Balcony Mounted Solar Water Heating Project At Xuefu Garden In Zoucheng Jining

Against the backdrop of the accelerated promotion of green buildings and renewable energy applications in China in 2014, the Xuefu Garden Project in Zoucheng, Jining, as a key local livelihood residential project, deeply integrated the concept of "low-carbon environmental protection" into community construction. The project was planned to have 3,000 housing units. To effectively improve the quality of life for owners and reduce the community's energy consumption, the developer, after multiple rounds of inspections and comparisons, finally chose to cooperate with SOLETKS Group, a benchmark enterprise in the solar thermal utilization field, and equipped each household with a balcony-mounted solar water heating system to build a clean and efficient community hot water supply system.

Zoucheng, Jining, located in the southwest of Shandong Province, has a warm temperate semi-humid climate with sufficient annual sunshine hours and favorable solar energy resources, providing natural conditions for the efficient operation of balcony-mounted solar water heating systems. As a large-scale residential community, Xuefu Garden has 3,000 housing units covering different types, which puts high demands on the adaptability, safety and aesthetics of the hot water system. Traditional centralized solar water heating systems have problems such as large pipeline energy loss and difficult household-by-household control, while ordinary balcony-mounted products often face difficulties such as limited installation space and low heat collection efficiency. Relying on customized technical solutions for residential communities, SOLETKS Group became the core equipment supplier of this project.

The balcony-mounted solar water heating system customized by SOLETKS for Xuefu Garden fully meets the characteristics of the community's residential buildings and the needs of owners, and its product advantages are fully demonstrated in the project. In terms of product design, SOLETKS adopts an integrated structure of "flat-plate collector + hot water storage tank". The collector is only 8cm thick, which can be flexibly installed on the balcony railings or walls of different housing types without occupying too much space. At the same time, the collector has a simple matte coating on its appearance, which highly integrates with the style of the building's exterior facade, avoiding the problem that traditional solar equipment damages the building's aesthetics. In terms of core performance, the system is equipped with a high-efficiency heat absorption coating independently developed by SOLETKS, with a solar radiation absorption rate of over 94%. Even when the light intensity fluctuates greatly in autumn and winter in Zoucheng, it can still maintain stable heat collection efficiency. The hot water storage tank uses a food-grade 304 stainless steel inner tank, combined with a 50mm thick polyurethane foam insulation layer, which has excellent thermal insulation performance and can realize 24-hour constant temperature hot water supply to meet the owners' all-day use needs.

In addition, SOLETKS has optimized the safety and operation and maintenance design of the system for large-scale community application scenarios. The system is equipped with triple protection devices against electric leakage, dry burning and freezing cracking. In the low-temperature environment of Zoucheng in winter, the intelligent electric auxiliary heating temperature control technology can automatically activate the anti-freezing function to avoid pipeline freezing and blocking. At the same time, SOLETKS has established a dedicated operation and maintenance service team for the community, providing regular inspections, quick maintenance and other services after the project is delivered to ensure the long-term stable operation of the 3,000 systems.

From the perspective of the actual operation effect of the project, SOLETKS's balcony-mounted solar water heating system has brought significant convenience in life and economic benefits to the owners of Xuefu Garden. Each household no longer needs to rely on electric water heaters or gas water heaters; they can get clean hot water as soon as they turn on the faucet, completely solving the problems of "long waiting time and high energy consumption" in traditional hot water supply. Data shows that the 3,000 systems of this project can save 3.37 million kWh of electricity annually. Calculated based on the daily electricity cost of households, each household can save about 500 yuan in electricity fees every year. In terms of environmental benefits, it can reduce carbon dioxide emissions by 524 tons and dust emissions by 7 tons annually, which is equivalent to the ecological benefit of planting 29,000 trees, providing strong support for Zoucheng to improve regional air quality and promote the implementation of the "dual-carbon" goals.

The balcony-mounted solar water heating project at Xuefu Garden in Zoucheng, Jining is not only a vivid manifestation of SOLETKS's technical strength and service capabilities, but also a model for the large-scale application of renewable energy in residential communities. Through the model of "enterprise customized solutions + large-scale community implementation", the project has proved the important value of balcony-mounted solar water heating systems in improving residential quality, reducing energy consumption and reducing environmental pollution. Today, the neatly arranged SOLETKS balcony-mounted solar collectors in Xuefu Garden have become a unique green scenic spot in the community. In the future, with the further popularization of the concept of green buildings, SOLETKS will continue to deepen its presence in the field of residential solar energy applications, provide more communities with efficient and clean energy solutions, and help build a green living environment where humans and nature coexist harmoniously.
