High Performance Integrated Large Flat Plate Collector

The EFPC integrated large flat plate solar collector represents the latest advancement in solar thermal engineering, combining superior efficiency, innovative integration, and long-term durability. Designed with an oversized flat plate structure, it maximizes sunlight absorption, delivering powerful and stable thermal output. The product’s integrated approach—from absorber plate to insulation and controls—reduces installation complexity, lowers operational costs, and ensures easy maintenance throughout its lifecycle.

For businesses, communities, and institutions looking to transition to sustainable heating solutions, EFPC offers a compelling balance of technical performance, economic return, and environmental responsibility.

Broad Application Scenarios

1. Residential and Commercial Heating
EFPC collectors are a proven alternative to fossil fuel-based heating systems in apartments, villas, schools, hotels, and office complexes. With reliable operation even in harsh winters, the system connects seamlessly to radiators or underfloor heating networks. Combined with thermal storage tanks, it secures 24-hour heating by storing surplus energy from the day and releasing it at night. This reduces reliance on coal and gas boilers, lowers energy bills, and helps urban areas improve air quality by cutting emissions.

2. Industrial Process Heat
Industries such as textiles, food processing, chemical manufacturing, and machinery require continuous, high-temperature heat for operations like dyeing, steaming, and sterilization. EFPC delivers large-scale thermal energy with high conversion efficiency and steady output, aligning with the demands of industrial production. The adoption of EFPC reduces fuel procurement costs, cuts greenhouse gas emissions, and positions companies at the forefront of sustainable manufacturing—a growing requirement for global supply chains.

3. Agricultural and Livestock Farming
In modern livestock farming, temperature stability directly affects animal health and survival. EFPC systems provide reliable heating for barns and poultry houses, preventing losses caused by sudden cold snaps. By eliminating the need for coal or gas burners, the system maintains clean indoor air, creating a healthier environment for both animals and farm workers. For farmers, this translates into higher survival rates, improved growth conditions, and stronger economic returns, all achieved with an eco-friendly solution.

Key Advantages for Businesses

1. High Performance

   The EFPC collector achieves efficiency levels above 85%, well above global industry averages. Its large flat plate design captures 30% more solar radiation compared with traditional collectors, ensuring sufficient energy supply even under less-than-ideal sunlight conditions.

2. Integrated Design

   Pre-assembled components, including absorber plate, insulation, and control systems, reduce installation time by up to 80%. For investors and project developers, this means faster deployment, lower labor costs, and quicker project payback.

3. Durability and Reliability 

   Constructed with high-strength aluminum alloy frames and tempered glass, EFPC withstands strong winds, hail, and corrosion. With operating pressure resistance up to 16 Bar and wide temperature adaptability from -30°C to high summer heat, the system delivers long-term security for large-scale projects.

4. Low Maintenance

   Unlike traditional systems that require frequent inspections, EFPC only needs basic cleaning 1–2 times per quarter. Its core components, such as the blue film absorber and EVS flow channels, are designed for over 25 years of service life without replacement, minimizing operational overhead.

Technology Driving Value

· Blue Film Absorber: 

Multi-layer sputtering technology provides a solar absorption rate above 95% and infrared emission below 5%, maximizing conversion efficiency while minimizing heat loss.

· Finite Element Flow Channel Design: 

Precision-engineered flow channels maintain stable heat transfer even under large day-to-night temperature variations, preventing structural stress or performance loss.

· Thermal Cabin Insulation: 

Innovative insulation structure reduces heat loss coefficient to 2.2—well below the 3.5 industry average—ensuring consistent performance in climates as cold as -40°C.
