High Performance Solar Flat Plate Collector

Product Introduction:

A high-performance flat-plate solar collector is an energy-efficient device primarily composed of four key components: a heat-absorbing panel, transparent cover plate, insulation layer, and outer casing. The system works by converting solar radiation into thermal energy through the heat-absorbing panel, while the transparent cover plate minimizes heat loss from radiation and convection. The insulation layer further reduces heat conduction, enabling efficient heating of the internal working fluid (such as water or air). Compared to traditional flat-plate collectors, this design demonstrates superior advantages in flow channel configuration, thermal insulation materials, heat-absorbing film layers, and structural engineering. These innovations result in higher thermal efficiency, reduced heat loss, and enhanced collector performance. Widely used in solar water heating systems and building heating applications, it stands as a crucial component for achieving optimal solar energy utilization.

Product Features:

Polyurethane foaming high efficiency insulation layer: 35kg/m³ high density polyurethane is used, formed by high pressure one foam process, closed cell rate is more than 95%, effectively lock heat, reduce heat loss, and the insulation performance is stable for a long time.

High transparency low iron tempered glass: ultra-white low iron tempered glass is equipped with a light transmittance of up to 94%±2%, maximizing the introduction of sunlight; combined with double-sided anti-glare coating design, both light transmission and comfort are taken into account.

Aluminum armor body: The frame is made of aviation grade S11 aluminum profile, with tensile strength of ≥160MPa, combining lightweight and high strength characteristics; the surface is used for gray metal drawing process, with outstanding texture and strong weather resistance, which is not afraid of wind and rain erosion.

Multi-scenario plug and play: equipped with 4 G3/4 internal thread interfaces, the construction efficiency is directly increased by 50%, and it is suitable for the rapid installation needs of multi-scenario. 

Application scenarios:

Household hot water/heating: The daily household needs stable hot water supply and winter heating guarantee, the population size is mostly 3-5 people, sensitive to energy costs, this collector can be adapted to different types of heating area, to meet the comfort needs of home life.

Constant temperature of swimming pool: whether it is a private swimming pool or a small commercial swimming pool, it is necessary to maintain the comfortable water temperature of 26-28℃. In a humid environment, the collector can adapt to this condition and match different sizes of swimming pools to achieve stable water temperature.

Hot water/heating for hotels, hospitals and office buildings: With dense population, the demand for hot water and heating is large and concentrated, which requires high stability of equipment and installation efficiency. The collector can be composed into a large-scale system, which can be installed quickly and run stably for a long time.

Industrial preheating: There are many processes in industrial production that need to preheat materials or media. The site environment is complex, and the durability of equipment and the flexibility of heat collection scale are required. The collector can meet the preheating needs of different production scales.

Agricultural drying: In agricultural production, it is necessary to dry grains, fruits and vegetables, Chinese medicinal materials and other agricultural products, which requires high temperature stability of drying, and most of them are carried out in rural areas. The collector can be installed easily and can meet the needs of different drying capacity.
