INVITAIC is a company specialized in building-integrated photovoltaics (BIPV), which recently launched an innovative bifacial PV system with cool roof coating, which can increase the energy output of the PV system, reduce the cooling energy consumption of the building, and provide customers with a high-efficiency and energy-saving BIPV solution.
The bifacial PV system uses high-strength double-sided glass, high conversion efficiency, high mechanical load, and supports customer customization, which can adapt to different building forms and styles. The design of the system is inspired by a Spanish study, which found that using cool roof coating under the roof bifacial PV system can increase the energy output of the PV system by 8.6% compared to the single-sided PV system, and the economic benefit per kilowatt peak is about 18.3 euros.

Cool roof coating is a coating with high reflectivity and high emissivity, which can reduce the temperature of the building roof, thereby reducing the cooling demand of the building and the urban heat island effect. The study was conducted on a building in Barcelona, Spain, where four sets of PV systems consisting of three bifacial PV modules connected in series were installed, namely single-sided PV system, bifacial PV system (normal ground), bifacial PV system (cool roof coating ground) and bifacial PV system (other types of PV modules). The experimental results showed that the bifacial PV system (cool roof coating ground) had the highest energy output, 8.6% higher than the single-sided PV system, and the economic benefit per kilowatt peak was about 18.3 euros. In addition, the cool roof coating can also reduce the ground temperature of the unshaded area (-3.8°C) in summer, further saving the cooling energy consumption of the building.
INVITAIC’s bifacial PV system, combined with cool roof coating, can bring customers double benefits: increasing energy output and reducing cooling energy consumption, both of which can bring economic benefits. The system not only can improve the aesthetics and functionality of the building, but also can reduce carbon emissions and promote sustainable development. INVITAIC is committed to providing customers with the best quality BIPV solutions, and you are welcome to contact us for more details.
