Chinese Academy of Sciences Develops Framework to Assess Global Solar PV Potential
A research team from the Chinese Academy of Sciences has created a framework to evaluate the global solar photovoltaic (PV) potential, assessing technical and economic feasibility at a one-kilometer resolution. The study estimates a global technical potential of 12,956.93 PWh/year and an economic potential of 4,990.20 PWh/year, significantly exceeding current electricity demand. The analysis reveals improved PV affordability from 2013 to 2023, with nearly 99% of existing installations in affordable areas. The framework aids in energy planning for policymakers.

The Chinese Academy of Sciences has developed a global framework to assess solar photovoltaic (PV) deployment potential, evaluating technical and economic feasibility at a one-kilometer resolution. The framework integrates multi-source datasets and estimates a technical potential of 12,956.93 PWh/year and an economic potential of 4,990.20 PWh/year.
PV affordability improved significantly from 24.7% in 2013 to 75.1% in 2023, influenced more by economic factors than solar resource availability. Validation showed nearly 99% of existing PV installations are in affordable areas. The study also notes the challenge of existing PV on cropland and suggests agrivoltaics as a potential solution.
