EFPC Solar collector provides a new paradigm for heating supply

BTE Solar held a seminar titled "Research and Application of Ultra-Large Flat-Plate Collectors in Solar District Heating," providing an in-depth analysis of the company's core technological breakthroughs. This collector utilizes a proprietary blue-film heat-absorbing coating and, through precision manufacturing, achieves a leading instantaneous efficiency of 0.81 and a primary heat loss as low as 2.27. In urban centralized heating and building hot water supply scenarios, it demonstrates economic efficiency and reliability far exceeding that of traditional equipment. Recognized for its exceptional performance, BTE Solar's EFPC high-efficiency integrated ultra large flat plate collector was awarded the Shandong Provincial Science and Technology Award. This honor not only represents authoritative recognition of technological innovation but also marks the company as a new benchmark in solar district heating and high-quality hot water.
