Layered Technology Redefines Integrated Photovoltaic-Thermal Systems

Hybrid Photovoltaic Thermal Collector

As the global transition to clean energy accelerates, Hybrid Photovoltaic Thermal Collector (PVT collector) is emerging as one of the most promising technological routes in the field of solar energy utilization. The PVT collector integrates photovoltaic power generation with thermal collection, generating electricity on the front side and heat on the back side, achieving a comprehensive solar energy utilization rate of over 80%. Our PVT collector, utilizing industry-leading high-temperature vacuum laminating technology, provides efficient, stable, and long-lasting clean energy solutions for hotels, hospitals, schools, and industrial settings.

I. Core Technology: Laminating Technology vs. Traditional Technology

Traditional PVT collectors often employ adhesive or mechanical pressing techniques, resulting in high thermal resistance between the photovoltaic cells and the heat exchange backsheet, prone to delamination and cracking. Our laminating technology, using high-temperature vacuum one-step lamination, integrates TOPCon photovoltaic cells with an integrated full-flow heat exchange backsheet in one step, achieving high peel strength and high crosslinking, ensuring stable operation within a -40°C to 85°C wide temperature range.

II. Product Advantages

✅ Dual-energy One Board - 70-88% Comprehensive Efficiency - Photovoltaic power generation on the front side, efficient heat collection on the back side, outputting both electricity and heat, saving 40% of roof space

✅ Active Cooling - 10-15% Power Gain - Heat exchange backsheet continuously removes battery heat, reducing operating temperature, increasing photovoltaic power generation efficiency by 10-15%

✅ Year-round COP above 5.0 - Intelligent dual-source collaboration, preventing frosting in winter and overheating in summer, saving 35%-55% energy compared to single heat source systems

✅ -40°C to 85°C Wide Temperature Range Operation - Water-based PVT design without cracking, overcoming differences in material expansion, stable operation throughout the day

✅ 25-year Long Service Life - High-temperature vacuum laminating eliminates cracking and delamination risks, component lifespan matching that of photovoltaic modules

IV. Application Cases

Case 1: Large Hotel PVT Combined Heat and Power System

A large hotel installed 320 PVT collectors to provide hot water for guest rooms, laundry rooms, and kitchens. At the same time, photovoltaic power was used to supply part of the electricity for the hotel. The overall energy utilization rate reached 78%, and the investment payback period was only 3.5 years.

Case 2: Industrial Factory Energy Saving Renovation

A factory installed 280 PVT modules, reducing energy consumption by approximately 30% throughout the year. The investment payback period was only 3 years and more. The PVT system provided a stable heat source for the factory, and the photovoltaic power was directly used for production equipment, achieving "self-generation and self-consumption, with surplus power fed back to the grid".

Case 3: Hospital PVT Hot Water + Heating System

A hospital adopted a PVT collector array to provide 24-hour constant temperature hot water and winter heating for the inpatient department, operating room, and staff dormitories. The system was equipped with a large-capacity water tank, achieving a comprehensive energy-saving rate of 65% throughout the year. The operation emissions were close to zero, making it a benchmark project for green transformation in the medical system.

V. Common FAQs

Q1: What are the differences between PVT collectors and ordinary photovoltaic panels?

PVT collectors generate electricity while also recovering waste heat, with a comprehensive efficiency of 70-88%, while ordinary photovoltaic panels only generate electricity, with a comprehensive efficiency of approximately 20%, and PVT can save 40% of roof space.

Q2: How does the laminated process affect the system's lifespan?

The high-temperature vacuum laminating process realizes the integrated molding of photovoltaic cells and heat exchange back plates, eliminating risks of cracks and delamination, and the component lifespan exceeds 25 years, the same as that of photovoltaic components.

Q3: Can the system meet both hot water and heating needs simultaneously?

OK. The PVT collector converts the waste heat from photovoltaic power generation into domestic hot water or heating energy through the combined heat and power mode, achieving a one-stop supply of "power generation + hot water + heating".

Q4: Does it support OEM customization?

Yes. Component size, water tank capacity (100L - 300L and larger), and appearance color can all be customized as per customer requirements. It also supports customer brands/LOGOs.

Q5: How long is the investment payback period?

As an example for industrial projects, the investment payback period is approximately 3-4 years. For civilian and commercial projects, the initial installation cost can generally be recovered within 3-5 years depending on local energy prices.
