Solar energy lacks regional photovoltaic power generation

Is there a regional mismatch between PV potential and installed capacity?

China’s PV sector showed a regional mismatch between PV potential and installed capacity. In light of the rapidly expanding solar photovoltaic (PV) sector, it is important to provide a deeper understanding of solar energy resources to successfully implement solar energy projects.

Are solar energy resources and PV power potential based on a GIS model?

Using the dataset reconstructed based on the PSO-XGBoost model, combined with GIS-based approaches and a general solar PV power model, comprehensive assessments of solar radiation resources and PV power potential in China were conducted, while their spatial patterns and spatiotemporal variability characteristics were elucidated.

Is solar PV a competitive source of new power generation capacity?

Solar PV is emerging as one of the most competitive sources of new power generation capacity after a decade of dramatic cost declines. A decline of 74% in total installed costs was observed between 2010 and 2018 (Figure 10).

What is the theoretical potential for PV power generation?

Theoretical potential for PV power generation is best characterized by the long-term distribution of solar resource, in other words, the ‘amount of fuel’ available for PV electricity generation at a given loca-tion.

Does solar radiation affect PV power generation in Xinjiang?

Solar radiation is the dominant factor in the potential for PV power generation in each grid. The results show that the theoretical potential of PV power generation increases as we move from northern Xinjiang to southern Xinjiang ( Figure 6 ).

Is solar energy a future energy resource?

The utilization of renewable energy as a future energy resource is drawing significant attention worldwide. The contribution of solar energy (including concentrating solar power (CSP) and solar photovoltaic (PV) power) to global electricity production, as one form of renewable energy sources, is generally still low, at 3.6%.
