Applications
Concentrated solar power-CSP
The core of the solar thermal power generation and heat collection
technology is concentrating light, so its requirements for the day
tracking system are higher than those of photovoltaic power
generation. The difference between the two is that photovoltaics
can be tracked in one or two axes, and depending on the specific
technical route of CSP, the requirements for the form of tracking
are also different. For example, trough technology can only use
single-axis tracking, and tower technology must use dual-axis
tracking. In terms of tracking accuracy, the CSP tracking system
has higher accuracy requirements, ranging from 0.03 degrees to 0.05
degrees, while photovoltaic power generation tracking has less
stringent requirements for accuracy, and about 0.1 degrees can
fully meet the requirements.
