1、 Project Introduction

The construction project of the 215kWh integrated photovoltaic storage and charging power station in the escort center is undertaken by Henan Sunshine Longrui New Energy Co., Ltd. The project is located at the northwest corner of Meihe Road and Huanghai Road in Zhengzhou City, Henan Province. As a demonstration project of the integrated digital smart park of light storage and charging, the project integrates various advanced products and technologies, aiming to play a demonstrative role and provide solid technical support for Guangtou Group's future projects in the field of new energy.

The project utilizes the rooftop space of the park to construct a photovoltaic power generation system and renovates existing parking spaces, establishing a comprehensive carport facility that integrates photovoltaic power generation, energy storage, and charging. The project design adopts a containerized structure, with each container equipped with a 215kWh energy storage cabinet, a 480kW charging host, and a 30kW MPPT. The energy storage system adopts forced air cooling technology to ensure efficient operation. In addition, the project is also equipped with one 600kW DC single gun flash charging equipment and four 250kW DC double gun overcharging equipment, as well as the supporting digital smart park management system, committed to creating an Internet based, intelligent, digital and shared smart park, and leading the development of new energy applications and smart park construction in Henan Province.

2、 Project Proposal

The system adopts an external power grid input AC-DC module and an internal DC coupling architecture. It can seamlessly integrate with API interfaces of domestic and foreign operation platforms, adapting to diverse market environments ranging from strong power grids in China to weak power grids abroad. The system can be flexibly configured according to different application scenarios, including various modules such as photovoltaics, energy storage, flash charging, and overcharging. In addition, the system also provides multiple financing options, optimizing the combination of these four modules to maximize the system's investment return.

4、 Conclusion

Against the backdrop of global energy transition and sustainable development, it is particularly important to promote the construction of integrated photovoltaic buildings. This innovative measure not only cleverly integrates solar power generation technology with building design, but also effectively improves energy efficiency and environmental friendliness of buildings without increasing additional land use. Through careful design, photovoltaic panels can become a part of the exterior of buildings, both aesthetically pleasing and practical.

Fully utilizing diverse spatial resources such as building roofs, facades, roads, and open spaces for new energy construction is an important strategy for urban sustainable development. The photovoltaic panels on roofs and facades can provide some or even all of the electricity needed by buildings, while photovoltaic facilities on roads and open spaces can power public lighting and transportation systems. These measures not only reduce dependence on fossil fuels, but also decrease greenhouse gas emissions, creating a cleaner and greener living environment for urban residents.

Integrating innovative technology into green buildings means we are moving towards a smarter and more environmentally friendly future.
