Does solar radiation affect China's solar power potential?

Long-term solar radiation datasets were reconstructed across China. Global solar radiation in summer decreased by up to 1.83 W·m −2 ·decade −1. China’s PV power potential decreased by 1.69 kWh·m −2 ·decade −1 from 1961 to 2016. 30 provinces saw a 0.25–10.27% reduction in PV potential in the 2010s versus the 1960s.

Can daytime radiative cooling and photovoltaic power generation work together?

In a recent issue of Cell Reports Physical Science, Zhu and colleagues unveil a system that remarkably achieves simultaneous daytime radiative cooling and photovoltaic (PV) power generation within the same spatial footprint, establishing a new strategy to unlock the full potential of both renewable energy sources.

How did solar energy change in China in summer?

Global solar radiation in summer decreased by up to 1.83 W·m −2 ·decade −1. China’s PV power potential decreased by 1.69 kWh·m −2 ·decade −1 from 1961 to 2016. 30 provinces saw a 0.25–10.27% reduction in PV potential in the 2010s versus the 1960s. China’s PV sector showed a regional mismatch between PV potential and installed capacity.

Are solar radiation resources available in China?

In this study, the theoretical solar radiation resources in China were assessed based on the assumption of the long-term availability of solar radiation at any site and indicated in terms of global horizontal irradiation, i.e., GSR. Fig. 11 a shows the spatial distribution of the annual mean GSR from 1961 to 2016 in China.

How much solar power can China generate a year?

The average yearly potential for solar power generation in China from 1961 to 2016, assessed with global horizontal radiation data from the PSO-XGBoost model, reached 285.00 kWh·m −2.

What causes a reduction in solar radiation resources in China?

Interestingly, these areas are also characterized by the most severe air pollution, which has been suggested to be a primary cause for the reduction in solar radiation resources . Fig. 13. Spatial pattern of GSR trends in China for (a) 1961–1990, (b) 1990–2016, and (c) 1961–2016.
