Our team has been developing low carbon solutions since 2012

Synapsun advises manufacturers in the life cycle analysis of what they produce and what they consume

To meet the specifications of the Energy Regulatory Commission, we have been developing low-carbon solutions for the French market since 2012.We encourage manufacturers to take part in a process of analyzing the life cycle of what they produce and consume and support our partners throughout the optimization of their environmental impact. We assist them during their carbon footprint assessment process.

Since 2012, we have also helped developers to position themselves on the most powerful technologies but also the least impactful on the environment.

We support them in their applications for calls for tenders and ensure the supply of the winning modules.
