OUR MISSION

Working together to reduce CO₂ emissions

The sun can’t do it all. But if we work together, it can do a lot. At Dualsun, we believe that solar technology and the power of community are incredible drivers for accelerating the energy transition. Since 2013, we’ve been manufacturing cutting-edge solar solutions, working at every level to help people understand, use, and bring our technology to life. We empower today’s consumers to become tomorrow’s energy producers.

Designed in France

Since 2010, we have developed our solar innovations at our R&D center in Marseille, France.

Industrial excellence

Not all our panels are produced in France (yet). We select the world’s best factories based on strict environmental and social criteria.

Low-Carbon Certified

Our panels are certified low-carbon. It’s the least we can do.

30-year warranty

Our panels are built to last: the PV performance is guaranteed 30 years. Our technical teams are available to support you for free, for life.

The 2-in-1 solar panel for all your energy needs

At Dualsun, we have designed an innovative hybrid PVT solar panel that converts solar energy into electricity and heat with the same panel. 

The SPRING PVT panel produces up to 6 times more energy than a standard photovoltaic panel.

The SPRING can be coupled with heat pumps or used directly to provide all of a building’s energy needs: electricity, hot water and heating. And in the case of private or public swimming pools, they can heat pools too. 

High performance.
Low-carbon.

Designed to generate maximum electricity with minimal environmental impact — from manufacturing to recycling.

performance guaranteed after 30 years.

A FLASH panel produces in 2 years the amount of energy needed to manufacture it.

Tailored solar installations for every application

Dualsun’s high-performance PVT and PV panels can meet the energy needs of all types of buildings and applications — from homes to apartment buildings, public swimming pools, sports stadiums, and beyond. Our expert technical team offers comprehensive support throughout every stage of your project.

PVT SYSTEMS

Custom PVT solutions for every 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 up to 6 times more solar energy from rooftop surfaces compared to PV.

PVT-Optimized Ground Source Heat Pump

A “match made in heaven”.

Dualsun’s SPRING4 hybrid solar panels are the perfect addition to a ground source liquid-to-water 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-Source Heat Pump

Major energy savings—without the need for an outdoor unit.

Dualsun’s SPRING4 finned hybrid panels pair perfectly with a liquid-to-water heat pump to generate electricity, hot water, and solar heating for your building.

  • Utilizes PVT panels as a thermal source, eliminating the need for boreholes in liquid-to-water heat pumps.
  • Silent alternative to air-to-water heat pumps and dry coolers.
  • Ideal for applications with significant summer thermal requirements.
  • Reduces reliance on district heating, gas, electricity, or biomass for heating and cooling.
  • Provides the option for future integration with geothermal storage.

Provides 6 times more solar energy from the roof surfaces compared to PV.

PVT Solar Pre-Heating

A simple, effective, and cost-saving solution from day one.

The SPRING4 hybrid PVT panels can be easily integrated with an existing domestic hot water tank or pool heating system, without the need for a heat pump.

By preheating the water, they help reduce energy consumption by up to 30%, using only the power of the sun.

Ideal for all types of buildings in warm regions or as a first step toward a high-performance solar installation!
