Smart panels for smart buildings

The solar panel for every type of building

With over 800 installations, the DualSun Spring panel is adapted for any type of building that has both hot water and electricity needs. Spring is an ideal solution for renovation and new buildings to respect new building codes and standards.

3x more energy per m2

More power, less rooftop space & zero risk of overheating

In addition to being a competitive and powerful solution to respond to building regulations, DualSun presents other key advantages:

Rooftop space

A DualSun installation takes 30% less space than two separate PV and thermal installations with the same power output.

picto-surchauffe-v1-150x150

Zero overheating

Spring’s low stagnation temperature (80°C) garanties zero risk of overheating in the summer months and simplified maintenance.

Simple installation

Panels were designed for standard and easy installation with the same dimensions as standard PV panels and Plug‘n Play DualQuickFit connectors.

Domestic hot water

Buildings represent 30% of the world’s energy consumption.
DualSun aims to make our buildings more energy independent by generating solar heat and electricity.

How domestic hot water works

DualSun Spring panels optimize every square meter on the roof by producing hot water and electricity to:

chaleur-thermique-panneau-solaire-hybride-dualsun-ntcobhzng2jm87khgglsdyilnqya0a08366pljzv9c

Preheat the domestic hot water system and store as much energy as possible in a solar hot water tank, which acts as “battery storage” for hot water consumption both in the mornings and evenings

Use the electricity directly in the building during the day, and send any surplus electricity to the grid

Municipal pool heating

With one unique hybrid solar installation, DualSun allows to heat the pools, provide hot showers, and generate solar electricity.

DualSun panels are particularly well-adapted for pool heating, because the panels have better thermal performance at low heating temperatures.

Moreover, the water from the pools circulates directly behind the photovoltaic cells to cool the cells and thus increase the PV efficiency : the DualBoost effect.

Peat and maintain the temperature of the pools using a plate heat exchanger, with a backup boiler during winter months (if needed) and preheat the hot water system for the showers using a second plate heat exchanger and a solar hot water tank

WHAT PIPING IS RECOMMENDED BETWEEN THE SOLAR PANELS AND THE HOT WATER TANK?

We recommend using multi-layer piping to the low stagnation temperature.

WHAT IS THE ENVIRONMENTAL COST OF SOLAR PANELS?

The environmental cost or “breakeven point” of solar panels is approximately 2-3 years.

WHAT MOUNTING SYSTEMS CAN BE USED TO INSTALL DUALSUN SPRING PANELS?

The DualSun Spring panel can be installed in either portrait or landscape mode.

Offers developed with our partners

The efficiency and reliability of the DualSun Spring panel were recognized and well-appreciated by HELIOPAC, French leader in hot water technologies for buildings, who chose to combine Spring panels with HELIOPAC heat pumps.
