project Advantages
Efficient and energy-saving: Using 415 watt single-sided solar panels, the power generation efficiency is high, effectively increasing the amount of electricity generated.
Fast investment return: The investment can be recovered in 5-6 years, and the following ten years are the pure income period.
Significant environmental benefits: reducing carbon emissions, improving environmental quality, and meeting global sustainable development goals.
Policy support: Enjoying multiple subsidies and tax incentives from Germany and the European Union, reducing project risks.
Enhancing corporate image: As a green energy project, PWSOLAR has improved its brand image and market competitiveness.
