Optimal savings, zero compromise on quality

A product range of photovoltaic panels focused on quality and performance.
  • High Performance The FLASH product range was developed by our solar experts to combine the best high-performance solar cell technologies for maximum efficiency.
  • Low-carbon The FLASH panel releases less CO2 than a standard solar PV panel. The product range was designed to produce maximum electricity with minimum impact on the environment.
  • A commitment to quality Manufacturing takes place in carefully selected sites that are strictly audited with specifications designed by our expert engineers in Marseille, France.

Photovoltaics: the essential technology for making our buildings energy independent

DualSun, industry expert in solar technologies, has developed a range of photovoltaic panels focused on quality and performance

To achieve this, DualSun works with specialized manufacturing partners to produce the best photovoltaic solar panels with the least environmental impact while meeting the rapidly growing market demand.

Reliability and performance

Our FLASH photovoltaic panels are manufactured to exacting standards with each production batch being systematically audited by a specialized third-party auditing firm.

The high-efficiency monocrystalline cells of the panel as well as the care and quality we bring to its design make the Flash panel one of the most competitive solutions on the market.

Low carbon footprint  and 95% recyclable 

With FLASH panels, like the SPRING panels, DualSun puts a strong emphasis on reducing as much as possible the environmental and carbon footprint of the panels. 

DualSun FLASH’s exceptional warranties

DualSun FLASH panels are designed and manufactured to last over time. That’s why we offer some of the strongest product warranties on the market:

  • 20-year product warranty offered at time of purchase 
  • +5 years of product warranty after free activation on your MyDualSun space from the date of installation
  • 25-year performance warranty on photovoltaic production. Parts and labor covered by DualSun if the product is defective and subject to product expertise

DualSun FLASH panel certifications

DualSun FLASH panels meet the highest international quality standards.

You can be sure that you have chosen high-performance solar modules without compromising on quality.

All DualSun FLASH panels are certified according to the following standards: 

  • IEC for the European market ;
  • CEC for the Australian market;
  • UL listing for the US market. 

FLASH & SPRING Shingle : Des panneaux solaires compatibles et visuellement 100% identiques

Our FLASH (photovoltaic) and SPRING (hybrid) solar panels have the same photovoltaic characteristics and are visually indistinguishable on the front side.

  • Same dimensions
  • Same aesthetics
  • Same electrical characteristics

These panels, with a perfectly identical exterior design, can be installed side by side in the same installation. Their identical design guarantees the aesthetic and technical continuity of your installation.


Frequent questions about the FLASH panel

  • 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.

    It would not be rational for DualSun today to invest in a plant that would laminate photovoltaic panels in competition with large manufacturers already present on this market (mostly Asian). Indeed, massive investments have been made there. This leads to a very strong pressure on the price of photovoltaic components on the one hand, but also a very high level of automation and therefore quality of these manufacturers.

  • What is the environmental cost of solar panels?
    The environmental cost or “breakeven point” of solar panels is approximately 2-3 years. This means that the amount of energy needed to manufacture the panel is regenerated after 2-3 years of solar production of the solar panel.  The impact is thus minimal compared to the lifespan of solar panels (25+ years).
    In order to evaluate the environmental impact of product, there are different environmental analysis methodologies such as Lifecycle Analysis (LCA), the Carbon Balance, and the Simplified Carbon Evaluation.
  • What is the difference between the hybrid Spring panel and the photovoltaic Flash panel?

    The Spring is a hybrid solar panel that produces both electricity (photovoltaic) and hot water (thermal).

    The Flash is a photovoltaic panel that only produces electricity.
