Construction of photovoltaic power station support

What is a PV support structure?

Support structures are the foundation of PV modules and directly affect the operational safety and construction investment of PV power plants. A good PV support structure can significantly reduce construction and maintenance costs. In addition, PV modules are susceptible to turbulence and wind gusts, so wind load is the control load of PV modules.

How to characterize the development of PV power stations?

Characterizing the Development of PV Power Stations Based on the long-time series of medium-resolution satellite images, we used the Random Forest model and LandTrendr algorithm to identify PV power stations and their construction years.

Do PV power stations change vegetation condition before or after construction?

To assess the ecological impact of PV power stations, we used the NDVI to measure the change in vegetation condition before and after the construction of PV power stations and constructed NDVI changes for PV power stations constructed in different years.

Why is photovoltaic installation important?

Document and Document record that photovoltaic installation not only overcomes the problems of large-scale centralized photovoltaic power station occupancy and maintenance, but also has the advantages of local power generation loss, reduction of civil construction and installation costs, and power saving.

Why is it important to understand the ecological impact of PV power stations?

For such areas, understanding the ecological impact of the rapid and massive construction of PV power stations is very important for optimizing the layout of PV power stations and protecting the regional ecology.

How to identify the construction time of PV power stations?

Following that, we identified the construction time of the PV power stations by identifying the turning points of the normalized construction land index (NDBI) time series from 1990–2022 using the LandTrendr method.
