Type of Solar Collectors

The classification of solar collectors is based on the way they collect solar radiation. Although the decentralized type absorbs radiation on the surface of the collector, the concentrated type first increases the concentration of radiation per unit area before absorption. Furthermore, based on the technology for radiation aggregation, the type of focusing can be further divided into a focus type and a non-focus type. According to the focusing method, the focus type is further subdivided into a line focus and a point focus.

Types of solar collectors used herein are parabolic trough collectors and molten salt heat stores. The parabolic trough collector is the most common type of solar thermal power plant. One of the main reasons is to use lenses to concentrate sunlight on the battery, thus reducing the amount of expensive semiconductor material PV material while collecting sunlight. Is possible. The parabolic trough collector uses mirrors on the north and south axes and tracks the sun as the sun moves. The mirror reflects sunlight onto the tube and the tube extends along the length of the collector. Such tubes are called absorption tubes and are filled with fluids that absorb condensed solar radiation and can reach temperatures of up to 400 ° C. The collector region consists of hundreds of these collectors connected together, called circulation and collection, and then transmits heat to the steam generator or regenerator (molten salt). (See Figure 2-2)

There are two types of solar collectors used in SHW: vacuum tube collector and flat plate collector. They have different configurations, but they have the same function. The vacuum tube collector contains vacuum tubes of various sizes of high heat insulation and exchangeable which are necessary for home heating. In the flat panel, heat is installed in the room to absorb energy and produce energy. The 123 Zero Energy special solar water heater system is very useful if you live in the Arctic and need effective heating technology to support your daily life. They not only survive at Arctic temperature, but also ensure maximum heating when the pump is switched off / on as needed. To enjoy hot water baths and laundry services at your home, reduce energy costs and order 123 Zero Energy's home solar hot water system now!

An effective way to sustain energy is to use solar energy. A parabolic trough collector with a central receiver is one of the most suitable systems for solar power generation. A concentrating solar collector that collects sunlight on a light receiving tube including a working fluid such as water and oil arranged along the groove's focal line by using a U-shaped groove. A transparent glass tube may surround the receiver tube to reduce heat loss. For parabolic troughs, usually one- or two-axis tracking is used. The temperature of the receiver may reach 400 ° C. The heated working fluid can be used in a medium temperature space or process heat or can be used to operate a steam turbine for power generation or power generation. To provide high efficiency at high temperatures, high performance solar collectors are needed. Line focus concentrator
