PVT Flat Plate Solar Collector
OEM PVT Solar Collector — Manufacturing & Supply
Millionsun manufactures PVT (photovoltaic-thermal) solar collectors for distributors, solar brands, EPC contractors, and project developers worldwide.
A PVT collector combines photovoltaic cells and a thermal absorber in a single panel. The PV layer generates electricity while the thermal absorber extracts heat from the back of the panel — cooling the PV cells (improving electrical efficiency) and capturing useful heat for water heating or other applications.
Available for OEM orders. Custom configurations available for project-specific requirements.
Key Highlights
- OEM Manufacturing Support
- Private Label Production
- Combined PV + Thermal in One Panel
- Simultaneous Electricity and Heat Generation
- PV Cell Cooling Improves Electrical Output
- Suitable for Residential & Commercial Projects
- Compatible with Existing Solar Thermal Systems
Key Features & Performance
Dual Energy Generation
One panel generates electricity and heat simultaneously. PV cells produce DC electricity. The thermal absorber collects heat from the rear of the panel.
Improved PV Efficiency
Heat extraction from the back of the panel cools the PV cells. Lower cell temperature means higher electrical efficiency compared to standalone PV panels.
Space Efficient
One panel does the work of two.
Standard Flat Plate
Design Fits standard flat plate collector frames.
Aluminium Absorber Construction
Full aluminium sheet with copper tubes.
Low-Iron Tempered Glass Cover
3.2mm. Transmission ≥92%.
Aluminium Alloy Frame
Alloy 6063. Silver or black.
