Thermovoltaic technology Cogen'Air®

With our patent Cogen’Air® panel, we have reviewed the traditonal photovoltaic panel. Not only it produces hot air and electricity, but it has a thermal efficiency much higher than its electrical efficiency.

This hybrid panel produces more heat than electricity!

What differences between a photovoltaic panel and the hybrid solar panel Cogen'Air®?

When a photovoltaic panel collects rays of sunshine, it only converts 20% into electricity.

Standard panel efficiency

Standard photovoltaic panel

Thermovoltaic panel with 250Wc + 9,8% of electricity, 744W of heat and an efficiency more than 60%

Hybrid solar panel Cogen'Air®

How does it work?

A clever mix of technology

Heat exchangers

Watertight enclosure or cap

On the front side, the panel produces electricity.

On the rear side, thanks to a heat exchanger developed by BASE, heat is transferred to an air flow below the panels. With the help of turbulators, it allows us to get hot air by lingering it on the back of the photovoltaic panels.

At the slightest ray of sunshine, Cogen’Air® rises up in temperature!

Fonctionnement panneau photovoltaïque thermique Cogen'Air

Thanks to Cogen’Air®’s innovative heat recovery system, the released heat is extracted for the purpose of heating and drying. The air flowing on the back of the panels avoids the cells’ overheating and improves its electrical efficiency.
