Product Description
This PVT (Photovoltaic-Thermal) integrated photovoltaic module is a new generation of solar energy utilization equipment developed by Longpu Group, achieving simultaneous power generation and heat output from a single panel. The module features high-efficiency monocrystalline silicon photovoltaic cells on the front and a high-thermal-conductivity dedicated heat-absorbing core structure on the back, perfectly combining photovoltaic power generation and solar thermal collection technologies. While stably producing clean electricity, it efficiently recovers waste heat from module operation to produce hot water. Compatible with various thermal energy needs, it features standardized universal module dimensions and can directly replace traditional photovoltaic panels, making it a highly efficient integrated product in the fields of building-integrated photovoltaics and multi-energy utilization.
Product Feature
Core Advantages Introduction
1. Simultaneous production of dual energy sources on a single plate maximizes overall energy efficiency.
PVT modules achieve true integrated photovoltaic and solar thermal output. The high-efficiency monocrystalline silicon cell layer on the front side boasts an ultra-high photoelectric conversion efficiency of ≥21%, stably producing clean energy. The tightly bonded high-efficiency heat absorption structure on the back side can fully recover the waste heat generated by photovoltaic power generation, with a comprehensive thermal efficiency of ≥50%. A single panel simultaneously serves both power generation and heating purposes, significantly improving the overall utilization rate of solar energy, far exceeding the energy benefits of traditional single photovoltaic or single solar thermal products.
2. High thermal conductivity and low resistance structure, wide water temperature adaptability, and stable heating capacity.
The PVT internally incorporates two high-thermal-conductivity core solutions: all-aluminum/copper coils and microchannel flat tubes, which are tightly fitted to the battery backplate, resulting in minimal thermal resistance for heat transfer and outstanding waste heat recovery efficiency. The internal circulating medium flow rate can be flexibly adjusted, and the outlet water temperature stably covers 35℃～60℃ (which can be further increased in high-temperature summer environments), perfectly adapting to diverse heat energy needs such as domestic hot water preheating, heating return water temperature rise, swimming pool temperature control, and aquaculture water insulation. Simultaneously, it supports free networking of multiple modules in series and parallel to build large-scale PVT energy arrays, expanding into high-power integrated energy supply systems to meet high-flow heating and power supply demands.
3. Industrial-grade reliable packaging, ultra-weather resistant, and long-term stable outdoor operation.
The PVT boasts a robust overall structure and strong protective performance. The front panel utilizes low-iron ultra-clear tempered glass with a light transmittance of ≥91.5%, offering impact resistance, hail resistance, and resistance to strong outdoor wind pressure. The chassis features a sturdy anodized aluminum alloy frame, while the back panel is constructed from a high-thermal-conductivity metal composite material, achieving an overall protection rating of IP65 or higher . The product has successfully passed a full set of rigorous reliability tests, including thermal cycling, damp heat, and high/low temperature freeze-thaw cycles, ensuring stable operation in complex outdoor conditions across the entire temperature range of -20℃ to 85℃. It can provide long-term stable service in extremely cold, high-temperature, and rainy/humid environments.
4. Universal standard size, flexible and convenient installation, and extremely strong system adaptability.
The module's dimensions are completely identical to those of conventional photovoltaic modules on the market (approximately 2 square meters per module), allowing it to directly replace traditional rooftop photovoltaic panels without the need for additional dedicated brackets, perfectly compatible with existing photovoltaic roof layouts. The module body has pre-installed G3/4 internal thread and quick-connect standard water interface, enabling rapid connection to various water circulation pipelines and thermal storage systems. Additionally, it can be equipped with a DC water pump and intelligent temperature control cabinet as needed, achieving automatic circulation based on temperature difference sensing, intelligent start-stop operation, fully automated unattended operation and maintenance, and adapting to the retrofitting and upgrading of various new and old solar energy systems.
Application Scope
With its comprehensive advantages of dual energy output, high energy efficiency, high weather resistance, and flexible installation, this PVT photovoltaic thermal module can be applied in a wide range of clean energy supply scenarios:
1. Building-integrated photovoltaics (BIPV ): Rooftop photovoltaic retrofitting of villas, residential buildings, and commercial buildings, replacing traditional single photovoltaic panels, realizing integrated energy supply of building power and domestic hot water, perfectly matching the BIPV design.

3. Industrial and agricultural constant temperature heating scenarios : heat energy supply in multiple fields such as constant temperature of agricultural and aquaculture water bodies, constant temperature heating of swimming pools, preheating of process hot water in factories, and preheating of return water for underfloor heating.
4. Large-scale integrated energy projects : PVT large-scale array power stations composed of multiple components connected in series and parallel , distributed integrated energy power stations, integrated energy supply projects in new energy parks, and supporting large-scale integrated photovoltaic storage and thermal power projects with multi-energy complementarity.
