Hybrid photovoltaic / thermal panels

Advantages

• Higher energy yield per surface area
• Reduced manufacturing and installation cost
• Reduced payback time

Advantages of the silicone gel lamination for PV/T panel design

• Reduced thermal resistance (insulation) between PV cells and the heat exchanger due to direct lamination technology (I.e. improved cooling of PV cells and increased thermal energy yield)
• High operation temperature limit  (+260oC) of silicone gel enables to survive  thermal accidents (up to +150oC by glazed PV/T panels) which can destroy EVA laminate (temp.limit +85oC)
• Unlike EVA the silicone gel compensates BOTH surface deformations (imperfections) AND thermal expansion differences between PV cells and the heat exchanger (cooling profile)
• Unlike EVA encapsulant the silicone gel avoid any corrosion of  PV cells and/or the heat exchanger
