Self Locking Customized Sizes Worm Gear Small Slew Drive For Solar Tracking System
Solar Slew Drive Description
VE5 solar slewing drive is usually used in PV solar tracking system. It can also used in CSP, such as Fresnel, solar tower/heliostat.
Fresnel concentrated solar power station, the working principle is similar to trough type photothermal power generation, except that the Fresnel structure condenser is used instead of the mirror. This makes it relatively inexpensive, but the efficiency is correspondingly reduced because such a system has only a few times of concentrating, the quality of the heated water vapor is not high, so that the annual power generation efficiency of the whole system can only reach about 10%; but due to the simple structure of the system and the direct use of heat-transfering medium to generate steam, its construction and maintenance costs are also relatively low.
