PVT T Hybrid Solar Panel

Overview

The PVT-T Hybrid Solar Panel is an advanced photovoltaic-thermal (PVT) twin-energy solution designed for modern sustainable architecture. It seamlessly integrates solar photovoltaic and solar thermal technologies into one compact module, providing high-efficiency energy output in both electricity and heat. With a total solar energy utilization rate of up to 80%, this system is optimized for applications requiring reliable electric-thermal co-generation, such as domestic hot water, space heating, and hybrid pump systems in low-carbon buildings.

Key Features

1. Dual-Energy Output (PV + Thermal)
The PVT-T module combines photovoltaic cells with thermal collectors in a single structure. While photovoltaic cells convert solar radiation into electricity, the attached thermal collector simultaneously captures residual heat from the panel surface. This integration keeps the panel's operating temperature below 55°C, reducing PV degradation and boosting both electricity output and thermal efficiency. The result is a total energy utilization rate of up to 80%.

2. Vacuum Laminated Heat Transfer Enhancement
The module adopts vacuum lamination bonding between the PV layer and the heat absorber. This design minimizes thermal contact resistance at the interface and improves heat transfer efficiency by over 40%, compared to traditional non-bonded PVT modules.

3. Three-Dimensional Insulation Structure
The front side of the panel is covered with a high-transmittance glass plate, precisely spaced to minimize convective and radiative losses. The rear side features high-density insulation materials and a long-wave high-reflectivity membrane, reducing frontal heat loss by 70% and ensuring thermal stability under wide ambient temperature fluctuations.

4. Smart Monitoring and Energy Management Integration
Equipped with embedded temperature sensors and an intelligent controller, the module can be seamlessly integrated with a Building Energy Management System (BEMS). It supports real-time thermal output adjustment based on demand, reducing system-level O&M costs by more than 35%.

Application Scenarios

· Commercial and residential domestic hot water systems

· Swimming pool heating for hotels, spas, and sports centers

· Seasonal space heating with hybrid pump and buffer tank integration

· Solar-assisted geothermal or district heating support

Core Technology Highlights

1. High-Efficiency Solar Cells
Featuring monocrystalline N-type TOPCon solar cells with multi-busbar architecture, the module delivers high power conversion efficiency, low temperature coefficient, and long-term performance stability.

2. Uniform Heat Transfer Design
The thermal collector adopts a uniform temperature distribution design. By utilizing a high-purity aluminum heat conduction substrate and optimized internal channel layout, the system maintains surface temperature uniformity within ±1°C. This enhances both PV output and thermal absorption.

3. Low-Loss Front Cover System
A high-transparency tempered glass front cover minimizes incident light reflection and heat loss. The cover is carefully spaced from the module surface to reduce thermal convection and improve insulation.

4. Robust & Durable Structure
The module frame is constructed from anodized 6063-T5 aluminum alloy, with a tensile strength of up to 180 MPa. It is sealed with UV-resistant high-durability silicone sealant, achieving IP65 waterproof rating for outdoor resilience and longevity.
