Custom solutions for every type of project
The Dualsun SPRING4 solar hybrid PVT panel is designed to maximize energy output by generating both electricity and heat.
And when SPRING4 panels are combined with a water-water heat pump, this power combination provides 4-6 more solar energy from rooftop surfaces compared to PV. See the various applications below:
PVT & Geothermal Heat Pump for Commercial Heating
A “match made in heaven”: Dualsun’s SPRING4 hybrid solar panels are the perfect addition to a geothermal heat pump to maximize borehole performance and reduce energy consumption:
- Solar PV (cooling of cells): increases electricity production and extended lifespan
- Heat pump: increases efficiency and reduces electricity consumption by 50%
- Boreholes: raises their temperature year-round, boosts system efficiency and output while avoiding costly additional drilling or ground damage
Provides 6 times more solar energy from the roof surfaces compared to PV.
PVT & Heat Pump for Commercial Heating
One system, all your energy needs: Dualsun’s SPRING4 finned hybrid panels pair perfectly with a solar thermal water-to-water heat pump to generate electricity, hot water, and solar heating for your building.
During the day, the panels capture solar energy to produce electricity and hot water, supplying this energy to the heat pump and significantly boosting its efficiency.
At night, thanks to the finned design of the SPRING4 heat exchanger, the panels continue to capture heat from the surrounding air to power the heat pump.
An innovative solution that delivers major energy savings—without the need for an outdoor unit.
Provides 6 times more solar energy from the roof surfaces compared to PV.
PVT & Heat Pump for Commercial Water Heating
Start simple: The heliopacsystem+ combines SPRING4 hybrid panels with a Solerpac water-to-water heat pump to deliver up to 90% of your hot water from solar energy—driving major energy savings.
Ideal for buildings with high energy and hot water demands—like nursing homes, hotels, and restaurants—with hot water consumption starting at 2,000 L/day at 50 °C.
Provides 3 times more solar energy from the roof surfaces compared to PV.
PVT & Heat Pump for Community Pool Heating
The perfect wave: Dualsun’s SPRING4 PVT hybrid panels are an excellent fit for public pools, which have high energy and hot water demands for heating both pools and showers.
The heliopacsystem+ combines SPRING4 panels with a Solerpac heat pump to deliver optimized performance, with 80–90% of the energy coming from the sun—securing energy supply and significantly reducing operating costs.
Provides 4 times more solar energy from the roof surfaces compared to PV.
