Base Innovation has developed an agricultural dryer powered by PVT photo voltaic panels.

Cogen’Air panels are PV modules with a warmth restoration system built-in into them. The module makes use of a warmth exchanger that recovers the warmth launched behind the panels for thermal use corresponding to heating or drying. This warmth extraction additionally will increase electrical effectivity by avoiding overheating of the PV system. Based on the corporate, the acquire when it comes to peak energy can attain as much as 10%.

The corporate has developed an clever regulation system that operates the velocity of the followers based mostly on the humidity degree of the heated air. This improves drying whereas limiting set up consumption. The answer additionally makes it potential to observe the operation of the dryer remotely and optimize its manufacturing.

Supported by the French power company Ademe, the system has been patented since 2013 and has mobilized greater than €500,000 ($551,000) in R&D over the previous 10 years.

Base Innovation at the moment gives its answer to design or modify agricultural dryers for bulk drying, bale drying, flat drying or bin drying. In apply, the panels mix a air flow infrastructure with a administration system that optimizes the operation of the dryer.

“We’re making assessments in different sectors of exercise,” mentioned firm consultant Benoît Michenot pv journal. “Our answer is attention-grabbing for decreasing the mass of water and thus decreasing the price of remedy per ton, however the seasonal constraints inherent in photo voltaic power and the expertise of low temperature drying have restricted alternatives on this business, till now.”

Michenot mentioned photo voltaic dryers provide low-temperature drying that impacts the worth of the ultimate product.

“Grass can have the identical dietary worth as cereal that’s fed to animals, so long as it’s dried in the precise circumstances,” he mentioned. “It additionally supplies area for the event of micro-food chains.”

The corporate already has 60 photo voltaic dryers working in France.
