VGC can provide Parabolic Trough Solar Collector systems,Mainly 5 types Solar concentrating systems:

Parabolic Trough Solar Collector/ Sterling Solar Dish Collectors/Tower Solar Plant/ Fresnel Solar Concentrating system/Composite Dish Concentrating Solar Systems/

The parabolic trough Solar collector technology is a device that reflects and focuses the sunlight on the heat collector tube with the help of a trough parabolic reflector, and heats the heat transfer fluid in the heat collector tube. The thermal system heats the water into hot water/steam, and provides a clean energy utilization device with a heat source for the user. The technology is mature, and its collector is a line focusing collector, and the HCE tube has a large heat-absorbing area. The heat transfer fluid is used as the heat-absorbing medium, and the maximum working temperature of the medium is 300 ℃ ; the collectors are installed on ground, which is convenient for installation and maintenance. The biggest advantage is that multiple groups of PTC are arranged in parallel  and can track synchronously, so the tracking control cost is low. While the heat transfer fluid in the collector tube heats and flows, it is also a process of energy concentration.

The system mainly includes solar heat collection system and hot water supply system. The solar collector field is mainly composed of collector loop, collector field pipeline, etc. The loop is composed of SCA. The components of the collector mainly include: reflector, HCE tube, tracking system (including drive, control and sensor), framework, etc. The collector combination is the main function components. Each collector circuit is connected in parallel to form a solar collector field. Each collector combination is composed of several collector units, and each collector combination is equipped with a driving device, which can realize single-axis rotation and drive the collector combination to track the sun. In order to prevent the problem that the fluid of the heat collecting system freezes in winter, heat transfer oil is recommended as heat transfer fluid.

Parabolic Trough Solar Collector

High stability, good safety

Adopt vacuum tube with stainless steel  inner tube, so there won’t  happen tube explosion phenomenon and subsequent water leakage. High performance of resistance to hot and cold temperature shock, High stability.

High heating temperature and temperature rise fast

Its principle is line focusing, concentration ratio is 60:1. Temperature can increase to 150C from room temperature within 5mins.

High collection efficiency

Heating  area  to  heat  dissipation  area  ratio  is  25:1,  it  can  improve  collection  efficiency compared with 2:1 ratio of solar vacuum tube collector. Meantime, the system adopts single axis track heating way, heat-collecting capacity can improve 30%.

Can be used in winter with good frost resistance

Small heat release when used in medium/high temperature, the temperature can reach 150C, can meet the demand of winter heating and drinking water.
