Technical Parameters of the ML 450/1200 PVT Module
The ML 450/1200 PVT module is a hybrid solar panel that simultaneously generates electricity and thermal energy. This module boasts high electrical efficiency thanks to its multi-busbar monocrystalline cells. This module can be considered a high-performance product. Its efficiency is 20.7%, which stands out beyond electrical efficiency of many typical PVT modules. The overall efficiency and thermal output are comparable to standard market solutions in PVT technology.
Electrical efficiency: This model boasts a PV efficiency of approximately 20.7%. Typical PVT modules typically have electrical efficiencies ranging from 8% to 12%, or slightly higher in demanding applications. This relatively high efficiency of approximately 20.7% is achieved thanks to high-efficiency monocrystalline cells and multi-busbar technology.
Thermal power: The module delivers 1218 Watts of heating power from a surface area of approximately 2.16 m², corresponding to a thermal efficiency of approximately 56-65%.
Total efficiency: For PVT systems, this is the sum of the electrical and thermal efficiencies, typically ranging from 65% to 76%. Considering the electrical and thermal power values listed above, the PVT ML 450/1200 model exceeds commercially available PVT modules in this respect.
Temperature coefficients*: They are consistent with comparative testing: a degradation of electrical power of approximately 0.36%/°C is typical, and a degradation of thermal efficiency of approximately 0.33%/°C is also within expected standards.
*Temperature coefficients indicate the reduction in electrical and thermal power due to temperature changes.
Power Output (PV) – 450 Wp: This is the maximum power output that photovoltaic cells can produce under standard test conditions (STC). This parameter determines the power of the module’s photovoltaic component.
Heat Output 1218 Wt: The module’s thermal component can produce up to 1218 watts of thermal energy.
Copper-Aluminum Harp Heat Exchanger: The thermal absorber utilizes copper tubes, which conduct heat perfectly, improving the module’s thermal efficiency. Omega technology combines the absorber harp with aluminum strips that capture solar heat.
