Jinan Yanyang Junior High School Solar Centralised Hot Water Project, Shandong

With China's “dual carbon” goals driving sustainable development, schools and other public institutions are paying increasing attention to energy-saving and eco-friendly solutions. As places with high population density, schools have a significant daily demand for hot water. Traditional coal, gas, or electric heating systems consume large amounts of energy, incur high operating costs, and create emissions, making them less suitable for today's green development needs.

Against this backdrop, Jinan Yanyang Junior High School in Shandong partnered with Soletks Group to implement an advanced solar centralised hot water project. This initiative not only provides abundant hot water for daily use but also demonstrates the value of clean energy in creating a healthier, more sustainable learning environment.

Project Overview

The project is located on the campus of Jinan Yanyang Junior High School. Based on the school’s actual water demand, site conditions, and local climate, Soletks Group designed a customised solar hot water solution.

The system uses high-performance flat-plate solar collectors, combined with smart control units and large-capacity storage tanks. It captures and converts solar energy during sunny hours and stores it to ensure a continuous supply of hot water even at night or on cloudy days.

Once operational, the project delivers up to 150 tonnes of hot water per day, fully meeting the needs of students and staff in cafeterias, dormitories, and shower facilities.

Technical Features

High Efficiency and Stability – Advanced flat-plate collectors provide high absorption and reliable performance even in average sunlight conditions.

Smart Control – Automated monitoring adjusts operations based on weather and usage, ensuring continuous supply with minimal human intervention.

Heat Storage – Large tanks act as “thermal batteries,” storing energy for use during cloudy days and evenings.

Eco-Friendly – No coal or gas is required, and the system produces no waste gas, water, or noise.

Cost-Effective – Operating costs are far lower than traditional heating systems, offering long-term financial benefits.

Results and Benefits

Since completion, the project has greatly improved campus living standards. Hot water is consistently available during peak demand, and students and staff no longer worry about shortages. The system also reduces annual energy expenses significantly and cuts large amounts of CO₂ emissions, delivering both economic and environmental benefits.

Wider Impact

The project is more than just a heating system; it is a model for green campus development. It proves that solar clean thermal energy can be applied effectively in schools and other public facilities, offering a practical solution for energy saving and emission reduction.

Its success provides a valuable reference for similar institutions across Jinan, Shandong, and beyond, encouraging broader adoption of renewable energy in education and public service sectors.

Looking Ahead

Soletks Group will continue to expand its expertise in clean energy applications, developing tailored solutions for schools, hospitals, factories, and other scenarios. By integrating solar thermal energy with smart control, storage, and distributed systems, the Group aims to accelerate the transition to low-carbon, sustainable energy.

The Jinan Yanyang Junior High School solar hot water project not only improves the daily lives of students and staff but also embodies Soletks's mission: “to enhance human life with clean energy.” It represents a tangible step toward a greener future and contributes meaningfully to China’s carbon peak and carbon neutrality goals.
