PVT Hybrid Solar Systems — One Panel, Two Energies

Simultaneous power and heat from the same surface.

When roof space is limited, PVT gives you the maximum energy per square meter.

What is a PVT System?

PVT (Photovoltaic-Thermal) is a hybrid solar panel that produces electricity and heat at the same time from a single module:

Front Side

Photovoltaic cells generate electricity

Rear Side

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.

Why PVT Instead of Separate PV + Thermal?

Maximum Energy per m² of Roof Area

For many projects, roof or façade area is the main limitation. PVT allows you to:

Produce kWh of electricity + kWh of heat on the same square meter
Reach much higher total solar yield compared with PV alone

Ideal for:

Apartment buildings
Hotels, hospitals, nursing homes
Offices & mixed-use buildings
Industrial/food plants with hot water demand

Better PV Efficiency Through Active Cooling

PV efficiency drops when cells are hot. The thermal side of a PVT module removes heat from the PV cells, which can:

Improve electrical efficiency compared with the same PV module without cooling
Increase annual PV output, especially in hot climates or on dark roofs

Lower System Cost vs Two Separate Systems

With PVT, you share:

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.

Thermal Circuit Designed Around PV Physics

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:

Cell fatigue
Micro-cracking
Long-term electrical yield decay

Electrical Yield Preserved, Not Sacrificed

A PVT panel that loses 20–30% PV output is unacceptable. Our architecture extracts heat below the PV operating zone, ensuring:

No shadowing
No hydraulic deformation
No clamp hotspots
No solder-joint fatigue

Field data confirms 90–95% of pure PV output, while also generating thermal gain.

Real Thermal Performance — Not Cosmetic Water-Cooling

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:

Technology:

High thermal conductivity plate (k > 200 W/m·K)
Optimized fluid volume
Controlled ΔT extraction strategy

This ensures:

Stable heat output in summer
Predictable return temperatures for heat pumps or storage
No boiling, stagnation, or thermal runaway

Structural Integrity for Long Service Life

PVT panels endure UV + thermal cycling, moisture ingress, corrosion, mechanical stress, and high stagnation temperatures.

Soletks eliminates common failure points:

No vacuum tubes
No plastic manifolds
No adhesive-based thermal paths
No uncontrolled stagnation risk

Panels use aluminum + EPDM sealing with controlled drainage to prevent moisture accumulation and corrosion.

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.

PVT vs PV ROI — Realistic Regional Examples

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.

Roof constraint: 80–120 m² usable area
Electric tariff: local commercial rate
DHW demand: 1–4 tons/day @ 45–55°C
PVT output: 1 unit delivers electricity + heat
PV output: electricity only

🔵

Europe (EU)

High electricity cost + heating demand = PVT perfect

👉 Assumptions

Electricity: €0.18–0.28/kWh (commercial)
Gas / heating cost: €0.07–0.12/kWh
Good solar irradiation: 950–1,350 kWh/m²·year
Hot water: constant demand (hotels / hospitals / residences)

System	Annual Energy Yield (per m²)	Economic Result	회수 기간
cURL Too many subrequests.	180–220 kWh electric	Good, but limited by roof	5–8년
PVT hybrid	180–220 kWh electric + 350–500 kWh thermal	Thermal replaces expensive gas/electric heat	2.8–4.5 yrs

Example (France 80–100 m² hotel):

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

PVT

~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.

PVT: The Most Cost-Effective Renewable Heat Source for Europe

PVT delivers the same principle — naturally and continuously.

Heating Configuration	Typical COP	Relative Heat Cost
Air-source heat pump	~3	Higher
Water-source heat pump	~5	더 낮음
Water-source + waste heat	~6	최저가
PVT-assisted heat pump	5–6+	최저가

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.
