SPRING (PVT)
Double your solar potential with hybrid solar
The Dualsun SPRING hybrid solar PVT panel generates both electricity (PV) on the front side and heat (Thermal) on the back side.
It produces 6-8 times more energy than a standard PV panel, maximizing energy output while minimizing your carbon footprint.
SPRING works with every type of system: water heaters, heat pumps, pool heating, ground-source systems and more.
All to heat your home or building — without heating up the planet.
- 30-year warranty The photovoltaic output of all our panels is guaranteed for 30 years. And our customer support? Free. For life.
- Low-Carbon Certified Our entire range is fully low-carbon certified. Real environmental commitment starts here.
- Strict quality control Every panel is inspected one by one for peak performance and perfect finish.
Our innovation
The world’s first hybrid solar PVT technology
The front side
Converts sunlight into electricity.
The front side of the panel is composed of a high-performance photovoltaic panel for electricity generation (PV power of 425Wp).
The panel features cutting-edge TOPCon technology, delivering the highest cell efficiency for superior performance.
The back side
Captures heat from the sun, your roof, and the surrounding air.
The back side of the panel is composed of an innovative heat exchanger for thermal production (max thermal power of 940 W).
The panel is built with an ultra-durable, solar-grade aluminum heat exchanger—designed to last and ultimately, to be fully recycled.
The finned version offers 6.4 m² of heat exchange surface, allowing the panels to capture maximum heat—even at low temperatures—for reliable, year-round performance.
PVT SYSTEMS
Custom PVT solutions for every project
The Dualsun SPRING solar hybrid PVT panel is designed to maximize energy output by generating both electricity and heat.
And when SPRING panels are combined with a brine-water heat pump, this power combination provides 6x more solar energy from rooftop surfaces compared to PV. In some cases, it’s even up to 15x more energy.
PVT-Optimized Ground Source Heat Pump
PVT-OPTIMIZED GSHP
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
PVT-SOURCE HEAT PUMP
Major energy savings—without the need for an outdoor unit.
Dualsun’s SPRING4 finned hybrid panels pair perfectly with a brine-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
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!

Contact our engineering teamOur commitment
Engineered for excellence
We select high-quality components and manufacturing processes that minimize CO2 emissions, making cutting-edge solar technology accessible to a wider audience while ensuring top energy and environmental performance. We are proud to handle the final stages of SPRING production in France at our factory in Jujurieux.
European and French production
70% of the value of the SPRING panel comes from European production: the Dualsun SPRING panel is, therefore, Made in France.
The best ecological efficiency on the market
By optimizing the energy output of every square centimeter installed and committing to reduce the carbon impact of its production, we have created the most ecological solar technology with SPRING.
30x
On average, your installation saves 30 times more CO2 than it emits during its manufacturing.
10geqCO2 / kWh
The carbon footprint of one panel, which is 2 to 3 times lower than the industry average.

FAQ
Frequent questions about the SPRING panel
-
Where are the hybrid Dualsun SPRING panels manufactured?
In France! Our Dualsun SPRING hybrid solar panel (PVT) carries the Made in France label because it is proudly engineered and manufactured in France:
- Our team of engineers is based in Marseille in the South of France.
- Our factory is based in Jujurieux in the department of Ain. It is ISO 9001 certified to guarantee the outstanding quality of our products.
The proximity of our branches allows us to ensure better control of our production line and limit transportation costs.
Developing a high quality and eco-friendly product is our priority.
-
What is the origin of photovoltaic laminates of Dualsun SPRING and FLASH panels?
The photovoltaic cells of the Dualsun panels are manufactured and assembled in Asia.
They are said to be “laminated”, i.e. hot pressed against the glass plate used in the front of the panels.The photovoltaic industry is evolving very quickly with the development of gigantic factories capable of producing several gigawatts (1 GW = 109 W) of solar photovoltaic panels per year.
-
Can DualSun panels be recycled?
Yes! Thanks to SOREN (former PV CYCLE), Dualsun panels are 94,7% recyclable.
Dualsun panels have a lifespan of 25-30 years. What happens to the panels once they have reached the end of their lifetime, or how do we manage broken or defective panels? Dualsun panels are recycled via SOREN, the first worldwide take-back and recycling scheme for photovoltaic module waste. The cost of recycling is included in the initial price of the panel as an “eco-participation” cost.
Solar power deployment took off 10 years ago, thus major recycling needs will be necessary in 10-15 years from now. However, the industry is already prepared – both technically and financially.
