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:
- Boreholes: Reduces borehole storage costs (number, depth), optimizes space for borehole storage, avoids additional drilling
- Solar PV (cooling of cells): increases electricity production and extended lifespan
- Heat pump: increases efficiency and reduces electricity consumption by up to 50%
Provides 6 times more solar energy from the roof surfaces compared to PV.
Major energy savings—without the need for an outdoor unit.
HKWell 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 mild climates or applications with high summer heating demands.
- 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.
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.
By preheating the water, the SPRING panels reduce energy consumption 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!

2-IN-1 INNOVATION
HKWELL SPRING4
HKWELL developed the world’s first hybrid solar PVT panel, a 2-in-1 innovation that combines performance and durability.
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.
