PVT-E Solar PV-Thermal Collector

The PVT-E Solar PV-Thermal Collector combines photovoltaic power generation with solar heat collection to extract more usable energy from the same solar module. Instead of allowing the heat generated by PV operation to go to waste, the system captures and transfers it for practical thermal applications.

This integrated design makes PVT-E a suitable choice for buildings and solar projects that need both electricity and heat, helping improve overall solar energy utilization while reducing the need for separate PV and thermal collectors.

Generate Power and Recover Heat

The key advantage of PVT-E is its dual-energy output. The photovoltaic section generates electricity, while the thermal section collects heat from the module.

This allows one collector to contribute to multiple energy needs:

Solar Radiation → Electricity + Thermal Energy → Building Energy Use

With a comprehensive solar utilization rate of up to 60%, the collector can deliver thermal energy output of approximately 2 times its electrical output. This makes better use of the available installation area, particularly for projects with high hot water or heating demand.

Better Thermal Performance

The PVT-E module features vacuum bonding technology, which improves the connection between the PV and thermal components and reduces thermal resistance.

Heat is transferred through a high-purity aluminum plate and optimized internal channels, helping distribute thermal energy evenly throughout the module. Temperature uniformity can reach approximately ±1°C, supporting consistent heat collection and stable operation.

The improved heat transfer design also helps enhance thermal energy utilization by more than 40%.

Protecting PV Performance

Heat management is an important part of hybrid PV-thermal systems. PVT-E incorporates an intelligent temperature control system that monitors module conditions and helps prevent excessive local temperature increases and PV hot spots.

High-precision sensors provide temperature information for system control, helping maintain a suitable operating temperature and supporting stable electrical and thermal output.

High-Efficiency Solar Cells

For electricity generation, PVT-E incorporates N-type TOPCon monocrystalline solar cells with multi-busbar technology.

The combination provides efficient photovoltaic conversion, a low temperature coefficient and reliable power generation under varying climate conditions. The photovoltaic and thermal functions work together within the same collector rather than requiring two separate solar installations.

Built for Outdoor Solar Installations

PVT-E is designed for long-term outdoor use with an anodized 6063-T5 aluminum alloy frame and weather-resistant sealant. The frame offers tensile strength of up to 180 MPa, while IP65 waterproof protection helps protect the module against outdoor exposure.

The durable construction provides resistance to rain, sand and other environmental conditions, making the collector suitable for a wide range of solar energy installations.
