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:
PV efficiency drops when cells are hot. The thermal side of a PVT module removes heat from the PV cells, which can:
With PVT, you share:
Even though a PVT module is more expensive than standard PV or a flat plate collector alone, the total system cost per unit of useful energy is often lower.
PVT displaces both grid electricity and fossil-based heat:

Combining PVT panels with a heat pump creates one of the most efficient renewable energy systems available today.
Result: A significantly higher overall COP and superior seasonal performance
PVT + heat pump transforms your roof into a compact, high-efficiency renewable energy plant—producing both heating energy and clean electricity from one integrated system.
Soletks hybrid PVT panels are not conceptual prototypes.
They are laboratory-tested, field-proven, and validated under controlled thermal and electrical conditions.
Full-size monocrystalline PV modules (450–600 W class)
Laser-welded aluminum absorber with optimized heat-spread geometry
Selective coating with high absorptance and low emissivity
Micro-channel heat exchanger integrated beneath the PV cells
Rear-mounted thermal control layer for PV temperature stabilization
Stable thermal output of 350–500 kWh/m²·year (climate dependent)
Electrical yield at 90–95% of standalone PV modules
Panel temperature reduction of 10–18°C under full irradiance
Zero hotspots or delamination during continuous stagnation cycling
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.
Soletks eliminates common failure points:
Panels use aluminum + EPDM sealing with controlled drainage to prevent moisture accumulation and corrosion.
Soletks designs complete PVT systems, not loose components.
Real projects—hotels, apartments, clinics, worker camps—run hot water 365 days a year.
Panel lifespan is measured in years of real operation, not hours of laboratory sunshine.
Stable electrical performance
Predictable thermal output
No fragile glass tubes
No polymer creep
No stagnation failures

Soletks products are not built on promises —
they are built on physics, materials science, and tested thermal behavior.
| Option | Roof Use | Output Type | Energy per m² | CAPEX per energy unit | Complexity |
|---|---|---|---|---|---|
| PV only | Electricity | kWh electric only | Medium | Good for electricity | Simple |
| Solar thermal only | Heat | kWh thermal only | High | Very competitive for DHW | Medium |
| 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
| System | Annual Energy Yield (per m²) | Economic Result | Payback |
|---|---|---|---|
| PV only | 180–220 kWh electric | Good, but limited by roof | 5–8 yrs |
| PVT hybrid | 180–220 kWh electric + 350–500 kWh thermal | Thermal replaces expensive gas/electric heat | 2.8–4.5 yrs |
PV-only: ~18–22 kWp → 20–35 kWh/day → Payback ~6 yrs
PVT: same roof → electricity + 1,500–2,500 L/day DHW → Payback ~3–3.8 yrs
High sun + hotel demand = PVT extremely efficient
| System | Annual Energy Yield | Economic Result | Payback |
|---|---|---|---|
| PV only | 250–380 kWh / m² | Excellent electrical output | 3.5–6 yrs |
| PVT hybrid | 250–380 kWh + 550–750 kWh thermal | Peak ROI due to DHW & pools | 2.0–3.0 yrs |
PV-only: strong production but most goes to HVAC
PVT: electricity + daytime pool + showers
→ ROI often < 2.5 yrs
Medium prices, high sun, strong thermal demand
| System | Annual Energy Yield | Economic Result | Payback |
|---|---|---|---|
| PV only | 220–350 kWh/m² | Very strong results | 4–7 yrs |
| PVT hybrid | 220–350 kWh + 350–600 kWh thermal | Best ROI in laundry / food / resorts | 2.2–3.8 yrs |
Industrial laundries, textile washing, agro-food cleaning → massive hot water consumption.
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.
Decision Logic
Schools, manufacturing halls, logistics warehouses
ROI still strong, engineer-friendly
Maximum energy per m² when space is constrained
PVT preheats return loop + PV powers compressor
Seasonal COP skyrockets — ultimate efficiency combination
