HKWELL MAX
Your solar energy independence, drawn from the air
What if the sun could heat your home even in the dead of winter? With HKWELL MAX, combine a heat pump and hybrid solar panels to meet 80% of your energy needs. Quiet operation, with no outdoor unit.
Aim for self-sufficiency
By combining electricity, hot water, and heating production, MAX enables you to exceed 80% energy self-sufficiency—without even adding a battery.
Increase the value of your home
Replacing an old boiler with MAX can improve your Energy Performance Certificate (DPE) rating by up to three steps. This improvement in energy class can boost your resale value by up to 10% (based on data from French notaries).
No outdoor unit
The solar-thermal heat pump draws its energy via the heat exchanger in the roof-mounted panels. No more noise, no outdoor unit, and no disputes with neighbors.
Our innovation
Generating heat from heat. And even from cold!
A panel that generates power even at night
A heat pump without an outdoor unit
The heat pump in the MAX system has been specially adapted to generate heat from cold air, even when the temperature drops below 0°C and down to -15°C.
Because it draws energy from the SPRING MAX panels, it does not even require an outdoor unit to operate.
SPRING MAX
The panel that gives wings to your production
The SPRING MAX panel combines all the innovations found in other Dualsun panels: cutting-edge photovoltaic cells, an ultra-robust heat exchanger, and a minimalist aesthetic.
It also adds a new innovation: thin fins on the back to maximize energy exchange with the air. And that makes all the difference.

6 bar
This is the heat exchanger’s pressure resistance, made possible by its 100% aluminum structure.
6.4 m²
This is the heat exchange surface area of a single panel, thanks to the fins.
240 The best environmental performance on the market
By tripling the energy yield per installed square meter and committing to reducing the carbon footprint of its production, we have created—with MAX—the most eco-friendly solar technology available.
30x
Your installation saves, on average, 30 times more CO₂ than was emitted during its construction.
10 g CO₂e / kWh
carbon footprint of a panel, 2 to 3 times lower than the average for panels on the market.
Invelia Heat Pump
Performance Made in France
The Invelia water-to-water heat pump—Arkteos’s latest-generation model—fully harnesses the thermal potential of hybrid panels.
Already equipped with the market’s best technologies (including an Inverter compressor), it has been specifically adapted for the Dualsun MAX installation.
Boost your energy performance rating
The MAX system delivers energy performance superior to any other solution on the market. It enables you to jump up several energy efficiency classes and instantly increases your property's value.
3 classes
When replacing a boiler, MAX allows you to jump up to 3 classes.
+10%
This is the average increase in resale value resulting from a two-class jump (based on data from French notaries).
