DualSun aims to reduce the energy consumption of buildings by offering efficient and competitive water heating solutions with hybrid solar panels. We believe in the potential of on-site energy production and consumption.

One of the ways in which our Spring hybrid panels can be used is to  generate the heat and electricity required by water-to-water heat pumps. The heat exchanger located on the rear side of the Spring hybrid panels heats up the water which is then transferred to the cold source of the heat pump. Meanwhile, the front side of the panel contributes to the energetic output by producing photovoltaic electricity. 

This system is optimally designed to cover heating needs and works very well at low temperatures, meaning that it resists well to chilly winter temperatures and in cold climates!

As far as thermal energy side is concerned, the DualSun Spring has an exchanger whose job it is to collect the available heat, which can either be sourced from direct sunlight or through a simple exchange with the outside air, and use it to heat the glycol water found in the primary circuit of the heat pump.

In terms of the photovoltaic side, DualSun Spring panels generate electricity which can either be used by the building in powering its heat pumps (or other devices) or fed back into the grid.

Heat pump coupling applications

Water-to-water heat pump coupling without geothermal probe

The DualSun Spring exchanger collects heat from the photovoltaic cells and heats a storage tank located on the heat pump’s primary circuit.

This coupling works equally well on sunny days, at night or during spells of bad weather.

Water-to-water heat pump coupling with geothermal probes

During the summer and in favorable weather conditions, the surplus energy captured by the roof-mounted hybrid solar panels that remains unused used by the building is stored in geothermal probes in order to regenerate the temperature of the soil. This surplus energy is then reused when the needs arises, such as in winter. 

The heat drawn from the ground in the wintertime is thus regenerated during the summer through the injection of surplus solar heat. As such, the soil is not depleted and maintains its balance from one season to the next.

How the heat pump and solar hybrid panel coupling works

This coupling is set in motion whenever there is a difference in temperature between the external air and the water inside the panels, meaning that it functions both on sunny days and during the night or in poor weather conditions. 

On sunny days, the sun heats the panels and the fluid circulating inside. When there is no sunshine, the solar panels’ heat exchanger collects energy through an exchange with the external air.

This characteristic allows the system to operate at very regular performance levels throughout the year and exceed the performance of a classic thermal solar system. 

The excellent heat exchange between the photovoltaic cells and the Spring solar panel’s heat exchanger allows the cells to operate at a lower temperature than classic photovoltaic panels, which makes them more efficient. This coupling provides a 10 to 15% improvement in energy production!

Therefore, the heat transfer performed by the system not only supplies the building with solar heating and hot water, but it also considerably cools down the panel cells and thus increases their overall efficiency. 

On average, our hybrid solar panels produce 4.5 times more energy than a classic photovoltaic panel.

DualSun Spring panels are suitable for any kinds of buildings that have both hot water and electricity needs. They present an ideal solution that can be incorporated during the renovation of old structures or the building of new structures in order to comply with the new energy efficiency standards.
