Black Flat Plate Solar Collector
Millionsun specializes in OEM and ODM manufacturing of black flat plate solar collectors for distributors, solar water heating brands, EPC contractors, and installation companies worldwide.
Key Component & Performance
Black Selective Coating
High absorptivity (95%±2%) & low emissivity (8%±2%) for high-efficiency energy capture and low heat loss.
3.2 mm Low-Iron Tempered Glass
≥92% light transmittance, impact-resistant and weather-proof.
Full-Copper Flow Channels
Custom size options, delivering reliable heat transfer and anti-corrosion performance.
Aluminium / Copper Absorber Optional
Black selective-coated absorbers; ultrasonic or laser welding for superior thermal contact.
6063 Aluminium Alloy Frame
Multiple colour options, anti-corrosion treatment, ideal for building integration.
Glass Wool Insulation
35 kg/m³ density, reduces back and side heat loss effectively.
EPDM / Silicone Sealing
Weather-resistant sealing against moisture and dust ingress.
