Combining Cool Roof & Bifacial :

More PV Production & Less Energy Consumption

What is the issue? 

The problems linked to summer comfort have become a recurrent subject due to rising temperatures. It involves an increase in indoor temperatures and therefore a discomfort for the occupant. The traditional means of cooling are energy intensive and very often incompatible with the future environmental regulations.  

The consequences of over-heated rooftops:

  • Increase in the electricity bill
  • Deterioration of the roofing material and HVAC equipment
  • Thermal discomfort for the occupants


What is our combined solution ?

SOPREMA reflective membranes (Cool Roof) are one way to tackle the summer discomfort issue by benefiting from the reflective and emissive capacity of their membranes (such as SOPRASTAR) which will keep the roof cooler than a traditional membrane. The Solar Reflectance (SRI)Index is tested and approved through the ASTM E 1980-0 norm.






SOPRASOLAR offers to benefit from all the advantages of SOPREMA’s Cool Roof membranes in addition to combining them with the bifacial technology. A bifacial module produces solar energy from both sides of the panel; therefore, you will be able to harness the rays of sunlight reflected by the white membrane.
