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.

What is the orientation of a photovoltaic power station?

The overall orientation is due south, with a north-south spacing of 6.87 m and an east-west spacing of 1.55 m. The station consists of 100 strings that form a photovoltaic sub-array, making it currently the largest single photovoltaic power station in the world, with a total installed capacity of 1000 MW.

Why should we use a PV power station map method?

This method helps to quickly map PV power stations and their development trajectory because of its high accuracy and stable algorithm. This method is expected to be extended to other regions in western China where PV power stations are built on a large scale.

Why are photovoltaic power stations being built in Asia?

... Coupled with declines in the prices of solar photovoltaic panels, the requirement for clean energy exponentially boosted the construction of photovoltaic power stations in recent decades in Asia, specifically in the arid and semi-arid regions of northwest China.

Can remote sensing be used to map PV power stations?

To fill the gap, this study proposes an integrated remote sensing approach for PV power stations mapping by combining image segmentation and object-based classification (ISOC) techniques. We took five northwestern provinces of China as an illustration and produced 30-m medium-resolution PV power station distribution maps from 2007 to 2019.

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.
