ASCA, together with partners Eiffage Energie Systèmes, Les Maraichers Nantais and Groupe Olivier, is conducting an experiment using photovoltaic films in a greenhouse that will offset the energy costs of growing vegetables.

Installing photovoltaic technology in agricultural greenhouses is not a new idea. The experiment took place several years ago on solar panels of the 1st and 2nd generations. But the results were unsatisfactory: yields were later and smaller.

However, unlike the classic solar panel, photovoltaic films transmit 30% of the light, leaving the photosynthesis reaction possible.

Another advantage of the technology is the low weight of photovoltaic films. In contrast to the photovoltaic panel, which remains stationary after installation, the ASCA film can be easily incorporated into the mobile system, adapting to the time of year or weather conditions.

69 ASCA film photovoltaic modules occupy an area of ​​43 m² and are arranged in three different ways, horizontally inside the greenhouse, vertically inside and outside the building.

If the trials prove successful, they will be repeated on a large scale.
