Renewable heating with DualSun
Heating accounts for 70% of household energy consumption. It’s a major cost, but also a major contributor to greenhouse gas emissions, as heating is still too often fuelled by fossil fuels.
Our DualSun SPRING hybrid panels can supply your building with heat and electricity:
- heating your premises using solar energy by connecting them to a heat pump
- or by upgrading your heat pump with geothermal energy
These solutions are particularly effective in winter, especially in Nordic countries and Canada, because they operate at low temperatures. They enable you to drastically reduce your heating bill thanks to the right combination of renewable energies.
How does the DualSun solar heating solution work with a heat pump?
Your solar heating installation is composed of:
- DualSun SPRING hybrid panels and thermal accessories
- A water-to-water heat pump: this is exactly the same as a geothermal or hydrothermal heat pump, but the energy comes from the hybrid panels, not from the ground.
There is no need for an outdoor unit. This allows for less noise pollution than with an air-to-water heat pump, and no front-mounted equipment is required.
A water-to-water heat pump operates with two water circuits. The SPRING panels heat the water in the heat pump’s primary circuit.
- SPRING panels recover heat from the sun and ambient air, which is transferred to the water circuit at the back of the panel to power your heat pump.
- You can produce just as much on sunny days as at night or in bad weather! The panels recover heat from the air even at low temperatures: all it takes is a few degrees’ difference between the ambient air and the water circuit at the back of the panels.
On the photovoltaic side, DualSun SPRING panels produce electricity that can either be consumed in the building to power the heat pumps (or other appliances), or fed into the grid and sold on.
When SPRING DualSun panels are coupled with a heat pump, the very good heat exchange between the photovoltaic cells and the heat exchanger of the SPRING hybrid solar panel means that the cells operate at a lower temperature than simple photovoltaic panels, and therefore at a higher efficiency.
As a result, electricity production is improved by 10%, and with thermal production, the panel produces on average 4 times more energy than a conventional photovoltaic panel.
