Solar Domestic Hot Water with SPRING hybrid solar panels

DualSun promotes energetic autonomy by helping buildings produce their own heat and electricity through solar energy. We believe in the potential of on-site energy production and consumption.

Our Spring panel offers a twofold advantage in this regard. The front panel generates photovoltaic electricity while the rear panel produces domestic hot water by means of a heat exchanger, thus providing with free hot water that has been sourced in an environmentally-friendly manner.

The heat produced by the rear side of the Spring panel heats up the water inside the hot water tank. The tank then stores the heat like a battery, using it to meet the building’s hot water needs throughout the entire duration of the day.
The electric output generated by the Spring panels is either consumed by the building itself or fed into the electric grid to be sold to the public network.

How a Solar Water Heater Works

In the Individual Solar Water Heater and Collective Solar Water Heater configurations, the water is directly heated by the DualSun Spring panels while circulating in a closed loop between the panels themselves and a solar hot water tank that is generally located inside the building that the panels are installed upon. An intelligent controller triggers water circulation as soon as it detects enough sunlight to provide heat to the hot water tank.

When used as part of a Sanitary Hot Water system, the DualSun Spring panel produces twice the quantity of energy per m² as a simple photovoltaic panel!

An installation of Spring panels supplements the main domestic water heating system. When used less frequently, the lifespan of the conventional water heater increases while its consumption levels and associated energy bills decrease.
