Product Overview


The flat plate solar thermal panel (also known as solar hot water panel) is a high-efficiency solar collector designed to generate hot water for diverse applications. Engineered with a balanced cost-effectiveness ratio, this panel excels in moderate climates, making it a top choice for both residential and commercial solar thermal energy utilization. Its core function lies in capturing solar radiation and converting it into usable heat, with a daily hot water production capacity of 100-150 liters—perfect for a 3-person household when equipped with the standard 2000×1000mm model. Composed of key components like a high-selective absorber plate, low-iron tempered glass cover, and premium insulation layer, the panel maintains an operating temperature between 30℃ and 60℃, ensuring stable performance for years.

Key Features


High-Selective Absorber Coating

Equipped with black chrome or blue titanium high-selective coating, the panel achieves an absorption rate of 95% and a reflection rate of only 7%. This advanced coating maximizes solar energy capture while minimizing heat loss, ensuring efficient energy conversion even on cloudy days.


Durable Structural Design

The panel features a 1.2mm thick aluminum alloy frame with a sleek black finish, offering exceptional corrosion resistance and structural stability. The 3.2mm low-iron fabric surface tempered glass cover boasts a 90% light transmission rate, protecting the internal components from external damage while allowing maximum solar penetration.


Precision Copper Pipe System

Laser-welded copper pipes form the core of the heat transfer system: 2 pieces of φ22×0.6mm head pipes and 7-8 pieces of φ8×0.6mm or φ10×0.6mm riser pipes. Copper’s excellent thermal conductivity ensures rapid heat transfer, while the laser welding technique enhances leak resistance and durability.


Enhanced Thermal Insulation

A 40mm thick glass wool insulation layer surrounds the absorber plate, effectively reducing heat dissipation. Paired with a 0.4mm stainless steel back plate, the panel creates a sealed thermal environment that locks in heat, even during low-temperature conditions.

Applicable Scenarios


Residential Sanitary Hot Water

Ideal for households, the panel provides a steady supply of hot water for bathing, cooking, and cleaning. A single 2000×1000mm panel meets the daily needs of a 3-person family, reducing reliance on electric or gas water heaters and cutting energy bills.


Swimming Pool Heating

The panel efficiently heats swimming pool water, maintaining a comfortable temperature year-round. Its large absorption area and stable heat output make it suitable for both residential and small commercial pools, lowering operational costs.


Household Heating Support

As an auxiliary heating source, the panel preheats circulating water for home heating systems. This reduces the workload of primary heaters, improving overall energy efficiency and reducing carbon emissions.


Industrial Fluid Preheating

In industrial settings, the panel is used to preheat industrial fluids, reducing the energy required for subsequent heating processes. It is compatible with various industrial systems, offering a cost-effective and eco-friendly solution.


Product Advantages


Superior Cost-Effectiveness

Compared to other solar collectors, the flat plate design delivers higher energy output per dollar invested, especially in moderate climates. Its long service life (over 15 years) ensures long-term return on investment.

The panel adapts to multiple applications—from residential hot water to industrial preheating—making it a versatile choice for different users. It works seamlessly with existing water systems without major modifications.


Easy Installation & Maintenance

With a standardized size and lightweight design, the panel is easy to install on roofs or open spaces. The durable materials and sealed structure minimize maintenance needs, requiring only occasional cleaning of the glass cover.

By harnessing renewable solar energy, the panel reduces reliance on fossil fuels, lowering greenhouse gas emissions. It operates without noise or pollution, contributing to a sustainable lifestyle.
