In the heart of Marseille, DualSun realized one if its first hybrid solar installations in 2013 on an apartment building of 73 apartments. The 22 DualSun panels are coupled with 2 HELIOPAC water-water heat pumps to provide domestic hot water for the building. This solar/heat pump combination (heliopacsystem+®) allows the solar circuit to function even at low temperature for an optimal efficiency with high solar coverage, even in the winter months!

The energy performance of the installation is closely monitored and we observe that in summer months, solar covers 79% of hot water needs of the building, and in the winter 68%!
The electricity produced by the panels is entirely self-consumed within the building. The efficiency of this installation cuts the non-renewable hot water energy consumption by 4! The results exceeded our expectations.
