I. Product Introduction

580W PVT Solar Thermal Hybrid Panel | PVT Solar Thermal Panel - High-efficiency Lamination Technology, Integrated Photothermal and Photovoltaic, Targeting the European Market

The 580W PVT Solar Thermal Hybrid Panel (PVT Solar Thermal Panel) is a revolutionary hybrid energy solution that combines photovoltaic power generation with solar thermal collection in the same module, achieving dual energy output of photovoltaic and solar thermal. This product is specifically designed for the European market and perfectly suits the residential and commercial project requirements of countries with rapid development of the PVT industry, such as Germany, Switzerland, the Netherlands, and Spain. Through advanced lamination technology (Lamination Technology), the PV cells and heat exchange backsheet are formed as a single unit under pressure, combined with an integrated flow channel design, fundamentally solving the problems of hidden cracks, delamination, and short lifespan of traditional PVT components caused by the difference in thermal expansion coefficients of different materials. This product can be widely applied in scenarios such as villas, apartments, hospitals, schools, swimming pools, hotels, etc., providing users with dual benefits of clean electricity and domestic hot water.

III. Working Principle

The PVT solar panel operates based on the integrated principle of photovoltaic power generation and photothermal recovery: Sunlight is incident on the surface of the single-crystal silicon battery, and approximately 20-23% of the solar radiation is converted into electrical energy output; the remaining 70-80% of the sun's radiation heat, which should have been dissipated, is efficiently absorbed by the heat exchange medium (water or glycol solution) in the integrated flow channel on the backplate, and converted into usable thermal energy. 

This dual-energy output design provides PV cells with unique thermal management advantages: The heat exchange medium continuously removes the high temperatures generated by the cell's operation, keeping the cell running within a lower temperature range and thereby increasing the electrical conversion efficiency by approximately 10-15%. At the same time, the heat exchange medium is heated to 35-75°C and can be directly used for domestic hot water, floor heating, or pool heating, etc. A single panel can simultaneously output 580W of electricity and a maximum of 1180W of heat power, with an overall energy utilization rate of up to 70%-88%. 

IV. Product Advantages

1. Advanced laminating technology, zero cracks, long lifespan

Using high-temperature lamination technology, the PV cells and heat exchange backsheet are formed under vacuum conditions in a single pressurization process. This completely solves the problems of hidden cracks and detachment of photovoltaic silicon wafers caused by the difference in thermal expansion coefficients of different materials in traditional processes. Research shows that by optimizing the lamination temperature (145℃) and duration (780-900 seconds), a high peel strength of 50-80 N/cm and an average crosslinking degree of 70.95% can be achieved. This ensures the stability of the module operation within a wide temperature range of -40℃ to 85℃, with a lifespan of up to 25 years. 

2. Dual-energy output, saving 40% of roof space

Integrated photovoltaic and solar thermal design, one panel can generate electricity and heat simultaneously. Compared to installing two separate systems of photovoltaic and solar thermal separately, this design can save approximately 40% of installation area, significantly reducing the roof load requirements and installation costs. 

Intelligent thermal management, with an increase in electrical efficiency of 10-15%

The heat exchange backplate actively absorbs the waste heat from the battery, keeping the PV cells always within the optimal working temperature range. The electrical conversion efficiency is improved by 10-15% compared to conventional photovoltaic modules. The peak power of the thermal energy recovery reaches up to 1180W, achieving efficient hierarchical utilization of energy. 

3. All-copper tube plate heat exchanger, highly efficient and durable

It adopts a tube plate type all-copper heat exchange structure, with excellent heat conduction performance, a pressure resistance of 0.6 MPa, corrosion resistance and anti-scaling properties. Combined with the integrated full-flow channel design, the heat exchange area is maximized, ensuring that the thermal energy recovery efficiency always remains at the industry-leading level. 

4. International certification, TUV/CE compliance

The product has passed the TUV 1500V system voltage test and complies with international standards such as CE and Solar Keymark. It provides complete compliance document support for customers to enter the European market. 

5. Four seasons of energy efficiency, short investment payback period

Stable power generation and heat production throughout the year, saving over 60% of electricity and fuel costs annually; large-scale heat collection combined with propylene glycol antifreeze can provide a stable heat source all day long. The investment payback period is usually only 3-5 years. 

6. High installation efficiency, low transportation cost

Single-piece lightweight design (39kg), one 40-foot container can carry 427 sets, significantly reducing cross-border logistics costs and ensuring stable and efficient batch supply.
