Product Description:

Application:

Our flat plate solar thermal collector is suitable for residential or commercial solar water heating projects, such as hot water for real estate, hotel, factory hospital, school, swimming pool, central heating, floor heating, etc. 

 

Warranty:

5 years international warranty for Flat Plate Solar Collector due to original quality problems.

 

Component Description:

Flat Plate Panel Solar Collector is one of the most wide-used solar collector with high efficiency, the selective coated absorber sheet absorbs up to 95% of available sunlight converting into usable heat, the heat is normally absorbed by water in the loop, or a freeze-resistant water mixture which is used to supplement hot water heating or house air heating.

--Glazing Glass: Toughened low-iron glass (glazing) protects the absorber from the outside environment while allowing through more than 91% of sunlight.

--Absorber: A thin sheet of aluminum is coated with a highly selective anodic oxidation / black chrome / blue titanium coating that is extremely efficient at absorbing sunlight and converting it into usable heat. The aluminum sheet is ultrasonically welded / laser welded to the copper riser pipes.

--Insulation: The insulation helps reduce heat loss from the sides and back of the collector. High-density polyurethane and glass wool to greatly reduce weight and heat lost of the collector.

--Riser & Header Pipe: Conforms to international standards, the header and riser pipes are brazed together to form a harp shaped heat exchanger that the solar system water or fluid circulates through. The absorber sheet is ultrasonically welded / laser welded to the riser pipes, thus transfers heat to the water or heat transfer fluid.

--Casing: Anodized aluminum alloy sheet seals the back and frame of the panel and adds to the rigidity of the collector. The rails in the frame are designed for easy mounting attachment.

Q:What is the classification of solar collectors?
According to whether the collector is tracking the sun is divided into: tracking collector, non-tracking collector according to whether there is a vacuum within the collector is divided into: flat-type collector, vacuum tube collector.
Q:The introduction of flat solar water heater
Flat solar water heater is a small high-rise residential supporting the design and development. The water tank is placed on the balcony, roof, wall and other places.
Q:What is the working principle of flat solar collectors?
The basic working principle of flat solar collectors is very simple. Generally speaking, the sun through the transparent cover plate to the surface coated with absorbent layer on the heat absorber, in which most of the solar radiation can be absorbed by the absorber, into heat, and to the fluid channel in the working fluid.
Q:What is a trough solar collector?
Because of the different use, the collector and its matching system type is divided into many kinds, the name is also different, such as cooking for the solar cooker, used to generate hot water solar water heater, dry items for the solar dryer, for Melting metal solar furnace, as well as solar houses, solar thermal power plants, solar desalination and so on.
Q:The characteristics of flat solar collectors
Flat solar water heater advantages: First, particularly suitable for integration with the building requirements. Flat solar water heater because of its structural characteristics of the plane, in the integration of solar energy applications, the shape of flexible structure, the design is not subject to the shape or size of the constraints,
Q:How can solar collector system prevent wind?
The collector must be provided with proper wind protection, bolted or secure. Other components of the solar thermal water system are affected by the wind may cause damage or affect the normal operation of the system,
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
The absorption ratio α and the emission ratio ε of the black chromium coating are 0.93-0.97 and 0.07-0.15, respectively, and α / ε is 6 to 13, and has excellent spectral selectivity.
Q:What is the principle of thermal conversion of solar collectors?
The most common solar collectors are non-concentrating flat type collectors. Its heat absorber body is basically flat shape, the area of heat absorption and the lighting area is approximately equal, its structure as shown in Figure (a) is the use of greenhouse effect of non-concentrating type collector. Enriched CO2 in the greenhouse can improve the greenhouse effect. Condenser type collector using the principle of focusing, that is, the use of light reflection and refraction principle, the use of reflectors or refractors to change the direction of the sun, the sun focused on the heat sink in the small area of the heat absorber, increase the unit area Of the radiation intensity, so that the collector to obtain a higher temperature.
Q:With the tonnage of solar collectors and air to hot water which power consumption
resulting in no hot water in the rain and snow weather; and air to hot water works relative It is not affected by the sunshine, theoretically can be used throughout the year.
Q:Where is the solar collector installed in the building?
Hello, the location of solar collectors have different species, can be placed on the roof, the angle is generally 45 degrees, you can put on the south wall and building integration, selected as a satisfactory answer Thank you!
