PVT Solar Systems Combine Solar Power and Heat for Maximum Efficiency

PVT Solar Systems Combine Solar Power and Heat for Maximum Efficiency

A breakthrough in renewable energy technology, Photovoltaic Thermal (PVT) systems integrate solar electricity and heat generation in one unit. Unlike traditional solar panels, PVT hybrid solar panel modules produce both electricity and hot water, maximizing the utilization of solar radiation. This dual-function system is gaining traction in commercial buildings, hotels, and industrial projects where both power and hot water are required. Experts believe PVT will play a vital role in the future of smart energy systems, helping reduce carbon emissions while optimizing space and cost. As global demand for high-performance renewable solutions rises, PVT technology stands out as a game-changer.

I. Product Introduction

580W E-type PVT Thermal Power Combined Panel is a new generation of highly efficient photovoltaic-thermal integrated equipment. The core adopts precise laminated integration technology, integrating photovoltaic power generation and solar heat collection in the same module. Unlike traditional photovoltaic panels that only generate electricity and ordinary solar thermal equipment that only produces hot water, PVT hybrid solar panels can simultaneously output electrical energy and thermal energy, achieving more efficient utilization of solar radiation.

This product is particularly suitable for scenarios that require both electricity and hot water. In commercial buildings, hotels, factories, schools, greenhouses, swimming pool heating and other projects, it has obvious comprehensive advantages. By recovering the heat generated by photovoltaic components, the system not only can produce usable hot water but also can lower the working temperature of the battery, helping to stabilize power generation.

II. Technical Parameters and Principles

1. Technical parameters 

Application Scenarios: Commercial buildings, hotels, factories, campuses, greenhouses, swimming pools, etc.

Specification of PVT

Remark:

1. Integrated, high income: photoelectric, photothermal integrated coupling design, make full use of solar energy resources, the same   area of more income.

2. Reliable and long life: reduce the working temperature of the surface of the solar module, improve the working condition, extend the service life and obtain more power generation

3. Precision, high performance: The use of half a single crystal multi-main gate N-type TOPCon battery, partition temperature and no hidden crack laminated heat transfer process, close-packed heat exchange runner layout, two EL detection, two air tightness detection, one insulation resistance test, excellent process stability.

2. Working Principle

The core principle of the 580W E type PVT system is the comprehensive utilization of photovoltaic and thermal energy:

1. When sunlight hits the surface of the PVT panel, some of the light energy is converted into electrical energy through the N-type TOPCon cells;

2. During the power generation process of the photovoltaic module, heat is generated, causing the module temperature to rise;

3. The built-in copper channels carry away the heat through a circulating medium, reducing the battery temperature and minimizing the degradation caused by high temperatures;

4. The recovered heat is further converted into usable thermal energy, which is used for hot water supply, heating, or other process heating;

5. Ultimately, a dual output of "power generation + heat production" is achieved, enhancing the overall utilization rate of solar energy.

IV. Product Advantages

1. Dual Output of Photovoltaic and Thermal Energy

A 580W E-type PVT panel can generate both electrical energy and thermal energy simultaneously. The comprehensive energy utilization rate can reach up to 88%, which is more efficient than traditional single photovoltaic systems in fully utilizing solar energy.

2. Enhanced Reliability through Laminated Technology

The integrated laminated structure ensures a tighter combination of the photovoltaic layer, heat absorption layer, and heat exchange channel, reducing interlayer thermal resistance and improving heat exchange efficiency and structural stability.

3. Lower Photovoltaic Temperature and Stable Power Generation

By removing heat through a circulating medium, the component operating temperature becomes more controllable, reducing power loss caused by high temperatures, especially suitable for areas with intense sunlight.

4. Savings in Installation Space

The PVT system integrates photovoltaic and thermal functions in a single module, reducing roof area occupation and suitable for projects with limited space but requiring both electricity and hot water.
