Ⅰ. Core Product Features – Four Functions in One, Redefining Energy Utilization

The most distinctive feature of T/PV Pro is its deep integration of green power generation, residual heat utilization, intelligent charging, and multi-level energy storage.
This is not a simple combination of functions but a system designed for full synergy—self-sufficient, smart, and efficient.

1. Power + Heat: It recovers thermal energy while generating electricity, reducing energy loss and improving conversion efficiency.
2. Power + Storage: Surplus electricity can be stored in the system or used directly to charge electric vehicles and other devices.
3. Smart Control: An intelligent management system automatically allocates energy according to real-time demand, forming a closed loop of generation–consumption–storage without requiring additional equipment—truly an all-in-one energy solution.

Ⅱ. Versatile Application Scenarios – Empowering Multiple Sectors

Thanks to its modular, platform-based design, T/PV Pro can be widely applied across five major fields—residential, commercial, industrial, off-grid, and regional energy systems.

1. Residential & Community:
Villas / High-rise balconies: Provide household electricity, hot water, heating, and EV charging—all from solar energy—achieving energy independence and reducing utility costs.
New green communities: Serve as distributed clean heat sources to replace gas boilers and drive community-level decarbonization.
2. Commercial & Industrial:
Hotels / Hospitals / Schools: Meet the dual demand for continuous electricity and stable hot water, reducing massive energy costs and supporting sustainable operations.
Industrial parks: Supply preheated process water and daily electricity, cutting fuel consumption and achieving the “dual goals” of cost reduction and carbon reduction.
3. Special (Off-grid) Applications:
Oilfields / Remote areas: Operate as off-grid power and heating stations, providing reliable energy for critical infrastructure such as communication towers and monitoring systems.
RVs / Camping sites: Deliver mobile clean power and hot water for outdoor use, meeting the growing demand of the outdoor lifestyle economy.
4. Regional Energy Planning:
Enable seasonal energy storage: surplus heat from summer is stored underground and reused in winter for heating—maximizing regional energy recycling and efficiency.

Ⅲ. Key Product Technologies – Three Core Innovations that Define Industry Leadership

Backed by Soletks Group’s advanced coating, vacuum, and system integration technologies, T/PV Pro exceeds industry standards and builds a strong technological moat.

1. Thermoelectric Dual Supply: Combined instantaneous efficiency 88%, PV cell efficiency 23.3%, thermal efficiency ≥60%.
Efficient energy conversion technology enables simultaneous electricity generation and heat recovery, maximizing energy yield per unit area—solving the long-standing issues of “PV without heat” and “thermal without electricity.”
2. High-efficiency Insulation: 99.99% inert gas filling, polyurethane insulation (thermal conductivity 0.03643 W/mK), stable operation from -25°C to 80°C.
Vacuum insulation suppresses heat convection, inert gas minimizes conduction, and low-conductivity materials greatly reduce thermal loss—maintaining efficiency in extreme weather.
3. Reliable Structural Design: S-shaped fluid channel (0.6 MPa pressure resistance), one-time lamination.
The S-channel design enhances heat exchange and pressure resistance, while one-piece lamination prevents leakage—ensuring strong mechanical integrity and 25+ years of service life.

Ⅳ. Core Advantages – Efficient, Reliable, and Economical

Combining these advanced technologies, T/PV Pro offers three major advantages, balancing short-term cost savings with long-term value.

1. Economic Advantage: With an overall efficiency of 88%, energy yield per square meter far exceeds that of separate PV or solar thermal systems—delivering higher ROI and shorter payback periods for homes and businesses.
2. Reliability Advantage: Military-grade structural design and vacuum insulation ensure stable performance from -25°C to 80°C, with no leakage risk and a 25+ year lifespan—virtually maintenance-free.
3. Adaptability Advantage: Works both on-grid and off-grid, independent of power or gas networks. Suitable for urban households, commercial facilities, and remote areas—flexible and reliable in any scenario.

Ⅶ. Frequently Asked Questions (FAQ)

1. What is a PVT system, and how is it different from traditional solar panels or water heaters?
PVT (Photovoltaic-Thermal) systems use thermoelectric coupling to simultaneously generate electricity and recover heat from a single solar module—one sunshine, two uses. Compared with ordinary systems, it provides higher overall energy efficiency and greater value.
2. What are the requirements for installing a PVT system at home?
If your roof faces south, is unobstructed, structurally strong, and you have both electricity and hot water demand, then your home is suitable for installing a PVT system.
3. Does the PVT system require regular maintenance?
Maintenance is minimal—just clean the surface 2–3 times a year. There are no fragile internal components, so no disassembly or complex repair is needed.
