Advanced dual-function solar modules combining photovoltaic and thermal technologies.

High-efficiency photovoltaic cells on the front side
          Thermal absorber and fluid channels on the rear
          Multiple insulation layers to minimize heat losses and ensure long-term durability

2
          Hydraulic Circuit & Heat Exchanger

Complete thermal management system for optimal heat transfer and distribution.

Pumping station with flow and temperature control
          Heat exchanger for transferring energy to DHW tank, buffer tank, pool, or heating loop
          Complete safety group with valves, sensors, and expansion vessel

3
          Hot Water & Buffer Tanks

Thermal energy storage solutions for continuous hot water availability.

Domestic hot water (DHW) storage tanks
          Buffer tanks for heating or industrial process circuits
          Easy integration with heat pumps, boilers, or hybrid energy systems

4
          Electrical Side

Professional PV system components for maximum electrical efficiency.

PV string configuration with high-quality DC cabling
          String or centralized inverters for maximum conversion efficiency
          Smart monitoring and metering for both electricity and heat production

5
          Control & Monitoring

        PVT + Heat Pump = High-Performance Hybrid Plant
        
          Combining PVT panels with a heat pump creates one of the most efficient renewable energy systems available today.

How the Hybrid Works

The PVT panel provides low-temperature heat to the heat pump's evaporator or buffer tank

The PV side supplies part of the electricity required by the compressor

Result: A significantly higher overall COP and superior seasonal performance

Typical Use Cases

Low-temperature underfloor heating

DHW + space heating for residential and commercial buildings

Pool heating and dehumidification

Process water pre-heating for industrial applications

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.

Laboratory Tested & Field Proven

Soletks Hybrid PVT Panels — Engineered, Tested, and Validated for Real Performance

Soletks hybrid PVT panels are not conceptual prototypes.

They are laboratory-tested, field-proven, and validated under controlled thermal and electrical conditions.

Our Latest PVT Generation Features:

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

In Performance Testing, Soletks PVT Panels Demonstrated:

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

The Key Outcome:
        
          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.

6
        Why Soletks PVT — Engineering Built for Real Projects
        
          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.

1
            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

2
            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.

3
            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

4
            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.

5
            System-Level Integration — Not Just Selling Panels

Soletks designs complete PVT systems, not loose components.

Our engineering covers:
            
              Buffer + consumption tank configuration
              Constant-temperature return control
              Smart ΔT pump control
              Energy-priority logic (PVT → heat pump → boiler)

This prevents:
            
              Temperature overshoot
              Cavitation at high loads
              Seasonal thermal shock
              Bypass stagnation

6
            Tested for Commercial Duty Cycles

Real projects—hotels, apartments, clinics, worker camps—run hot water 365 days a year.

Soletks PVT panels are validated under:
            
              Continuous recirculation
              Sudden consumption peaks
              Daily start/stop thermal cycles
              Ambient temperatures above 40–50°C

Panel lifespan is measured in years of real operation, not hours of laboratory sunshine.

      PVT vs Conventional Solutions

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.

          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
