PVT-E vs TPV-Pro: How to Choose the Right Soletks Hybrid Solar Panel for Your Project
PVT-E vs TPV-Pro: How to Choose the Right Soletks Hybrid Solar Panel for Your Project
Introduction: Why Choosing the Right PVT Technology Matters
As energy prices continue to rise and carbon reduction targets become stricter worldwide, hybrid solar technologies are increasingly being adopted in residential, commercial, and industrial projects. Among these technologies, PVT (Photovoltaic Thermal) hybrid solar panels stand out as a highly efficient solution, capable of generating electricity while simultaneously producing useful thermal energy from the same roof area.
However, not all PVT panels are designed for the same purpose.
In real projects, energy demand structures vary significantly:
Some projects prioritize electricity generation due to high grid prices or self-consumption strategies.
Others focus mainly on hot water or space heating, such as hotels, hospitals, district heating systems, or industrial processes.
Many projects require a balanced combination, but still have a dominant energy demand.
Choosing the wrong PVT configuration can lead to:
⚠ Underutilized thermal output
⚠ Lower-than-expected electrical yield
⚠ Suboptimal system economics
To address these different project needs, Soletks Solar has developed two distinct hybrid solutions:
✓ PVT-E – optimized for electricity-priority projects
✓ TPV-Pro – engineered for enhanced thermal performance
This article provides a clear, engineering-oriented comparison between PVT-E and TPV-Pro, helping you select the most suitable hybrid solar panel for your specific application.
Understanding Soletks PVT Solutions: One Concept, Two Design Philosophies
Before diving into individual models, it is important to clarify one key point:
PVT-E and TPV-Pro are not competing products — they are complementary solutions designed for different energy priorities.
Both belong to the Soletks hybrid solar family and share core advantages:
✓ Dual energy output (electricity + heat)
✓ Improved photovoltaic efficiency through active thermal extraction
✓ Higher total energy yield per square meter compared to standalone PV or solar thermal systems
✓ Reduced balance-of-system complexity
The difference lies in how the panel is optimized.
PVT-E Explained: Electricity-Priority Hybrid Solar Panel
Product Positioning
PVT-E is designed for projects where electricity generation is the primary objective, while thermal energy recovery is used to enhance overall system efficiency and provide supplementary heat.
Typical scenarios include:
Commercial rooftops with high daytime electricity consumption
Industrial buildings with strong electrical loads
Grid-connected or self-consumption PV projects
Regions with high electricity tariffs
Core Design Characteristics
The PVT-E panel focuses on maximizing photovoltaic output while maintaining stable thermal recovery:
High-efficiency PV cells
Carefully selected photovoltaic cells ensure strong electrical performance under real operating conditions.
Thermal backplate heat recovery
Heat generated by the PV cells is extracted through a well-designed thermal exchanger, reducing cell temperature and improving electrical efficiency.
Moderate operating temperature range
Optimized for low to medium temperature applications, ideal for domestic hot water preheating or low-temperature processes.
Electrical performance stability
By limiting excessive thermal stress, PVT-E maintains consistent electrical output over time.
Typical Applications for PVT-E
PVT-E is especially suitable for:
Office buildings and commercial complexes
Manufacturing plants with high electricity demand
Warehouses and logistics centers
Schools and public buildings with grid-connected systems
Projects prioritizing fast ROI through electricity savings
In these scenarios, the thermal output is a value-adding bonus, not the primary energy driver.
TPV-Pro Explained: Thermal-Enhanced Hybrid Solar Panel
Product Positioning
TPV-Pro is developed for projects where thermal energy demand dominates, such as hot water production, space heating, or industrial heat applications.
Rather than limiting thermal output to protect PV efficiency, TPV-Pro adopts a reinforced thermal design to deliver higher useful heat energy, even at elevated operating temperatures.
Core Design Characteristics
TPV-Pro is engineered with a clear thermal-first philosophy:
Enhanced heat transfer structure
Optimized absorber design ensures rapid heat extraction and higher thermal output.
Higher operating temperature capability
Suitable for applications requiring higher water temperatures, such as space heating or centralized hot water systems.
Robust thermal stability
Designed to operate reliably under continuous thermal load, day after day.
Balanced electrical generation
While electrical output is not the primary target, TPV-Pro still delivers stable PV performance within realistic operating ranges.
Typical Applications for TPV-Pro
TPV-Pro is ideal for:
Hotels, resorts, and guesthouses
Hospitals and healthcare facilities
Residential district heating systems
Swimming pools and wellness centers
Industrial hot water and low-temperature process heat
Agricultural and food processing facilities
In these projects, thermal energy represents direct fuel savings, often replacing gas, oil, or electric boilers.

How to Decide: A Practical Selection Logic
Rather than choosing based on model names alone, engineers and project developers should follow a demand-driven selection approach.
Step 1: Analyze Your Energy Demand Structure
Is your project mainly consuming electricity during daytime?
Or is hot water / heating the dominant load?
Step 2: Evaluate Roof Area Constraints
Limited roof space increases the value of dual-output solutions.
Higher thermal demand favors thermal-enhanced designs.
Step 3: Review Local Energy Economics
High electricity prices → prioritize electrical yield
High fuel or gas costs → prioritize thermal output
Step 4: Select the Appropriate Model
Choose PVT-E if electricity savings are your primary economic driver.
Choose TPV-Pro if heat generation replaces significant fuel consumption.
This logic ensures that the PVT system aligns with real operational value rather than theoretical efficiency alone.
Why Not Use Traditional Solar Solutions Instead?
It is reasonable to ask: why not simply combine traditional systems?
Limitations of Standalone PV Systems
⚠ Generate electricity only
⚠ Excess heat increases PV cell temperature, reducing efficiency
⚠ No contribution to thermal demand
→ Compare with flat plate solar collectors
Limitations of Traditional Solar Thermal Collectors
⚠ Produce heat only
⚠ No electricity generation
⚠ Often require separate roof space
→ Compare with heat pipe solar collectors
System Complexity and Roof Utilization
When electricity and heat are supplied by separate systems:
⚠ Roof space is divided inefficiently
⚠ Balance-of-system costs increase
⚠ Installation and maintenance complexity rises
In contrast, PVT systems integrate both outputs into a single module, simplifying system architecture and maximizing roof utilization.
Certification, Manufacturing Quality, and Reliability
Soletks hybrid solar panels are manufactured under internationally recognized management systems, including:
ISO 9001 (Quality Management) ISO 14001 (Environmental Management) ISO 45001 (Occupational Health and Safety)
All products are designed to comply with relevant CE standards, ensuring safety, reliability, and long-term performance in global markets.
Summary: Choosing the Right Hybrid Solar Panel
The choice between PVT-E and TPV-Pro should never be based on marketing claims alone.
Instead, it should be driven by:
✓ Energy demand structure
✓ Economic priorities
✓ Operating temperature requirements
✓ Project application type
In short:
PVT-E is the optimal solution for electricity-focused projects that benefit from thermal recovery.
TPV-Pro is the ideal choice for heat-intensive applications requiring strong thermal output.
Both solutions reflect Soletks Solar's commitment to engineering-driven hybrid energy design.
