According to our understanding, flat panel solar collector is a device that absorbs solar radiation energy and transfers heat to working substance. It is a special heat exchanger, in which the working substance exchanges heat with the long-distance sun. These devices are mainly used for active solar heating and allow the heating of water for personal use. Plate solar collectors are made up of heat absorbing plate core, shell, transparent cover, insulation material and related parts. They have fashionable appearance, high performance, multi-function, easy installation and strong field test durability. We offer solar collectors, solar water heaters, enameled water tanks, etc.

What is solar collectors?

A solar collector is a device for collecting and/or concentrating solar radiation from the Sun described. These devices are mainly used for active solar heating and allow heating of water for personal use. These collectors are usually installed on roofs because they are exposed to different weather conditions and must be very strong.

Type of solar collector

There are many different types of solar collectors, but they are all built with the same basic premises in mind. Usually, there are materials that collect and focus energy from the sun and use it to heat water. One of the simplest of these devices is to use black material around the pipeline through which water flows.

Black materials absorb solar radiation very well, and when they heat the water around them. This is a very simple design, but the flat panel can become very complex. Absorbing plates can be used if high temperatures are not required, but devices that usually use reflective materials to focus sunlight lead to higher temperatures.

1.Tube plate type heat absorbing plate

The tubesheet heat absorber is a flat plate solar collector heat absorber plate, which is formed by connecting the exhaust pipe and the flat plate in a certain way, and then welded with the upper and lower collectors. This is the structure type of heat absorbing plate which is widely used at home and abroad.

2.Wing tube type heat absorbing plate

Wing tube heat absorber is made by extrusion and stretching of the die into a heat absorber strip with fins on both sides of the metal tube (such as the right picture), and then welded with the upper and lower manifolds to form a heat absorber plate. Aluminum alloy is generally used as the material of heat absorbing plate of flat solar collector.
The advantages of wing-tube heat absorber are: high thermal efficiency, the tube and the plate are integrated, without combined thermal resistance; strong pressure resistance, aluminum alloy tube can withstand higher pressure.

3.Snake tube heat absorber

Advantages of snake tube heat absorber: no additional welding header is needed to reduce the possibility of leakage; thermal efficiency
High, no combined thermal resistance; clean water, copper pipe will not be corroded; ensure quality, the whole production process to achieve mechanization; strong pressure resistance, copper pipe can withstand higher pressure.
The shortcomings of snake tube heat absorber are as follows: the flow resistance is large, the fluid passage is not parallel but series; the welding is difficult, and the weld is not straight line but curve.

4.Flat box heat absorber

Flat box type heat absorbing plate is formed by pressing two metal plates separately, and then welded into one to form heat absorbing plate. The material of heat absorbing plate can be stainless steel, aluminium alloy, galvanized steel, etc.

Defects of flat box heat absorber plate: welding process is difficult, easy to appear problems of penetration or improper welding; poor pressure resistance, solder joint can not withstand higher pressure; poor dynamic characteristics, large cross section of fluid channel, heat absorber plate has larger heat capacity; sometimes water quality is not easy to guarantee, aluminum alloy and galvanized steel will be corroded.

Guide to purchasing solar collectors

  • Solar flat plate collector is manufactured by laser welding to improve its performance and aesthetics. Laser welding of absorption tubes ensures very high mechanical bonding to withstand high temperature gradients and thermal expansion. These collectors are made of the highest absorption coating in the industry, namely vapor deposition coating.
  • The building aluminium angle inside the collector includes special pin clips and rivets to ensure high stability. Silicon is not used on the collector. Extruded parts of ribbed aluminium alloy and smooth compressed EPDM gaskets provide water tightness. This allows easy access to the collector at any time or place for maintenance or maintenance.
  • The glass washer on the equipment ensures long service life and avoids all water infiltration! It is also equipped with a general installation framework.

What are the types of solar collectors?

  • Vacuum tube collectors are the most efficient but expensive type of hot water solar collectors.
  • Batch solar water heaters, also known as integrated collector-storage systems, have tanks or pipes in the insulating box, glazed on the south side to capture the energy of the sun.
  • The flat plate collector is a box covered with glass or plastic and having a metal absorber plate at the bottom. Glass or coatings on absorption plates help to better absorb and maintain heat.

What is a solar collector and how does it work?

The inside of the solar collectoris sometimesevacuated, the energy contained at intervals the solar collect is basicallycornered and therefore heats the agent contained within the tubes. The tubes are sometimesmade up of copper, and also theplate armor is painted black to assist absorb radiation.

What is the purpose of a solar collector?

solar-thermal collectors heating air. A easy solar air collector consists of an absorber fabric, from time to time having a selective surface, to seize radiation from the solar and transfers this thermal power to air through conduction heat transfer.

What are disadvantages of solar collectors?

dangers of solar electricity,The unpredictability of fossils fuels has spooked large players within the power region into exploring opportunity, renewable and cheap sources of power. the largest funding is visibly slanting toward sun, wind and hydropower. whilst hydropower still regulations the energy world, solar gives a clear preference for inexpensive power stepping into the future.

So, what is solar strength? it is power derived from the sun. Renewable electricity technology including solar cells and sun panels are used to harness the sun’s energy to provide mild, warmness, hot water and technology of power for houses, organizations, and industries
