EFPC Flat Plate Collector Pro Max

Product Introduction

As an advanced solar thermal collector technology, the high-efficiency integrated large flat plate collector has become a crucial component in district heating systems due to its high efficiency, stability, and scalability. Compared to traditional energy heating systems, this innovative solution not only significantly reduces fossil fuel consumption and greenhouse gas emissions but also effectively lowers operational costs, achieving a win-win in economic and environmental benefits. Each unit features a profiled light-receiving area of up to 15㎡. Remarkably, it maintains over 55% output efficiency even in harsh environments with temperature differences exceeding 70℃ between working and ambient conditions. This makes it ideal for clean heating and district heating projects in high-altitude and high-latitude regions, reducing initial investment costs by over 30%, lowering operational expenses by more than 60% compared to coal-fired heating, and cutting carbon emissions by over 70%. Operating at 90℃, the system delivers stable thermal output with over 45% solar-to-thermal conversion efficiency. It is widely applicable in industrial and agricultural heat applications, including textile dyeing, industrial preheating, copper mining cleaning processes, and agricultural product processing disinfection procedures.

Since 2020, in China's Xizang, Qinghai, Xinjiang and other western regions, the efficient integration of large flat plate collector district heating projects has been gradually promoted and applied.

Special Introduction: EFPC 150 High Efficiency Integrated Large Flat Plate Collector

The EFPC 150 high-efficiency integrated large flat plate collector, with a single-unit area of up to 15㎡, surpasses the previously awarded "highest efficiency level certificate" for the EFPC115 large flat plate collector. The nearly 4㎡ increase makes it stand out as a true "super large flat plate." In the regional heating project of Saga County, Shigatse City, the high-efficiency integrated large flat plate collector has demonstrated its capabilities, providing high-quality clean thermal energy for over 100,000 square meters of buildings. This successful case even attracted the attention of the , which highly praised its heating efficiency, economic performance, and environmental friendliness. Meanwhile, the contributions of SOLETKS Group in promoting the construction of the ecological security barrier have also been fully recognized.

In the Ali region, the EFPC 150 high-efficiency integrated large flat plate collector has been widely adopted. This collector utilizes the company's proprietary membrane material, featuring controllable quality and exceptional performance. Rigorously tested by national laboratories, it achieves a thermal efficiency of 81.3%. Even in harsh high-altitude and cold environments, it maintains efficient heat collection with stable performance. Research data indicates that this super large flat plate system reduces land use by over 50%, cuts pipeline and accessory usage by more than 50%, and shortens installation time by 80%. The crane-lift installation method also significantly reduces workers' labor intensity and enhances installation efficiency.
