LisätietojaSimultaneous power and heat from the same surface.
When roof space is limited, PVT gives you the maximum energy per square meter.
PVT (Photovoltaic-Thermal) is a hybrid solar panel that produces electricity and heat at the same time from a single module:
Photovoltaic cells generate electricity
Heat exchanger recovers thermal energy for hot water, heating, pools or processes
Instead of installing one array for PV and another for solar thermal, PVT merges both into one integrated system.
Same roof. Same mounting. Double output.
For many projects, roof or façade area is the main limitation. PVT allows you to:

Instead of degrading under heat stress, PV cells operate in a cooler, more efficient condition, producing higher electrical yield while generating usable thermal energy.
All measurements were captured using calibrated sensors under controlled load—never spreadsheet simulations.
We publish sustained performance, not inflated peak numbers.
The solar industry is full of "PVT concepts" that perform well on paper but fail under real operating conditions. Soletks takes an engineering-led, not marketing-led, approach.
Uniform heat extraction is essential for reliable PVT operation. Soletks uses full-coverage aluminum absorber plates with micro-channel heat exchangers to prevent localized overheating.
Unlike spot-flow or partial-contact designs, our geometry eliminates thermal gradients—the root cause of:
A PVT panel that loses 20–30% PV output is unacceptable. Our architecture extracts heat below the PV operating zone, ensuring:
Field data confirms 90–95% of pure PV output, while also generating thermal gain.
Many "PVT" designs rely on laminated capillaries or shallow snake tubes that only cool panels under mild conditions and then stagnate or boil.
Soletks uses:
PVT panels endure UV + thermal cycling, moisture ingress, corrosion, mechanical stress, and high stagnation temperatures.

| cURL Too many subrequests. | Roof Use | Output Type | Energy per m² | CAPEX per energy unit | Complexity |
|---|---|---|---|---|---|
| PV only | Sähkö | kWh electric only | Keskitaso | Good for electricity | Simple |
| Solar thermal only | Heat | kWh thermal only | Korkea | Very competitive for DHW | Keskitaso |
| PVT hybrid | Combined | kWh electric + kWh thermal | Very high total | Often lowest per kWh (combined) | Higher but integrated |
PVT is not replacing classic PV or solar thermal in every case.
But when roof area is limited and there is simultaneous demand for power and heat, PVT is often the most efficient and compact choice.
Below is a practical B2B comparison, based on typical commercial buildings (hotel / student housing / clinic), where electricity + hot water demand coexist. It is not theoretical marketing—it reflects real energy prices, hot water loads, and panel performance.
High electricity cost + heating demand = PVT perfect

PV alone solves only half the problem.
PVT reduces the two largest cost centers at once: power + heat.
~200–300 kWh/m²
(electric)
~300–900 kWh/m²
(thermal)
~500–900 kWh combined
(electric + thermal)
PVT = PV output + 1–2× extra heat yield.
And unlike PV spillover: Thermal energy is always absorbed by DHW (hospitals/hotels/industry). Buffer tanks store excess heat → no curtailment.
This is why ROI accelerates.
| Heating Configuration | Typical COP | Relative Heat Cost |
|---|---|---|
| Air-source heat pump | ~3 | Higher |
| Water-source heat pump | ~5 | Alhaisempi |
| Water-source + waste heat | ~6 | Alin |
| PVT-assisted heat pump | 5–6+ | Alin |
Why PVT wins: PVT panels provide pre-heated water to the heat pump, dramatically improving COP while simultaneously generating electricity. This dual benefit makes PVT-assisted systems the most economically efficient renewable heating solution in Europe's climate.
