Mr. and Mrs. Jaskowiec are not like other clients. Indeed, Mr. Jaskowiec is a DualSun certified installer and the manager of the installation company Marion located in Montaigu in the Vendée.

If Mr. Jaskowiec is interested in DualSun, it is in more than one way.

Already, as part of his former activity, he was already building low-energy single-family homes. Then, he invested in and supervised the installation of several photovoltaic installations. Finally, he took over an activity whose core business is heating, plumbing, renovation and renewable energy. In these conditions, it is impossible not to meet us!

“We’re very happy, the temperature in the pool is very pleasant to swim in. The installation went very well, the DualSun team is very serious, then the installation took very little time.” Ms. Jaskowiec

Finally, Mr. Jaskowiec got to know DualSun at trade shows. Immediately interested in our innovative and Made In France offer, he wanted to install DualSun panels to be able to test them at home. The idea then was to be able to offer them to his customers. So the SPRING hybrid panel holds no secrets for them, neither from the user’s side nor the installer’s side!

By the time we met them, it had been 1 year ½ since the panels had been installed. They now recommend DualSun to their friends and family and can perfectly talk about the product in a customer meeting! “In terms of price reduction, we are starting to see the bill go down, we have real savings”. Ms Jaskowiec
