Bosch Solar Collectors
Solar 8000 TF top flat plate
FS 226-2V
Bosch new generation solar collector with full sheet molding compound cover (SMC technology)，high selective coating PVD full sheet absorber, instantaneous efficiency 82.4% and win the Solar Keymark certificate.
Bosch new generation solar collector with full sheet molding compound cover (SMC technology), high selective coating PVD full sheet absorber, instantaneous efficiency 82.4% and win the Solar Keymark certificate.
- Larger collector area: 2.55m2 size to have more solar energy output
- Ω Omega ultrasonic welding for perfect heat transfer; combines the robustness of ultrasonic welding with invisible welding lines
- Glass and absorber sealing with filling of inert gas, reduce heat loss greatly
- Absorber SKT Al/Cu full sheet with PVD coating, without welding stripes
- Double meanders flow design, quick heating with high temperature rising
- One-piece casing based on SMC technology (sheet molding compound)
- Design high-value optic due to new casing, Brand specific stampings of absorber

Collector with outstanding performance:
- Excellent high selective PVD coating ensures the high efficiency of collector
- Omega ultrasonic welding with more bigger contact area and therefore better heat transfer
- Lower iron solar safety glass with high light penetration, more solar energy reaches to the absorber
- Glass and absorber sealing with filling of inert gas, reduce heat loss greatly
- Low solar liquid volume design to ensure quick heating, lower pressure loss and higher temperature rising
- Double meander flow structure design to easily drain the collector and resist the high stagnation temperature
- One-piece casing based on SMC technology (sheet molding compound) with transport hand grips for better handling
Easily installing and design the collector field:
- Double meander flow structure design, reducing the pressure loss, when inlet/outlet both sides arranging, 10 collectors can be series connected, when inlet/outlet one side arranging, 5 collectors can be series connected
- One piece glass fiber frame design, to reduce the weight of collector for easily moving and installing
- Quick insert stainless steel connection between collectors, easy installation with only one tool
- Larger collector area 2.55m2, for same volume tank, higher temperature can be expected
- Complete accessories for flat roof, integration, on roof, facade installation
