Our solar panels,
all your energy needs
Dualsun panels installed worldwide
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.
OUR SOLUTIONS
The best of solar at your doorstep
For those of you looking to maximize your self-consumption of electricity. For those who would also like a solar solution to heat your water—or even your home or building. For those who don’t have space on your rooftop or if you are renting. Dualsun has thought of you, and brought the best of solar technology to serve your needs.

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.
SPRING (PVT): ELECTRICITY & HEAT
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.
x 6
The SPRING PVT panel produces up to 6 times more energy than a standard photovoltaic panel.
4end-uses
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.
FLASH (PV): ELECTRICITY
High performance.
Low-carbon.
Designed to generate maximum electricity with minimal environmental impact — from manufacturing to recycling.
85%
performance guaranteed after 30 years.
2years
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!
