2-in-1 technology: How does a hybrid photovoltaic thermal panel (PVT) work?

A standard photovoltaic panel converts 20% of incoming solar light into electricity and the rest of the energy (80%) is lost as heat. In addition to being wasted, this heat is also detrimental to the solar panel’s photovoltaic efficiency, which drops when the panel rises in temperature.

With its 2-in-1 solar technology, the Dualsun SPRING hybrid panel produces electricity on its front side, then recovers the extra energy to heat circulating water using an innovative heat exchanger on its back side.

The water flow in the exchanger has 2 benefits:

  • DualHeat: The water can reach a temperature of up to 70°C and can therefore be used to cover the building’s various heating needs.
  • DualBoost: The water also cools the photovoltaic cells and improves electricity output by 5 to 15% depending on usage.

A hybrid solar panel made in France

Dualsun’s SPRING technology is developed by our engineers at our research center in Marseille, Provence.

  • The heat exchanger is manufactured at the Dualsun plant in Ain (01) using components from Europe and the Dualsun FLASH panel (manufactured in Asia).
  • The Dualsun plant has ISO:9001 certification and the Industrie du Futur label.

The Dualsun SPRING panels have an “IMF” certificate attesting that they are manufactured in France: FR-IMF-2019-198.

A connected solar panel

Intelligence is integrated into the Dualsun SPRING panel

Dualsun engineers have developed a system to monitor both your electricity and your hot water production in real time on your computer or your smartphone. For the hot water, a temperature sensor is placed in the heat exchanger of the Dualsun SPRING panel and connected to a control unit. This monitoring system also notifies you in case of an anomaly or defection.

SPRING panel certifications

In 2013, the SPRING panel was the 1st hybrid solar panel in the world to obtain the new Solar Keymark “hybrid solar” thermal certification. 

Today, all SPRING panels are certified to European IEC (photovoltaic) and Solar Keymark (thermal) standards. 

Our panels also have CEC certification in Australia and UL listing (photovoltaic) and SRCC (thermal) certifications in the USA.

A sustainable solar panel

We continuously innovate to reduce the carbon emissions and environmental impact of Dualsun SPRING panels.

  • Ethical: Dualsun is strongly committed to making its hybrid solar panels environmentally friendly.
  • Recyclable: Dualsun carefully selects all manufacturing materials. As a result, the SPRING solar panel is nearly 95% recyclable!
  • Durable: the “energy payback” of the SPRING solar panel is 1 to 3 years for a lifespan that exceeds 30 years.

  • 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.
