BTE Solar: A Stunning Transformation From Solar Water Heating To Flat Plate Clean Thermal Energy

Amid the resounding call of the "Dual Carbon" strategy, BTE Solar initiated a strategic transformation from "solar water heating" to "flat-plate collector clean thermal energy," successfully achieving a historic leap from "selling products" to "selling systems," and from "hot water supplier" to "thermal energy solution provider."

01 What is flat-plate collector clean thermal energy?

Flat-plate collector clean thermal energy refers to a comprehensive energy technology system that couples flat-plate solar collectors with multiple clean energy sources, such as geothermal energy and air energy, to meet the energy needs of diverse scenarios, including building energy, industrial heat, farming and breeding, drying, and new infrastructure, for high-quality thermal energy, heating, cooling, and electricity. It breaks the limitations of single energy sources and achieves efficient energy supply through multi-energy complementarity.

02 Why transition from solar water heating to "flat-plate collector clean thermal energy"?

As a renewable, pollution-free, and low-cost clean energy source, solar energy can effectively reduce dependence on traditional fossil fuels and lower pollutant emissions through its heating capacity, offering significant environmental and economic benefits. However, solar energy also has a fatal flaw: insufficient stability. It cannot provide a stable heat source in low- or no-light conditions, such as at night or during periods of continuous overcast weather. This significantly limits its application. To overcome this bottleneck and seek more reliable integrated energy solutions, the flat-panel clean thermal energy solution was developed. "This transformation is the most profound and impactful in the company's history," Chairman Han Rongtao has repeatedly emphasized in public. In the past, the application of solar water heaters was limited to daily life, such as home bathing and kitchen hot water, severely restricting the product's application scenarios. Now, through the "solar + multi-energy" system coupling technology, Shengtuo Ke has successfully expanded the application of solar energy to urban centralized heating, agricultural drying, heating for crops and livestock, and industrial high-temperature heating, achieving widespread clean thermal energy supply.

03 Flat-panel clean thermal energy has achieved initial success!

Through the tireless efforts and relentless refinement of BTE Solar's R&D team, flat-plate collector clean thermal energy technology has successfully transitioned from laboratory research and development to commercial application, with numerous benchmark projects successfully implemented: Scroll left and right to view more. The EFPC high-efficiency integrated large flat-plate solar collector district heating project: adapted to high-altitude, low-temperature environments, providing stable heating for the local area; the PV/T collector + heat pump coupled heating project: integrating solar thermal and heat pump technologies to improve heating economy, stability, and efficiency; and the DVC air collector + heat pump coupled drying project: precisely meeting the drying needs of agriculture and industry, reducing drying energy consumption and costs.

04 Technical Core: Innovation-Driven Development

BTE Solar has always regarded "innovation" as its core competitiveness and has established a robust research and innovation system. BTE Solar boasts seven R&D departments, a carbon neutrality research institute, an academician workstation, a key laboratory, and a technology center. Researchers account for 16% of BTE Solar's workforce, 50% of whom have over 20 years of industry experience and possess deep technical expertise and practical skills. BTE Solar is also actively engaged in industry-university-research collaboration, collaborating with 19 universities and research institutes, including the Chinese Academy of Sciences, Tsinghua University, and the Shandong Academy of Sciences, to overcome technical challenges. The company has secured a total of 117 patents and solutions, providing solid support for the continuous iteration and application expansion of its flat-plate collector clean thermal energy technology.

05 BTE Solar Makes Every Ray of Sunlight More Warm

As Chairman Han Rongtao said, "We're not just selling a flat-plate collector, but a gateway to a zero-carbon world." As sunlight shines down on the earth, BTE Solar is using innovation and perseverance to make every beam of light more warm. From rooftop solar water heaters to flat-plate clean thermal energy systems deployed across numerous industries, BTE Solar will continue to deepen its commitment to the flat-plate clean thermal energy sector, driving the rapid transformation of technological innovation into practical applications and contributing to the achievement of the "dual carbon" goals.
